This transition is a key factor in the mutation of genes, especially those that regulated dietary iron absorption. Iron, which makes up 70% of red blood cell composition, is a critical micronutrient for effective thermoregulation in the body. [55] Iron deficiency will lead to a drop in the core temperature.
“Calcium inhibits the absorption of nonheme iron (the type of iron found in supplements and plant-based sources) by competing for absorption in the intestines,” says Carla Hernandez, RDN, a ...
White beans. There’s a reason beans are a go-to for plant-based eaters. One half-cup of white beans offers nearly 3.5 mg of iron, the USDA says, along with 8.7 grams (g) of protein and 5.6 g of ...
