Research Roundup: July 2020
• Midlife Weight Gain Harms Lungs. Putting on weight during middle age may lead to a decline in lung function, according to researchers in Spain. The weight, height, and lung function of 3,700 adults, aged 20 to 44 at the outset of the study, were tracked three times over a 20-year period, from 1992 to 2014. Those who gained either moderate or high weight experienced a rapid decline in lung capacity, but those who lost weight or maintained a healthy weight throughout, experienced a slower decline. The negative effects of overweight or obesity can be reversed, even later in life.

• Fruits and Veg Tame Menopause Symptoms. Higher intakes of certain fruits and vegetables may lessen menopausal symptoms, like hot flashes and poor sleep, according to researchers. Previous studies have shown the benefits of diet, such as the Mediterranean diet, high in fruits, vegetables, whole grains, and nuts, on menopausal symptoms, while this study found that higher overall fruit and veg intake improved symptoms, but subgroups had mixed results.

• Olive Oil May Boost Heart Health. Consuming more than half a tablespoon of olive oil each day may lower risk of cardiovascular disease (CVD) and coronary heart disease (CHD), according to researchers. The 30-year study included over 63,000 women and 35,000 men who answered diet and lifestyle questionnaires every four years. Over half a tablespoon of olive oil was linked to a 15 percent lower risk of CVD and 21 percent lower risk of CHD. In addition, replacing one teaspoon of alternative fat like butter, margarine, or dairy fat with the same amount of olive oil was associated with 5 percent lower risk of CVD and 7 percent lower risk of CHD.
