There’s an inverse relationship when it comes to income and veganism. Lower income people are more likely to be vegan than high income. Additionally, POC are significantly more likely to be vegan. The image that veganism is for rich white people is a myth.
For me, meal replacements such as Soylent (used to be Ensure before I became vegan) are a big part of my diet. I’ve always had an easier time with liquids than solids.
