Greasy foods are not only found at fast food joints but also workplaces, restaurants, schools, and even your home.

Most foods that are fried or cooked with excess oils are considered greasy. They include french fries, potato chips, deep-dish pizzas, onion rings, cheeseburgers, and doughnuts.

These items tend to be high in calories, fat, salt, and refined carbs but low in fiber, vitamins, and minerals.

While they can be an enjoyable treat on special occasions, greasy foods negatively affect your body and health in both the short and long term.

Here are effects of greasy foods on your body

May cause bloating, stomach pain, and diarrhea
Among the macronutrients carbs, fat, and protein fat is the most slowly digested.

Because greasy foods contain high amounts of fat, they slow stomach emptying. In turn, food spends more time in your stomach, which can cause bloating, nausea, and stomach pain.

In people with digestive complaints, such as irritable bowel syndrome (IBS), chronic pancreatitis, or a stomach bug, high levels of fatty foods may trigger stomach pain, cramping, and diarrhea.

May impair your gut microbiome
Greasy foods are known to harm the healthy bacteria that live in your gut.

This collection of microorganisms, also called the gut microbiome, affects the following:

Digestion of fiber. Bacteria in your gut break down fiber to produce short-chain fatty acids (SCFAs), which have anti-inflammatory effects and may protect against digestive disorders
.
Immune response. The gut microbiome communicates with immune cells to help control your body’s response to infections.

Weight regulation. An imbalance of gut bacteria may contribute to weight gain .

Gut health. Disturbances of the gut microbiome are linked to the development of IBS, while probiotics live, healthy microorganisms found in certain foods may help improve symptoms.

Heart health. Healthy gut bacteria may help boost heart-protective HDL cholesterol, while harmful species may produce artery-damaging compounds that contribute to heart disease.

A high fat diet, such as one rich in greasy foods, may damage your gut microbiome by increasing the number of unhealthy gut bacteria and decreasing the number of healthy ones.

These changes may be associated with obesity and other chronic illnesses, such as cancer, heart disease, diabetes, and Parkinson’s disease.
