The color and shape of the grapes vary according to the variety. Not to mention red, green, and purple grapes, seedless grapes, grape jelly, grape jelly and juice, raisins, small seedless raisins like fusaguri and sultana, and wine.
At most 8,000 years ago, people first grew grapevines in what is now the Middle East.
Today, 72 million tons of grapes are grown every year around the world, most of them for wine production. Every year 7.2 trillion gallons of wine are produced. Grapes are also a popular snack.
The nutrients in grapes have many health benefits and are associated with the prevention of cancer, heart disease, high blood pressure, and constipation.
What was confirmed about the grapes
Grapes are an excellent source of fiber, potassium, various vitamins, and other minerals.
Grapes are suitable for people with diabetes as long as they are indicated in the weight loss plan.
Benefits of consuming grapes
A diet rich in fruits and vegetables is also associated with a reduced risk of various conditions, such as heart disease, diabetes, cancer, and obesity. The antioxidants and other nutrients in grapes appear to be particularly healthy, but more research is needed to confirm their benefits.
This is how the nutrients in grapes can improve your health.
Grapes contain powerful antioxidants called polyphenols. It is believed to have anti-inflammatory and antioxidant properties. One of them is resveratrol, which is found in the skin of red grapes.
Laboratory studies suggest that resveratrol may slow or prevent further growth of cancer of the lymph, liver, stomach, breast, colon, skin, and leukemia.
Resveratrol is also found in red wine. Few studies have investigated the association between red wine and cancer risk in humans, but high alcohol intake has been shown to increase cancer risk. Moderation is key.
The American Dietary Guidelines define moderate alcohol intake as one drink a day for women and two drinks a day for men.
Another natural anti-inflammatory agent found in grapes is the flavonoid quercetin. Studies have shown that this can also help prevent or slow cancer growth.
Animal studies have shown that quercetin and resveratrol can reduce the risk of atherosclerosis and protect against damage from low-density lipoproteins and bad cholesterol.
These experiments mainly use doses of flavonoids that are much higher than those normally consumed by humans.
Grape polyphenols, such as resveratrol, are believed to have antioxidant, lipid-lowering, and anti-inflammatory properties that help reduce the risk of cardiovascular disease. They have discovered the potential for these effects by preventing platelet build-up, lowering blood pressure, and reducing the risk of arrhythmias.
The American Heart Association recommends increasing your potassium intake and improving blood pressure and cardiovascular health while reducing sodium intake.
A study of data from 12,267 adults in the United States showed that high sodium intake associated with potassium intake increased the risk of death from all causes.
High potassium intake reduces the risk of stroke and prevents loss of muscle mass, thus maintaining bone mineral density.
Effect on blood pressure
Increasing your potassium intake can reduce the negative effects of having too much sodium in your diet.
Grapes are high in potassium. This suggests that it can help reduce the effects of sodium in people with high blood pressure.
Dietary fiber is important for maintaining heart health and cardiovascular health, such as blood pressure. Grapes are a good source of dietary fiber.
Improvement of constipation.
Grapes contain water and fiber. It helps retain water and provides regular bowel movements to reduce the risk of constipation.
Improvement of allergies.
Quercetin has anti-inflammatory properties, so eating grapes can help relieve allergic symptoms like a runny nose, watery eyes, and hives.
However, no human experimentation has been done to test this theory.
A study published in the BMJ in 2013 suggests that certain fruits, rather than juice, can reduce type 2 diabetes in adults.
In a 22-year study of 187,382 people, 6.5% developed diabetes.
However, those who consumed blueberries, grapes, raisins, apples or pears three times a week had a 7% lower risk of type 2 diabetes than those who did not.
The relatively high sugar content of grapes raises the question of whether diabetics can eat safely. The American Diabetes Association recommends eating grapes and other fruits as long as the amount of carbohydrates is counted as part of the diet. The vitamins, minerals and fiber that grapes contain are healthy and sweet.
Effects on diabetic neuropathy and retinopathy
Several studies have shown that resveratrol can prevent diabetic neuropathy, which affects neurological function. Scientists attribute this compound to its neuroprotective effects.
