水果是酸的還是鹼的？

Sorry I can only type in English.

Yes, you got different answer that is right because different food with their own PH level. Once they enter to our body, PH level will be changed.

Foods: are they Acid or Alkaline-forming?
Note that a food's acid or alkaline-forming tendency in the body has nothing to do with the actual pH of the food itself. For example, lemons are very acidic, however the end-products they produce after digestion and assimilation are very alkaline so lemons are alkaline-forming in the body. Likewise, meat will test alkaline before digestion but it leaves acidic residue in the body so, like nearly all animal products, meat is classified as acid-forming.

It is important that your daily dietary intake of food naturally acts to balance your body pH. To maintain health, the diet should consist of at least 60% alkaline forming foods and at most 40% acid forming foods. To restore health, the diet should consist of 80% alkaline forming foods and 20% acid forming foods.

In terms of fruits, below are the classification base on fruits AFTER entering our body.

High Alkaline
Lemons, Watermelon, Limes, Grapefruit, Mangoes, Papayas

Alkaline
Dates, Figs, Melons, Grapes, Papaya, Kiwi, Berries, Apples, Pears, Raisins

Low Alkaline
Oranges, Bananas, Cherries, Pineapple, Peaches, Avocados

Low Acid
Plums, Processed Fruit Juices

Acid
Sour Cherries, Rhubarb, Canned Fruit

High Acid
Blueberries, Cranberries, Prunes, Sweetened Fruit Juice

Hope this help : )

所有水果都是不含鹼性的，所以屬酸性，果酸含大量維他命C有抗氧化作用，抗壞血病，每天起碼吃兩個，但榴槤、香蕉之類極少果酸，但亦無鹼性的。

水果是酸的!

一般來講是酸的，因為當中有果酸，即是平時護膚品廣告講那些抗氧化物質。
