Document Summary
Nissi lives in a small village in india where her family are subsistence farmers (grow their own food). She has been feeling tired lately and noticed a lump at the front of her neck. Again, absorption of minerals with the same charge may depend on the relative amounts in a meal. Items with the same charge may interfere with the absorption. Dietary components may enhance or inhibit absorption; bioavailability is key here due to the small amounts present in the diet. Amounts of these minerals in foods may depend on where the food is grown, this has implications for those who eat only food produced locally. We have this idea of bioavailability being even more important because of the fact we have smaller amounts that are being required. Cooking the greens can sometimes make the food more bioavailable. Iron is absorbed from the diet in the heme (animal source) or nonheme (plant sources) form.
