New research: cut back on carbs, live longer

According to the 2002 United States Life Tables, In 2002 the average person in the US could expect to live a little over 19 years longer than in 1920. But does longevity come with a healthy life? Not for most. Arthritis, Alzheimer’s, cardiovascular disease, deteriorating senses, and other diseases and conditions all come with age. However, new research may have uncovered a true fountain of youth, and it may be as simple as cutting down on consuming carbs.

Professor Cynthia Kenyon, a US genetisist, has discovered that the carbohydrates we eat like bananas, potatoes, bread, pasta, and cakes directly affect two key genes that govern youthfulness and longevity.

But what Professor Kenyon found out was why ­drastically reducing calories has such a remarkable effect.

She discovered that it changed the way two crucial genes behaved. It turned down the gene that controls insulin, which in turn switched on another gene, which acted like an elixir of life.

‘We jokingly called the first gene the Grim Reaper because when it’s switched on, the lifespan is fairly short,’ she explains.

The ­second ‘elixir’ gene seems to bring all the anti-aging benefits.

Professor Kenyon has changed her diet as a result of her research.

‘Carbo­hydrates, and especially refined ones like sugar, make you produce lots of extra insulin. I’ve been keeping my intake really low ever since I discovered this.

‘I’ve cut out all starch such as potatoes, noodles, rice, bread and pasta. Instead I have salads, but no sweet dressing, lots of olive oil and nuts, tons of green vegetables along with cheese, chicken and eggs.

‘I’ll have a hamburger without a bun and fish without batter or chips. I eat some fruit every day, but not too much and almost no processed food. I stay away from sweets, except 80 per cent chocolate.’

She is adamant it will be well worthwhile. ‘You could have two completely different careers if you could stay healthy to 90,’ she says. ‘How fascinating that would be.’

The benefits of pre-breakfast exercise

The holidays always spell WEIGHT GAIN for most. However, there may be a way to lessen the blow of higher holiday calories. A study published in The Journal of Physiology for the first time shows that fasted training in the morning is more potent than training after breakfast to facilitate adaptations in muscle and to improve whole-body glucose tolerance and insulin sensitivity during a high-fat hyper-caloric diet.

The holiday season brings many joys and, unfortunately, many countervailing dietary pitfalls. Even the fittest and most disciplined of us can succumb, indulging in more fat and calories than at any other time of the year. The health consequences, if the behavior is unchecked, can be swift and worrying. A recent study by scientists in Australia found that after only three days, an extremely high-fat, high-calorie diet can lead to increased blood sugar and insulin resistance, potentially increasing the risk for Type 2 diabetes. Waistlines also can expand at this time of year, prompting self-recrimination and unrealistic New Year’s resolutions.

But a new study published in The Journal of Physiology suggests a more reliable and far simpler response. Run or bicycle before breakfast. Exercising in the morning, before eating, the study results show, seems to significantly lessen the ill effects of holiday Bacchanalias.

Jack Lalanne – Treat your body like you should

Suppose somebody gave you an automobile the would repair itself, but there were a few simple rules you had to follow. One, you had to drive the car a half an hour a day. Two, you had to use the best fuel possible. Do you think you would follow those rules to have the only car that repaired itself? Of course you would. Jack Lalanne poses the question, “then why don’t you treat your body as well as an automobile that repairs itself?”

More good news for saturated fat

A meta-analysis published in the American Journal of Clinical Nutrition (March 2010 9(3)535-546), combined the relative risk rates of cardiovascular disease (CVD) from 21 studies. This Mega-analysis represents almost 350,000 subjects whose diets and health outcomes had been followed for 5 to 23 years. The conclusion: “There is no significant evidence concluding that saturated fat is associated with an increased risk of CVD.
