- Which of the following statements regarding dietary nutrients is FALSE? Macronutrients provide cells with energy whereas micronutrients provide protein cofactors. Water soluble vitamins can be stored long-term. Enriched foods contain synthetic vitamins to replace natural vitamins lost during processing. Fortified foods contain vitamins and minerals not originally found in the foods. The majority of B vitamins must be converted to their active form in the body.arrow_forwardSymptoms of deficiencies Drag and drop each symptom of deficiency to the correct type of substance.

- Which statements about absorption of vitamins or minerals are true? Select all that apply. Micronutrients may be in competition for absorption with each other. Vitamins and minerals are efficiently absorbed by the body between 85% and 99% of what is consumed. To be useful for cellular function, vitamins must remain in their original chemical structure. Calcium found in plant sources is more readily absorbed than from animal sources. Absorption of some vitamins and minerals can be influenced by what sort of foods are consumed within the same meal.
