Breast cancer screening has long been a cornerstone of women's healthcare. With 1 in 8 women diagnosed with breast cancer in their lifetime1, the United States Preventive Services Task Force (USPSTF) has developed screening recommendations to help detect early-stage cancer. Notably in 2023, the USPSTF revised the recommended age for biennial mammogram screenings for women with average risk to start at age 40 instead of 502, estimated to result in 19% more lives being saved3 by starting screening earlier. While initiating screening at an earlier age offers advantages to a wide demographic, concerns about the potential of over-screening prompted research into the feasibility of identifying women with lower breast cancer risk who could safely delay mammograms. While guidelines address high-risk individuals, a notable gap exists in providing recommendations tailored to those at lower risk. To gain insight into a patient's risk level, physicians are able to utilize genetic testing to understand an individual's genetic makeup, providing precise insights into their predisposition to various health conditions, including breast cancer. Armed with this genetic information, healthcare providers could craft tailored screening strategies that align with an individual’s specific risk profile. This genetic risk-based approach underscores the value of genetics in individualizing the onset of screening to help avoid over-screening and its associated costs. Surprisingly, genetic information is not currently being widely utilized to identify women at risk of breast cancer or other diseases in clinical practice, despite its potential to make a significant positive impact for patients. A recent retrospective analysis of 25,591 women from the Healthy Nevada Project4 sheds light on the potential benefits of this genetic risk-based approach. The study classified 2,338 (9.1%) of these women as having a low genetic risk for breast cancer. What's remarkable is that these women exhibited a significantly lower and later onset of breast cancer compared to their average or high-risk counterparts. This finding suggests that it might be safe for low-risk women to delay mammogram screening by 5 to 10 years without compromising their health.

February is American Heart Month. While cardiac care is crucial every time of year – especially as heart disease stays the number one killer in the United States – American Heart Month serves as a great reminder to stay on top of your heart health. We spoke with Malina Ruiz, a cardiology nurse practitioner at Renown Health, on three key ways to embrace heart-healthy living and how genetic screening can help inform you of certain genetic risks that can play a role on the cardiac life stage.  1.  Invest in a heart-healthy diet. Eating a diet that is rich in fruits, vegetables, whole grains and healthy fats (including monounsaturated fats such as avocados and polyunsaturated fats such as sunflower oil) is a key defense in protecting your cardiac health, according to Malina. While you are filling your plate with these nutritious foods, remember to keep an eye on your saturated and trans-fat intake, and try limiting foods that are high in those fats.   “No matter what age we are, maintaining a heart-healthy diet will always be important,” said Malina.    Need help finding cardiac-friendly meals? The National Heart, Lung and Blood Institute makes it easy with heart-healthy recipes and tips from experts.  2.  Do an exercise audit. “Keeping an active lifestyle during our younger years is one of the most important factors that affect heart health in future years,” said Malina. Maintaining a regular exercise regimen that allows you to raise your heart rate and break a sweat can help prevent future cardiac events.     A good rule of thumb is to aim for 150 minutes a week of moderate-intensity exercise, which averages out to 30 minutes a day on 5 days out of the week.    It’s never too late to start a regular exercise routine! Exercise doesn’t have to be something you dread – leverage American Heart Month to find activities that you enjoy. The American Heart Association can help you discover new ways to move your body. At the end of the day, as Malina emphasizes, “any movement is better than nothing!”  3. Don't skip those check-ups. Regular preventative visits with your primary care provider can help you identify possible risk factors for heart conditions before they start actively affecting your life. “Check-ups become even more important as we age, along with being aware of the signs and symptoms of heart disease, heart attack and stroke,” added Malina.     There’s no time better than the present – call our expert scheduling team today at 775-982-5000 to request a preventative check-up with your primary care provider.

