Doctor CKI Dinh Tran Ngoc Mai, Department of Nutrition - Dietetics, University of Medicine and Pharmacy Hospital, Ho Chi Minh City, answered: Purple grapes contain many antioxidants, especially resveratrol, which can help reduce uric acid levels in the body and support the treatment of gout.

Grapes also contain a lot of vitamin C, according to research vitamin C helps to eliminate uric acid from the body better. So not only purple grapes, fruits and vegetables containing a lot of vitamin C are recommended to help control gout.

However, eating a lot of fruit containing fructose is also a factor that increases uric acid in the blood. Eating a lot of fruit leads to increased uric acid levels through mechanisms such as increasing uric acid production and inhibiting uric acid excretion through the kidneys. This is why people with gout or at high risk of gout should limit fructose consumption from sweetened beverages and high-fructose fruits.

Instead, to supplement vitamin C, you should eat a lot of vegetables and only eat fruit in moderation, about 300-400 grams/day, and prioritize choosing fruits that are less sweet such as guava, papaya, kiwi, berries...

In addition to reducing uric acid, purple grapes also have many other health benefits such as:

Antioxidants : Resveratrol and flavonoids in purple grapes help fight free radicals, protecting cells from damage.

Boost Heart Health : Purple grapes may help reduce the risk of heart disease by lowering blood pressure and cholesterol levels.

Improve brain function : Resveratrol in purple grapes can improve brain function and protect against neurodegenerative diseases like Alzheimer's.

Supports the digestive system : The fiber in purple grapes helps improve digestive function and maintain intestinal health.

Boosts the immune system : Vitamin C and antioxidants in purple grapes help boost the immune system.

The specific dosage of purple grapes for treating gout has not been clearly determined through research.

Consumption of purple grapes should be combined with a balanced diet and healthy lifestyle, limiting alcohol to achieve optimal health benefits.
