Regular exercise, good sleep habits, balanced diet and stress control are the most important ingredient for strengthening your immune system.
It takes your precious time and effort that helps you stay healthy, but what if all your hard work is wasted on just one particular diet?
According to research reports and medical experts, too much sugar facilitates the spread of bacteria or viruses within the body system because of its effect, the initial defence system does not work properly.
According to Dr Michael Roisen of the Cleveland Clinic in the United States, this is the reason why diabetics suffer from various infections because their immune system is not working properly.
You will be amazed at how harmful sugar is to the immune system.
How does sugar affect the immune system?
Aside from chronic diseases such as diabetes and heart disease, sugar consumption also adversely affects the body’s ability to fight viruses or other infections.
You may not know it, but to fight disease, the body needs specific cells, called white blood cells, which are greatly affected by excessive consumption of sweets.
A study on fruit flies found that excessive consumption of sweets results in white blood cells being unable to do their job and failing to control viruses and bacteria.
Another study found that high blood sugar affects the immune system in people with diabetes.
High-sugar foods lead to cause type 2 diabetes, meaning that too much sugar can make you diabetic, and people with COVID-19 have a higher risk of developing serious complications if they have diabetes.
How much sugar intake can weaken the immune system?
One study found that just 75 grams of sugar a day is enough to weaken the immune system, and once white blood cells are affected, it is thought to slow down the immune system for up to 5 hours.
This means that even 8 hours of sleep a day, exercise and a balanced diet will not prevent the loss of a few soft drinks or sweets throughout the day.
It is difficult to calculate 75 grams of sugar, but note that a soft drink can contain up to 40 grams of sugar.
How much sugar can be consumed in a day?
The World Health Organization (WHO) and the US Agency for International Development (CDC) have advised that no more than 6 teaspoons or 25 grams of sugar per day should be consumed, including the amount of sweetness in your tea.
If you limit your sugar intake (ie 25 grams daily) with a balanced diet, your immune system will work better and protect you from the disease.
As you may know, a strong immune system does not prevent coronavirus infection, but it does prevent some of its deadly effects.
