Do vegetarians live longer?

In this brief guide, we will answer the query, “Do vegetarians live longer?” and will discuss the reasons why vegetarians live longer than non-vegetarians.

Do vegetarians live longer?

Yes, vegetarians live longer. 83 years against 73 years: that’s the average life expectancy difference between vegetarian and non-vegetarian males studied by Loma Linda University’s team of researchers in the US. For women, being vegetarian extended their lives by 6 years, allowing them to live to an average age of 85.

Over 14 years, researchers at Loma Linda University studied the diets, lifestyles, and illnesses of 34,000 Seventh-day Adventists in the United States. This Christian sect promotes a vegetarian diet as well as abstinence from drugs and alcohol. Because most Adventists don’t smoke or drink, they are excellent subjects for big population studies. Now they can see how their other lifestyle decisions, especially nutritional ones, affect their health and lifespan.

According to the results of the research, five practices may significantly increase your lifespan. They’d described themselves as the following:

·         Plant-based diet

·         Frequent consumption of nuts (about five times a week)

·         Physical activity

·         Abstinence from tobacco use

·         Maintaining a healthy weight

A decade more of life might be yours if you follow these lifestyle recommendations, according to the findings. They individually add up to an average of 2–3 more years, and the best part is that they add up.

This is supported by newer research from Harvard’s T.H. Chan School of Public Health. Healthy habits including eating well, exercising, avoiding smoking, and drinking moderately or not at all may add ten years or more to your life expectancy. All five factors were shown to increase life expectancy, but experts feel that eating a healthy, plant-based diet, in particular one rich in whole foods, is the most essential.

The nutritional value of a plant-based diet extends well beyond the essential vitamins and minerals it contains. Fiber, resistant starch, and powerful plant components including antioxidants and phytochemicals are all found in high concentrations in fruits and vegetables. Plant-based diets include less saturated fats and cholesterol; thus they have advantages over animal-based diets as well.

And turning green is supported by a variety of other factors as well. Some of the world’s earliest societies have documented links between plant-based diets and long life. The traditional Mediterranean diet is known for its abundance of vegetables, whereas traditional Okinawan Japanese cuisine emphasizes entire foods.

Reasons: why vegetarians live longer?

Low blood pressure

According to a recent study, vegetarians not only have on average lower blood pressure but vegetarian diets might also be utilized to treat high blood pressure.

Lower risk of death

In a study of over 70,000 participants conducted in 2013, vegetarians had a 12% lower mortality rate than non-vegetarians. Vegetarians may have a decreased overall risk of chronic illness because they consume less saturated fat and cholesterol, which block arteries.

Better moods

Researchers in 2012 found that eating a high-fat, high-fish, or vegetarian diet was associated with better emotions among research participants. The vegetarian diet improved people’s mood more than the other two diets after two weeks, according to the study’s findings.

Less risk of heart disease

Vegetarians had a 32% lower risk of developing ischemic heart disease, according to a 2013 study involving 44,000 adults.

Lower cancer risk

Researchers at Loma Linda University in California examined the relationship between various vegetarian diets and cancer risk in adults with low overall cancer risk and found that a vegetarian diet may have protective effects. Vegans had the lowest cancer risk, particularly for malignancies most frequent in women, such as breast cancer, even if the data isn’t conclusive.

A study led by Dr. Ornish and his colleagues found that after only two weeks on a plant-based diet, men who had been vegan for a year had an eight-fold increase in cancer-fighting capacity in their bloodstreams. The before and after photos can be seen right here. This study will warm your heart if you or someone you know has ever suffered a cancer scare. It’s because there’s actual hope — something you can do to avoid contracting “the big C.” 

Lower risk of diabetes

Vegetarians have been proven to have a decreased chance of acquiring diabetes, according to research. It will not cure the condition, but by helping you maintain your weight and improve your blood sugar management, the diet may minimize your risk.

A decreased risk of obesity

 Studies suggest that vegetarians are thinner and have lower cholesterol and body mass index than meat-eating people (BMI). Vegetarian diets may help people lose weight and keep it off in the long run, according to some research.
