I think people have different ideas about what is healthy food. Like tofu, many consider it healthy because it's plant based, but soy it's actually bad for your thyroid. Anyway, here's what SimsWiki says about this lifestyle. To get and maintain this lifestyle, your sims don't need to eat only healthy food, but they need to eat it often enough, say at least once a day, and they also need to avoid what is considered as junkfood. Everything else is neutral food and won't sway your sim's lifestyle preferences either way.
Sims who live a Health Food Nut Lifestyle are devoted to eating nutrient-filled foods! To acquire or maintain this Lifestyle, eat healthy foods and harvestables while avoiding Quick Meals, desserts, or anything that may seem unhealthy!
