Isn't it hard for everyone to read ingredient lists when dieting? ㅠㅠ

Lately, I've been trying to manage my diet, so I make sure to check the nutrition facts whenever I buy snacks or groceries, but it gives me a headache every time I look at them...

I thought I would just need to check the calories, but when I tried to meticulously check the sugar, sodium, and carbohydrate ratios as well, I had no idea what on earth it all meant. Plus, the standards vary from product to product, so it was really hard to choose.

What do you all consider most important when choosing a product?
