Starting Healthy Habits Later In Life Still Makes A Difference
Written by Kathryn Savage
We know that diet and exercise play a vital role in living a long, healthy life, and scientists are always coming up with new information that helps explain why this is.
A recent study, (July, 2007), published in the journal Science, reveals that even if we start later in life, healthy lifestyle habits, (eating lots of fruits, vegetables, whole grains and a diet low in saturated fat, along with exercise), has a profoundly balancing effect on our hormones. This may extend more than our ability to rock those skinny jeans, it also extends the health of our brains.
Quoted in a CBS News report, researcher Morris White, PhD, who works at the Children's Hospital Boston and Harvard Medical School, explains that adopting healthy habits "...has less to do with how we look, and more to do with a healthy brain, especially in old age.”
Researcher Morris White, PhD and others, focused their attention on the Irs2 gene in mice. This gene is responsible for creating a protein that helps cells absorb insulin, a hormone that monitors blood sugar levels. What the scientists found in mice, is a link between an inactive Irs2 gene and insulin insensitivity. The mice with insulin insensitivity gained weight and became inactive. Insulin resistance, or insensitivity in people often leads to metabolic syndrome and type 2 diabetes. According to a report released by the Mayo Clinic, diabetes increases your risk for Alzheimer's.
A healthy diet and exercise naturally balances blood sugar and keeps hormones in line. This isn’t about playing with genes, and getting all mad-scientist on some mice, our altering our brain chemistry to promote longevity through pills and potions. It’s more about promoting tried and true habits, and encouraging the body to take care of itself naturally. Daily exercise, calorie restriction, and maintaining a healthy weight all contribute to insulin sensitivity, reducing your risk for diabetes and possibly Alzheimer's.
