Risks of eating too much cabbage
The nutritionist Gabriel Cairo, an expert on the physiology of weight loss, explains that the cabbage contains a substance called pro-goitrina. In the human body, it turns goitrina, that, yes, able to reduce the release of hormones by the thyroid gland. Cabbage also contains thiocyanate, a substance which competes with iodine in the body and decreases the absorption of mineral important for the health of the gland.
thinkstockA thyroid produces hormones that are closely related to the metabolism.
According to the expert, the cabbage cause hypothyroidism if consumed in very large quantities and science still knows little about the relationship of cause and effect. There are two studies with opposite results have generated great discussion. The first, published in the journal Human & experimental toxicology, assessed the impact on the thyroid caused by daily consumption of 150 sprouts Brussel cooked for 4 weeks, the researchers found no change in the release of hormones by the gland (Remember, the cabbage cooking seems to be able to decrease the action of chemicals that act on the thyroid and this may be the reason why changes were not found). Another American study, published in The New England Journal of Medicine reported the case of a lady of 88 years who ate daily 1 kg to 1.5 kg of cabbage in order to improve their diabetes above and after months of excessive consumption, it triggered an acute hypothyroidism and coma.
Cabbage is rich in fiber, which means that it is a long time in your digestive system and give you satiety. Another benefit of the large amount component is decreased absorption of sugar and fat to a little. On the other hand, consume plenty of fiber without taking good amounts of water can cause constipation. This is because the absence of the liquid hinders the slip of stool through the digestive tract.
By tracking urine tests of one of her patients, the molecular biologist Ernie Hubbard found very large amounts of thallium, a toxic mineral that can cause fatigue and lack of concentration. After eliminating other possible causes, he came to the conclusion that it was the cabbage that was causing the problem. According to their findings, the plant would be able to store large amounts of this mineral, which typically is in the ground. The story gained wide media coverage, but science has not proved this relationship between cabbage and poisoning by thallium.
How to eat cabbage in the right way
Amount that can eat
thinkstockComer fibers is very good, but you need to take enough water to balance them in the body.
Cairo explains that cases of hypothyroidism for cabbage consumption are rare and even people who already have the disease hardly have problems if consumed moderately cabbage. His recommendation is to eat up to 5 pages per day, totally safe measure.
In the case of digestion, the recommendation is to eat 25 grams of fiber per day. But to ensure that this nutrient flow well into your body, the displayed is to drink about 2 liters of water a day - varying according to the body weight, physical activity and other factors.
For dieters care is even greater. "When you do a diet, the trend is that the amount of food decreased. Without consuming the same amount of water from food, it is essential to drink more water"Explains Cairo.
Eat cabbage all day is bad?
If you eat moderate amounts of cabbage, probably will not have problems. However, the nutritionist explains that you'll be eating every day the same nutrients. "Ideally interim consumption of sprouts and cabbage, lettuce, chicory, arugula, Catalonia and other leafy vegetables"He explains. This way, you will consume a greater variety of nutrients.
raw cabbage can?
Raw cabbage keeps active substances that act on the thyroid and therefore more care is necessary not to exaggerate consumption. The green juice, which leads cabbage, further deserves attention. That's because the drink you consume more amounts of the sheet and therefore more pro-goitrina and thiocyanate.
