No woman should ever severely restrict food during her pregnancy, regardless of how much she weighs when she gets pregnant. All obstetricians recommend that a woman gain at least 20 pounds during her maternity, also if she weighs 300 pounds when she becomes pregnant.
In 1988, David Barker of the University of Southampton in England noticed that in the beginning of the twentieth century, poor areas of England had an extremely high incidence of newborn babies dying and those that survived had a very high incidence of heart attacks later in life. He noticed that babies born to very women that are poor tiny at birth. He concluded that when a mother is deprived of food during her pregnancy, she gives birth to babies who are small at birth, and the ones who survive have reached high-risk for heart attacks many years later if they become adults.
Further research suggests that small newborns from big parents are prone to die in infancy than small babies from small parents. A baby who should have been born at 9 pounds as a result of big parents, but weights only 5 pounds at birth, is the one most prone to perish and start to become sickly. A five pound baby whose parents were small was supposed to be about five pounds. So babies that are tiny because they are deprived of food within the womb would be the ones most prone to perish in infancy and suffer heart attacks later in life.
Then study from the Amsterdam famine of 1942 revealed that babies who're deprived of food in the 1st three months of pregnancy are the ones most likely to suffer heart attacks as adults. However, study from the Stalingrad famine of 1942 showed that babies deprived of food in the uterus who usually do not be fat later in life are maybe not at increased risk for heart attacks later on. The Amsterdam babies had lots of food throughout their childhoods, while the Stalingrad babies continued to be starved for their whole childhoods because associated with slow recovery associated with Russian economy after World War II. The Amsterdam babies suffered heart attacks as grownups, while the Stalingrad babies failed to.
Studies in the Philippines reveal that depriving a baby of food in the uterus causes him or her to own high blood pressure and raised chlesterol later in life. We've established that when a child is deprived of food in the womb and it is given lots of food later on, he or she is at great risk for a heart attack. On the other hand, if a baby is starved in uterus and is not given lots of food later on, his risk for a heart attack is perhaps not increased. We have now to explain how depriving a baby of food into the womb and overfeeding him during childhood causes heart attacks. There is certainly a body that is huge of showing that starvation in the uterus shunts blood to the brain and away from the other organs, causing an infant become born with small liver, pancreas, kidneys and so forth. These organs do not function as well and when these babies are given too much food later on on, they have actually higher than normal amounts of insulin and other hormones that constrict arteries to cause heart attacks. These babies have smaller kidneys which might not be able to function as well, so when they do not get sufficient oxygen, produce too much renin that additionally constricts arteries to cause high blood pressure. High levels of insulin constrict arteries and cause heart attacks.
Therefore all women should gain at the very least 20 pounds once they are pregnant. If unborn babies aren't getting enough calories in the uterus, they shunt each of their calories to the brain and far from other organs in their bodies. They have actually little livers and kidneys. Small livers cannot remove insulin after meals, causing high insulin levels that constrict arteries and cause heart assaults. Small kidneys discharge chemicals to the bloodstream that constrict arteries to cause high blood pressure, and strokes.
