4. Pear

Pears are extremely nutritious and full of minerals and vitamins. They are also low in calories and so are considered to be highly beneficial for our body. But do you know that pears also contain crude fiber which can damage the delicate mucous membranes present in the stomach if eaten on an empty stomach? Also, roughage present in pears can damage the gastrointestinal tissues when consumed without eating anything else in the morning. Eating pears is healthy but it is strictly advised to avoid without having breakfast.
