Have you ever heard or read anywhere that it is important to “eat a rainbow” of foods? It might sound silly, but there’s a good science behind the concept of eating a wide variety of different colored fruits and vegetables. According to research reported by North Dakota State University (NDSU), people who eat a variety of different of fruits and veggies may have reduced risk of certain diseases, such as stroke, diabetes, and cancer. Plants derive their colors from the phytonutrients they contain. Phytonutrients, also known as photochemicals are natural chemicals or compounds produced by plants. They keep plants healthy, protecting them from insects and the sun.

For example, plant based foods such as fruits, vegetables, legumes, grains, nuts and seeds, herbs and spices etc. have different colors. The colors identify certain nutrients, that can be seen as tidbits of information about the plant and the nutrients it may contain. Hence, the color of your food can tell a lot about its nutritional value. Read on, and find out some of these colors and what they contain.

Red

This is strongest color in the color spectrum, red foods are loaded with the phytonutrient lycopene which gives them their vibrant red color. Lycopene also helps battle cancer, heart disease and has been known to help in cases of cataracts and asthma. Tomatoes and watermelons contain the highest levels of lycopene. Red beets are a good source of vitamin C for fighting the common cold, and betaine for cardiovascular health. Beets have zero fats, are low in calories, and are a great energy booster because they are high in carbohydrates and a natural source of sugar.
