Some twins look alike, and some don't look like them much, and that's because there are two types of twins, one is an identical twin and the other is a fraternal twin.
One
Identical twins look very similar because the mother simply excretes an egg that binds only to one sperm and eventually splits into two embryos as the cell divides.
That is to say, these two brothers or sisters, their gender must be the same, and the appearance is very similar, even like some parents can not distinguish who they are.
And the fraternal twins do not look particularly like each other, like two sisters or two brothers born at the same time, or it may be a dragon and phoenix fetus.
Because the mother secreted two eggs at the same time and combined with two sperm, and finally became two children, their sperm eggs have different genes.
Many scientists will use identical twins to do experiments when doing experiments, and find out what kind of impact different feeding methods or different education methods will have on children.
Two
Xiao Gang and Xiaoping are identical twins, the two brothers have looked very similar since childhood, when they were children, they were exclusively breastfed, and the height and weight difference between the two people was not too big.
But after the child was weaned after the age of one and a half, the mother decided to buy milk for the two brothers to drink, when the child did not like to drink milk powder, the mother directly bought milk for the child.
When buying milk, my mother bought a carton of breakfast milk and a carton of pure milk, and it turned out that Xiao Gang usually only liked to drink pure milk, while Xiao Ping usually only liked to drink breakfast milk, and exchanged the milk of the two brothers, and both of them were unwilling to drink.
So every time my mother went to buy milk, it was a carton of pure milk and a carton of breakfast milk, because the milk that the two brothers liked was different, and the other foods were similar, that is, the types of milk were different.
I have been drinking like this for more than 5 years, and when the child is 6 years old and ready to go to elementary school, the mother took the two children to go to the physical examination and found that the height and weight of the twin brothers and the physical examination data have changed.
One of the twin brothers drank breakfast milk, the other drank pure milk, and after 5 years the gap was large
Gap one: Dental health
Drink breakfast milk Xiaoping already has three caries, the doctor recommends to fill the teeth, because this is the big teeth need to be replaced until the child is about 11 years old, if you do not make up in time now, in case the caries is very serious, it may affect the dental nerves, affect the future permanent teeth.
And drink pure milk small teeth are still very healthy, there is no carious hole, the doctor suggested that when the child grows six-year-old teeth, do a fissure seal on it, usually pay attention to brushing care.
And the mother thought that she gave Xiaoping to drink breakfast milk, and Xiao Gang drank pure milk.
When I think of myself looking at the nutritional ingredient list of breakfast milk and pure milk, the ingredient list of breakfast milk has milk, water, sugar, and various additives, while pure milk only has raw milk in it.
So I consulted the doctor, I, a child with caries, usually drink milk with sugar, this child without caries usually drinks milk without sugar, is this related?
The doctor said that there must be a relationship, white sugar for the child's teeth is a very clear damage, love sugar children, these sugars are easy to destroy the health of the child's teeth, the formation of caries holes.
Gap two: the difference in height
Xiao Ping's height is 5 centimeters shorter than his brother Xiao Gang. It looked like the two of them were a year apart.
That's because the pure milk that Xiao Gang drank was relatively high in protein, with 3.2 grams of protein per 100 ml, and only 1.2 grams of protein in breakfast milk per 100 ml, which was two grams less protein.
The calcium of pure milk is also higher than that of breakfast milk.
The two important nutrients for a child's height growth are protein and calcium.
Over time, the calcium and protein of pure milk that Xiao Gang drank every day were higher than Xiao Ping's, and the nutrition that naturally grew taller was more sufficient, and Xiao Gang grew taller.
Gap three: differences in vision
Xiao Gang's vision can reach 1.5, while Xiaoping's vision can only reach 1.2, children often eat sugar, it will indeed consume B vitamins, affecting the child's vision health.
Therefore, it is best for children to drink pure milk or low-sugar yogurt, and it is not recommended to drink some breakfast milk with low nutritional value, and it is not recommended to drink various yogurt drinks.