What exactly is the relationship between genetics and disease? Powered by Renown Health, the Healthy Nevada Project is one of the most visible genomic studies in the United States. They are recruiting participants here in northern Nevada to understand the relationship between genetics and nonalcoholic liver disease. Joseph Grzymski, Principal Investigator at the Healthy Nevada Project and Chief Scientific Officer at Renown Health, shares why this study is so important and who should take part. Many people are aware that heavy drinking can lead to liver disease. Yet they are unaware that other types of liver disease are not caused by alcohol consumption. These types of liver disease are more difficult to diagnose but are equally dangerous. What is NASH? A build-up of fat causes nonalcoholic Fatty Liver Disease (NAFLD) in the liver. The most dangerous form is called Nonalcoholic Steatohepatitis (NASH). It causes inflammation and damages liver cells, leading to fibrosis, scarring of the liver, and decreased liver function. If NASH goes untreated, irreversible liver damage can occur, leading to cirrhosis, cancer, or liver failure. These conditions can be fatal. What’s most concerning about NASH is that the symptoms don’t typically cause pain and aren’t noticeable. The good news is that a new local study is raising awareness about this disease by recruiting at-risk people for NASH. Am I at risk for developing NASH? The following factors put you at risk: Obesity Type 2 diabetes Metabolic syndrome High blood lipids, such as cholesterol and triglycerides Does having a family member with nonalcoholic liver disease increase my risk? We do not know a lot about inheriting NASH, although a lot risk factors run in families. One goal of this study is to better understand the genetic component of NASH. There are certainly other risks too, such as environmental and behavioral risk factors. However, we don’t yet have a good grasp on how these impact NASH risk. How is NASH diagnosed? Diagnosis is traditionally done with either a liver ultrasound or biopsy. However, both procedures are expensive and the invasive biopsy has risks. Therefore doctors often use risk factors or less invasive blood tests for diagnosis. This NASH study will include a new blood test called the enhanced liver function (ELF) test. Doctors and researchers have data suggesting that the ELF test is a better diagnostic test for NASH risk. Conducting this cutting-edge test with study participants allows them to share results with their doctors to ensure the best care. What can I do to reduce my NASH risk? Limiting exposure to the risk factors of NASH often lowers risk. Eating a healthy diet, maintaining a recommended weight and exercising regularly can proactively lower your risk.

The Healthy Nevada Project (HNP) is one of the most visible genomic studies in the United States, and guess what? Renown Health powers it! The Healthy Nevada Project (HNP) aligns with Renown's goal to do the best for our patients. The genomic study is at no-cost for Nevadans and gives participants insight into different genetic traits, including results on three prevalent and serious health conditions known as CDC Tier 1 conditions. CDC Tier 1 Conditions Include: Hereditary Breast and Ovarian Cancer Syndrome (HBOC) Lynch Syndrome Familial Hypercholesterolemia (FH) Not only does HNP give participants insights into their genetic background, but it also facilitates Renown's ability to study population health. Research lays the foundation for the future of medicine, and Renown's HNP is on the cutting edge of genetic research. We do this by providing skilled researchers access to studies for the diseases that currently have limited treatment, including nonalcoholic steatohepatitis liver disease or NASH. For example, the observational NASH study helps researchers understand genetic links to the disease. Make an Appointment to Get Screened If you haven't already, join the over 55,000 HNP participants and make an appointment to have yourself screened.

