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

Dioxin in Salmon Presents Serious Health Concerns

salmonAs 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.

For those of you wondering how to strike the right balance, I’ll recap the current science on sunlight, vitamin D and health.  Continue reading
