THE MODERN LIVING FOUNTAIN OF YOUTH · FOOD KNOWLEDGE
A food is never
just one thing.
Find a food. Explore a body system. Investigate a health question—and the world behind the meal.
One connected path: red foods → heart & circulation → tomatoes
RED FOODS → HEART & CIRCULATION → TOMATOES → HEALTH EVIDENCE → RELATED RECIPES
This is one reviewed discovery path. Tomato nutrient composition supports the physiology links; red color does not assign foods to the heart or establish disease prevention. Start with any food, system or health question.
29 exact preparations have reviewed body-system and health-topic connections. These are research paths, not foods prescribed for a condition. Color selection is optional.
Immune Function
Vitamin A, zinc, vitamin B6 and vitamin E participate in normal immune function. This does not mean that a food boosts immunity or prevents infection.
Nutrients, functions & sources
Vitamin A: Vitamin A supports normal vision, immune function, reproduction, growth and development. The body converts some plant carotenoids into vitamin A. NIH ODS · Vitamin A and Carotenoids ↗
Zinc: Zinc supports immune function and is involved in making proteins and DNA, wound healing, and taste. NIH ODS · Zinc ↗
Vitamin B6: Vitamin B6 is involved in many enzyme reactions, especially protein metabolism, and contributes to brain development and immune function. NIH ODS · Vitamin B6 ↗
Vitamin E: Vitamin E acts as an antioxidant and participates in immune function and cell communication. NIH ODS · Vitamin E ↗

What these numbers mean.
A food profile is a particular preparation in USDA’s SR Legacy reference dataset. A nutrient record is one reported food–nutrient amount, including reported zeros. These are not 142,336 health claims or clinical studies.
Source: April 2018 final SR Legacy. Imported October 15, 2026. Values are reference composition per 100 g edible portion, with available USDA household portions. Fresh, dried, cooked, salted and fortified forms remain distinct; missing values remain missing.
Plant-focused groups include herbs and spices, fruit, vegetables, nuts and seeds, legumes, grains and pasta. Some prepared products contain other ingredients. Color tags are an editorial guide to food families and appearance; actual cultivars and preparations vary.
