Why do we age?

Getting older, and showing it, and feeling it, involves a buildup of toxic metabolites including reactive oxygen species, a form of free radicals, and AGEs (Advanced Glycation Endproducts). AGEs are harmful substances that form when protein or fat combine with sugar in the bloodstream. AGEs are implicated in diabetic complications, atherosclerosis, Alzheimer’s disease and normal aging. Having excess body fat makes us age faster.

How do we slow the aging process?

One well established way to slow aging is moderate caloric restriction. This means eating slightly less than your caloric needs. This is not anorexia or fasting, it is known in Japan as Hara hachi bun me. A  Japanese proverb states “eight parts of a full stomach sustain the man; the other two sustain the doctor”. Eating slightly less than we need lowers our temperature a little and slows our metabolic rate.

Many plant foods provide protective substances that can reduce the formation of AGEs. A few examples are garlic, tomato paste, peanuts, green tea, mustard greens, and the isoflavones in soyfoods. In fact the wide range of colourful vegetables and fruits provide us with an army of protective phytochemicals—found only in plant foods.

Certain proteins in our bodies are linked with aging and with cancer. There is a seesaw relationship between these proteins and so called “longevity proteins” such as AMP Kinase. We now have some insights into how to  elevate these longevity proteins. Our best bets are moderate caloric restriction, high exposure to phytochemicals, and exercise. Greens have a particular type of phytochemicals that slow aging–especially cruciferous vegetables: kale, cabbage, baby bok choy, watercress, and arugula. These lifestyle choices help to lengthen our telomeres.

Would you like to prevent type 2 diabetes, cardiovascular disease, cancer, and dementia? We need nutritional excellence, with all the essential protein (preferably from plant foods), minerals, and vitamins present. We need a diet rich in protective phytochemicals and antioxidants that can vanquish free radicals. Plus—it had better taste good! Nutritional excellence is a hundred times more therapeutic than drugs.

A tablespoon of oil just adds 120 calories without much nutritional benefit. Instead, try this nutritious Lemon Tahini Dressing on salads, steamed greens and broccoli, and baked potatoes! Use 1/2 cup each of tahini sesame seed butter) and water; plus 1/4 cup each of lemon or lime juice and of tamari or soy sauce; plus 2 cloves of garlic, chopped. Put everything in a blender and process for 30 seconds or until smooth.

Moderate exercise has beneficial effects on a cellular level. With activity we increase longevity proteins and preserve bone mass. The greater oxygen demand strengthens the heart, lungs, and muscles, making them more efficient. It helps blood flow to the brain. Too much exercise can be negative and a stress; moderate activity is just fine.

Avoid exposure to toxins (including glyphosate/Roundup) and alcohol.

Follow your doctor’s guidance, of course—but don’t simply treat disease symptoms or be satisfied with drugs as your major intervention. Get healthy instead! The result? You will get a longer lifespan, and one filled with abundant health and time to play and enjoy life.
