Capitalism kills

This implies that people are missing meals because of some sort of shortfall. This isn't a matter of "oh I don't feel like breakfast today" = "I'm literally starving", but instead a condemning realisation that capitalism simply cannot provide enough food for people.

Nor can any other ideology. Capitalism at least succeeds in providing more food every single year.

The critical issue is that people do not have enough capital to buy that food.

Good point. Again, is the case in other places too. I believe you would have a more compelling argument if you attack the contradictory absurdities of capitalism rather than capitalism as a whole being a failed system.

And how is the average Indian meant to afford that? Again, capital leads to food withering away on a shelf.

The average Indian can afford bananas at those prices. The point was that compared to US capital those prices are relatively even cheaper for the average American.

Again, capitalism incentivises the purchase of unhealthy options. How are you meant to eat healthy when corporate propaganda is shoved down your throat at every turn?

A more compelling argument would be that processed food is engineered to be addictive in ways that normal crops or wheat or rice is not.

Ultra-processed foods are industrially formulated with added sugar, artificial sweeteners, additives and flavorings to be highly rewarding and even addictive. They can alter the brain's reward pathways the same way that other addictive substances do, making them challenging to consume in moderation.

It most certainly is. I ensure you that you'll eventually realise that.

There isn't enough land on that planet for communism to work with 8.2 billion humans living on the same planet.