Colorectal cancer is the number two cancer killer in Nevada, only second to lung cancer, yet it is also one of the most preventable. Still, in 2020, 20.7% of Nevadans said they had never been screened for this deadly disease, according to the Nevada Cancer Coalition. At the start of the COVID-19 pandemic, unfortunately many healthcare services were halted, including colorectal cancer screenings. Those delays in screenings can lead to delays in diagnoses of colorectal cancer, resulting in poorer outcomes. Per the American Cancer Society, if colorectal cancer can be found early the relative 5-year survival rate is approximately 90%. Screening is key, and it is important to engage in preventative care. Even if you have no personal or family history of colorectal cancer, ask your doctor about colorectal risk factors and when to start screening, and if you’re up to date on your screenings, talk to loved ones and make sure they are too. According to the American Cancer Society, most colorectal cancer cases are found in those without a family history. This month let us help raise awareness for colorectal cancer and the importance of routine, life-saving screenings. To learn more, we spoke to Renown Health oncology nurse Christina Alsop, APRN. What is Colorectal Cancer Colorectal cancer is a disease in which the cells in the colon or rectum grow out of control. It usually forms from precancerous polyps, or abnormal growths, in the colon or rectum, which can become malignant without presenting any symptoms. How do Screenings Work Screening tests like stool tests, colonoscopies and others can detect these precancerous polyps, so they can be removed by a physician before turning into cancer. Screening tests can also find colorectal cancer early, resulting in better treatment outcomes. As of 2021, the U.S. Preventative Services Task Force recommends adults begin colorectal cancer screenings beginning at age 45, through 75. Screening methods include a blood stool test, which needs to take place every year or a colonoscopy, which takes place every 5-10 years. Healthy Habits Can Help Stave Off Risk Routine screenings are the only way to determine colorectal health, yet some healthy habits may reduce your risk for colorectal cancer. These factors include maintaining a healthy weight, being physically active, eating a diet rich in fresh fruits, vegetables and whole grains, limiting alcohol intake and not smoking.

If you’re a parent, you’ve probably been there — the sometimes-nightly struggle to get your little ones off to bed. Elaina Lantrip, an APRN with Renown Pediatrics, offers some tips and explains how your child’s electronics may be getting in the way of a good night’s sleep. These days, kids are consuming media from a very early age on all types of devices — from tablets and phones to TVs. While they can benefit from some media use, it can have a negative impact on bedtime. We asked Elaina Lantrip, an advanced nurse practitioner with Renown Pediatrics, for some advice on downloading a better bedtime routine. What are the most important practices for parents to establish for their children’s bedtime routines? I often have parents tell me that their child won’t go to bed — or to sleep. Parents frequently ask for tips on bedtime routines that work. My first question is whether their regular bedtime routine involves television, iPad, tablet, phone or anything with a screen. It’s very important that bedtime includes a bath, reading a story, talking, singing and bonding with young ones, rather than using any devices. Why shouldn’t children have a device at bedtime? A growing body of research supports that screen time at bedtime contributes to delays in a child’s falling to sleep; overall inability to reach the important REM, or deep sleep; waking up during the night; nightmares and night terrors. For older youth, engaging with social media before bedtime can bring up stresses, emotions and relationship issues with peers that don’t exactly create peaceful bedtime thoughts. Bedtime should be a screen-free, stress-free, peaceful time of day. It’s a great time for parents to promote self-esteem, talk through things going on in the child’s life, to encourage and build them up. Children grow up fast — bedtime is a great the opportunity with younger children to cuddle up and read a story or sing a lullaby. What are other major considerations in making bedtime smooth and relaxing for kids and their parents? Another factor that contributes to positive sleep habits includes children getting enough activity during the the day so they’re genuinely tired at night. Also helpful are ambient noise makers, peaceful music, avoiding sugar two hours prior to bedtime, consistency in bedtime routine, comfortable pajamas and comfortable temperature in the home. Is it important to keep the child’s bedroom dark? Dimming the lights is important, regardless of the time of year. This is another reason to ban screens, as they emit light that stimulates wakefulness.

