BYLINE: By KEVIN SMITHAPENSTEINAUSTIN, Texas (AP) An old study finding that a vegetarian diet increases the risk of cardiovascular disease and obesity is back in the news.

But it’s not surprising that it’s coming up now, because a lot of Americans are eating meat.

A new study published in the journal Obesity finds that vegetarians who ate meat at least 20 percent of their meals for a year had significantly lower risk of dying from cardiovascular disease than those who ate less than 20 percent.

That’s a reversal of previous research showing that a vegan diet is associated with fewer cardiovascular risks than a meat-eating diet.

The new study also found that vegetative people also had lower rates of all-cause mortality compared with meat-eaters.

It’s not clear how vegetarian people fare when it comes to cardiovascular disease.

It could be that the vegetarian diet was associated with less cardiovascular risk.

Or it could be there was a benefit to eating a vegetarian or vegan diet for heart health, says lead author Jennifer J. Flegal, an associate professor of nutrition at the University of Texas Health Science Center at Houston.

It was a study that was not designed to look at a single nutrient or diet, she says.

It was a random sample, and we could not know for sure whether vegetarians were healthier or healthier than meat eaters.

It may be that vegetatives are healthier because they are eating a plant-based diet, which is rich in plant proteins and vitamins, and it may be a protective factor against heart disease, says Flegal.

And there are other potential explanations.

The American Heart Association, the American Dietetic Association and the American Diabetes Association have all endorsed a vegan or vegetarian diet, and there is a growing number of researchers in the field trying to understand the health benefits of a plant based diet.

One of those studies was published last year in the Journal of the American College of Nutrition.

It found that a plant free diet is linked to lower risk factors for cardiovascular disease, such as hypertension and high blood pressure, among other things.

The study didn’t examine the link between vegetarianism and heart disease specifically.

But a lot has changed in the past decade, especially in the medical community, says Michael Rimm, a professor of epidemiology at the Icahn School of Medicine at Mount Sinai.

It’s important that we understand what’s happening, he says.

The evidence is mounting, and people are looking for answers, particularly in terms of the health implications of this.

A lot of the public health recommendations in the United States, for example, are based on a vegetarian approach.

They are not based on the idea that vegetarian diets are healthier than omnivores.

So, there is an important public health agenda for people to address this.

We need to take action on a plant, plant based approach to heart disease.

That may be part of why the vegan diet has been gaining popularity.

It could be, Flegal says, that vegans are eating more plant proteins, because they can eat them in a plant.

It may be because they have fewer saturated fat and cholesterol.

And it may also be because there are fewer processed foods, and a lot more fruits and vegetables, she adds.

The best way to eat is with fresh, whole foods, not with processed foods and added sugars, she explains.

It depends on your specific health needs, says co-author Mark S. Cohen, an epidemiologist at the Harvard School of Public Health in Boston.

And, he adds, you also need to remember that the effects of one type of diet on the body may vary based on what type of food you eat.

But even if one type is good for you, if it doesn’t match up to what you eat in the other, that’s still a risk factor, Cohen says.

It can also depend on the timing.

In some people, it may increase their risk of heart disease in the short term.

And in other people, the longer term, it might increase their health risks.

But you don’t need to be overweight to benefit from a plant eating diet, he explains.

And even if you are, a vegetarian can have the healthiest diet.

Vegetarian diets may not be ideal for everyone.

But you can still enjoy a lot with a plant or a plantless diet, Cohen adds.

Flegal says more research is needed to understand how a vegetarian lifestyle affects heart health.

It is a fascinating topic that deserves more study, says Rimm.

And hopefully, more people will be able to learn more about it, he added.

There are a lot fewer studies out there looking at plant based diets.

But we do know that people who have been eating a vegan, or plant-free diet, have reduced risk of developing cardiovascular disease compared to those who have not, Cohen and Flegal say.

And they are also less likely to have type 2 diabetes, the leading cause of death in the U.S.
