Tomato
What it is
Tomatoes are eaten fresh and in many prepared foods. This reference is the USDA year-round average for red, ripe, raw tomatoes, not tomato paste, sauce, juice or an extract.
What it does
Per 100 g raw, the record contains 13.7 mg of vitamin C, 237 mg of potassium and 1.2 g of fiber. Vitamin C has a normal role in collagen production.
Research context and ingredient forms
Concentrating tomatoes into paste changes the amount of tomato solids per unit weight. A lycopene supplement also has a different scope from the whole raw food; the presence of a compound alone does not establish a clinical benefit.
Using this information
Choose a profile matching the form you eat. For jarred sauce, use its label to include added sodium, oil and other ingredients rather than multiplying the raw-tomato table.
