Have you ever had blisters on and around your lips, or a stomach ache after eating? Or do you get colds a lot? If this is the case, you should suspect a "compromised immune system".
When immunity decreases, the ability to eliminate bacteria and viruses decreases, leading to various inflammatory diseases. This immunity is closely related to nutrition, and a lack of certain nutrients can lead to a decrease in immunity. So, what nutrients are deficient in which immunity decreases?
When many people think of immune nutrients, zinc is probably the first thing that comes to mind. Zinc plays an essential role in many tissues with rapid cell turnover, such as the immune system, and influences various aspects of the immune response process, as well as the initial response to viral infection.
If you are deficient in zinc, your immune system will be weakened, making it easier for infections to occur. In this regard, in 2020, Indonesia published a study on 826 preschool children. In the group that took zinc supplements, there was an increase in the cellular immune response, which induces T cells, which are immune cells, to eliminate cells infected with the virus.
However, just because it's an important nutrient for immunity doesn't mean you should get greedy and consume too much of it. In particular, if zinc is taken on an empty stomach, it may cause gastrointestinal disorders such as abdominal pain and nausea, so it is recommended to take it after meals as much as possible.
Vitamin D, also nicknamed the "anti-cancer vitamin," stimulates the production of T cells and B cells that produce antibodies to fight off external risk factors such as viruses.
In this regard, studies have shown that people diagnosed with vitamin D deficiency have a much higher risk of becoming seriously ill if they contract COVID-19 compared to those with normal levels.
Vitamin D is synthesized from ultraviolet light, but not many people are outdoors to synthesize enough vitamin D. That's probably why many people take it as a vitamin D supplement.
One tip when choosing a vitamin D formulation is to make sure that the type of vitamin D you get is vitamin D3. This is because vitamin D3 is synthesized in the skin when we are in the sun, and it is active and absorbed by the body.
Vitamin C is often referred to as the "best vitamin for colds." This is because it resists infection by stimulating the function of various cells in the immune system.
A 2013 Cochrane review of 29 studies found that vitamin C supplementation of at least 200 mg daily reduced the incidence of colds by half in people with high levels of physical stress, such as athletes and military personnel. In addition, vitamin C has not been observed to prevent colds in people who do not have a cold, but it has been shown to reduce the duration and severity of colds in those who already have them.
So, if you're physically overworked, taking vitamin C may help you manage your immune system.
Today, we've introduced three ingredients that are essential for immune function. Don't forget that basic health care through regular lifestyle and regular exercise is a priority.
That concludes this week's Demand Clinic. I appreciate it
