Healthy Eating

Fill up on colorful fruits and vegetables 

Fruits and vegetables are the foundation of a healthy diet. They are low in calories and nutrient dense, which means they are packed with vitamins, minerals, antioxidants, and fiber.
Try to eat a rainbow of fruits and vegetables every day and with every meal—the brighter the better. Colorful, deeply colored fruits and vegetables contain higher concentrations of vitamins, minerals, and antioxidants—and 
different colors provide different benefits, so eat a variety. Aim for a minimum of five portions each day.
Some great choices include:
  • Greens. Branch out beyond bright and dark green lettuce. Kale, mustard greens, broccoli, and Chinese cabbage are just a few of the options—all packed with calcium, magnesium, iron, potassium, zinc, and vitamins A, C, E, and K.
  • Sweet vegetables. Naturally sweet vegetables—such as corn, carrots, beets, sweet potatoes, yams, onions, and squash—add healthy sweetness to your meals and reduce your cravings for other sweets.
  • Fruit. Fruit is a tasty, satisfying way to fill up on fiber, vitamins, and antioxidants. Berries are cancer-fighting, apples provide fiber, oranges and mangos offer vitamin C, and so on.

The importance of getting vitamins from food—not pills

The antioxidants and other nutrients in fruits and vegetables help protect against certain types of cancer and other diseases. And while advertisements abound for supplements promising to deliver the nutritional benefits of fruits and vegetables in pill or powder form, research suggests that it’s just not the same.
A daily regimen of nutritional supplements is not going to have the same impact of eating right. That’s because the benefits of fruits and vegetables don’t come from a single vitamin or an isolated antioxidant.
The health benefits of fruits and vegetables come from numerous vitamins, minerals, and phytochemicals working together synergistically. They can’t be broken down into the sum of their parts or replicated in pill form.

Eat more healthy carbs and whole grains

Choose healthy carbohydrates and fiber sources, especially whole grains, for long lasting energy. In addition to being delicious and satisfying, whole grains are rich in phytochemicals and antioxidants, which help to protect against coronary heart disease, certain cancers, and diabetes. Studies have shown people who eat more whole grains tend to have a healthier heart.

A quick definition of healthy carbs and unhealthy carbs

Healthy carbs (sometimes known as good carbs) include whole grains, beans, fruits, and vegetables. Healthy carbs are digested slowly, helping you feel full longer and keeping blood sugar and insulin levels stable.
Unhealthy carbs (or bad carbs) are foods such as white flour, refined sugar, and white rice that have been stripped of all bran, fiber, and nutrients. Unhealthy carbs digest quickly and cause spikes in blood sugar levels and energy.

Tips for eating more healthy carbs

  • Include a variety of whole grains in your healthy diet, including whole wheat, brown rice, millet, quinoa, and barley. Experiment with different grains to find your favorites.

  • Make sure you're really getting whole grains. Be aware that the words stone-ground, multi-grain, 100% wheat, or bran can be deceptive. Look for the words “whole grain” or “100% whole wheat” at the beginning of the ingredient list. In the U.S., Canada, and some other countries, check for the Whole Grain Stamps that distinguish between partial whole grain and 100% whole grain.
  • Try mixing grains as a first step to switching to whole grains. If whole grains like brown rice and whole wheat pasta don’t sound good at first, start by mixing what you normally use with the whole grains. You can gradually increase the whole grain to 100%.
Avoid: Refined foods such as breads, pastas, and breakfast cereals that are not whole grain.

Enjoy healthy fats & avoid unhealthy fats 

Good sources of healthy fat are needed to nourish your brain, heart, and cells, as well as your hair, skin, and nails.  Foods rich in certain omega-3 fats called EPA and DHA are particularly important and can reduce cardiovascular disease, improve your mood, and help prevent dementia.

Add to your healthy diet:

  • Monounsaturated fats, from plant oils like canola oil, peanut oil, and olive oil, as well as avocados, nuts (like almonds, hazelnuts, and pecans), and seeds (such as pumpkin, sesame).
  • Polyunsaturated fats, including Omega-3 and Omega-6 fatty acids, found in fatty fish such as salmon, herring, mackerel, anchovies, sardines, and some cold water fish oil supplements. Other sources of polyunsaturated fats are unheated sunflower, corn, soybean, flaxseed oils, and walnuts.

Reduce or eliminate from your diet:

  • Saturated fats, found primarily in animal sources including red meat and whole milk dairy products.
  • Trans fats, found in vegetable shortenings, some margarines, crackers, candies, cookies, snack foods, fried foods, baked goods, and other processed foods made with partially hydrogenated vegetable oils.
