Eat the Rainbow
In this article we will discuss the importance of eating a colorful diet. The term “eat the Rainbow” is a simple and easy way to remember to fill your plate with a variety of colors! Fruits and vegetables are rich in vitamins, minerals, fiber, antioxidants and phytochemicals. Often why these foods are called “super foods” which is really just a fancy way of saying these foods are good for you. Incorporating more fruits and vegetables not only can increase your nutrient intake, but it can also help with the regulation of blood pressure, blood sugar, cholesterol, GI functions and body weight. Not to mention that they are very low in calories and have no fat. Who doesn’t love that?
Vitamins and Minerals.
Some of the vitamins and minerals found in fruits and vegetables aid in the function of blood, vision, nervous system, nail growth and even healing that scrape on your knee. Do you remember your mom telling you as a kid to eat your carrots because they help you see at night? Well she wasn’t wrong, vitamin A or carotene is found in yellow-orange pigmented fruits and vegetables. A deficiency in this vitamin can cause nighttime blindness.
Vitamin E and K can affect your bodies ability to clot your blood. If you are on a blood thinner make sure to talk to your doctor before you pretend to be Popeye the Sailor Man. These vitamins can be found in kale, spinach, broccoli and healthy oils like olive and sunflower.
As for vitamin C, the history dates all the way back to the 1490s when Portuguese sailors presented with bleeding gums and poor wound healing from a lack of vitamin C! Once they determined this was from a vitamin C deficiency, sailors would travel loads of lemons and limes on board.
Calcium and Iron aid in many processes in the body, including muscular functions and even can help prevent anemia. Believe it or not dark leafy greens are extremely rich in both iron and calcium. So remember to load up on those dark greens the next time you are eating dinner.
What are Antioxidants and Phytochemicals?
Antioxidants are found in fruits and vegetables help prevent cellular damage from free radicals. Free radicals are unstable molecules that can cause cellular damage leading to aging and chronic disease.
