 As I've talked about before, to help keep cancer promoting growth factors, like IGF1 in check, we need to maintain an adequate but non-excessive protein intake. I talked about what was excessive, but what's adequate. We used to think that the average person needs about 0.3 grams of protein per healthy pound of body weight, or for those metrically-minded, 0.66 grams per kilogram. So it was easy. You divide your ideal weight in pounds by 3, and that's how many grams of protein most people should average in a day, the so-called EAR, the Estimated Average Requirement, but to be on the safe side they recommended closer to 0.4 per pound for the RDA. Well, recently a group of researchers published a paper arguing that there may be fundamental flaws in the ways protein requirements have been calculated in the past based on some faulty assumptions. Taking that into account, the new recommendations from this group, based on this preliminary evidence, would be about 25% higher. They think most people now probably need about 0.4 grams per pound, and so to be on the safe side shoot 4.5. Well, at least that would make it easy to calculate that would be half of our ideal weight in grams of protein per day, or about 1 to 1.2 grams per kilo.
