Babies who are breast-fed seem to be less likely to develop type 2 diabetes as adolescents, according to University of South Carolina researchers.

Using a subset of data from a larger study, the researchers analyzed 80 people between the ages of 10 and 21 with type 2 diabetes, who were matched with 167 “controls” who did not have diabetes.

The breastfeeding rate was lower among people with type 2 diabetes, compared with the control group. Specifically:

* Among African Americans, only 20 percent of those with type 2 diabetes had been breastfed, compared to 27 percent in the control group.
*Among Hispanics, 50 percent of the diabetes group was breastfed, compared with 84 percent of the control group.
*Among whites, 39 percent of the diabetes group was breastfed, compared with 78 percent of the control group.

The researchers concluded that breastfeeding in itself had a protective effect against type 2 diabetes. It also helped to stave off the disease because it helped to moderate childhood weights.

Encouraging breastfeeding in groups at high risk of type 2 diabetes may be useful, the researchers said.

To Be Healthy, Work Up a Sweat

To be healthy, you really do need to break into a sweat when you exercise, say experts.

Official advice that 30 minutes of gentle exercise a day is enough to improve your health has been revised by the scientists who first developed the international fitness guidelines. Members of the American College of Sports Medicine are concerned the advice is being misconstrued.

Some may take this to include a mere stroll to the car. People should do at least 30 minutes of moderate exercise five days a week, or 20 minutes of vigorous exercise, like jogging, three days a week, they say.

There is confusion about what is the ideal amount and intensity of exercise to improve health. All agree that regular exercise is essential. The World Health Organisation (WHO) has said 30 minutes of gentle exercise each day could be enough to sustain a minimum level of fitness.

Recently, researchers at Queen’s University, Belfast, found walking for half an hour on just three days a week gave similar fitness and blood pressure benefits to walking for 30 minutes five times a week.

The sports scientists, however, say this advice is misleading and could encourage people to do too little exercise. “There are people who have not accepted, and others who have misinterpreted, the original recommendation.

Some people continue to believe that only vigorous intensity activity will improve health, while others believe that the light activities of their daily lives are sufficient to promote health,” they told Circulation , the journal of the American Heart Association.

Their original recommendations in 1995 were quickly adopted by the WHO. They now stress that adults need to top up their routine activities, such as casual walking and housework, with structured exercise.

This should include vigorous (jogging) and moderate aerobic exercise (a brisk walk), as well as twice-weekly activities, such as weight training, which maintain or increase muscular strength and endurance.

People can do short bouts of exercise to count towards their weekly goals, but these must last for at least 10 minutes. They say that even more exercise than this may have further benefits.

However, research has also shown that too much exercise can be damaging to the body. Professor Paul Gately, professor of exercise and obesity at Leeds Metropolitan University, told The Guardian that it was difficult to give ‘one-size-fits-all’ advice.

“People who are very overweight would have to do an hour of exercise a day just to maintain their weight if they aren’t going to change their diets,” he said.

Why do you need calcium?

Calcium is the most common mineral in the human body. Calcium is essential to the growth and maintenance of strong, healthy teeth and bones. It is also necessary for regulating the heartbeat and lowering cholesterol levels.

What are some good sources of calcium?

Dairy products and vegetables are the main sources of calcium; meat, fish, eggs, cereal products, beans, and fruits can also be good sources.

What can happen if we don’t get enough calcium?

Aching joints, dry, brittle nails, tooth decay, high blood pressure/high cholesterol levels in the blood, and muscle cramps have all been associated with calcium deficiencies. Perhaps the most significant potential complication from inadequate calcium intake is bone loss, often leading to osteoporosis and increasing the risk for one fractures.
