Can blueberries enhance physical stamina?

Generally speaking, blueberries may have a mild auxiliary effect on enhancing physical strength, but attention should be paid to the amount consumed, and one should not rely on them excessively. Detailed analysis is as follows:

Blueberries are common fruits containing natural fructose, glucose, B-complex vitamins, and potassium. Among these, B-complex vitamins participate in the body's energy metabolism, helping convert nutrients into energy more efficiently, thus providing slight support in relieving physical fatigue. However, blueberries have a low energy density and mainly consist of carbohydrates, lacking key nutrients such as protein and fat that are essential for sustaining long-term physical stamina. Therefore, relying solely on blueberries to meet the body's energy demands during high-intensity activities is difficult. Additionally, blueberries have a relatively high sugar content; excessive consumption may cause blood sugar fluctuations and, due to excessive fiber intake, increase the burden on the gastrointestinal tract, potentially causing abdominal distension.

Blueberries should not be eaten in large quantities on an empty stomach, as the fruit acids they contain may irritate the gastric mucosa and cause stomach discomfort. It is recommended to consume them with whole wheat bread, eggs, or other ingredients to ensure balanced nutrition. The suggested intake per serving is 100-200 grams.
