How can a healthy diet help you fight new coronary pneumonia?

March 28, 2020 / / -- There is a lot of uncertainty about coronavirus, and no one can completely eliminate the risk of contracting COVID-19.
but one thing we can do is eat as healthy as possible.
if we do have COVID-19, our immune system is responsible for fighting it.
studies have shown that improved nutrition helps maintain optimal immune function.
essential for anti-infection include vitamins A, B, C, D and E, as well as minerals iron, selenium and zinc.
below is what we know about how these nutrients support our immune system and what we can eat to get them.
source: Vitamin A Vitamin A maintains the structure of skin, respiratory tract and intestinal cells.
this creates a barrier and is your body's first line of defense.
if fighting infection is like a football game, vitamin A is your front line.
we also need vitamin A to help make antibodies to mediat the pathogens that cause infection.
it's like assigning more people to your team to target an opponent with a ball to stop them from scoring.
, egg yolks, cheese, tofu, nuts, seeds, whole grains and legumes all contain vitamin A.
addition, vegetables contain - carotene, which your body can convert into vitamin A.
are found in leafy, yellow and orange vegetables such as pumpkins and carrots.
2, vitamin BB vitamins, especially B6, B9 and B12, help the body's first reaction after identifying pathogens.
they do this by affecting the production and activity of "natural killer" cells.
natural killer cells work by "exploding" infected cells, a process known as apoptosis.
in a football game, the role is like a security guard intercepting a spectator who wants to break into a stadium and disrupt the game.
B6 is found in cereals, beans, leafy green vegetables, fruits, nuts, fish, chicken and meat.
B9 (folic acid) is abundant in leafy green vegetables, beans, nuts and seeds and is added to commercial bread-making flour.
B12 is found in animal products, including eggs, meat and dairy products, as well as in fortified soy milk (see Nutrition Information Panel).
3, vitamin C and E When your body fights infection, it experiences oxidative stress.
oxidative stress leads to the production of free fundamentals, which can penetrate cell walls, causing substances to penetrate tissues and exacerbate inflammation.
vitamin C and vitamin E help protect cells from oxidative stress.
vitamin C also helps clean up these cell waste by producing specialized cells to produce an immune response, including neutral granulocytes, lymphocytes, and phagocytosphages.
so vitamin C is a bit like cleaning up a football field after a game.
sources of vitamin C include oranges, lemons, limes, berries, kiwis, orchids, tomatoes and peppers.
vitamin E is found in nuts, leafy greens and vegetable oils.
: Vitamin D Some immune cells need vitamin D to help eliminate the pathogens that cause infection.
while exposure to the sun can cause the body to produce vitamin D, food sources including eggs, fish, some milk and margarine brands may add vitamin D (i.e. extra vitamin D).
most people only need a few minutes of outdoor activity on most days.
who are deficient in vitamin D may need supplements.
a review of 25 studies found that vitamin D supplements help prevent acute respiratory infections, especially in people who lack vitamin D.
5, iron and zinc selenium We need iron, zinc and selenium to promote the growth of immune cells.
iron kills pathogens by increasing the number of free fundamentals, which can destroy pathogens.
also regulates the enzyme responses necessary for immune cells to identify and target pathogens.
helps keep the skin and mucous membranes intact.
zinc and selenium are also antioxidants that help remove some of the damage caused by oxidative stress.
iron is found in meat, chickens and fish.
vegetarian sources include legumes, whole grains and iron fortified breakfast cereals.
is found in oysters and other seafood, meat, chicken, dried beans and nuts.
(especially Brazil nuts), meat, grains and mushrooms are good food sources for selenium.
put them together and eat as many foods as possible in each basic food group to increase vitamin and mineral intake.
vitamin and mineral supplements are not recommended for the general public, there are some exceptions.
pregnant women, some people with chronic diseases, and those with abnormal or dietary restrictions may need specific supplements.
consult your doctor, practicing dietitian, or pharmacist.
addition to diet, you can take other steps to stay as healthy as possible in the face of coronavirus.
to stop smoking to improve your lungs' ability to fight infections, perform moderate-intensity exercises such as walking fast, getting enough sleep, keeping social distance, and washing your hands regularly with soap.
