What you need to know about new research.A new study in the journal PLOS Genetics revealed that people with Type A blood are more likely to have a severe case of Covid-19.
People infected with COVID-19 — even in mild cases — arein the three to six months after their illness, a large study found.
The risk was much higher in people who had severe cases of COVID-19, the researchers, from Sweden, found. In people who were seriously ill, their chance of developing a blood clot was 290 times higher than normal. That risk went up in people with mild cases as well, at 7 times higher.
For the study,, researchers tracked more than 1 million people who tested positive for COVID-19 between Feb. 2020 and May 2021, and compared them to 4 million people of the same demographics who hadn't gotten the virus.

The researchers said that the risk of clots was higher in people who had the earlier versions of COVID-19 in the first few waves, which they ascribed to medical staff gaining a better understanding of how to treat the virus and more people getting vaccinated.
"For unvaccinated individuals, that's a really good reason to get a vaccine — the risk is so much higher than the risk from vaccines," Anne-Marie Fors Connolly, principal study investigator from Umea University in Sweden,.
The #1 Best Drink for Preventing Bone Loss
We consulted medical expert Amy Goodson, MS, RD, CSSD, LD, on the number one drink to sip on for preventing bone loss.Human bones are constantly undergoing a regenerative process, by reabsorbing old bone and creating new. As a result, at any given moment our skeletal makeup is a healthy mix of old and new bones—about every 10 years, our entire skeleton is replaced. Bone loss occurs, however, when that mix becomes imbalanced. When more old bone is reabsorbed than new bone is created, our bodies become more at risk for fractures and breaks even when doing seemingly simple tasks.

And another recent study has backed up Connolly's statement that getting vaccinated not only lowers the risk of getting COVID-19 and, but is also far less likely to cause a blood clot.
That vaccines can cause blood clots became a talking point among anti-vaccine protestors, but the risk is extremely low. Ain March found that the risk of developing a blood clot is 28 to 32 times higher in people who contracted COVID-19 than those who had been vaccinated with Pfizer or Moderna's formulations.
More than 550 million doses of Pfizer and Moderna's vaccines that have been administered in the U.S. so far, and the Centers for Disease Control say that there has been no evidence that either causes blood clots.

The post What You Need To Know About Adult-Onset Allergies appeared first on Reader's Digest Canada.In 2019, for the very first systematic study of allergies in adulthood, the Center for Food Allergy & Asthma Research (CFAAR) surveyed approximately 40,000 people across the United States and found that one in 10 were food-allergic. Half of those people, the survey revealed, developed at least one of their allergies after the age of 18. “We were very surprised by the results,” says Ruchi Gupta, CFAAR’s director.
