Can Excess Intake of Niacin Vitamin Cause Obesity

Chinese researchers found that excess intake of Niacin vitamin is may be a risk factor for obesity. The results of a recent study were published in the May 21st, 2010 edition of the World Journal of Gastroenterology. This research has special implications in the recent times as there are very few research studies done on the relation between obesity and vitamin intake worldwide.

How Niacin Vitamin Excess Consumption Causes Obesity?

Dietary factors were always known to be closely related to the development of obesity. The epidemic increase of this disorder in recent times raises the concern that the average diet is no longer a healthful and life supporting one. A possibly neglected aspect of the average diet today is over consumption of foods rich in niacin. Effects of the long term exposure to niacin are still not known.

In the present study the researchers wanted to find the influence of excess niacin consumption in the metabolism of glucose. They learnt that when the levels of this vitamin increase in the blood, it causes insulin resistance in the initial stages and later lead to a hypoglycemic state in the body. This development can be the main reason for a raise in overall appetite. Over consumption of calories in the form of food is the main cause of obesity, along with lack of physical activity.

The study also found that many grain products have this vitamin added to in them at higher levels. Consumption of these food items by adults and children in the United States and raise in obesity rates took place simultaneously in the last 10 years.

Is There a Way Out ?

Researchers believe that elimination of excess niacin from the body through sweat by physical activities can be highly beneficial in preventing and treating the physical disorder of obesity in our society. As with any lifestyle, physical activity is recommended and loss of excess niacin from the body is an added benefit in this aspect.

Further research on this topic is under-way and with gaining of more insights, the role of excess intake of this vitamin in obesity will be becoming even clearer.
