MEASURED NUTRIENT ROLES
Top nutrients that support the body
For 100 g, the strongest Daily Value contributions among nutrients available in this record are Selenium (247% DV), Copper (149% DV) and Magnesium (88.6% DV). The cards explain the normal roles of those nutrients, not a treatment effect of the food.
Selenium: thyroid and antioxidant defense
This amount provides 136 µg. Selenium supports thyroid hormone metabolism, DNA synthesis and protection from oxidative damage. 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 1.34 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 referenceMagnesium: energy, muscles and nerves
This amount provides 372 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 referenceDietary fiber: digestion and fullness
This amount provides 23.1 g. Dietary fiber supports digestion, adds bulk to stool, and can help with fullness. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referenceThiamin (B1): energy and cell function
This amount provides 0.54 mg. Thiamin helps turn food into energy and supports normal cell growth and function. This describes the nutrient’s normal role, not disease prevention or treatment.
Read the NIH/FDA nutrient referencePhosphorus: bones and cellular energy
This amount provides 556 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.

Food-specific benefits & evidence
High in Selenium
This amount provides 136 µg. Selenium supports thyroid hormone metabolism, DNA synthesis and protection from oxidative damage. This is a measured nutrient contribution, not proof that the food prevents or treats disease.
