Consuming 20 percent of your total calories from protein equates to 400 calories a day based on a 2,000 calorie diet. As a general rule, between 10 percent and 15 percent of your total calories should come from protein. So, if you consume 2,000 calories per day, at least 200 should come from protein, or about 50 grams.
What is bioavailability? Bioavailability is the ease with which any nutrient can make its way from the food you eat into your body. The bioavailability journey that every nutrient takes is the same. In the first part of the journey, the food must be digested (broken apart) so that the nutrient can be freed from the food that contained it.
Minerals must be in a form that can make it to the cells. Minerals that are not bioavailable just get passed straight through the body. Bioavailability has a precursor which is absorption. To do any good minerals must be absorbed through the intestine walls into the blood stream.he problem is that only 1% to 8% of the mineral supplement is absorbed by the body which makes it an inefficient way of absorbing the correct amount of minerals. Also a lot of the recipients used to bind these cheaper supplements can act as blockers in absorption.
