I'm not a vegan or vegetarian, but I go for plant based options occasionally and know vegetarians and vegans. With the current trends, it is pretty reasonable for plant based alternatives to reach price parity with meat products. Taste and texture wise, it's a mix bag, with some products ranging from great to mediocre.
It doesn't matter if it's plant or meat based, as long as you get the recommended intake of nutrients, your diet is going to be healthy. As for fast food doesn't matter if it's plant-based it's never going to be healthy. As for the image you posted, there really isn't anything wrong with the ingridients listed for plant-based. I'm not sure where you're getting that nonsense about it leading to higher rates of cancer too
thats cheap. what's your recipe?
