What are Plant Pigments

Plant pigments are colorful, chemical compounds present in plants that are responsible for the colors of plants. Not only do they reflect certain wavelengths of visible light to give them color, but they also absorb certain wavelengths of light for photosynthesis. There are many different types of plant pigments, but the most common are chlorophylls, which give plants their green color and convert light energy into chemical energy. Carotenoids are usually yellow, red or orange and help fuel photosynthesis. Carotenoids are great antioxidants and promote healthy eyesight. Flavonoids can be red or blue or even white or pale yellow – there are many different pigments from anthocyanins (blue) to betalains (yellow or red). Some are water-soluble and some are not. Pigments play many different roles, from attracting our visual attention and the attention of pollinators, to providing us with vitamins and nutrients.

Researches are Convinced that Juice Prevents Blockages in the Arteries

Recently, researchers conducted an experiment that involved hamsters that were given water and hamsters who received juice in an amount that was comparable to four glasses daily for an individual who weighed approximately one hundred and fifty pounds. While other hamsters were apples or grapes with human equivalents of three apples a day or three bunches of grapes per day. Researchers studied how the fruits affected the risk of atherosclerosis in hamsters. Atherosclerosis has become a major health concern for humans in recent years due to unhealthy diet and lifestyle changes. Consequently, the results grapes and apples may beneficial in preventing atherosclerosis among humans as well.

Hamsters who received either fruit or juice had lower cholesterol, less aortic fat build-up, and less oxidative stress. The results of this study seem to suggest that there is a direct correlation between the amount of phenol contained in fruit and its antioxidant benefits.

The study revealed that apples and grapes had about the same phenol content while purple grape juice had more than double the phenol content of apples or grapes.

In fact, purple grape juice had the strongest antioxidant effect, followed by purple grapes, apple juice, and apples.

Antioxidants have long been considered to good for your health, however these findings seem to indicate that phenols and other antioxidants contained in fruit such as vitamin C and carotenoids may greatly affect an individual’s risk of heart attack and stroke.
