For some obese people over the age of 40, problems such as high blood pressure and insulin resistance, known as metabolic syndrome, can lead to heart disease and type 2 diabetes.
Although metabolic syndrome is not clearly defined, it usually includes excess waist fat, high triglycerides, high blood pressure, decreased glucose tolerance, and increased levels of c-reactive protein.
In recent decades, the effects of metabolic syndrome have become apparent, especially in western countries. People with metabolic syndrome have a higher risk of cardiovascular disease and type 2 diabetes.
A laboratory study from Michigan state university has found that eating grapes may be the solution to metabolic syndrome. The study was published in the American journal of biomedical science. Researchers say eating grapes can lower blood pressure, boost heart function and reduce the risk of heart disease and metabolic syndrome. But these conclusions are based on experiments in laboratory rats.
A diet rich in grapes can help lower blood pressure
In the study, rats of different breeds were overweight, and they used red, green and black grape powder as part of a high-fat diet. The scientists then compared the behaviour of the rats with those of other non-grape eaters. Three months later, the rats that ate the powder had lower blood pressure, and had lower heart function and inflammation than the other rats. In addition, the levels of triglycerides and glucose tolerance were significantly increased in rats in the grape group.
The study confirms other researchers’ arguments that eating grapes protects the heart against high blood pressure.
The antioxidants in grapes are key to boosting heart function
The reason why grape rich diet can help rats resist the adverse effects of high-fat and high-sugar diet is related to the large amount of antioxidant phytonutrients in grapes. However, no human studies have been conducted on this subject. However, available data have confirmed that antioxidants in grapes do have significant benefits in reducing the risk of cardiovascular disease and diabetes.
Eat grapes in moderation
To protect your heart, eating grapes can also help. A study in the United States showed that after 18 weeks of eating grapes, rats’ blood pressure and heart function improved.
But doctors warn that grapes should be eaten in moderation because too much can lower blood pressure and raise blood sugar.
Eating too many grapes is good for blood vessels and heart health, but the sugar in grapes is very high, so be careful not to eat too many grapes, otherwise it will cause blood sugar to rise.
Grape seeds and skins are equally important
Grape seeds and skins also need to be eaten, and they have many health benefits. In the United States, grape seed essence is very popular. The benefits of grape seeds and skins are as follows:
1. Promote cardiovascular health
2. Enhance immunity
3. Improve eye health
4. It has anti-inflammatory effect
5. Prevent premature aging of skin
6. Maintain healthy capillary and vascular function.
7. Eliminate free radicals in cells to prevent aging.
8. Protect the central nervous system of the brain by crossing the blood-brain barrier.
Improve blood circulation and reduce inflammation.
10. Improve immunity and reduce allergy.
11. Free radicals can wreak havoc on your health. In fact, environmental pollution, smoking, diet and metabolism all produce free radicals, leading to a variety of degenerative diseases. One of them
12. The best way to reduce and neutralize the effects of free radicals on the body is to increase the intake of various antioxidants.