Dr. Max J. Coppes, Physician-in-Chief Renown Children’s Hospital, and Nell J. Redfield Chair of Pediatrics, UNR Med, talks about how much is too much when it comes to teens and social media. Social apps (Facebook, Instagram, Twitter, WhatsApp, Snapchat, TikTok, etc.) have become an integral part of most people’s lives. In contrast to traditional media — where one source goes to many receivers — social media operates in a dialogic transmission system. Many sources interact, sometimes simultaneously, with many receivers and provide for superior interactivity between its users. Not surprisingly, it also plays a significant role in our children’s lives once they are old enough to understand how to access and use these apps. On average, children start exploring social media at around ages 10 to 12. They rapidly discover that electronic communication allows for unique and personalized ways to make and keep friendships. They also use it to develop and expand family ties, get help with homework, share music, art, and experiences, and learn and discover the world. Social Media and Teens Surveys suggest that more than 90 percent of teenagers use social media. Additionally, approximately 75 percent have at least one active profile by age 17. Access to social media is greatly facilitated because more than two-thirds of teens have their own mobile devices with internet capabilities, a substantial change relative to previous generations. The use of social apps can have many positive aspects. But we now also recognize that it can also have negative impacts. The use of hazardous sites or the inherent risks of using social media (identity theft, being hacked, cyber-bullying, etc.) are indeed damaging to children. Any use of hazardous social apps is too much and carries serious hazards. But what about the use of “normal” and/or “safe” social media? Well, data suggest that too much use of “non-hazardous” apps can indeed affect health. How Much Do Teens Use Social Media? First, some basic data. For example, how much do normal teenagers use social media? A study from Pew Research found that more than 50 percent of 13- to 17 year-olds go online several times a day. This quickly increases during the teenage years to more than 70 minutes per day. Teenage girls have the highest usage at just over 140 minutes per day. It is important to recognize that non-school related use of the internet and social media is often beheld by teenagers as important for developing their self-esteem, their acceptance among peers, and their mental health in general. As parents, we recognize that the use of social media can indeed contribute, in many positive ways, to our children’s growth. At the same time, we also worry about them spending too much time online. We worry about their ability to communicate effectively in face-to-face settings or in writing. Many of us also feel and/or worry that our children are addicted. Social Media and Addiction Recent studies suggests that the overuse of social media indeed mirrors addiction. Reports now show that teenagers and college kids experience anxiety when deprived from their connected devices and consequently feel a compulsion to access their social applications. The emotional symptoms they experience are very similar to those seen in substance abuse. In fact, the American Psychiatric Association is considering making internet addition a bonafide diagnosis. Pediatricians therefore encourage limits on the use of social media, a recommendation more easily suggested than accomplished. So when should a parent consider seeking help? Aside from unhealthy use of these apps (cyber-bullying, sexting, online users asking for sexual relations, etc.), which should always trigger concern, the use of social media for more than 120 minutes per day should trigger parental concern. If you feel unable to address the overuse of social media, contact your pediatrician for help and guidance.

In 2018, Jordan Stiteler became a Healthy Nevada Project advocate. Her DNA results revealed that she had Familial Hypercholesterolemia (FH). FH is a genetic condition that can cause high cholesterol. Since then, Jordan’s taken action to lower her cholesterol and make her family aware of this potentially dangerous condition. Read Part I of Jordan’s story Taking Control of High Cholesterol Looking at Jordan, an active young mother, you would never suspect she has high cholesterol. However, because of FH, Jordan’s cholesterol levels are unusually high. She chose to take action when learning of her FH gene, in order to maintain her long-term health. Jordan started by exercising more and eating healthier. “I’ve definitely been checking all the labels to see if the food has a lot of cholesterol, trans fats, or saturated fats,” she explains. She now eats a 100% plant-based diet which helps to lower her cholesterol naturally. Additionally, Jordan partnered with Dr. Michael Bloch, a lipid specialist, to monitor and manage her cholesterol. She told Dr. Bloch that she and her husband were planning on having a second baby. With this in mind, he helped Jordan create a plan to accommodate her pregnancy. Several months after giving birth to her beautiful daughter Logan, it was time to revisit her cholesterol treatment plan. Dr. Bloch prescribed Jordan a statin called Lipitor. It successfully cut her total cholesterol by half in just three months. “I had blood work done in November 2019 and my total cholesterol was 293 (normal is less than 199). I started taking cholesterol medication in February 2020. I had blood work done in June 2020 and my total cholesterol was 149, ” Jordan shares. “My LDLs went from 219 to 78! I am so grateful that the medication worked so well and so quickly! It’s a weight lifted off of my shoulders.” Although Jordan no longer limits herself to a strictly vegan diet, she is mindful of what she eats and how it affects her cholesterol. She’s thrilled that her cholesterol is now at a healthy level!

