(CBS) - The widespread rejection of estrogen therapy during the last decade may have led to nearly 50,000 unnecessary deaths.
That's the conclusion of Yale researchers. Hormone replacement therapy fell out of favor after a 2002 federally funded study found that it led to an increase in breast cancer, heart disease and stroke.
But Yale researchers say estrogen only therapy can save lives for post-menopausal women who have had hysterectomies.
They say the danger was for women who still had their uteruses who took estrogen combined with another hormone.
(CBS) - New findings suggest that breaking a sweat may lower the risk of having a stroke.
Researchers looked at more than 27,000 participants and found those who did not exercise were 20 percent more likely to experience a stroke compared to participants who exercised four or more times a week.
The study found that participants had to engage in moderately vigorous exercise, which is enough to break a sweat, to receive the benefit.
(CBS) - Putting information on calorie intake on menus may not help consumers make better food choices.
Researchers at Carnegie Mellon University divided more than a thousand diners into three categories – those who were told how many calories they should eat per day, those who were told how many calories they should eat per meal and those who were given no guidance.
They found no difference in the food selections between the three groups even though they knew the calorie content of the items on the menu.
The researchers conclude it may be unrealistic to expect people to count calories.
