Hey kids: If you want to slow down your aging process, lengthen your telomeres! How do you do that? Telomeres are the protective caps on the ends of chromosomes that affect how quickly cells age. As they become shorter, their structural integrity weakens, which causes cells to age and die younger. In recent studies, shorter telomeres have become associated with a broad range of aging-related diseases, including cancer, stroke, obesity, diabetes, vascular dementia, cardiovascular disease and osteoporosis.

Recently, a significant link between irisin levels in the blood and telomere length has been discovered. Irisin is a hormone released from muscle cells after endurance exercise and it extends your telomere length! People who have higher irisin levels are “biologically younger” than those with lower levels of the hormone. Not only that, irisin reprograms the body’s fat cells to burn energy instead of storing it.

When irisin levels rise through aerobic exercise, the hormone switches on genes that convert white fat into “good” brown fat. This is beneficial because brown fat burns off more calories beyond just the energy used to do the actual aerobic exercise. This helps you maintain a healthy BMI, avoid obesity and conditions like type-2 diabetes. In addition, irisin stimulates the growth of neurons and improves cognition!

So, how do you up your irisin? Eat plenty of citrus, berries, carrots, tomatoes, nuts and whole grains. Then, take a ride on your bike or a brisk walk. Irisin levels increase with regular aerobic exercise like biking or swimming, but not during short-term bursts of anaerobic muscle activity, like yoga. Exercise is already known to have wide-ranging benefits, from cardiovascular protection to weight loss. Now, there is a molecular link between keeping active and a healthy aging process.

Oh, and while you’re at it, toss a little choline into your diet. It reduces levels of homocysteine, an amino acid that acts as a neurotoxin and contributes to Alzheimer’s by forming amyloid plaques in your brain. It also causes inflammation and can lead to neuronal death. Eggs, liver, peanuts, meats and dairy foods will up your choline in no time!
