Safety first with food

Allergy: tree nut, peanut and sesame are different allergies. Each food page lists what its sources say.
Some foods interact with medicines, for example vitamin K in leafy greens with warfarin, and grapefruit with several medicines.
Kidney conditions can limit potassium, phosphorus and oxalate. Ask a clinician before changing your diet.
A whole food, a juice, a powder and a capsule are different things. Studies of one do not automatically apply to another.

Frequently asked questions

Where did the food pages go?

Nothing moved. Fruits, Vegetables, Nuts & Seeds, Spices and Functional Foods keep their addresses (for example /fruits). They now sit together under Food & Nutrition instead of Natural Remedies, joined by Whole Grains, Legumes, Fermented Foods, Oils & Fats, Beverages and Seaweed & Algae.

Is a food the same as a supplement?

No. A whole food, a juice, a powder and a capsule are different products, and studies of one do not automatically apply to another. Vitamins & Supplements is a separate department, linked from here.

Where do the nutrient amounts come from?

From USDA measurements of the food, shown on each food's guide. Research findings are kept apart from the measured amounts.
