Besides helping lose weight, consuming a ketogenic diet — which is high fat, low protein and low carbohydrates — can also help maintain vision in patients with glaucoma, finds a study conducted over mice.

Glaucoma is a progressive disease in which damage to the cells that transmit visual information to the brain leads to vision loss and, in some cases, blindness.

The findings led by Denise Inman from the Northeast Ohio Medical University in the US showed that low carb, high fat diet protects retina cells and their connections to the brain from degeneration.

The results, published in the journal JNeurosci, found that feeding mice, genetically modified to develop glaucoma, a ketogenic diet composed of nearly 90 per cent fat for two months protected retinal cells from degeneration by increasing energy availability.

Although further research into this intervention is required, these findings suggest that a ketogenic diet may help to maintain vision in patients with glaucoma, the researchers said. (IANS)

Eat Right Amount of Good Fat to Stay Healthy

Different foods provide different types of fat. Some fats improve your health (omega-3s help your heart and brain) while some are detrimental to your health (trans fat increases heart disease risk factors)

How much one should eat to stay fit, healthy and disease-free? Consume between 20-35 percent of your calories from dietary fat, increase consumption of omega-3 fatty acids and limit the intake of saturated and trans fats, according to a research.

According to a latest paper from the US-based Academy of Nutrition and Dietetics, dietary fat for the healthy adult population should provide 20-35 percent of energy, with an increased consumption of n-3 polyunsaturated fatty acids and limited intake of saturated and trans fats.

“Nutritionists can help people understand that a total diet approach is more beneficial than simply reducing dietary fat and replacing it with carbohydrates, as a high intake of refined carbohydrate can also negatively affect health,” said the study published in the Journal of the Academy of Nutrition and Dietetics.

The paper recommended a food-based approach through a diet that includes regular consumption of fatty fish, nuts and seeds, lean meats and poultry, low-fat dairy products, vegetables, fruits, whole grains and legumes.

A simple and effective way to improve health is to eat more fish, nuts and seeds and to consume fewer desserts and convenience foods, it added.

“Fat is a critical nutrient, and certain types of fat, such as omega-3s and omega-6s, are needed for good health. For this and other health reasons, a fat-free diet is not recommended,” it noted.
