I've heard you need fats to properly absorb a lot of the vitamins in vegetables. I personally eat veggies sometimes as snacks between meals -- with no fat. Would it be wise to try to include some fats with this? Interested in what amount of... (more)

A thing to keep in mind: Biology is not efficient. Why would we effectively need to absorb them? They likely ate manyfold as much pro-vitamin A as we do now. Even poor converters would have enough given that level of consumption.

I've heard omega 3 and 6 compete for the same receptors, so they should be ingested apart from one another. Is this true? What about other fats such as coconut or saturated fats?

I don't think it's related to absorption, but rather the downstream receptors for converting PUFAs into signaling molecules show competition between omega-3s and omega-6s. If you look at most food, you'll see that the overwhelming majority of... (more)
