I quit for my health first and foremost, followed by an urge to assist the environmental - I'm asthmatic and since quitting meat, my asthma is virtually non-existent despite being a keen runner and HIIT fan.
I also have a very strong history of colorectal and stomach cancer in my family so would like to mitigate the risk as best I can.
That being said, I am not vegan, because veganism is much more than what people eat, and extends to far more areas in a persons life.
I eat a plant based diet, so eat loads of vegetables, salads, oatmeal with fruit, whole meal or lentil pasta with pesto, baked tofu bits etc. I don't now, nor will I ever eat a lentil curry and I fucking hate chickpeas 😁 But I do closely track my macros so I get enough protein and carbs for my strength training, and I only very rarely eat an impossible burger.
For me, there is no incentive to eat the fake meat on a regular basis as my focus is gut health, which vegan cheese doesn't really contribute to.
But I totally understand why folk would want vegan meats, just because a person becomes a vegan, it doesn't mean they forget how much they love the taste of meat 🙄 I don't miss meat at the moment, but me not eating meat for 6 months and then eating my mum's roast lamb on Easter Sunday is better than me eating meat 6 days a week like I was when I was on a keto diet...
I think anything that can help bring awareness to animal welfare and sustainable farming globally is a good thing, but ultimately we as humans, have so many varied approaches to what can keep us healthy. One size does not fit all.
