COVID-19: Which vaccines are effective against the delta variant?

The delta variant of SARS-CoV-2, which was first identified in India, is now the dominant form of the virus in the United Kingdom. In the United States, at least 10% of new cases are with this variant.

Blood clot warning: The way you sit at your desk could be increasing your risk

BLOOD clots are a potentially serious complication that needs to be treated quickly. The way you sit at your desk can increase your risk, warned Cheryl Lythgoe, Matron at Benenden Health.

How to live longer: The best time to eat to lower blood sugar and promote longevity

LIVE longer by making sure your blood sugars are well managed. For those with type 2 diabetes, and those without, how can you do that? After all, isn't it an internal process?

The development of type 2 diabetes might begin with the pancreas not being able to create sufficient or adequate supplies of insulin, but it is external processes that can help or hinder. Progressive research published in The Endocrine Society journal suggests that the time of day you eat can have an influence on blood sugar levels. "We found people who started eating earlier in the day had lower blood sugar levels and less insulin resistance," said lead researcher Dr Marriam Ali. Based at the Northwestern University in Chicago, Dr Ali said their results were independent of restrictive diets.

Vitamins and Supplements: Signs You're Low on Vitamin C

How Much Do You Need?

If you eat a balanced diet, it's pretty easy to get enough. Adult women (who aren't pregnant or breastfeeding) need 75 milligrams of vitamin C per day; men, 90 milligrams. A mere 1/2 cup of raw red bell pepper or 3/4 cup of orange juice will do it, while 1/2 cup cooked broccoli gets you at least halfway there. Your body doesn't make or store vitamin C, so you have to eat it every day.
