A cornerstone of dietary advice has long been to replace saturated fat with polyunsaturated fat to reduce risk of heart disease. This is advice that has been challenged in the past few years, however. Health writers and some nutrition experts have questioned whether saturated fat is to blame for heart disease or whether other dietary components are the culprits. Suddenly, bacon and steak have become the new health foods….
Soyfoods are without effect on the age of onset of menarche
In many countries throughout the world, the age at which puberty occurs among girls—manifested as breast development, appearance of pubic hair, and onset of menarche—has been commencing earlier. For example, the mean age at onset of menarche (AOM) in Korea decreased from 16.9 to 13.8 years between 1920 and 1985. In the United Kingdom, between 1910 and 1993, it decreased from 13.5 to 12.3 years. And in the United States the AOM decreased by an average of 3 to 5½ months from 1960 to 1990….
Soyfoods lower risk of ovarian cancer
The American Cancer Society estimates that in 2014, about 21,980 American women will be diagnosed with ovarian cancer and about 14,270 women will die from this disease. Ovarian cancer ranks fifth in cancer deaths among women, accounting for more deaths than any other cancer of the female reproductive system. A woman’s risk of getting ovarian cancer during her lifetime is about 1 in 72. Her lifetime chance of dying from ovarian cancer is about 1 in 100….
Plant-based diets and soy lower blood pressure
As many as 67 million American adults, or about one in three adults, have high blood pressure and just as many have prehypertension—blood pressure numbers that are higher than normal—but not yet in the high blood pressure range. Elevated blood pressure increases risk for heart disease and stroke and is a contributing factor in nearly 1,000 deaths per day in the United States….
Soy Infant Formula Given a Clean Bill of Health
First introduced almost 100 years ago, soy infant formula has been in widespread use since the 1960s. It has been estimated that more than 20 million Americans consumed soy infant formula as babies. Despite this long history of use, questions about the safety of soy infant formula have arisen. They are based largely on the high isoflavone content of soybeans….
Although elevated cholesterol levels are most closely associated with heart disease, there is also evidence that they could raise risk for breast cancer. According to researchers from Duke University Medical School and several other institutions, a metabolite of cholesterol called 27HC turns into a potent estrogen-like molecule that could affect risk of breast cancer. Therefore, it is possible that approaches to lowering blood cholesterol may help to prevent and treat breast cancer. Consuming more soyfoods may be one of those effective approaches.…
About 20 percent of people who travel to the Rocky Mountains or other peaks over 8,000 feet experience acute altitude sickness. It’s due to oxygen deprivation and results in headache, loss of appetite, and trouble sleeping. Altitude sickness occurs most often when people travel quickly from lower altitudes to higher altitudes. It has nothing to do with fitness levels, and both men and women are equally likely to suffer from altitude sickness.…
