A new long term study on calorie restriction in primates reveals that while cutting calories might not extend life, it reduces the incidence of degenerative diseases like cancer and diabetes. These results appear to contradict the conclusions of a 2009 study that showed longer survival rates for monkeys on calorie restriction.
For decades in many studies, mice fed a diet with a third fewer calories, lived an average of about a third longer. The new study tracked 121 rhesus monkeys at the National Institutes of Health from 1987 on comparing one group placed on 30 percent calorie restriction with another that was allowed to eat the same food, but without restrictions. The study was published in the journal Nature on August 29, 2012.
Since long lived monkeys are far closer biologically to humans than mice, the study has relevance for us. In the anti-aging documentary, “Reverse Aging Now” calorie restriction guru Roy Walford, MD espoused a low calorie, nutrient dense diet as a way to slow biological aging. The only physician in the Biosphere he was in a unique position to test his theories. For two years eight people lived in that self-contained ecosystem in the Arizona desert where due to design flaws the inhabitants couldn’t grow enough food. Walford put the crew on a calorie restricted highly nutritious, primarily vegetarian diet. By his measurements of biological age, looking at common bio markers including blood pressure, cholesterol, and lung capacity, he determined that the crew aged at half speed. The inhabitants were isolated for two years but they aged biologically just one year.
The new monkey study concluded that the calorie restricted monkeys looked younger, weighed less, and had lower cancer risks, while calorie restricted males had lower cholesterol levels too. The senior author of the study, experimental gerontologist Rafael de Cabo, PhD did not dismiss the worth of calorie restriction as an anti-aging strategy. He concluded instead that "we are seeing a separation between what we call 'health span' from 'life span' — they are not hand in hand."
Even if calorie restriction ultimately proves to be less effective in increasing ultimate longevity in primates compared to rodents, the benefits in quality of living make the method worth considering. Remember that it’s not enough to simply cut calories. To produce concrete anti-aging results, make sure that the calories consumed are nutrient rich, favoring legumes over pork rinds.
High cholesterol has long been recognized a risk factor for cardiovascular disease. Most of our cholesterol is not consumed but produced by our own livers from saturated fat, so it’s more important to cut saturated fat, and eliminate trans fat from our diets than to purge our diets of all cholesterol.
Cooked by themselves, eggs are high in protein and low in calories. A single hard boiled egg typically is less than 80 calories with 6 grams of protein and is a good source of riboflavin, vitamin B12 and phosphorus, but the yolks are high in cholesterol. For those of us tempted to abandon egg white omelets and start using more whole eggs in our diet, a new Canadian study of 1262 middle aged patients should give us pause. Thickening of the carotid artery walls was found to proceed linearly with aging, but for those who ate egg yolks the walls thickened more, paralleling to the same results seen in cigarette smokers. For the top 20 percent of egg yolk consumers, the narrowing was about 2/3 that of heavy smokers.
The study was published in the August 10, 2012 edition of the journal Arteriosclerosis. The study’s authors urge that people at risk for heart disease eliminate egg yolks from their diets. The National Heart Blood and Lung Institute suggests that all of us limit our cholesterol intake to no more than 300 mg per day, about that found in 1 ˝ egg yolks and eat no more than four whole eggs weekly, including those in baked goods.
Apple skins are surprising effective in fighting high blood pressure, according to a new Canadian study published in the journal Food Chemistry. Apples have long been recognized as having health properties. Pectin, the soluble fiber found in both the pulp and the skin, has been found to reduce bad cholesterol.
Now researchers at Nova Scotia Agricultural College have analyzed the compounds in apple skins and pulps separately and have learned that the peel can be up to six times more effective than the rest of the fruit in inhibiting an enzyme called ACE, which contributes to hypertension. This places apple skins in the pantheon of Super foods explored in the anti-aging documentary “Reverse Aging Now” as well is in this free YouTube video.
High blood pressure is called the silent killer because it can produce strokes or heart attacks without any overt advanced signs. Diet and exercise are the first steps to take in fighting hypertension. Adding the proverbial apple a day is a now good step to embrace as well. Since pesticide residues tend to linger on the skin, it’s a good idea to clean apples thoroughly before eating them whole. Even better, eat organically grown apples.
For many grilling is a big part of summer. Kebabs cook quickly, and are fun and easy to make. This recipe increases your consumption of vegetables and lowers your fat intake compared to cooking steak.
• 1/4 cup olive oil
• 4 tablespoons soy sauce
• 2 tablespoons Worcestershire sauce
• 1/4 cup of red wine vinegar
• 1 tablespoon of lemon juice
• 1-1/2 teaspoons dry mustard
• 1 teaspoon black pepper
• 1/2 teaspoon finely ground parsley
• 4 ounces of lean chicken per person
• Vegetables / fruits including red peppers, red onions, zucchini, cherry tomatoes and apples
At least a half hour before you put the kebabs on the grill, mix the liquid marinade ingredients in a bowl, then add the dried spices. Cut lean boneless chicken breasts into 1 ½- 2 inch cubes and soak in the bowl, rotating.
Skewers are either bamboo or metal. If you use bamboo, they should be soaked in water while your meat is marinating. Coat your skewers with cooking spray just prior to using so the meat doesn’t stick.
Cut your vegetable into slices. You can keep the cherry tomatoes whole.
When you’re ready to grill, spear meat and vegetables alternating them, coating vegetables with a light brushing of marinade. Be sure to rotate skewers as they cook, and leave space on the grill for air to circulate. Do not overcook the meat to minimize formation of potentially dangerous heterocyclic amines. Enjoy this last taste of summer.
