...their patients' experience - and by concerns about health over vanity. By a doctor's standard, even a 5% to 10% reduction in body weight can make a big difference to a patient's health. On that level, at least, there's little doubt anti-obesity medications can help. The BMJ (formerly the British Medical Journal) paper, a comprehensive review of 30 controlled trials on anti-obesity drugs, showed unambiguously that orlistat (Xenical), sibutramine (Meridia) and rimonabant (Acomplia) all resulted in weight loss - but the drugs' benefits extended beyond that. In one four-year trial, orlistat reduced the incidence of type...
...kids are smarter, taller, thinner, healthier and less stressed than babies on bottles. Plus, breast-feeding helps moms bond with their babies and may even lower their blood pressure. So, is there anything breast milk can't do? Apparently, yes, according to a new study published Tuesday by BMJ Online: It doesn't offer infants much defense against asthma or allergies...
...Until now, the evidence has been mixed: Some studies have suggested that exclusive, prolonged breast-feeding helps stave off asthma and allergies later in life; other studies have shown no protection, or even an increased risk. But most of the available data has come from observational studies. The new BMJ paper, in contrast, was a large, long-term randomized trial that involved more than 17,000 breast-feeding women and babies, 13,889 of whom were tracked until age 6 1/2. Researchers recruited the moms in maternity hospitals and clinics in Belarus. About half of them - those who had already...
...BMJ study is "to our knowledge.. the largest randomized trial ever done in the area of human lactation," write the study's authors. But it's not likely to be the last. Science will continue to debate the discrete pros and cons of breast-feeding, but doctors unanimously agree that breast, in general, is best for babies' health, growth and development. Mothers should breast-feed newborns for at least 12 months - and exclusively for at least 6 months - according to American Academy of Pediatrics guidelines...
Which one was right? Probably neither, since both studies were flawed. The J.A.M.A. study included subjects who were on low-salt diets for a very short time--perhaps too short for any effect to be noticed. And the BMJ study could not effectively measure the influence of other factors that could have made a difference. Those who ate less salt may also have watched what they ate in general, for example, exercised more or been less overweight...
