I. Milk and Soy Milk: These two foods contain a large amount of protein. When consumed on an empty stomach, the protein will be "forced" to be converted into energy for consumption, failing to provide nutritional benefits. The correct way to drink them is to consume them with foods containing flour such as pastries or biscuits, or to drink them two hours after a meal, or before bedtime.
II. Sugar: Sugar is a food that is very easy to digest and absorb. Eating a large amount of sugar on an empty stomach can cause the human body to secrete insufficient insulin to maintain normal blood sugar levels in a short period, leading to a sudden increase in blood sugar, which can easily cause eye diseases. Moreover, sugar is an acidic food, and eating it on an empty stomach can also disrupt the body's acid-base balance and the balance of various microorganisms, which is detrimental to health.
III. Yogurt: Drinking yogurt on an empty stomach will weaken its health benefits. However, drinking it two hours after a meal or before bedtime can provide nourishing and health-promoting effects, aid digestion, and help with gas and bowel movements.
IV. Sweet Potato: Sweet potatoes contain tannins and pectin, which can stimulate the stomach wall to secrete more gastric acid, causing discomfort such as heartburn.
V. Persimmons and Tomatoes: They contain a lot of pectin and tannic acid. These substances react with gastric acid to form indissolvable gel-like masses, which can easily lead to stomach stones.
VI. Cold Drinks: Consuming large amounts of frozen food on an empty stomach can cause gastrointestinal spasms. Over time, this will lead to disorders in various enzyme-catalyzed chemical reactions and induce gastrointestinal diseases. It can also cause menstrual irregularities in women during their period.
VII. Bananas: Bananas contain a high amount of magnesium. Eating bananas on an empty stomach can cause a sharp increase in magnesium levels in the body, disrupting the magnesium-calcium balance in the blood, which has an inhibitory effect on the cardiovascular system and is not good for your health.
VIII. Hawthorn and Orange: They contain large amounts of organic acids, fruit acids, hawthorn acid, citric acid, etc. Consuming them on an empty stomach can cause a sharp increase in gastric acid, adversely stimulating the gastric mucosa, and leading to symptoms like bloating, belching, and acid reflux.
