The benefit of a diet rich in fruits and vegetables is so well-documented it hardly bears repeating. Eating the right natural foods wards off disease, enables you to live longer, makes you look better, and gives you additional energy. Yet most people fail to eat enough fruits and vegetables but consume large quantities of unnecessary foods. This problem influences more than just your physical health. A study of 80,000+ people suggests that total intake of fruits and vegetables is a robust predictor of overall happiness.
Every additional daily serving of fruits or vegetables, all the way up to seven servings, continues to improve well-being. However, we do not have a quick way to determine what foods are the healthiest. We receive conflicting advice from different sources. Then we face countless choices every time we go to a grocery store or place an order at a restaurant. An efficient mental shortcut is to judge a fruit or vegetable by the color of its skin. Generally speaking, produce with dark and vibrant colors is your best bet. Green means go.
Broccoli, spinach, kale, bok choy, celery, cucumbers, peppers, zucchini, and other dark leafy greens are net positives for your health. Also look to red or blue fruits and vegetables as good nutritional sources. Apples, peppers, raspberries, strawberries, tomatoes, and almost any fruit or vegetable with vibrant skin tone makes for a better choice. The next time you are in a grocery store, start by shopping in sections with dark-colored fruits and vegetables.
