As the internal organs of the elderly gradually age, their physiological functions weaken. This includes poor digestion, slowed intestinal motility, atrophic gastric mucosa, and excessive stomach acid, and it is often accompanied by various diseases. Therefore, it is not advisable to eat large amounts of fruit at once; instead, one can adopt a "small, frequent meals" approach.
Those who frequently experience stomach acid should not eat fruits rich in organic acids, such as plums, hawthorns, and lemons.
For those with frequent constipation, eating more fruits like peaches, bananas, and oranges is beneficial, as these have a mild laxative effect. However, persimmons contain a large amount of persimmon gum, and eating too many can worsen constipation.
For those with frequent diarrhea, avoid eating the aforementioned fruits with a laxative effect. Apples can be eaten in moderation as they have an astringent and binding effect.
Individuals with heart disease or edema should avoid fruits high in water content, such as watermelons and coconuts, to avoid increasing the burden on the heart and exacerbating edema.
Diabetics should not only eat less sugar but also reduce their intake of fruits high in sugar, such as pears, apples, and bananas.
Hepatitis patients can benefit from eating more fruits rich in vitamin C, such as oranges and fresh jujubes, as this is favorable for the treatment and recovery of hepatitis.
Do not eat fruit before meals, as it may affect normal eating and digestion.
Elderly patients with conditions such as nephritis and hypertension must avoid eating too many bananas. Although bananas are cool and slippery, they are also high in potassium.
