If you really don’t want to discard them all, you can roughly follow the principle: when the spoiled part does not exceed 1/3 of the whole fruit, you should remove 1/2 and eat it; when the spoiled part exceeds 1/3 of the whole fruit, then the whole fruit Don''t eat it.

　　5. Treat fruit ripeners and bulking agents correctly

　　Like animals, the life activities of plants are regulated and controlled by some chemical substances. It has been found that plants have five major types of natural hormones, namely auxins, gibberellins, cytokinins, abscisic acid and ethylene. Their roles in plants vary; auxin promotes long roots, gibberellin promotes long stems and leaves, cytokinin promotes bud development and fruit development, abscisic acid promotes senescence and resists adversity, and ethylene promotes fruit ripening. These hormones and their chemical mimics have long been used in agricultural production. For example, the use of auxins to promote root development can make transplanted fruit seedlings easier to survive; treatment with gibberellins can make the fruit without seeds; treatment with ethylene can make green bananas turn yellow and mature... The widely used plant hormones are all regular products approved by the state. Their toxicity and residues meet the requirements and should be safe.

　　 The most closely related to fruits are "ripening agents" and "swelling agents". Everyone knows that the fruit will become soft after maturity, and it may be broken in two or three days, and it will be more rotten after bumping, which is difficult to store and transport. If you want to bring a lot of fruits from a distance, you must pick them when they are ripe, and when they reach the place of sale, in order to make them have a good appearance and allow them to reach an edible state, you must use "ethylene vinyl" ( May release ethylene) and other ripening. The bulking agent is a growth regulator that promotes fruit growth and can increase yield and make the fruit look good. "Curing agent" and "swelling agent" will not cause safety problems, but will reduce the quality of fruit. Some fruits are large, but the flavor is not good; some fruits look beautiful, but the taste is not sweet. When consumers buy fruits, do not blindly pursue large fruits and beautiful appearance, and do not choose unusually large fruits.

　　. How to eat fruits in patients with diabetes

　　Fruits are one of the important components of a balanced diet. "Guidelines for the prevention and treatment of type 2 diabetes in China 2007" pointed out that the sugar of diabetic patients should come from vegetables, beans, whole wheat grains, oats and fruits containing high dietary fiber. It can be seen that diabetics can eat fruits. However, fruits usually contain more sucrose, glucose and fructose. In order to avoid the rapid increase of blood sugar after eating fruits, the following should be noted:

　　①Control intake? Do not exceed 100-200 grams per day, In particular, don''t concentrate on eating at once, it is best to eat separately.

　　②To reduce the staple food after eating fruits? This can control the total sugar intake. Generally eat 100 to 200 grams (2 to 4 two) of fruit, roughly reduce 50 to 100 grams (~ 1 two) of staple food.

　　 ③ Eat in the dining room (such as between breakfast and lunch) or before going to bed? Avoid eating fruits and staple food at the same time. It is generally not recommended to eat fruits immediately before or after meals.

　　④Choose fruits with less sugar content? What fruits have less sugar content? It is often impossible to draw a correct conclusion by looking at the "Food Composition Table", because the data on the food composition table detects the fruit Sugars (both sugar and starch, and even some dietary fiber). What''s more, even the same kind of fruit will contain different sugars because of the different origin and growing environment. For example, watermelons of the same variety are very sweet and some are not too sweet, with a large difference in sugar content. Choose according to the sweetness and non-sweetness of the fruit, which is simple and reliable. Simply put, people with diabetes can eat a variety of fruits, and don’t choose particularly sweet ones for each kind of fruit.

　　 The best way is to combine the results of blood glucose monitoring with diabetics and find out the right time, variety and quantity to eat fruits.
