NEW YORK (Reuters Health) - Vegetarians are one-third less likely to be hospitalized or die from heart disease than meat and fish eaters, according to a new UK study.

Earlier research has also suggested that non-meat eaters have fewer heart problems, researchers said, but it wasn't clear if other lifestyle differences, including exercise and smoking habits, might also play into that.

Now, "we're able to be slightly more certain that it is something that's in the vegetarian diet that's causing vegetarians to have a lower risk of heart disease," said Francesca Crowe, who led the new study at the University of Oxford.

Still, she noted, the researchers couldn't prove there were no unmeasured lifestyle differences between vegetarians and meat eaters that could help explain the disparity in heart risks.

Crowe and her colleagues tracked almost 45,000 people living in England and Scotland who initially reported on their diet, lifestyle and general health in the 1990s.

At the start of the study, about one-third of the participants said they ate a vegetarian diet, without meat or fish.

Over the next 11 to 12 years, 1,066 of all study subjects were hospitalized for heart disease, including heart attacks, and 169 died of those causes.

After taking into account participants' ages, exercise habits and other health measures, the research team found vegetarians were 32 percent less likely to develop heart disease than carnivores. When weight was factored into the equation, the effect dropped slightly to 28 percent.

The lower heart risk was likely due to lower cholesterol and blood pressure among vegetarians in the study, the researchers reported this week in the American Journal of Clinical Nutrition.

Meat eaters had an average total cholesterol of 222 mg/dL and a systolic blood pressure - the top number in a blood pressure reading - of 134 mm Hg, compared to 203 mg/dL total cholesterol and 131 mm Hg systolic blood pressure among vegetarians.

Diastolic blood pressure - the bottom number - was similar between the two groups.

Crowe said the difference in cholesterol levels between meat eaters and vegetarians was equivalent to about half the benefit someone would see by taking a statin.

The effect is probably at least partly due to the lack of red meat - especially meat high in saturated fat - in vegetarians' diets, she added. The extra fruits and vegetables and higher fiber in a non-meat diet could also play a role.

"If people want to reduce their risk of heart disease by changing their diet, one way of doing that is to follow a vegetarian diet," Crowe told Reuters Health.

However, she added, you also don't have to cut out meat altogether - just scaling back on saturated fat can make a difference, for example. Butter, ice cream, cheeses and meats all typically contain saturated fat.

A veg diet does work if you stay on it. My Dad has heart trouble went through the open heart operation, had stints put in, took all kinds of vitamins[still does].Was told go home there is nothing we can do for you. if he walked 15-20 feet he had to sit down for 6 to 10 min. He started the all veg diet a year and 1 month ago, now goes up and down stairs, walks 3 blocks everyday is alret and can still drive he is 93. The diet is what did it, he ate what they [heart doctor] told him, no milk, cheese, meat, oil, butter[no bad oil and fat]. It has done wonders. You are never too old to start. The heart book diet said you would notice a change within 6 months and that was true.

I suppose our government will decide this is best for everyone and create policies that require us all to go meat free at least 3 days a week. I’d like to see data related to family history tied into this survey. Some people’s genetic makeup is not affected by eating meat 7 days a week and other are.
