I’ve seen some documentaries that suggest by adopting a whole foods plant-based way of eating, many diseases can be either prevented or reversed. That looks very interesting.
Thank you for sharing a useful information.
One of my friends who has a skin problem tried a plant based diet for a month. He was surprised by the result. Not only his skin condition became better but also his mood also improved according to my friend. It is clear that processed meat is not good for us. However, if you could add some information about fish, that would be better since I prefer fish to meat.
Thank you for reading. The data on fish consumption and human health is largely reassuring and seems to be associated with a lower risk of cardiovascular disease. Still, people who do not eat seafood are perfectly fine and there is no recommendation to start eating seafood. There is definitely plenty of research about red and processed meats and the association with diabetes as well as cardiovascular disease and increased risk of death.
Do you know please of even one study where eating meat less than 6 times a week adversely affects health? Meta-analysis data Ive come across indicates eating meat 7-10 times a week may lead to health issues for some people. Thanks
Hi Steve, Thanks for reading. There is a list of resources at the bottom of the post, and these include multiple research studies and papers supporting a plant-based diet with limited red and processed meats as best for overall health.
This article doesn’t say a word about fish. How does fish fit in?
Fish are animals.
The data on fish, eggs, dairy, and chicken is mixed, and at this point I’d say if you enjoy these foods, try to obtain them from reputable sources, like local farms. The healthier the animals are and the less hormones or antibiotics they received, the better for you.
Well explained, clear and very simple to adopt. Many thanks
I wonder whether this article is really an information or if it is sort of propaganda for vegetables.
Indeed, the article mentions that red meat and processed are detrimental. Ans without mentioning wite meat and fish (and eggs), it concludes that we have to eat plant based nutrition.
Why not mentioning the halth interest of other animal proteins ?
Why directly go to the common vegan conclusion : less animal proteins is better ?
Thanks for reading, Luc! There is a list of resources at the bottom of the post, and these include multiple research studies and papers supporting a plant-based diet for overall health. One does NOT have to be vegan to be plant-based. Just eating mostly fruits, vegetables, beans and lentils, nuts and seeds, and whole grains, all in the most unprocessed forms possible, is well-established as the healthiest approach. The data on fish, eggs, dairy, and chicken is mixed, and at this point I’d say if you enjoy these foods, try to obtain them from reputable sources, like local farms. The healthier the animals are and the less hormones or antibiotics they received, the better for you.
