Vegetable diet, or vegetarianism, might be both good and bad for the health. Scientists have discovered some new pros and cons of being a vegetarian. Today, let us study how plant-based diet affects the heart.
When vegetable diet is good: It reduces the risk of heart disease
According to a new study, plant nutrition is better for the heart. The study was published in the journal of the American Heart Association. It shows that a diet based on vegetables, legumes, nuts and whole grains reduces the risk of heart disease in middle-aged people.
Previously, scientists have already come to the conclusion that vegetable diet reduces the likelihood of getting heart failure by 40%. Now, they have confirmed that it also reduces the risk of death from heart disease exactly by the same percentage.
The study: Details
The lead author of the new study was Casey M. Rebholz, PhD, Assistant Professor at Johns Hopkins Bloomberg School of Public Health. His work analyses data from 12,168 middle-aged people. They participated in a study of the risk of developing atherosclerosis from 1987 to 2016.
So, the results showed that the likelihood of encountering a cardiovascular disease (myocardial infarction or heart failure) is 16% less in people who prefer vegetable diet. Also, among those who had the most plant-based foods in their nutrition, mortality was reduced by 25%, and cardiovascular mortality by 32%
When plant-based diet is bad: It increases the risk of stroke
At the same time, another recent study have proved that vegetarians are more at risk to have a stroke. With plant-based nutrition, it increases by 20%.
Oxford scientists have conducted a large-scale study among vegetarians, meat-eaters, and those who eat vegetables and fish. They wanted to study the health effects of various types of nutrition. Finally, the results have confirmed that people who abandoned meat are less likely to have a cardiovascular disease. Nevertheless, the risk of strokes in them is higher than in meat-eaters.
Details of the study: vegetable diet and strokes
Scientists conducted a study among 48 thousand people, collecting data on their diet, health, lifestyle and other parameters. Among them, 24,400 were meat-eaters, 7,500 ate fish, and the rest were vegetarians and vegans. In total, the analysis took eighteen years.
The study showed that vegetarians have a 20% greater risk of stroke compared with meat-eaters.
