1. Boosts Heart Health
Active compounds in red wine, including polyphenols, resveratrol and quercetin, have proved to have cardioprotective properties.
Numerous cross-sectional, observational and controlled studies show that drinking moderate amounts of red wine has beneficial effects on many different aspects related cardiovascular disease.
Research shows that the antioxidant nutrients in red wine can slow down the progression of atherosclerosis, a type of arteriosclerosis that occurs when there’s buildup of fats, cholesterol and plaque in the artery walls.
There’s also plenty of evidence supporting the beneficial role of resveratrol, which protects the heart cells from tissue damage after a stroke, inhibits platelet buildup, and decreases triglyceride and cholesterol accumulation.
Resveratrol has also been shown to relax the coronary arteries, making it at least partly responsible for the red wine benefits that are associated with cardiovascular disease.
2. Improves Cholesterol
According to a study published in the European Journal of Clinical Nutrition, wine consumption was associated with a significant increase in HDL cholesterol, with participants seeing their levels improve by 11 percent to 16 percent.
Another study, conducted at Curtin University in Australia, found that regular consumption of red wine reduced the risk of developing cardiovascular disease by lowering LDL cholesterol levels in postmenopausal women by 8 percent and increased HDL cholesterol levels by 17 percent.
3. Fights Free Radical Damage
The accumulation of free radicals plays a major role in the development of chronic and degenerative diseases, including cancer, autoimmune diseases, rheumatoid arthritis, cardiovascular disease and neurodegenerative diseases.
The antioxidants in red wine help counteract oxidative stress by acting as free radical scavengers that prevent and repair damage caused by oxidation.
Antioxidants enhance the body’s immune defenses and lower the risk of developing a number of serious health conditions.
Because of its ability to fight free radical damage, resveratrol found in red wine has the ability to block the multistep process of carcinogenesis, including the various stages of tumor initiation, promotion and progression.
Resveratrol is involved in the downregulation of the body’s inflammatory responses.
4. Helps Manage Diabetes
Both red and white wines were tested to determine how well they could inhibit the activity of an enzyme that’s responsible for triggering the absorption of glucose.
Researchers found that red wine was the clear winner, inhibiting the enzymes by nearly 100 percent, while values for white wine were around 20 percent.
The efficacy of red wine was so significant because it contains roughly 10 times more polyphenolics (a type of antioxidants) than white wine.
In addition to these findings, the study found another red wine benefit, which is that it had no effect on a pancreatic enzyme that breaks down starch and is needed by patients to avoid the side effects of blood sugar medications.
5. Fights Obesity and Weight Gain
A study conducted at Purdue University found that red wine may help to fight obesity.
This is due to a compound found in grapes and other fruits (like blueberries and passionfruit) called piceatannol, which has a similar chemical structure to resveratrol.
According to researchers, piceatannol blocks an immature fat cell’s ability to develop and grow.
It’s also been found to alter the timing of gene expressions, gene functions and insulin functions during the fat cell’s metabolic process.
When piceatannol is present, there’s a complete inhibition of adipogenesis, the process of cell development.
Piceatannol is so effective at fighting obesity and weight gain because it’s able to destroy fat cells early in the process of cell development, thereby preventing fat cell accumulation and, later on, body mass gain.
It does this by binding to insulin receptors found in fat cells and blocking insulin’s ability to control cell cycles.
It also blocks insulin’s activity to activate genes that are important in the later stages of fat formation.
6. May Help Prevent Alzheimers’s Disease
Research indicates that people who eat a Mediterranean diet, consisting of red wine, vegetables, legumes, fruits, fish and olive oil, have a 28 percent lower risk of developing mild cognitive impairment and a 48 percent lower risk of progressing from mild cognitive impairment to Alzheimer’s disease.
There’s even more research on the red wine specifically as a preventive measure and natural treatment for Alzheimer’s.
According to research published in Frontiers in Aging and Neuroscience, resveratrol may control the main features of Alzheimer’s disease and slow dementia progression.
This is due to resveratrol’s ability to reduce oxidative stress and inflammation, and work as a neuroprotectant.