Your mother had breast cancer. Your uncle had colon cancer. A cousin has stomach cancer. Could yours be the next name to make the family cancer list? “Possibly,” says Dr. Robert Nathan Slotnick, MD, PhD, Medical Geneticist at Renown Medical Group. In this article, the doctor discusses the genetics behind Lynch syndrome — and how you and your family can fight it. What is Lynch Syndrome? Lynch syndrome, also known as hereditary non-polyposis colorectal cancer (HNPCC), is one of the most common genetic conditions known to increase cancer risk in individuals and families. It enables colon and other cancers to develop by causing mutations in mismatch repair (MMR) genes. “The genes MLH1, MSH2, MSH6, PMS2 and EPCAM normally help to repair damaged DNA,” explains Dr. Slotnick. “But when they don’t work properly, naturally occurring DNA replication errors are not repaired efficiently. These errors accumulate and cancer can be the result.” Colon cancer is just one of many possibilities. People with Lynch syndrome also have a higher risk of developing endometrial cancer (cancer of the inside lining of the uterus) as well as cancer of the ovaries, stomach, pancreas, kidney, brain, and bile duct, among others. These syndrome-enabled cancers often appear in patients before the age of 50. Family Cancer Clues The family connection to cancer is a strong one notes the doctor. “Cancer is best considered a genetic disease because it is always tied to changes (or mutations) in our inherited material: our DNA,” says Dr. Slotnick. “These DNA changes cause cells to lose control of their normal constraints on growth and metabolism and can allow abnormalities to develop.” “Although all cancers are genetic,” he adds, “not all cancers are hereditary or passed down through generations.” But because Lynch syndrome IS a hereditary condition, personal and family cancer histories provide invaluable information toward diagnostic confirmation and to a path of surveillance, prevention and treatment. Once a strong family history of cancer is confirmed, doctors and geneticists can move forward with targeted genetic testing to identify specific gene mutations. If Lynch syndrome is diagnosed, testing can also reveal your risk for associated cancers. And your results could be a wake-up call to family members. According to the Centers for Disease Control and Prevention (CDC), close relatives of people with Lynch syndrome have a 50% chance of having similar gene mutations and a higher risk of cancer. The good news is detection and prevention progress is being made. “Lynch is just one of many cancer syndromes where risk is tied to heredity,” explains Dr. Slotnick. “In the last few years, our ability to identify those at risk for this type of cancer predisposition has improved markedly, both in diagnostic accuracy and cost. This allows us to provide aggressive surveillance and prevention choices to individuals and families at risk. Healthier families and lower cost: it’s a win-win.”

Read about Jordan Stiteler, a local mom who says the Healthy Nevada Project provided insights into her family’s genetic makeup — and the likely cause of her dad and great grandfather’s deaths. Now she is changing her life due to her new diagnosis of familial hypercholesterolemia, which will allow her to take steps toward preventing the same fate. Jordan Stiteler’s dad died suddenly of a stroke nearly ten years ago — at only 45 years old. His grandfather died at age 40. Now through the Healthy Nevada Project’s no-cost genetic testing, she is closer to understanding why that may have happened. And she can take proactive steps to prevent the unhealthy symptoms that often lead to a stroke and heart problems. After getting her Geno 2.0 by National Geographic ancestry report, Stiteler got a call from Renown Institute for Heart & Vascular Health Cardiologist and Renown IHI Director of Research, Dr. Christopher Rowan. “They told me that I have FH, which is familial hypercholesterolemia,” she said. “I have genetically very high cholesterol because I have a non-functioning gene that doesn’t get rid of my cholesterol like a normal body would.” Familial Hypercholesterolemia: Simple Life Changes Dr. Rowan told Stiteler it is curable with medication and a change in lifestyle. Stiteler has embraced healthy lifestyle changes by exercising more and eating healthier. “It is so important. Being a mom, I think you have so much more to live for. Having this information has changed my life.” Stiteler feels confident FH affected her Dad. “It is helping my family realize that we need to get tested,” she said. “There were big milestones that my Dad missed. He didn’t get to see either of us get married or have our children. That was huge.” She has become passionate about sharing the need to join the Healthy Nevada Project as her way of helping to prevent other families from possibly going through what she and her family did with the early loss of her Dad. In addition to FH results, the Healthy Nevada Project is returning clinical results on BRCA 1/2 (hereditary breast and ovarian cancer) and Lynch syndrome (colorectal and endometrial cancer) to consenting study participants. To sign up for the Healthy Nevada Project, go to HealthyNV.org. Join the Healthy Nevada Project Recruitment for phase two is still open. In addition to opting in to receive clinical results, participants receive National Geographic’s Geno 2.0 ancestry app at no cost. They also have the chance to pick an additional app for health and wellness after completing a follow-up survey. Learn More or Sign Up

