In a review updating the evidence on human exposure and toxicity of pesticides, the body of evidence linking pesticide exposure and cancer is said to be so massive that pesticides’ role in the development of cancer “cannot be doubted.” However, most…
There’s a lot of focus on personalized nutrition, but maybe we should focus on taking personal responsibility for our health. “Personalized nutrition (PN) is rooted in the concept that one size does not fit all,” and who doesn’t want to think they’re special? The idea of personalized nutrition is inherently appealing to our ego; that’s why simple messages recognizing…

Unfortunately, surgical devices are often brought to the market before there is adequate evidence of…
Walnuts, almonds, and hazelnuts are put to the test for erectile and sexual function, sperm count, and semen quality. In 2013, I posted a video based on a study that found that men with erectile dysfunction who ate 100 grams of pistachios (a little more than three handsful) a day for three weeks had “a significant improvement in erectile…
What is the recommended diet for treating leaky gut? Which foods and food components can boost the integrity of our intestinal barrier? Our intestinal tract is the largest barrier between us and the environment. More than what we touch or breathe, what we eat is our largest exposure to the outside world.

Common drugs, foods, and beverages can disrupt the integrity of our intestinal barrier, causing a leaky gut. Intestinal permeability, the leakiness of our gut, may be a new target for both disease prevention and therapy.
