Grits are ground dried maize - a grain, not exactly the most nutritious thing in the world but it does taste good, I love it for breakfast myself, I used to eat oats every morning thinking I was eating healthy. It wrecked havoc with my teeth, needed lots of fillings. Get organic, most maize nowadays is GMO, avoid store bought processed ones if you can. General rule is to avoid refined, processed, & manufactured food as much as you can. Get nixtamalized corn and add lots of butter to it, I add milk and a bit sugar - I have a terrible sweet tooth. I have been doing sugar free February this month though. Important thing is don't make it a staple, switch up your breakfast routine.