The Healthy Nevada Project – a first-of-its-kind population health study combining genetic, clinical, social and environmental data – has reached another landmark milestone. The study is notifying study participants at risk for familial hypercholesterolemia, BRCA and Lynch syndrome. “I took part in the Healthy Nevada Project to find out my ancestry. I didn’t even realize the test could give me so much information,” says 29-year-old Jordan Stiteler, who was recently diagnosed with familial hypercholesterolemia (also known as FH) through the Healthy Nevada Project. “After my dad passed away suddenly at age 45, I learned I had high cholesterol but I didn’t know it was genetic and I didn’t get an FH diagnosis until last week,” Jordan explains. “I immediately changed my diet, started walking more and doing more cardio. I also set up an appointment with my primary care physician for the first time in a while. I’ve talked with my family and even strangers about testing since my diagnosis. I hope my story will inspire others to test and can save someone’s family from going through the same loss I did.” Healthy Nevada Project Notifying Patients of Familial Hypercholesterolemia Risks Jordan is among the first Healthy Nevada Project participants to receive clinical results from the genetic study led by Renown Institute for Health Innovation (Renown IHI) – a collaboration between Renown and the Desert Research Institute Foundation. This groundbreaking population health study is now reaching out to study participants like Jordan, who asked to be notified of health risks. If study volunteers choose, the project will also provide guidance on treatment and additional testing for family members who may also be at risk. The project is starting with the return of FH risks which is a genetic tie to high cholesterol. Just a few months ago, a paper in the Journal of the American College of Cardiology recommended genetic testing become the standard of care for patients with a definite or probable FH diagnosis. Jordan says she plans to have her young son tested as well. “This is the future of health; not just reacting to sick people, but a coordinated effort between innovative technologies, data-driven researchers, and responsive practitioners to deliver personalized interventions to identify, prevent and treat disease,” says Anthony Slonim, M.D., Dr.PH., FACHE, president and CEO of Renown Health and president of Renown IHI. “As care providers, we often don’t see patients until they’re already sick and that’s a difficult problem. By embracing personal genomics, we can accelerate the ability of researchers to access data and apply those learnings back to our health system sooner.” In the Months Ahead: Notification of BRCA1/2 & Lynch Syndrome Risks The Healthy Nevada Project will start notifying study volunteers at risk for other CDC Tier 1 conditions including hereditary breast and ovarian cancer syndrome (BRCA 1/2 genes) and Lynch syndrome in the months ahead. These conditions are the key focus for the Healthy Nevada Project. The reason: Because early detection and treatment will save lives, and these conditions are some of the most common. “This research allows us to look into cancer, cardiac, respiratory illness and beyond to identify underlying causes, assess real risks and eventually initiate appropriate preventive actions much earlier. Human subject research is often intangible to participants – we are treated as subjects. The Healthy Nevada Project is creating actionable information for our participants while engaging in leading-edge research on health determinants,” said Joseph Grzymski, Ph.D., associate research professor at DRI, principal investigator of the Healthy Nevada Project and chief scientific officer for Renown Health. Landmark Population Health Study Continues to Expand Since launching two years ago, the Healthy Nevada Project has quickly evolved and expanded. The pilot project enrolled 10,000 participants in just 48 hours in September 2016. In March 2018, phase two of project expanded to an additional 40,000 participants with genetic testing partner, Helix. Helix’s genomic sequencing provides participants and researchers greater depth and quality of DNA data. With this, they can gain further insights to improve health. During a recent media roundtable announcing the return of clinical results, the Healthy Nevada Project also announced plans to complete testing of 40,000 people by the end of 2018. This will bring the project’s total enrollment to 50,000 people – approximately 10 percent of northern Nevada’s population. The Healthy Nevada Project hopes to reach more than 250,000 people in its next phase. The ultimate goal is to offer genetic testing to every Nevadan interested in learning more about their genetics and health. Join the Healthy Nevada Project Recruitment for phase two is still open.

