The biggest food and beverage companies in the world consist of Nestle, Coca Cola, Pepsi, Unilever, Mondelez, Kraft Heinz, Tyson, and Hormel. These are the main ones but there are other ones as well. I have linked the rest in my other idea below. While it does not cover every single company in the group, it highlights the Main Titans of the sector.
I have shown their main products showing why they are the Titans dominating grocery stores. Especially thing like Pepsi and Coca Cola. Just for example, people do not know that they own many other brands and companies themselves.
