Fats and Oil  – Obesity in the pipeline

Where did all the fats and oils go?

Experts tell us that fats and oil make it more difficult for our bodies to  digest, While our body system searches and drills for the nutrients and vitamins it needs to keep the body running, it more likely runs into much unneeded oils and grease.

Your Body Is Forced to Work Harder Than It Needs To

Obesity may soon overtake smoking as the number one preventable cause of death.

More than 80% of people diagnosed with type II diabetes – which is preventable and reversible – are overweight or obese.

Obesity increases your risk for…

      • High blood pressure
      • High “bad” (LDL) cholesterol and triglycerides
      • Heart disease and stroke
      • Gall bladder disease and gallstones
      • Kidney stones
      • Fatty liver
      • Osteoarthritis
      • Gout
      • Type 2 diabetes
      • Cancer
 Excessive dietary omega-6 may increase our appetite and promote weight gain.

A recent study suggests a close association between dietary omega-6 and the development of overweight and obesity. Omega-6 is a type of fat found in certain vegetable oils which is present in large amount in processed and junk food.

New results from experiments using animal models show that a high intake of omega-6 led to overproduction of signalling compounds that stimulate the appetite, with the result that the animals ate more and developed obesity.

“People in the Western world are eating less and less fat, but at the same time our body weight is increasing, so the type of fats we eat would seem to mean more for developing overweight and obesity than just how much fat we consume,” says NIFES scientist Anita Røyneberg Alvheim.

Increase in consumption of vegetable oils

In the course of the past few decades, the consumption of vegetable oils has increased dramatically, while our total consumption of fat has gone down. Meanwhile the number of overweight people has drastically risen.

“Our results suggest that there are good grounds for looking into whether the rise in use of omega-6-rich vegetable oils, such as soya, maize and sunflower oil, could be a contributory cause to the development of overweight and obesity ,” says Alvheim.

In the course of the cooperative research project, which is a collaborative effort with scientists in the USA, she used mice to study how different levels of polyunsaturated fat consumption affect appetite and fat storage.

In the study, two groups of mice were given different amounts of linoleic acid, a polyunsaturated omega-6 fatty acid that makes up a large percentage of soya oil, maiz oil and sunflower oil.

A third group was put on a diet with a high content of omega-6 that also contained a certain amount of marine omega-3.

The results showed that the group given the diet with the highest proportion of omega-6, in line with current human recommendations, ate more, and gained considerably more weight than the group on the low-omega-6 diet.
