Omega Imbalance: Know Your Fats!

PARIS (AFP) – Overeating combined with the wrong mix of fats in one's diet can cause obesity to be carried over from one generation to the next, researchers in France reported Friday.  Omega-6 and omega-3, both polyunsaturated fatty acids, are each critical to good health.

But too much of the first and not enough of the second can lead to overweight offspring, the scientists showed in experiments with mice designed to mirror recent shifts in human diet.  Over the last four decades, the ratio of omega-6 to omega-3 in a typical Western diet has shifted from a healthy five-to-one to 15-to-one in much of Europe, and up to 40-to-one in the United States.  In the breast milk of American women, the average ratio has gone from six-to-one to 18-to-one.

Earlier studies have established a link between such imbalances and heart disease. But "this is the first time that we have shown a trans-generational increase in obesity" linked to omega intake, said Gerard Ailhaud, a biochemist at the University of Nice-Sophia Antipolis and main architect of the study.  "Omega six is like a fat-producing bomb," he told AFP by phone. Experts differ on whether obesity is more importantly due to the percentage of fat in one's diet or the sheer amount of calories consumed.

The findings, published in the US-based Journal of Lipid Research, add yet another dimension to the debate, and could shed new light on the obesity epidemic that has swept across the globe, mainly in rich nations.

They also suggest that persistence within families of health-threatening weight gain -- while not genetic in origin -- may not be entirely due to environmental factors either. The link between omega imbalance and obesity "is probably epigenetic," said Ailhaud, referring to the complex process whereby the information in genes is translated into chemical activity. "The genome and the DNA of the rodents has not been modified, but these factors can influence the way in which certain genes are expressed."

In the experiments, four generations of mice were fed a 35-percent fat diet with the omega imbalance now found in much of the developed world.  The result was progressively fatter mice at birth, generation after generation.  The rodents also developed insulin-resistance, a telltale symptom for diabetes 2, one of the most common -- and debilitating -- consequences of obesity in humans.  The equally undesirable increase in omega-6 and drop in omega-3 can be partly explained by the change from grass-fed to grain-fed livestock, Ailhaud explained.  Grass is rich in omega-3. "But to increase productivity, feed was shifted to grain meal, especially corn, which contains a high concentration of omega-6," he said.  Adding a small quantity of flaxseed oil to animal feed could help restore a healthy omega balance in meat and daily products, he added. 

There are three types of fatty acids -- saturated fats, monounsaturated fats and polyunsaturated fats.

In France, health authorities recommend that fat intake should between 30 and 40 percent of calories consumed, while the US Food and Drug Administration suggests a range of 20-to-30 percent.  Both governments agree that most of that intake should be from polyunsaturated and monosaturated fats such as fish, nuts and vegetable oils rather than the saturated fats found in red meat and dairy products.

Chiropractic Treatment Helps With Blood Pressure

High blood pressure affects millions of Americans; one out of every three. If left untreated, it can be deadly. Most people take medication to control but some patients have found a simple way to keep their numbers down without drugs. They're turning to chiropractic care.

The mad dash to get the kids off to school, the crazy commute and work, they are enough to raise anyone's blood pressure. Just ask Adrian Caspar. "We work on deadlines, and that's what makes it difficult," said the busy accountant. "All the changes in the law keep me in business, but keeps us also pretty stressed out," he added.  Like many people, the stress began to take its toll and Caspar was forced to go on medication for his high blood pressure.

Caspar didn't like the idea of being on medication so he decided to visit chiropractor Dr. Peter Martone. Dr. Martone has been using a new adjustment to the neck to help bring down blood pressure. "If the bone is out of alignment and putting pressure on a nerve, it interferes with the ability of the heart to function properly," Martone explained.  After a few visits, Caspar's blood pressure was normal. Bill Bird also has a stressful job. He's a car salesman. He was also on blood pressure medication but wanted to try to control his numbers naturally. His daughter suggested a visit to Dr. Martone.

A few adjustments later and Bird's primary care physician cut his medication in half.   "Another 30 to 45 days, if my blood pressure stays at this level, I'm going to be off it 100 percent," he said, enthusiastically.  The treatment is experimental, but studies show it might actually work.  "This is a very novel concept," explained blood pressure specialist Dr. George Bakris.  Dr. Bakris conducted a small, carefully controlled study with some of his patients.  He sent them to a chiropractor for the same adjustment Dr. Martone uses.

"We saw miraculous changes in blood pressure," Dr. Bakris explained. The results were dramatic enough to catch the attention of the federal government.  The National Institutes of Health is now funding a study to see if the findings can be duplicated. While Dr. Bakris believes the study is exciting, he admits there are a lot of unanswered questions.

"I think we'd have to really find out what is going on, why this is happening," he said.   Caspar and Bird say they have all the proof they need. "I just feel better and feeling better is the way to be," Caspar said. Bird agreed. "I feel younger. I've never felt better," he said. Dr. Bakris believes this is most likely to work on people who have had some sort of neck trauma in their lives, even if it was falling off a swing as a child.

He believes if your hypertension is hereditary, this may not work for you. The experts also warn that patients should not stop taking their blood pressure medication without talking to their doctor first.
