Europe has suspended some of its oppressive GMO regulations to speed development of a COVID-19 vaccine, drawing accusations of hypocrisy from the scientific community. A growing body of research suggests very low-carb diets could treat Alzheimer’s, ALS and even cancer. Your risk of coronavirus infection and death may be heavily influenced by your genetics—but how big of an influence are we talking about?
Join geneticist Kevin Folta and GLP editor Cameron English on this episode of Science Facts and Fallacies as they break down these latest news stories:
For decades, Europe has so tightly regulated biotech crops that they’re effectively banned on the continent. A single variety of insect-resistant corn is the only GMO plant grown commercially in the EU. Despite these restrictions, ostensibly motivated by concerns for public health and the environment, Europe has suspended some of its rules governing genetic engineering to quickly develop a vaccine for the novel coronavirus. Why would the EU so rapidly drop its rules if biotech plants really pose a serious risk?
The scientific community is always debating the merits of low-carb diets, but these discussions typically center around carbohydrate restriction as a treatment for obesity and diabetes. However, ongoing research suggests that very high-fat, low-carb ketogenic diets may also be viable treatments for a variety of debilitating diseases, most notably cancer. Is this more hype than science, or does such an extreme way of eating really hold promise?
Everybody knows that age and pre-existing conditions boost your risk for severe coronavirus infection. What remains less clear is why some seemingly healthy individuals appear immune to COVID-19 while others quickly succumb to the disease. The answer to this perplexing question may lie in genetics. Dramatic advances in DNA sequencing technology are helping scientists zero in on particular variables—say, blood type or mutations in genes that influence immune function—that may help explain why there are such wide-ranging reactions to coronavirus. Knowledge of these genetic factors could also help fine tune efforts to trace and control the spread of SARS-COV-2, or even develop targeted treatments for the resulting infection.
