4 tablespoons of olive oil helps to boost the effects of good cholesterol

A Mediterranean diet really does help people at risk of heart disease, scientists have confirmed according to Daily mail.

In a new study, they found foods rich in olive oil help to enhance the benefits of so-called 'good cholesterol' - HDL.

Just four tablespoons of the widely used ingredient each day prevented plaque from forming in the arteries of those deemed at risk.

However, it didn't help to reduce levels of 'bad' cholesterol - LDL, a known risk factor of heart attacks and stroke.

How to boost your brain power at work WITHOUT coffee

With our hectic lifestyles, it's incredibly common to feel a dip in concentration at work according to Daily mail.

Unhealthy gut microbes a cause of hypertension, researchers find

Researchers have found that the microorganisms residing in the intestines (microbiota) play a role in the development of high blood pressure in rats according to Science daily.

Scientists studied two sets of rats, one group with high blood pressure ("hypertensive") and one with normal blood pressure ("normal"). The research team removed a portion of the biological material from the large intestine of each group. All animals were then given antibiotics for 10 days to reduce their natural microbiota. After the course of antibiotics, the researchers transplanted hypertensive microbiota to normal blood pressure rats and normal microbiota to the hypertensive group.

Antibiotics can Boost Bacterial Reproduction

The growth of bacteria can be stimulated by antibiotics, scientists have discovered.

The EPSRC-funded researchers exposed E.coli bacteria to eight rounds of antibiotic treatment over four days and found the bug -- which can cause severe stomach pain, diarrhea and kidney failure in humans -- had increased antibiotic resistance with each treatment according to Science daily.

This had been expected, but researchers were surprised to find mutated E.coli reproduced faster than before encountering the drugs and formed populations that were three times larger because of the mutations.

Eat hot peppers for a longer life? Study

 Like spicy food? If so, you might live longer, say researchers, who found that consumption of hot red chili peppers is associated with a 13 percent reduction in total mortality -- primarily in deaths due to heart disease or stroke -- in a large prospective study according to Science daily.

Going back for centuries, peppers and spices have been thought to be beneficial in the treatment of diseases, but only one other study -- conducted in China and published in 2015 -- has previously examined chili pepper consumption and its association with mortality. This new study corroborates the earlier study's findings.
