Red wine, in moderation,
has long been thought of as heart healthy.
The alcohol and certain substances in red wine called antioxidants may help prevent heart disease by increasing levels of “good” cholesterol and protecting against artery damage.
Antioxidants in red wine called polyphenols help protect the lining of blood vessels in your heart. These antioxidants come in two main forms: flavonoids and nonflavonoids.
- Flavonoids. These antioxidants are found in a variety of foods, including oranges, grape juice, apples, onions, tea and cocoa. Other types of alcohol, such as white wine and beer, contain small amounts, too, but red wine has higher levels.
Flavonoids, exhibit antioxidant properties helping prevent blood clots and plaques formation in arteries.
- Nonflavonoids. These antioxidants found in red wine have recently been of particular interest because they appear to help prevent arteries from becoming clogged with fatty blockages.
However, these studies mostly involved mice — not humans.
Resveratrol in red wine might be a key ingredient.
Resveratrol, found in grapes skins and seeds, increases HDL cholesterol and prevents blood clotting as well.
What is HDL?
HDL is the GOOD cholesterol that carries the LDL away from the artery walls to the liver for removal from the body.