Many factors are contributing to the rise of early onset puberty in girls. Learn what they are below and how you can support your daughter. The number of girls experiencing early puberty has increased dramatically over the last few years and continues to grow. More and more girls in the U.S. are starting to show signs of development before the age of 8. Recent studies show that up to 10 percent of Caucasian girls and 23 percent of African American girls are showing signs of puberty by age 7. What’s Contributing to Early Puberty in Girls? Determining the exact cause is difficult. But experts agree that several factors may be contributing to these growing numbers. Increasing rates of childhood overweight and obesity. Excess body fat alters the levels of hormones responsible for the acceleration of pubertal timing. Physical inactivity may decrease melatonin levels, which can also trigger pubertal development. Increased animal protein intake. Higher total protein, animal protein and meat intake in children ages 3 to 7 have been associated with earlier onset of menstruation. High protein intake elevates IGF-1 levels and promotes growth, which could accelerate the onset of puberty. Poor diet. Children with lower-nutrient diets tend to enter puberty earlier. A diet rich in processed foods and meats, dairy, and fast food is disruptive to normal physical development. Exposure to EDCs (endocrine-disrupting chemicals). EDCs are synthetic chemicals found in plastics, pesticides, fuels and other industrial chemicals that inhibit or alter the action of natural hormones. Because EDCs accumulate in the fatty tissues of animals, animal foods contain higher levels of these chemicals than plant foods. Exposure to BPA (bisphenol A). BPA is an industrial petrochemical found in a variety of products including plastics, tin-can linings and even cash register receipts. Because it acts as a synthetic estrogen it may speed up pubertal development. Soy products. Soy contain isoflavones which are converted to phytoestregens in the body, and are similar to the hormone estrogen, Dr. Chelsea Wicks says. “Soy consumed from natural food sources is likely safe and will not cause abnormal hormones levels. However, when consumed in large amounts, such as with soy supplements or in more processed foods, there have been links to chronic medical problems due to elevated estrogen levels. I feel a good answer to this is to continue working on eating fresh foods and trying to avoid the processed, packaged foods as this will be best for overall general nutrition as well,” she adds. What You Can Do While some genetic factors play a role in the early onset of puberty, parents can help lessen environmental causes of the condition. Encourage and help your child to maintain a healthy weight with proper nutrition and exercise. Avoid exposure to hormones such as estrogen and testosterone that may be found in hair products, medications and nutritional supplements. Avoid exposure to EDCs and BPA. Offer your child a diet centered around whole plant foods rather than animal foods, which will help keep protein intake within a safe range and reduce consumption of EDCs. Create a supportive environment for your daughter. Avoid commenting on her appearance and instead focus on her achievements, academic successes or artistic talents. Speak to her openly and honestly about the physical changes she’s experiencing — that although these changes are normal, she’s simply developing early — and that ultimately her peers will undergo the same changes. Encourage your daughter to continue participating in social activities and pursuing her interests, and reassure her you are always open to discuss any questions or worries. If you are concerned that your child may be going through these changes before expected, speak with your pediatrician. Sources: Early Puberty: Causes and Consequences When Is Puberty Too Early?
