Covid19: Food groups that weaken your immune system
The immune system helps protect the body against contractible illnesses, such as the common cold and the flu. Nutrition is an important part of ensuring that the immune system stays strong, especially during the coronavirus pandemic.
Regularly consuming certain unhealthy foods may prevent the immune system from functioning properly. This may reduce its ability to function at an optimal level.
Some research suggests that diets high in added sugar and excess salt are associated with an increased risk of autoimmune conditions. This means that diet plays an important role in keeping the immune system healthy.
On the other hand, eating foods that contain certain nutrients, such as vitamin C, may help boost the immune system.
This article will discuss which foods weaken the immune system and which foods may help boost it.
Processed foods tend to contain unhealthy fats, sugars, and additives, which can improve taste, texture, and shelf life. These may weaken the immune system.
Some processed foods include microwave meals, breakfast cereals, chips, cakes and cookies.
One 2017 study found that eating foods containing additives may lead to an increase in the risk of several immune conditions. The study looked at additives such as sucralose, aspartame, carboxymethylcellulose, polysorbate-80, sodium, and carrageenan.
The researchers point out that people who eat a diet that contains foods with additives are more likely to have obesity, immune inflammation, and insulin resistance.
Eating sugars and fats in processed foods can also lead to consuming too many calories, which can increase a person’s risk of obesity.
When a person has obesity, this leads to inflammation. This inflammation can lead to insulin resistance, cirrhosis, and liver failure, as well as immune system dysregulation.
Foods high in sugar
Consuming foods that are high in sugar may weaken the immune system. Some foods that may be high in sugar include preserves, marmalades, confectionary, cookies and cakes, flavored milk and sweetened dairy products, sugary breakfast cereals, and sugary drinks such as soda.
People with high sugar diets have a higher risk of several chronic conditions, including coronary heart disease and diabetes.
Also, eating a diet high in sugar may limit the immune system’s effectiveness in combating disease. It may do this by reducing the effectiveness of white blood cells and potentially by increasing inflammatory markers in the blood.
Processed foods and refined carbohydrates, such as white flour and refined sugar, are associated with increases in inflammation and oxidative stress, which can impact the immune system.
Some foods that contain refined carbohydrates include: white rice, white bread and refined sugar.
