There are some foods that are beneficial to us, but can actually work in a negative way, if taken at a wrong time. For example, there are some foods that should never be taken on an empty stomach. 

Here are some such foods that you may want to know:

However, when eaten on an empty stomach, these ingredients combine with acidic nature of our stomach and can result in stomach block. They put unnecessary pressure on the stomach and can cause stomach ache. This can be dangerous for people who are already suffering from ulcers.

Citrus Fruits: Though citrus fruits like oranges, grapefruits, and lemons are high in vitamin C, fiber and antioxidants, they may irritate your stomach when taken first thing in the morning. The oesophagus lining of your stomach gets enlarged when there is no food to digest and taking these fruits can directly enlarge them even more, causing more friction to your stomach.

Puff Pastry: Pastries can be a good combination for breakfast but it is a strict no on an empty stomach. Pastries and crusts have yeast in them and they simply will not go well for an empty stomach.

Carbonated Drinks: Carbonated drinks are basically bad for health and imagine having them on an early morning. Nothing can be more troublesome for your stomach than having these carbonated drinks first thing in the morning. They up the risk of cancer and heart diseases and can also lead to many other complications. Strictly avoid them on an empty stomach.
