Are the benefits of hormone replacement therapy worth the risks? Dr. Davis chats with Dr. Avrum Bluming and Dr. Carol Tavris about the pros and cons of taking estrogen during menopause and beyond. Bluming, a breast cancer expert, and Tavris, a psychologist, are both passionate about empowering women to make an informed choice rooted in solid science. In this conversation, they reveal that many common fears around hormone therapy are not supported by the latest evidence, and stem from a misinterpreted study two decades ago. They also explain that hormone replacement therapy can offer far more than just relief from hot flashes, with potential benefits ranging from bedroom to boardroom (cognitive function) to bones and beyond. This episode is the first of a two part conversation. In the second part (coming soon), Bluming and Tavris dive deeply into why the conclusions presented by the Women's Health Initiative Study two decades ago were deeply flawed. Both episodes contain important lessons on how research findings are communicated - or mis-communicated - to clinicians and the public Dr. Avrum Bluming is a hematologist and medical oncologist who has been treating women with breast cancer for forty years.

Dr. Chana Davis chats with Food Science Babe, a food scientist, about the dirty dozen, and all things pesticides. The "dirty dozen" is a list created by the EWG with the stated goal of helping consumers decide "when you should splurge for organic produce". Food Science Babe debunks the dirty dozen, exposing the unscientific methods and pro-organic funding interests behind it. She also sheds light on how pesticides are tested and regulated, and why conventional and organic pesticides are not as different as you think. It turns out that both organic and non-organic fruits and veggies are safe, and that anyone can see this for themselves through publicly available pesticide testing programs (e.g. the US Pesticide Residue Monitoring Program). Food Science Babe has worked in the food industry for over 10 years in both the conventional and organic sectors as a Food Scientist and Engineer. She has a Bachelor's in Chemical Engineering from the University of Minnesota. You can find more of her work on Instagram (@foodsciencebabe), Facebook (@foodsciencebabe) and Twitter (@foodscibabe).

Dr. Chana Davis sits down with Food Science Babe, a food scientist, to talk about processed foods, and why "processed" is not a dirty word. We have all heard it: "Eat whole foods, with five ingredients or less, and ingredients you can pronounce". Is this rule supported by science? In this episode, Food Science Babe explains why a black-and white view of processed foods as "bad" or "toxic" is not only scientifically unfounded but potentially harmful. She highlights some benefits of food processing, debunks common misconceptions around additives, and shares core concepts to help you shift from fear-based to fact-based choices.

Dr. Zoe McLaren sits down with host Dr. Chana Davis to talk about COVID-19 testing.

Dr. Galit Alter chats with host Dr. Chana Davis about what we can expect from a  COVID-19 vaccine, and when they will become available. Dr. Alter is a leading immunologist who studies how we can use our knowledge of the immune system to improve vaccines. This episode of Get Real Health dives into many of the questions surrounding COVID-19 vaccine development. How effective will COVID-19 vaccines be? How long will they protect us? How will their safety be ensured? What types of vaccines are leading the pack? When will they be ready?  While there are no simple answers, Dr. Alter sheds light on what the experts are predicting, and why. This episode is the second part of a two part conversation. The first segment, on the immune response to COVID-19 was released on October 8, 2020. Galit Alter, PhD is a Professor of Medicine at the Ragon Institute of MGH, MIT, and Harvard and co-Director of Harvard's Center for AIDS Research (CFAR). Dr. Alter received her PhD in experimental medicine from McGill University. This interview was recorded on October 2, 2020.

Dr. Galit Alter chats with host Dr. Chana Davis about why COVID-19 infections can be either deadly or invisible - and why age, health, and obesity matter so much. Dr. Alter, a leading immunologist, sheds light on how our immune response to viral infection shapes our fate. Their conversation gets into the science behind these questions: Why do kids tend to escape COVID-19 infection with little to no symptoms? Why are older adults at such high risk of severe disease? What is the biology beneath the other key COVID-19 risk factors (e.g. obesity, hypertension, immunocompromised state)? How does COVID-19 compare to other viruses? The conversation closes with a discussion of "boosting" the immune system and what we should all be doing to protect ourselves. This episode is part one of a two part conversation. The second segment, on vaccine development, will be coming out later this month. Galit Alter, PhD is a Professor of Medicine at the Ragon Institute of MGH, MIT, and Harvard, where she studies the immune response to viral infections, and how to use this knowledge to improve vaccines.
