For today’s edition of Dear Mark, we’ve got a two-parter. First, in light of the recent paper showing that Lactobacillus rhamnosus probiotics given during the first six months of life protects against the development of conditions like ADHD and Asperger’s by age 13, how do you actually give the probiotics to a breastfed baby? It’s pretty easy, as you’ll find. And then, given that acute exercise performed before or after meals seems to change the metabolic response to those meals, would I recommend actually working out every time a person eats? It sounds a little excessive, but it might actually be a good move with some positive effects for people who have trouble with insulin and glucose issues.
