Breast-feeding mothers need to ensure a balanced diet in order to provide their baby with adequate and nutritious milk. However, although some foods are rich in nutrients, they may also cause harm to the baby and mothers must not eat it indiscriminately. What are the things that cannot be eaten during breastfeeding, and mothers must remember clearly.
1, irritating food
Can not eat irritating food during breast-feeding, because eating irritating food during breast-feeding, will enter the baby's body from the milk, affecting the baby's health. However, eating a small amount of condiments, such as pepper, sour vinegar, etc. is still possible.
2, back to the food
Breastfeeding can not eat foods that inhibit the secretion of milk, such as leeks, malt water, ginseng and other foods.
3, chocolate
Do not eat chocolate during breastfeeding because the theobromine contained in the chocolate penetrates into the breast milk and accumulates in the infant. Theobromine can damage the nervous system and heart, and make muscles loose, increase urine output, so that infants indigestion, sleep instability. Maternal eat more chocolate will affect appetite, body fat.
4, pickled products
Breast-feeding can not eat preserved fish, meat and other foods. Normal adult daily salt amount is 4.5 to 9 grams, according to usual habits, do not eat salt, do not eat too salty. Too much salt in the lactating mother will increase the burden on the kidney, and it will also adversely affect the kidney and increase the blood pressure.
5, fried food
Breast-feeding can not eat fried foods, because fried foods are difficult to digest, maternal digestion is weak, and fried food nutrition in the frying process has lost a lot of maternal eating is not good for restoring health.
6, MSG
During the lactation period, excessive MSG can not be eaten, and consumption of MSG has a serious impact on the development of infants, especially for infants under 12 weeks, causing adverse effects such as infant mental decline, growth retardation and the like. Mast sucking MSG is best not to eat, do not greedy fresh Dundun MSG.
7, iced, cool fruit
Everyone likes to eat iced fruit in the summer. Breastfeeding mothers must eat normal fruits. If the fruit is taken from the refrigerator, it should be eaten for half an hour at room temperature. Otherwise, the milk mother can easily cause the baby to diarrhea after eating the cold food.
Food has coolness and warmth, as do fruits. Most of the fruits in summer are cool fruits such as melons, watermelons, melons, pears, kiwis, mangoes, grapefruits and so on. Cold fruit eat more easily lead to indigestion, if breast-feeding mothers eat too much watermelon and other cold fruits, it can easily lead to baby diarrhea. Hawthorn, cherry, pomegranate, lychee, etc. are warm fruits, but excessive consumption in the summer is easy to get angry, breast-feeding mothers should not eat more.
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.
