Nutrition & Diet

Here you will find explainers on eating patterns, protein, fiber, vitamins, minerals and how to read food and supplement labels.

We base our nutrition guides on public health sources and published research. When a supplement comes up, we look at the dose, the evidence and possible side effects.

Talk to your doctor or a dietitian before big diet changes if you have diabetes, kidney disease, are pregnant, or take medication.

Can you get the nutrients you need from food instead of supplements?

Most healthy adults can get the nutrients they need from a varied diet with vegetables, fruits, whole grains, protein foods, and dairy or fortified alternatives. Some groups may need a supplement, such as people who are pregnant, older adults, and people on restricted diets. A doctor or dietitian can tell you if you have a real gap.
