MEASURED NUTRIENT ROLES
Top nutrients that support the body
For 100 g, the strongest Daily Value contributions among nutrients available in this record are Manganese (40.9% DV), Copper (24.4% DV) and Niacin (B3) (20.4% DV). The cards explain the normal roles of those nutrients, not a treatment effect of the food.
Manganese: metabolism and antioxidant enzymes
This amount provides 0.94 mg. Manganese supports metabolism, bone formation and antioxidant enzyme systems. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceCopper: iron metabolism and nerves
This amount provides 0.22 mg. Copper supports energy production, connective tissue, iron metabolism, and normal nervous and immune function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceNiacin (B3): energy and cell function
This amount provides 3.26 mg. Niacin helps enzymes convert food into energy and supports normal cell function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceVitamin C: collagen and antioxidant function
This amount provides 17.8 mg. Vitamin C acts as an antioxidant and supports collagen production, immune function and absorption of nonheme iron. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceVitamin A: vision and immune function
This amount provides 168 µg. Vitamin A supports normal vision, immune function, growth and cell development. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceRiboflavin (B2): energy and cell growth
This amount provides 0.13 mg. Riboflavin helps convert food into energy and supports cell growth, development and function. This describes the nutrient’s normal role, not disease prevention or treatment.

Food-specific benefits & evidence
High in Manganese
This amount provides 0.94 mg. Manganese supports metabolism, bone formation and antioxidant enzyme systems. This is a measured nutrient contribution, not proof that the food prevents or treats disease.
