A Health Warning: 8 Fruits That Can Be Harmful When Overindulged.

1. Jujube:

Eating jujubes can nourish the blood, lower blood pressure, and enhance the body's immunity. At the same time, jujubes also contain large amounts of vitamins, various trace elements, and sugar, and their vitamin C content is the highest among all fruits. Although jujubes are good, they should not be eaten in excess. They are high in sugar and can easily cause cavities; jujubes can also generate phlegm and dampness, so people with a full lower abdomen and constipation should not eat them. Jujubes are sticky and difficult to digest, and eating too many can affect appetite and digestive function.

Expert reminder: Never eat rotten or spoiled jujubes. In mild cases, it can cause dizziness, and in severe cases, it can be life-threatening.

2. Apple:

Apple juice can stop diarrhea, eating it on an empty stomach can treat constipation, and eating it after a meal can aid digestion. However, apples are rich in carbohydrates and potassium salts, and excessive intake is not good for heart and kidney health. People with coronary heart disease, myocardial infarction, nephritis, or diabetes should strictly avoid eating too many.

Plum juice and green pear

3. Pear:

It has effects such as relieving coughs, reducing phlegm, and clearing dryness, and is effective for treating coughs, asthma, wind-heat, and pharyngitis. Due to its cold nature, people with a weak spleen and stomach, clear drooling from the mouth, or loose stools should be cautious; also, due to its high sugar content, overconsumption can raise blood sugar, so people with diabetes should eat less.

4. Citrus:

It contains a large amount of carotene, which is converted into vitamin A after entering the bloodstream and accumulates in the body, causing the skin to turn yellow, leading to "carotenemia," commonly known as "orange jaundice," which is then followed by symptoms such as nausea, vomiting, loss of appetite, and general weakness.

Expert reminder: After developing "orange jaundice," you should consume a moderate amount of vegetable oil and drink plenty of water to accelerate its dissolution, conversion, and excretion.

5. Persimmon:

It contains large amounts of vitamins A and C, as well as tannic acid, and is rich in nutrients. It has effects such as lowering blood pressure and stopping bleeding, clearing heat and lubricating the intestines, and moistening the lungs and promoting fluid production. However, it contains a large amount of persimmon gum and pectin, which, when combined with stomach acid, coagulates into a fibrous mass, known as a "bezoar," leading to epigastric pain and indigestion.

The pectin in persimmons has an astringent effect, so people with constipation should avoid them; it should not be taken on an empty stomach, and it is especially not suitable to be eaten with crabs or sweet potatoes, as this can more easily cause a bezoar.

6. Pomegranate:

It contains a large amount of fructose and various vitamins and minerals. It is sweet in taste and warm in nature, making it a fruit for damp-heat conditions. Pomegranates are effective for dysentery, rectal prolapse, and pharyngitis, but people with a weak constitution, yin deficiency, and internal heat should be cautious; those with early-stage diarrhea and damp-heat should also not eat fresh fruit. Even for healthy people, it should not be eaten in excess, as too much can damage teeth and cause loss of appetite.

Pomegranate peeling method

7. Water chestnut, water caltrop:

Many people eat raw water chestnuts by biting the skin with their mouth and eat raw water chestnuts without peeling them, and without disinfection and sterilization, it is very easy to get infected with fasciolopsiasis. The fasciolopsis worm is plump and, when observed under a microscope, looks very much like a slice of ginger. After entering the human body, it parasitizes in the small intestine, leading to malnutrition, weight loss, and anemia, and it is more harmful to children.
