During my graduate studies, I realized there was a disconnect between the latest scientific knowledge in the nutrition and genetics fields and the typical dietary advice. I began this blog to inform the public and allow individuals to make better-informed decisions about their dietary choices. Thanks for reading!
During the holiday season, many of us tend to pack on extra fat. However, research has discovered that not all body fat is equal. In fact, some types of fat are beneficial. Here, I describe three types of fat – white, brown and beige – and explain their effects on the body. Continue reading
A recent press release about a study at the University of Melbourne reads “Diabetes expert warns paleo diet is dangerous and increases weight gain.” The headline is based on a study by Dr. Andrikopoulos at the University of Melbourne. Being in my area of research (effects of diet in mice), I looked into this study and was surprised by the misleading nature of the press release. Continue reading
It is known that dietary alterations can cause rapid shifts in weight, but few studies have examined how quickly diet can impact other physiological parameters, especially those related to cancer. A recent study in Nature Communications has identified that diet can have profound health effects in as little as two weeks. The researchers investigated the impact of dietary change on markers of colon health and correlated these changes with shifts in gut microbiome composition. Continue reading
As previously documented, a diet that balances omega-3 and omega-6 consumption seems to be optimal for human health. Today, omega-6 fats are prevalent in our diets because they are in many foods containing seed oils, such as corn and canola oil. To balance the ratio of omega-3 to omega-6, many researchers have encouraged reducing seed oil consumption and increasing fish consumption. Wild salmon is a great source of omega-3 fatty acids and farmed salmon usually has an even higher omega-3 fatty acid content. However, salmon is also has high levels of dioxin, a carcinogen and endocrine disrupter. So, should salmon be included as a part of a healthy diet or avoided because of toxicity concerns?

Rates of type II diabetes are rapidly increasing in the United States. However, the disease is almost completely preventable through dietary and lifestyle modification. Here, I will briefly explain how dietary changes interplay with human physiology to produce the type II diabetes epidemic. Continue reading
Findings from the most recent review comparing the effects of fatty acids on heart disease do not agree with the current US nutritional recommendations. Current recommendations encourage replacing saturated fat intake with monounsaturated and polyunsaturated fats to reduce heart disease risk. The meta-analysis, published in the Annals of Internal Medicine, finds no association of saturated fat intake with heart disease. Continue reading
Protein supplementation has become very popular among athletes and gym-goers. Whey protein, a derivative of milk, is the most popular choice. Soy protein is particularly popular among vegans and individuals intolerant to dairy. However, concerns have been raised regarding soy’s effects on testosterone and estrogen. A study from the University of Connecticut has provided clarity on the effects of whey versus soy protein supplementation on testosterone, estrogen and cortisol levels following resistance training.
