Consuming walnuts daily can reduce the number of LDL particles, a predictor of cardiovascular disease risk.
Washington [US], August 31 (ANI): According to a new research, healthy older adults who ate a handful of walnuts (about 1/2 cup) a day for two years modestly lowered their level of low-density lipoprotein or LDL cholesterol levels.
Consuming walnuts daily also reduced the number of LDL particles, a predictor of cardiovascular disease risk.Studies have found for example that people tend to underestimate how much they drink.LinkedIn SAO PAULO: Brazil, the world's largest beef exporter, has suspended beef exports to its No 1 customer China after confirming two cases of"atypical" mad cow disease in two separate domestic meat plants, the agriculture ministry said on Saturday..
The findings of the study were published in the American Heart Association's flagship journal 'Circulation'.Walnuts are a rich source of omega-3 fatty acids (alpha-linolenic acid), which have been shown to have a beneficial effect on cardiovascular health.The new study, however, was designed to get around those limitations."Prior studies have shown that nuts in general, and walnuts in particular, are associated with lower rates of heart disease and stroke.The suspension is a major blow for Brazilian farmers: China and Hong Kong buy more than half of Brazil's beef exports.One of the reasons is that they lower LDL-cholesterol levels, and now we have another reason: they improve the quality of LDL particles," said study co-author Emilio Ros, MD, PhD, director of the Lipid Clinic at the Endocrinology and Nutrition Service of the Hospital Clinic of Barcelona in Spain.Marcus and his colleagues recruited 100 people with a history of paroxysmal atrial fibrillation, most of them men, and had them wear electrocardiogram monitors that tracked their cardiac rhythms around the clock."LDL particles come in various sizes.
Research has shown that small, dense LDL particles are more often associated with atherosclerosis, the plaque or fatty deposits that build up in the arteries," Ros explained.The researchers used other, objective measures to track alcohol intake as well.It said"atypical" mad cow disease develops spontaneously and is not related to eating contaminated foods."Our study goes beyond LDL cholesterol levels to get a complete picture of all of the lipoproteins and the impact of eating walnuts daily on their potential to improve cardiovascular risk," Ros added.In a sub-study of the Walnuts and Healthy Aging study, a large, two-year randomised controlled trial examining whether walnuts contribute to healthy ageing, researchers evaluated if regular walnut consumption, regardless of a person's diet or where they live, has beneficial effects on lipoproteins.And they did routine finger-stick blood tests to measure participants’ levels of phosphatidylethanol, or PEth, a biomarker that gives some indication of a person’s recent alcohol consumption.This study was conducted from May 2012 to May 2016 and involved 708 participants between the ages of 63 and 79 (68 per cent women) who were healthy, independent-living adults residing in Barcelona, Spain, and Loma Linda, California.The OIE had subsequently been informed of the two cases, in compliance with international norms, the ministry said.Story continues Participants were randomly divided into two groups: active intervention and control.The data indicated that alcohol was often a trigger for arrhythmias.
Those allocated to the intervention group added about a half cup of walnuts to their usual daily diet, while participants in the control group abstained from eating any walnuts.After two years, participants' cholesterol levels were tested, and the concentration and size of lipoproteins were analysed by nuclear magnetic resonance spectroscopy.The higher a person’s blood alcohol concentration, the greater their likelihood of having an arrhythmia.The country's powerful agribusiness sector is one of the main drivers of its long-lagging economy.This advanced test enables physicians to more accurately identify lipoprotein features known to relate to the risk of cardiovascular disease.The two-year study had a 90 per cent retention rate (632 participants completed the study).She said that health care providers should have conversations with their patients, especially those who have atrial fibrillation, about how much alcohol they consume and whether it would be prudent for them to cut back or avoid it.Complete lipoprotein analyses were available in 628.
Among key findings of all study participants: 1.“Drinking is something that we can both monitor and modify on an individual basis.At 2 years, participants in the walnut group had lower LDL cholesterol levels -- by an average of 4.3 mg/dL, and total cholesterol was lowered by an average of 8.” Dr Piano said that she would like to see more research on diverse groups of people.5 mg/dL.2.“We certainly need a larger sample size of women,” she said.
Daily consumption of walnuts reduced the number of total LDL particles by 4.3 per cent and small LDL particles by 6.According to the Centers for Disease Control and Prevention , an estimated 12.1 per cent.These changes in LDL particle concentration and composition are associated with a lower risk of cardiovascular disease.Dr.3.
Intermediate Density Lipoprotein (IDL) cholesterol also decreased.” For women, it means having no more than three drinks on any single day and a maximum of seven drinks in a week.It is known that IDL cholesterol is a precursor to LDL and refers to a density between that of low-density and very-low-density lipoproteins.In the last decade, IDL cholesterol has emerged as a relevant lipid cardiovascular risk factor independent of LDL cholesterol.The federal government defines a standard drink as 12 ounces of regular beer, five ounces of wine, or one and a half ounces of distilled spirits (40 per cent alcohol).4.LDL cholesterol changes among the walnut group differed by sex; in men, LDL cholesterol fell by 7.“This shows that these atrial fibrillation events are not simply due to random chance, and that there are modifiable factors that can be harnessed to reduce the chances that an event will occur,” he said.
9 per cent and in women by 2.6 per cent.But for those without a history of atrial fibrillation, he said, the findings should serve as a caution against excessive drinking, because it appears that alcohol can interfere with the heart’s electrical properties."While this is not a tremendous decrease in LDL cholesterol, it's important to note that at the start of the study all our participants were quite healthy, free of major non-communicable diseases," Ros said."However, as expected in an elderly population, close to 50 per cent of participants were being treated for both high blood pressure and hypercholesterolemia.By Anahad O'Connor © The New York Times This article originally appeared in.Thanks in part to statin treatment in 32 per cent, the average cholesterol levels of all the people in our study were normal," Ros explained.
"For individuals with high blood cholesterol levels, the LDL cholesterol reduction after a nut-enriched diet may be much greater.Eating a handful of walnuts every day is a simple way to promote cardiovascular health," Ros added."Many people are worried about unwanted weight gain when they include nuts in their diet.Our study found that the healthy fats in walnuts did not cause participants to gain weight," Ros continued.The major limitation of this investigation is that both participants and researchers knew who was and was not eating walnuts.
However, the study did involve two very different populations with distinct diets."The outcomes were similar in both groups, so we can safely apply the results of this study to other populations," Ros said.More research is also needed to clarify the different LDL results in men and women.According to the American Heart Association, walnuts are especially high in omega-3 fatty acids, the same heart-healthy fat found in oily fish.A serving size is a small handful or 1.
5 ounces of whole nuts or 2 tablespoons of nut butter.The study was funded by the California Walnut Commission.(ANI) TRENDING.
