Red grapes are rich in polyphenols, which are antioxidant plant compounds, explains Ruani.

Red grapes are particularly rich in anthocyanins, which have been shown to benefit brain health, and resveratrol, which has anti-inflammatory, anti-aging effects.

Red grape skins and seeds are also rich in antioxidants, including catechin and epicatechin, which help reduce oxidative stress in the body.

Grapes are rich in fiber, which helps reduce bad cholesterol levels. This is because the soluble fiber in grapes can delay or reduce the absorption of cholesterol into the blood.

Research published in the academic journal Food and Function journal in 2015 found that people with high cholesterol who ate three cups of red grapes a day for eight weeks reduced their total cholesterol and bad cholesterol levels, according to the Express .

Red grapes may be a great option not only to help lower cholesterol and blood sugar levels, but also to reduce cholesterol-related cardiovascular diseases, especially in people with hyperlipidemia, the researchers said.

Another study by the University of California (USA), published in the scientific journal Nutrients , also discovered the cardiovascular health benefits of grapes with reduced cholesterol.

Results showed that after 4 weeks of grape consumption, the number of a type of probiotic that promotes glucose and lipid metabolism increased.

Additionally, total cholesterol decreased by 6.1% and bad cholesterol decreased by 5.9%.

The authors also found that bile acids involved in cholesterol metabolism were reduced by 40.9%, according to the Daily Mail.

According to the research team, these findings suggest a promising new role for grapes in cardiovascular health.
