Water intake helps reduce diabetes risk
There are many reasons why people should drink water in the recommended amounts. A new study, the largest of its kind published in the journal Diabetes Care, has shown that it also helps to reduce the risk of diabetes.
The amount of water ingested is related to the regulation of blood sugar levels. A hormone called vasopressin, whose function is to prevent dehydration and maintain adequate levels of electrolytes - such as sodium and potassium - increases when the body is receiving little water. This hormone, in excess, leads to increased production of glucose in the liver, which in the long run changes production and response to insulin.
French researchers recruited participants for the study at nine health centers in France, such as the Université Paris-Diderot and the Département d'Endocrinologie , all in Paris. More than 3,000 healthy men and women between the ages of 30 and 65 have been followed for almost a decade.
After nine years, about 800 had developed type 2 diabetes, but those who consumed large amounts of water had about a 30% lower risk of developing the disease. Factors that could interfere with outcomes such as intake of other liquids - soft drinks and alcohol -, exercise, and weight were controlled.
Researchers point out that drinking adequate amounts of water may help prevent diabetes. In addition, other associated factors must also be controlled, such as healthy eating and obesity control.
Ask your questions about diabetes
In Brazil, about seven million people, over 18, have the disease. A recent study by the Brazilian Society of Diabetes shows that more than 60% of them do not know they have the disease.
The diabetic can consume honey, brown sugar and sugarcane juice without problems?
Although natural, these foods have sucrose sugar, the biggest villain of diabetics. "The diabetic can even consume it, but he must be aware that he can not abuse and compensate with a balanced diet," explains nutritionist Patrícia Ramos, coordinator of Bandeirantes Hospital (São Paulo).
Some foods help control levels of blood glucose assisting in the treatment of diabetes?
Yes. This is due to the Glycemic Index (GI) of food. When a food has low glycemic index, it slows the absorption of glucose by the blood and therefore stabilizes the disease. But when the rate is high, this absorption is rapid and speeds up the increase in blood glucose levels.
Insulin application causes chemical dependence?
Insulin application does not promote any kind of chemical or psychic dependence . The hormone is important to allow the entry of glucose into the cell, making it a source of energy.
Can it prevent insulin if you do not ingest carbohydrates?
It depends. Carbohydrate raises blood glucose faster, so your intake should be controlled. "In type 1 diabetes, insulin is required daily, since the pancreas does not produce this hormone, so even if you do not eat carbohydrates, you need to apply insulin. If you are under control, you can stop using it, but only a doctor can do this evaluation, "explains Patricia.
Who has diabetes should only do light exercise?
That's right. Diabetics should be encouraged to do physical activities, respecting contraindications, if any. "In general, exercise improves glycemic levels, but when caloric expenditure is greater than the replacement of nutrients after training, there may be hypoglycemia," says the nutritionist.
According to the results, men and women smokers who completed 12 weeks of resistance training as part of a smoking cessation program are twice as likely to quit compared with those who do not regularly lift weights. To reach this conclusion, we analyzed 25 men and women between 18 and 65 years old who reported smoking at least five cigarettes a day.
The Ministry of Health investigates 3,448 suspected cases of microcephaly all over the country. The new bulletin released on Wednesday (27) points out that up to now 270 cases have already been confirmed microcephaly, 6 in relation to the Zika virus. Another 462 reported cases have been discarded. In all, 4,180 suspected cases of microcephaly were recorded by January 23.
