Gabe was experiencing fatigue, despite sleeping eight hours per night. He went to the doctor and was diagnosed with iron-deficiency anemia. The doctor recommended he eat iron-fortified breakfast cereals. Which food would be the best accompaniment for his iron-fortified breakfast cereal and why? -Having an egg with the iron-fortified breakfast cereal because biotin in the egg protein increases iron absorption -Having a cup of orange juice or an orange with the iron-fortified breakfast cereal because vitamin C in the orange increases iron absorption -Having a cup of milk on his iron-fortified breakfast cereal because vitamin D in the milk increases iron absorption -Having a banana on his iron-fortified breakfast cereal because potassium in the banana increases iron absorption -Vitamin C enhances iron absorption by keeping iron in its most absorbable form, especially as the mineral travels through the small intestine's alkaline environment. Increasing intake of vitamin C-rich foods is beneficial for those with poor iron stores.
Having a cup of orange juice or an orange with the iron-fortified breakfast cereal because vitamin C in the orange increases iron absorption

Lino recently saw a "high-potency" mineral supplement being advertised on a late-night infomercial. He compared the amount of minerals in the supplement with the Daily Values for the minerals and determined that the supplement contained megadoses of minerals. Why can taking megadoses of individual mineral supplements be potentially harmful? -Taking megadoses of individual mineral supplements can greatly diminish the absorption and metabolism of other minerals. -Taking megadoses of individual mineral supplements can increase blood pressure, increasing risk for cardiovascular disease and stroke. -Taking megadoses of individual mineral supplements supplies unneeded extra calories in the body that can contribute to weight gain and associated chronic disease risks. -There is nothing harmful about taking megadoses of individual mineral supplements: minerals are water soluble so they are excreted from the body in urine if consumed in excess. -Taking megadoses of an individual mineral supplement can greatly diminish the absorption and metabolism of other minerals
Taking megadoses of individual mineral supplements can greatly diminish the absorption and metabolism of other minerals.
