The first of the culprit is whole grains.
Whole grains and antinutrients
Unfortunately grains also have another dark side. They are filled with a substance called Phytates which bind to nutrients in your body especially things like; Calcium, Magnesium, and Zinc in the digestive tract making the difficult/impossible to absorb.
sweet potatoes
Contain a tryspin inhibitor which will actually inhibit the digestion of protein especially if they are uncooked. Cooking will kill most of this though but not all.
white potatoes
same thing as sweet potatoes but to a stronger degree especially in the skin
white rice
has the grain removed but still contains many antinutrients
Phytic acid is a substance found in cereal grains, nuts, seeds, and legumes that prevents premature germination and stores nutrients for plant growth.1,2,3,43,44 Research has shown that it also reduces the absorption of the important minerals calcium, magnesium, iron, and zinc when consumed by humans.4,5,6,7,43,45,46 Phytic acid also has potential to reduce the digestibility of protein.17 This doesn’t only apply to the minerals and protein in the food containing the phytic acid, but also the food that you eat with it.
