New research, published in the journal Circulation, finds that including walnuts in the diet reduces the total cholesterol and lowers levels of LDL cholesterol, which is usually referred to as “bad” cholesterol.
For the study, the researchers recruited 636 participants aged between 63 and 79 years. They all resided in Barcelona, Spain, or Loma Linda, U.S. All the participants were healthy and had no significant health conditions.
The scientists divided the participants into two groups and prescribed to one group to eat half a cup of raw walnuts every day, while the other group was instructed to exclude walnuts from the diet.
At the end of the study, the researchers noticed that those who consumed walnuts reduced their LDL cholesterol levels by an average of 4.3 milligrams per deciliter (mg/dl) and their total cholesterol by an average of 8.5 mg/dl.
Researchers from Duke University School of Medicine in Durham, U.S., have investigated the link between high cholesterol and cancer cell growth and spread. According to the study, high cholesterol levels fuel cancer cells by increasing resistance to a form of cell death.
For their study, the researchers used cell lines and mice models. The scientists noticed that exposure to 27HC, which is a derivative of cholesterol obtained through oxidation and implicated in cancers, resulted in the growth of tumors that were highly metastatic.
Lead researcher Dr. Donald McDonnell, Ph.D., says: “There is an abundance of epidemiological evidence linking hypercholesterolemia to poorer outcomes in [people] with most cancers, [and now] we think we have found why and have defined a completely new way to treat these cancers.”
A new study, conducted by researchers from the University of Reading in the United Kingdom, finds that people drinking dairy milk have lower levels of both types of cholesterol and a lower risk of coronary heart disease compared to people who do not drink milk.
For their study, a team of researchers completed a meta-analysis of three surveys that included more than 400,000 persons.
Lead researchers Vimal Karani, a professor of nutrigenetics and nutrigenomics at the University of Reading: “We found that among participants with a genetic variation that we associated with higher milk intake, they had higher BMI [and] body fat, but importantly had lower levels of good and bad cholesterol. We also found that those with the genetic variation had a significantly lower risk of coronary heart disease. All of this suggests that reducing the intake of milk might not be necessary for preventing cardiovascular diseases.”
A team of researchers from the Medical University of Vienna is in the process of testing the safety of their experimental cholesterol-lowering vaccine in 72 volunteers. This vaccine, successfully tested in mice, can help prevent heart disease in the future.
The treatment was designed to stop deposits of fat from clogging the arteries. It can be an alternative way to lower the risk of stroke, angina, and heart attacks.
Dr. Guenther Staffler and his colleagues from The Netherlands Organisation of Applied Scientific Research explain that it will take years more of testing to know if the treatment will be safe and effective enough to use. The scientists also add that this medication is not an excuse for people to avoid exercise and eat high-fat food.
A team of researchers from Pennsylvania State University and Kailuan Hospital in China finds that moderate drinking may slow the decline of ‘good’ high-density lipoprotein (HDL) cholesterol.
For their study, the scientists analyzed the data of 80,081 Chinese men and women whose average age was 49 years. The participants were divided into five groups: never, past, light, moderate, and heavy drinkers. Moderate drinking was defined as 0.5-1 drink a day for women and 1-2 drinks a day for men.
The researchers found that moderate drinkers had a slower decline in HDL than never-drinkers and heavy-drinkers. They also found that HDL levels fell more slowly in people drinking beer.
