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.

Learn How Muscles Help Burn Fat During Exercise

Burning fat is likely to impact multiple aspects of metabolic health related to diabetes, heart disease and other conditions

Ever thought what helps burn fat across your body while exercising? According to a study, it is a molecule in our muscles that is produced during exercise and contributes to the beneficial effects of exercise on metabolism.

“Our finding bolsters the underlying notion that signals generated in exercising muscle are released into the circulation and influence other tissues such as fat cells and liver,” said senior author Robert Gerszten at Massachusetts General Hospital, the primary teaching hospital of Harvard Medical School.

The researchers knew that a protein called PGC-1? regulates metabolic genes in muscle and contributes to the response of muscle to exercise.

But how this protein conveys signals to other tissues was unclear so far.

Gerszten and his colleagues forced the expression of PGC-1? in muscle cells and then looked for metabolites that were secreted from the cells.

They identified ?-aminoisobutyric acid (BAIBA) as one such metabolite and found that it increased fat cells’ expression of genes that are involved with burning calories.

BAIBA also decreased weight gain and helped balance blood sugar levels in mice, said the study published in the journal Cell Metabolism.

Further research revealed that BAIBA levels rise during exercise and are inversely associated with metabolic risk factors.

“The findings suggest that BAIBA may contribute to exercise-induced protection from metabolic diseases. Manipulating BAIBA – or enzymes that generate BAIBA – may have therapeutic potential,” said Gerszten.

Burning fat is likely to impact multiple aspects of metabolic health related to diabetes, heart disease and other conditions, the study concluded.  (IANS)
