2. Persimmon Skin Should Not Be Eaten
Some people feel that eating persimmon fruit together with the skin taste betten than just eating the flesh by itself. Scientifically this is not advisable because the vast majority of persimmon tannin is concentrated in the skin. If eaten together with its skin the formation of gastric persimmon stone is easier, especially when the astringent process is incomplete, as its skin contains more tannic acid.

3. Do not eat pesimmon together with high-protein crabs, fish, shrimp and other foods
In Chinese medicine, crab and persimmon are considered "cold foods", therefore they cannot be eaten together. From the perspective of modern medicine, crab, fish and shrimp contains high level of protein and thus under the effect of the tannic acid, it is easy to solidify into blocks, namely, stomach persimmon stone.

4. Diabetics Should Not Eat Pesimmon
Persimmon has 10.8% sugars content and mostly are simple pairs of sugar and simple sugars (sucrose, fructose, glucose is such), which can be easily absorbed by our body after eating which may result in hyperglycemia. For diabetic people, especially those with poor glycemic control, it is even more harmful.

5. Enough is enough
The tannic acid in persimmon together with dietary calcium, zinc, magnesium, iron and other minerals form compounds that cannot be absorbed by the body so that these nutrients cannot be used and therefore eating persimmons can easily lead to a lack of these minerals. And because there is more sugar in persimmon, eating the same amount of pesimmon compared to apples or pears will make one feel full faster hence will affect one's appetite and reduce the intake of meals. Generally, with an empty stomach, it is advisable not to take more than 200 grams of persimmon.
