Someone told me that eating fruits right after dinner is not good, but I've been eating fruits after lunch for a long time.

Is this really an issue?

No its not an issue any time. Fruits are the source of fibers so they cant harm you. It is advised to have fruits to maintain a good health.

I'm not really sure but for me that is good eating fruit after dinner is more better than to eat a sweet desert, fruit is very good to alternate for deserts and it's healthy..i think there's nothing bad about that.

Natural Hygienists have known for a long time that fruit doesn’t combine well with other foods. The reason is that fruit contains simple sugars that require no digestion. Thus, they will not stay for a long time in the stomach. Other foods, such as foods rich in fat, protein and starch, will stay in the stomach for a longer period of time because they require more digestion. So if you eat fruit after a meal, the fruit sugar will stay for too long in the stomach and ferment. This is why people experience digestive trouble when eating fruit that way. They then blame that particular fruit for their trouble and claim that they are “allergic” to it.

I cannot really see why anyone would doubt that it would be good to eat fruit after meals. Any food that occurs naturally is good to eat, and certainly a banana would be preferable (diet wise) to a chunk of chocolate ice-cream! Any concerns about the acidic nature of fruit can be overcome by using a toothbrush after the meal, but come on guys, surely the answer is obvious, fruit is good for you anytime!
