We often talk about the amazing nutrition density of organ meat and that they should be part of an optimal diet. How easy is it, in your opinion, to overdo it with organs like liver and get dangerously high doses of Vitamin A? According to... (more)

Ironically, I have never heard of anyone overdosing on nutrients when the nutrients only came from eating real food. My guess would be if you eat liver every day for 2 weeks, you would naturally get sick of it and not want to eat it for a while. ... (more)

Well, I've been reading about Vitamin A and such, and they say that even perfectly healthy people don't convert beta carotene in plants to Vitamin a very efficiently. We would have to eat SO many plants to get a wee bit of vitamin A...UNLESS we... (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.

About 25% of the calories from liver are fat. It's 4 g of fat and 20 g of protein per 100 g liver.

Is anyone here supplementing with hefty amounts of the fat soluble vitamins A (Retinol) D3 and K2-MK-4 (Activator-X)? I know that Weston Price emphasizes this as rather important and I know that Vitamins A and D up-regulate the opposites... (more)

I use Green Pastures cod liver oil and butter oil. I'm not sure what you would consider large amounts, but I take a few teaspoons of each daily. I believe in the WAPF position on vitamin A and D. And I believe that the cod liver oil helps with... (more)

Fat makes a great energy substrate, and it's delicious. Just wanted to say that so no one thought I was hating on the cream or lard. The question is how much do we need. Let's pretend you were meeting your energy requirements another way and... (more)

This is a very difficult question since We will need to agree on a definition of necessity. Maybe 4g/day of EPA/DHA is better than 1g/day in that it lowers risk of CHD by 5% in 90% of subjects, but does that mean we NEED 4g/day? I don't... (more)

I go by how I feel. I do get my D tested once a year and simply make sure I eat a variety of animal foods so I get a reasonable supply of A & K (liver and pastured butter do the trick!) I also supplement 200-400 mg of Magnesium citrate.... (more)

If all of my saturated fat consumption comes from coconut, will i be deficient in those fat soluble vitamins from grass fed meat? Should I even be worrying?
