For people who are healthy, a healthy diet is not complicated and contains mostly fruits, vegetables, and whole grains, and includes little to no processed food and sweetened beverages. The requirements for a healthy diet can be met from a variety of plant-based and animal-based foods, although a non-animal source of vitamin B12 is needed for those following a vegan diet.

Think smaller portions. Serving sizes have ballooned recently. When dining out, choose a starter instead of an entree, split a dish with a friend, and don’t order supersized anything. At home, visual cues can help with portion sizes. Your serving of meat, fish, or chicken should be the size of a deck of cards and half a cup of mashed potato, rice, or pasta is about the size of a traditional light bulb. By serving your meals on smaller plates or in bowls, you can trick your brain into thinking it’s a larger portion. If you don’t feel satisfied at the end of a meal, add more leafy greens or round off the meal with fruit.

These support bone health and have other possible benefits. Dairy products are the best sources of calcium, but you can also get it from fortified foods as well as canned salmon, sardines, dark leafy greens, and most tofu. If you can’t get the recommended 1,000 to 1,200 milligrams a day from food, take a calcium supplement. It’s hard to consume enough vitamin D from foods (the RDA is 600 to 800 IU a day, though other experts advise more). Thus, many people—especially those who are over 60, live at northern latitudes, or have darker skin—should consider taking a supplement.
