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.

Hypertension

Human clinical evidence · DASH and sodium-reduction trials support lowering blood pressure through dietary patterns. A potassium-containing food is not itself a validated hypertension treatment.

Portions, sodium, medicines and kidney function matter. Follow individualized care; this is not an instruction to increase potassium or stop medication.

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.
