Continuing on with yet another fruit, today we are highlighting grapes. Yes the variety little juicy berries that come in red, purple, and green. Grapes are known for their polyphenol concentration. Of the polyphenols special attention is paid to flavonoids, phenolic acids, and resveratrol. Most flavonoids can be found in the skins, stems, and seeds. They’re responsible for the vibrant purple color, the darker the fruit the higher the flavonoid content. Some of the flavonoids (which includes quercitin) help decrease the risk of heart disease. How does it do this?
- reduce platelet clumping and harmful blood clots
- protect LDL free radical damage=clot
Now onto the wonderful resveratrol. This polyphenol can inhibit production of angiotension II (hormone secreted in response to increased blood pressure and heart failure). This has a negative effect by signalling cardio fibroblasts (heart muscle cells that secrete collagen). The excessive collagen causes the heart to stiffen, which decreases the ability of the heart to pump blood efficiently. Studies have also shown that it may improve blood flow by 30%, which decrease the risk of stroke. For more on our weight loss programs check out bodychange.net
