The average person eating a
modern western diet of
processed food consumes a LARGE quantity of fructose without even thinking
about it from all of the soft drinks (high fructose corn syrup typically), sweetened juice drinks, orange juice,
processed junk
foods such as cakes and candies, as well as the HFCS that's added to store - bought salad dressings, breads and cereals, and even condiments like ketchup.
For those of you who live in a cave and have no idea what I'm talking
about (pun totally intended), the paleo diet restricts
modern processed foods, grains, legumes, and dairy.
