MEASURED NUTRIENT ROLES
Top nutrients that support the body
For 100 g, the strongest Daily Value contributions among nutrients available in this record are Phosphorus (1.5% DV), Calcium (1.1% DV) and Zinc (0.6% DV). The cards explain the normal roles of those nutrients, not a treatment effect of the food.
Phosphorus: bones and cellular energy
This amount provides 19 mg. Phosphorus helps form bones and teeth and is involved in energy production and cell membranes. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceCalcium: bones, muscles and nerves
This amount provides 14 mg. Calcium helps form bones and teeth and supports normal muscle, nerve and blood-vessel function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceZinc: immune function and repair
This amount provides 0.07 mg. Zinc supports immune function, DNA and protein synthesis, wound healing, growth and the sense of taste. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referencePotassium: fluid balance and muscles
This amount provides 19 mg. Potassium supports normal cell function, fluid balance, nerve transmission and muscle contraction. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceMagnesium: energy, muscles and nerves
This amount provides 1.6 mg. Magnesium supports enzyme reactions, energy production, protein synthesis, and normal muscle and nerve function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceIron: oxygen transport
This amount provides 0.03 mg. Iron is needed for hemoglobin and myoglobin, which carry oxygen, and supports growth and neurological development. This describes the nutrient’s normal role, not disease prevention or treatment.

Contributes Phosphorus
This amount provides 19 mg. Phosphorus helps form bones and teeth and is involved in energy production and cell membranes. This is a measured nutrient contribution, not proof that the food prevents or treats disease.
