Question

Show the interactions of any 5 pairs of nutrients, explain the science behind the interactions For example, Vitamin E and Vitamin C- when Vitamin E gives up an electron to stop free radical reaction, Vitamin C helps Vitamin E to regain its lost electron.

Answer 1

Vitamin D and calcium

Like most nutrients, calcium is absorbed primarily in the small intestine. If large quantities are present, much of the bone-strengthening mineral diffuses across the inner lining of the intestine on its own. But in smaller amounts, the mineral gets absorbed with active assistance from vitamin D and several of its metabolic offspring

The principal function of vitamin D in calcium homeostasis is to increase calcium absorption from the intestine. Calcium is absorbed by both an active transcellular pathway, which is energy dependent, and by a passive paracellular pathway through tight junctions. 1,25Dihydroxyvitamin D3 (1,25(OH)2D3) the hormonally active form of vitamin D, through its genomic actions, is the major stimulator of active intestinal calcium absorption which involves calcium influx, translocation of calcium through the interior of the enterocyte and basolateral extrusion of calcium by the intestinal plasma membrane pump.

Vitamin c and folic acid

Vitamin C, also known as ascorbic acid, is a water-soluble vitamin thought to increase the absorption of nonheme iron. Vitamin C acts as a reducing agent to facilitate iron absorption from the GI tract and to enable its mobilization from storage.

Vitamin B12 and folate

Vitamin B12 and folate form one of nutrition's more estimable couples. They work together to support some of the most fundamental processes of cell division and replication. They also metabolize homocysteine together. And folate, which is itself one of the eight B vitamins, depends on B12 to be absorbed, stored, and metabolized.

Vitamin D and calcium

Vitamin D is well known as a hormone involved in mineral metabolism and bone growth. Its most dramatic effect is to facilitate intestinal absorption of calcium, although it also stimulates absorption of phosphate and magnesium ions. In the absence of vitamin D, dietary calcium is not absorbed at all efficiently.1,25(OH)2D increases calcium absorption by binding to the vitamin D receptor in the intestine.

Vitamin D and Omega-3s

Vitamin D is a fat soluble vitamin, meaning that it needs fat to be absorbed. Omega-3 contain fatty acids so the fat in it can help the body absorb vitamin D.The three main omega-3 fatty acids are alpha-linolenic acid (ALA), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA).
