Fruits, veggies cut obesity risk in teens

Boston University School of Medicine (BUSM) researchers have found that Dietary Approach to Stop Hypertension (DASH) diet reduces obesity risk in adolescent girls. 

DASH diet emphasizes increased intake of low-fat dairy products, fish, chicken, and lean meats, and nuts, fruits, whole grains, vegetables, and legumes. They found girls who followed the DASH diet pattern had a lower incidence of excess weight gain as measured by body mass index (BMI) over the 10-year period of their adolescence. 

The researchers, led by Jonathan Berz, an assistant professor of medicine at BUSM, used data from the National Growth and Health Study to examine the effects of adherence to a DASH-style eating plan and its components on the change in (BMI) in a racially diverse sample of adolescent girls. 


The study enrolled 2,379 girls aged nine and 10 years in three cities starting in 1987 to 1988 who were followed for the next 10 years. "We created a modified DASH food-group score and focused on the seven DASH-related food groups," said Berz. 

"We found that study participants with the highest intake of DASH-like food groups had the smallest gains in BMI over time and the lowest BMIs at the end of follow-up, and those with the lowest DASH food pattern score (representing lowest adherence) had a mean BMI that was greater than the threshold for overweight as defined by the 85th percentile by age," he said. 
These findings were reported in the Archives of Pediatrics  Adolescent Medicine.

Thyroid - Hypothyroid - Meaning - Causes - Symptoms - Treatment

What is Hypothyroid? Hypothyroidism is a condition in which the body lacks sufficient thyroid hormone. Since the main purpose of thyroid hormone is to "run the body's metabolism," it is understandable that people with this condition will have symptoms associated with a slow metabolism. Causes About three percent of the general population is hypothyroidic. Factors such as iodine deficiency or exposure to Iodine can increase that risk. There are a number of causes for hypothyroidism. Iodine deficiency is the most common cause of hypothyroidism worldwide. In iodine-replete individuals hypothyroidism is generally caused by Hashimoto's thyroiditis, or otherwise as a result of either an absent thyroid gland or a deficiency in stimulating hormones from the hypothalamus or pituitary.

Warts - Meaning - Causes - Treatment

A wart is generally a small, rough tumor, typically on hands and feet but often other locations, that can resemble a cauliflower or a solid blister.

It is also possible to get warts from using towels or other objects used by an infected person. They typically disappear after a few months but can last for years and can recur. Cause Warts are caused by a virus called human papilloma virus or HPV. There are approximately 130 strains of human papilloma viruses. People with week immune system are at the greater risk of this disease. Will warts go away on their own? Often warts disappear on their own, although it may take many months or even years for the warts to go away. But some warts won't go away on their own. Doctors are not sure why some warts disappear and others do not. Treatment Warts can be remov...

Choking

Choking is the kind of emergency in which the chance of getting the victim to a doctor in time is almost nil. Without immediate help, the person can die, or at least suffer permanent brain damage, within four minutes. That is all the more reason for you to keep your wits about you and familiarise yourself with the skills and techniques that might one day save a life - including your own. Cough it out: If the airway is only partially obstructed, violent coughing and sputtering will generally dislodge the obstructing mass. Perform the Heimlich manoeuvre: If the victim is not getting air, and his/her throat is blocked, don't wait for medical help. Take first-aid steps for choking immediately. Stand behind the victim and wrap your arms around his waist. Place your fist with the thumb side against the victim's abdomen slightly above the navel and below the rib cage. Grasp your fist with your other hand and pull it into the victim's abdomen with a quick upward thrust. Repe...
