Many expectant mothers must be fully armed to confront normal radiation after they become pregnant. Selecting protective clothing is the first thing mom would think of. Then, is there an easier way to prevent radiation? Today, Xiao Bian introduced several kinds of delicious food that can protect against radiation, nutritious and delicious food. Who are they?
First, red fruit:
1, tomato
Among red fruits rich in an antioxidant vitamin, lycopene, the highest levels are found in tomatoes. Lycopene is the most powerful carotenoid found so far. Its antioxidant capacity is 100 times that of vitamin E. It has a strong ability to scavenge free radicals, resist radiation, and prevent cardiovascular and cerebrovascular diseases. Improve the immune system, delay aging and other effects, as well as "plant gold". So far, no reports of side effects have been found with lycopene, so it is very suitable for long-term health care.
Lycopene is closely related to skin beauty and anti-aging. Studies have shown that lycopene can greatly improve skin allergies, relieving skin dryness and itching caused by skin allergies, making people feel relaxed and happy. In addition, lycopene also has a good protective effect against ultraviolet rays, the enemy of skin aging.
Recommended menu: Tomato scrambled eggs
Since lycopene is a fat-soluble vitamin, absorption after oil cooking is better, and heating can also promote the release of lycopene, so the tomato ripening absorption rate is greater than raw. However, lycopene is less stable and decomposes in environments higher than 50 degrees Celsius, so scrambled tomatoes also cause loss of lycopene.
2, cherry
Cherry ripe red color, exquisitely carved, delicious and delicious, nutritious, high value of health care, but also "with peach" other name. Anti-anemia, promote blood production. Cherry has a high iron content and is the first of a variety of fruits. Iron is a raw material for the synthesis of human hemoglobin and myoglobin. It plays an important role in human immunity, protein synthesis, and energy metabolism. It is also closely related to brain and nerve function and aging process.
The regular cherry can supplement the body's demand for iron and promote the regeneration of hemoglobin. It can prevent and treat iron deficiency anemia, enhance physical fitness, and improve brain function.
Second, cruciferous vegetables and fruits:
A variety of legumes, olive oil, sunflower oil, rapeseed, vegetables, mustard, cabbage, carrots and other cruciferous vegetables and fresh dates, oranges, kiwi and other fresh fruit.
All kinds of beans, olive oil, sunflower oil and cruciferous vegetables are rich in vitamin E, while fresh dates, oranges, kiwifruit and other fruits are rich in vitamin C, vitamin E and vitamin C are antioxidant vitamins, have antioxidant activity , It can reduce the peroxidation caused by computer radiation, just like giving our skin a layer of “ballistic armor†to reduce skin damage.
Fresh fruits and vegetables have anti-radiation effect, but also they can make the blood alkaline, dissolve the toxins deposited in the cells, and excrete it with the urine.
Foods containing carotene: cod liver oil, animal liver, chicken, egg yolk and broccoli, carrots, spinach, etc.
carrot:
Carrots are rich in natural carotenoids and are powerful antioxidants that protect human cells from damage and prevent cells from becoming cancerous. The long-term consumption of carrots can make the human body less vulnerable to radiation and excessive ultraviolet radiation. In addition, natural carotene can increase human immunity, delay cell and body aging, and reduce the incidence of disease. At present, natural carotene is also used in cosmetics in foreign countries to exert its radiation protection, protect, moisturize the skin and prevent aging.
These foods are rich in vitamin A and beta-carotene, which not only synthesize rhodopsin, but also make it easier for the eyes to see things in the dark. Therefore, these foods not only help to counteract computer radiation but also protect And improve vision.
Recommended menu: carrot fried broccoli
Since beta-carotene is a fat-soluble vitamin, it needs to be fried with oil, which is more beneficial to absorption.
Selenium-containing foods: sesame, malt, and astragalus, followed by yeast, eggs, beer, red shrimp, lobster, tigerfin fish, tuna, seafood, garlic, mushrooms, etc.
Selenium, a trace element, has an antioxidant effect. It acts by blocking the body's peroxidation to resist radiation and delay aging. Selenium-rich foods are the first choice for sesame, malt and jaundice.
Recommended Recipe: Black sesame paste
Sesame is not only rich in selenium, but also rich in vitamin E with antioxidant effects, the dual role is more conducive to mothers to withstand computer radiation.
Fifth, foods rich in collagen elastic substances
The representatives of this type of food are kelp, seaweed, sea cucumber, animal skin, bone marrow, etc., because the collagen in food has an adhesive effect, it can stick out of the body's radioactive material and excreted from the body, and the animal skin The elastic material contained also has the function of repairing damaged skin.
PCR ( Polymerase Chain Reaction)
It provides a way to make more copies of a portion of DNA.
We need to have PCR ingredients that include DNA portion, Buffer solution, Primer+DNA (tap polymerase), and Nucleotides during the preparation step.
In the step of PCR sequence, there are three steps in this section.
Step 1 Denaturation
The addition of heat is needed to separate the two strands of the DNA molecule.
Step 2 Annealing
Temperature, is going to be cool in this step, should allow the primers to bind to the specific segments.
Step 3 DNA Synthesis
To make more copies of the DNA.
Those three steps above keep repeating to make enough copies of the DNA fragments. It is the principle of how PCR machine works.
SARS-Cov-2, One test type that uses a sample from a nose or throat swab in a 'PCR test'. The goal is to make enough copies of the viral cDNA in order for it to be detectable.
