However, nutritionists warn: Eating red grapes incorrectly can reduce the effectiveness or cause digestive discomfort.
According to Dr. - nutritionist Priya Khuana (USA), red grapes are rich in saponin and flavonoids, two active groups that can help reduce oxidative stress, a factor related to the aging process of kidney cells.
Thanks to that, this fruit is often included in the diet of people who want to maintain urinary tract health and protect the filtered organs.
However, Ms. Khuana noted: "Red grapes are rich in soluble fiber. If you eat too much at the same time, especially when not used to it, users may experience bloating or indigestion".
Therefore, experts recommend eating a moderate amount, combined with drinking enough water to make the urinary system work more gently.
In addition, dried red grapes, a popular form on the market, often have a higher natural sugar content than fresh fruit. For those who need to control blood sugar, nutritionist Sara Haas ( Academy of Nutrition and Dietetics, USA) said that they should prioritize fresh red grapes or eat them with meals to avoid sudden increases in blood sugar.
Experts also say that red grapes only support kidney health when combined with a healthy overall diet: limit salt, drink enough water, do not abuse processed foods. No fruit can replenish kidneys quickly if your lifestyle is unbalanced.
