Maybe stop eating shampoo then. (= They partly own L’Oréal, and by extension all the L’Oréal brands: Garnier, Maybelline, Vichy, Biotherm, etc.)
To your actual point though: A) that depends on which country you live in, given that their products are manufactured differently in each country/region. B) it does also depend on what brand you’re referring to. I find it highly unlikely you dislike EVERYTHING in the Nestle machine. Hot Pockets? Perrier water? Nerds? Smarties??
