How to make the fat percentage look lower, while still putting accurate numbers on the label.
Because to me if the serving size is 30g and the fat content is 4g.... Well that's more than 5% fat by volume by my calculations?
BUT if you look at the small text above that you see "% of daily value" (as in TOTAL recommended daily intake... TOTAL).
Sneaky sneak is sneaky.
