Polovinskaya warned that any citrus fruits, including oranges, are a strong allergen. Therefore, it is dangerous to eat them in large quantities, as this can cause allergic reactions. With diseases of the gastrointestinal tract, you should be careful when eating fruit on an empty stomach. In addition, the high acidity of an orange can damage tooth enamel.
But, despite all this, when consumed, oranges lower blood pressure, strengthen the walls of blood vessels, lower cholesterol levels, and reduce the risk of cardiovascular diseases. In addition to this, they contain a large number of micro and macronutrients, including a daily dose of vitamin C and flavonoids, which regulate body growth and have an antioxidant effect.
