Eggs are good for the heart

Eggs are not bad for heart health, say experts. US egg expert Dr Don McNamara insists that their bad reputation is no longer warranted and even Heart Foundation has lifted its recommended intake to six eggs a week.

“Seniors have been afraid to eat eggs because for 40 years they have been worried about the dietary cholesterol,” said  nutritional biochemist McNamara.

“But, over the years, the research has clearly shown that cholesterol in our food doesn’t impact our risk for heart disease — that is saturated fat and trans fat,” he added.

Eggs are low in saturated fat and consist of some of the vital compounds like choline that are considered good for metabolism and for foetal brain development during pregnancy.

It also contains lutein, which is known to lower the risk for cataracts and macular degeneration.

McNamara said those who eat eggs for breakfast feel fuller for longer and reduce the risk of overeating at lunch.

“Eggs have the highest quality protein you can buy in the supermarket for the lowest cost, and they contain every vitamin and mineral we need except for vitamin C,” he said.

Stem cells become vision cells

Scientists at the University of Florida have announced that they have successfully programmed bone marrow stem cells to repair damaged retinas in mice, moving a step closer to developing a potential treatment for one of the most common causes of vision loss in older people.

The researchers say that the success in repairing a damaged layer of retinal cells in mice indicates that blood stem cells taken from bone marrow can be programmed to restore a variety of cells and tissues, including ones involved in cardiovascular disorders like atherosclerosis and coronary artery disease.

“Ultimately you would not give the drugs to the patient, you would give the drugs to their cells. Take the cells out, activate certain chemical pathways, and put the cells back into the patient,” said Dr Maria B Grant, UF’s College of Medicine.

Safe and effective antiretroviral drug

Emory University researchers have found that a member of a new class of antiretroviral drugs is safe and effective for patients beginning treatment against HIV.

They came to this conclusion after analysing the results of a two-year multisite phase III clinical trial, and comparing this drug with standard antiretroviral drugs.

“These results provide an additional potent, well tolerated treatment option for newly diagnosed patients with HIV infection,” says lead author Dr Jeffrey Lennox.

The scientists found that an HIV integrase inhibitor called Raltegravir is overall as effective as widely used efavirenz, a reverse transcriptase inhibitor.

The researchers also observed that Raltegravir had faster onset of action and fewer adverse side effects.

Black tea can help fight diabetes

Besides boosting the immune system, black tea can be used to control diabetes, according to a new study.

The research has been published in the ‘Journal of Food Science’, published by the Institute of Food Technologists.

To reach the conclusion, researchers from the Tianjin Key Laboratory in China studied the polysaccharide levels of green, oolong and black teas and whether they could be used to treat diabetes.

Polysaccharides, a type of carbohydrate that includes starch and cellulose, may benefit people with diabetes because they help retard absorption of glucose. The researchers found that of the three teas, the polysaccharides in black tea had the most glucose-inhibiting properties.
