Foods That Weaken Immune System

You probably already know that keeping your immune system healthy is essential for keeping away health issues before they start, and you may even know just how closely connected it is to your gut health, but you might not realize just how much of an impact certain foods can have on it. Adequate sleep, exercise, and a healthy diet all contribute to maintaining the body’s defence system. There are many foods that weaken immune system but knowingly or unknowingly we consume them quite frequently. Here are some foods that weaken your immune system and it’s best for you to stay as far away from them as possible.

Fried Foods

In addition to being full of fats that could increase your cholesterol level, fried foods can also trigger inflammation, leading to reduced immunity. Cutting back on fried foods or better yet, getting rid of them altogether could help restore your body’s natural defenses.

Sugary Snacks

Sugar directly impacts your immune system by competing for space with vitamin C, a core nutrient for your immune cells. The more sugar you consume, the harder it is for your immune cells to get the vitamin C they need to function, resulting in a decrease in effectiveness lasting for hours after you consume the sugar.


Caffeine may make your mornings better, but it can also have some unwanted effects on your immune system. That boost of energy that helps you wake up in the morning can also come with the unpleasant side effect of boosted cortisol levels. Cortisol (a hormone released in response to stress) does a number on your metabolism and mood, and it can also lower your immune function if you regularly have high levels of it flowing throughout your body.


You know soda isn’t the best choice when you want to hydrate, but is diet soda a better option? Unfortunately not; while it’s free from microbiome-disrupting sugar, diet soda is chock full of artificial ingredients, including sweeteners like aspartame, saccharin, and sucralose, none of which is good for your immune system.

If you want to stay healthy then you must avoid all these foods that weaken your immune system and go for the ones which are rich in Vitamin C and other nutrients that are good for your immunity. Also check for how to increase immunity power in body naturally in our portal.
