Vitamin A may protect the heart from some of the effects of obesity
In a study at the Hannover Medical School in Germany, scientists found more damage to heart-related genes combined with vitamin A deficiency.
The findings suggest that vitamin A may protect the heart from some of the harmful effects of obesity. During the study, the group induced obesity in a vitamin A-deficient mouse model.
After 20 weeks, the researchers compared the mice’s heart and metabolism with obese mice that had adequate levels of vitamin A.
They found that obese, vitamin-deficient mice had repressed genes in their hearts associated with extracting energy from fat, extracting energy from glucose, and producing the energy-carrying molecule adenosine triphosphate.
All these areas are necessary for the functioning of metabolism.
This study demonstrated the role of vitamin A in maintaining the active expression of cardiac genes, which may reduce the subsequent development of dysfunction in diet-induced obesity.
Vitamin A (also known as retinoic acid) is an extremely important nutrient for vision, cell growth, cell division and reproduction, and immune support.
It also contains antioxidants that protect the body’s cells from the effects of free radicals (molecules produced when food is broken down in the body or when the body is exposed to tobacco smoke and radiation). Free radicals may play a role in heart disease and cancer.
Vitamin A can be obtained from many foods such as dairy products, liver, and leafy green vegetables such as spinach, carrots, pumpkin, and others.
