There's also an issue of taste. I dislike the taste of many foods considered healthy for me. I try to eat the ones I enjoy but many are expensive depending on the season.

For example, I cannot stomach green beans. Attempting to chew them results in vomiting within my mouth. The smell of them alone is repulsive to me.

If I can have a bland solution to eating healthy - that's a win for me. The only thing preventing me from trying Soylent is the price of buying enough for 2 people, since all of my current meals are shared. Having to buy normal groceries and Soylent would nearly double my monthly cost for foodstuffs.

I'd have a healthier, cheaper diet if I only had to buy food for myself.

E:

Not to mention every "cheap alternative healthy food" to Soylent I see mentioned only targets a small section of nutrients and vitamins and often ignores proteins altogether. They aren't well rounded - even if they're healthier/cheaper than McDonalds. Soylent strikes the "well rounded" healthy food. Without the hassle of having to buy groceries or prepare the food.
