For today’s Dear Mark, I’ve got a three-parter. First I discuss the suitability and proper dosage of grass fed beef liver for babies and toddlers. It’s definitely a good choice, but you do have to keep a few parameters in mind to do it right and do it safely. Next, I discuss flax seed. Is it a good choice? Does it have health benefits beyond the meager conversion of alpha-linolenic acid into longer-chain omega-3s? Finally, I explore what happens when you eat medium chain triglycerides – the fats most prevalent in coconut oil – with fruit or other carb sources. Good, neutral, or certain death?
