Expert explains that we have a lot to lose without a plant-based diet

Vegan plant based diet

Dr Michael Greger, an American physician who advocates whole foods and plant-based diet, spoke to a crowd of vegan enthusiasts about what is the science behind deciding to go vegan. Bellow, is what he said using CDC statistics and studies he has investigated during his career, about the correlation of animal produce consumption and chronic diseases.


Dr. Greger started showing statistics reports, release by the government about the correction of death and chronic diseases. Teasing the crowd by asking the question: what is the best way to prevent death?

That question was answered by using the latest CDC statistics on causes of death relating to chronic diseases, like heart disease, which topped number one in the CDC list for cause of deaths in the US. But, what Dr. Greger wanted was to get to the bottom as to what habits can be associated, with illnesses like chronic heart disease. Bellow are the two studies he discussed about.

Study 1

Dr Greger mentioned a study just released by the New England Journal of Medicine, which evaluated the relationship between changes in diet quality over time and the risk of death. In this research scientists calculated the total and cause-specific mortality among 47,994 women in the Nurses’ Health Study and 25,745 men in the Health Professionals Follow-up Study from 1998 through 2010. They observed over the period of 12 years, that improved diet quality was consistently associated with a decreased risk of death.

study 2

But, the only reason Dr. Greger spoke about the aforementioned research, is because prior to this finding, that improved diet quality equals to longevity, there was another study conducted in 2011. In this study, authors used competing risks survival analysis to evaluate associations of lifestyle and dietary factors with all-cause and cause-specific mortality among 50,112 participants in the Nurses’ Health Study. There were 4,893 deaths between 1986 and 2004: 1,026 from cardiovascular disease, 931 from smoking-related cancers, 1,430 from cancers not related to smoking, and 1,506 from all other causes.

After mentioning both studies, Dr Greger explained the interesting data that he found in the second study, concluding that without a plant- based diet we have a lot to lose.

Dr Greger explained that scientists in the study 2, quickly concluded that the high rate of death caused by heart disease was associated by a high dietary of cholesterol. But, he was amazed to find another piece of information in that study, which inherently leads to the conclusion that specific types of foods we consume, are the reason for an increased risk of death. He said:

“…But what is so neat about this study [study 2] is that it is a competing risks analysis. So, it allowed them to compare different risks to one another. So, consuming the amount of cholesterol found in just a single egg a day appears to cut a woman’s life short, as much as smoking 5 cigarettes a day for 15 years. The most protective behaviour, they found was fiber consumption: Even just a cup of oatmeals worth of fiber a day, appears to extend a woman’s life as much as four hours of jogging a week…” Then he added that it was worth noting that, “ the intake of cholesterol only found in animal foods was associated with living a shorter life, and the intake of fiber, only found in plants foods was associated with a longer life. The one specific food most tied to longevity was nuts.”

This is not the first time a plant- based diet has been in the spotlight, as recently it has been reported that a plant- based diet will provide all the nutrition you need and make you healthier. It seems that this message, is getting across at least in Britain, with reports that vegans are putting a quarter britons off meat.
