Excessive consumption of fresh lychees can easily lead to lychee disease! How to tell if fruit has high sugar content?

Now is the lychee season. Lychees contain high sugar content. Excessive consumption may cause digestive tract discomfort, hypoglycemia, and even shock in severe cases. Experts suggest that it is appropriate to eat 5-6 fresh lychees a day, and no more than 10 for adults. So, here comes the question:

1. How to judge the sugar content? Does eating something sweet mean it’s high in sugar?

2. Which fruits have high sugar content?

1. Does eating something sweet mean it contains high sugar content?

Regarding how to judge the sugar content of fruits, someone said, try it. Sweet fruits have high sugar content, while unsweet or sour fruits have low sugar content. For example, hawthorn must have less sugar!

Is this method of judging sugar content based on the taste sweetness of fruits reliable?

The answer is: unreliable.

The exact name of sugar in fruits is "carbohydrates", and there are four main categories: glucose, fructose, sucrose and starch. Sweetness is a relative value, usually with sucrose as the benchmark. The taste sweetness of the four types of sugars in fruits is from high to low:

Fructose (1.7 times sucrose) Sucrose Glucose (0.7 times sucrose) Starch (almost no sweetness).

So, if one type of fruit is mostly fructose and another is mainly glucose, the sweetness will taste similar, but the sugar content may be very different.

2. Which fruits have high sugar content?

Since it is impossible to know the sugar content of fruits based on their taste alone, which fruits have high sugar content and which ones have low sugar content? We have put together a table for reference. Actual fruits will vary slightly due to differences in varieties and plantings.
