I didn't even realize that this worksheet could have some arguable healthy/unhealthy things on them, depending on personal diet / experience / view on nutrition.
I was looking at the sheets and thinking the same thing. As we learn more about health and our individual bodies we realise the is no cut and dry way to determine healthy for everyone. The cheese is another good example as so many people are intolerant to dairy. I recently watched this video, which talks about someone who cured his ailments with a carnivore diet and notes how the bread based diet of the Egyptians likely made them fat.
Yet, there is also a rare disorder where you can't digest fats and have to eat high carb instead. Imagine the ticks going the opposite way around!
I really like this balanced article.
