1. Spicy food

Though majority of us are under the impression that it is healthy to have a glass of fruit juice to start your day, it may not be the case. Starting your day with a tall glass of fruit juice as it may put an extra load on the pancreas that are still waking up after long hours of rest. With the stomach being empty, sugar in the form of fructose in fruits can cause an overload on your liver. Processed sugar is even worse, so avoid breakfast desserts or overly sweet smoothies.3. Aerated drinks

Your stomach excretes acid to help in the digestion of your food, and if there's no food in your tummy, you're just introducing additional acid into your digestive system which might lead to stomach cramps or pain.4. Cold beverages

Citrus fruits

Moreover, too much fiber and fructose in fruits can also make slow down your digestive system if eaten on an empty stomach. You should especially avoid eating fruits with tough fibers like guava and oranges early morning.
