What would you prefer: a bowl of oats sweetened with honey, or a cone of deep-fried french fries?

It doesn’t really matter. Whatever you choose, your brain wants the oily, starchy fries. Or a doughnut. Or a chocolate-chip biscuit.

There seems to be something unique about these ‘combination’ foods, which mix fat and carbohydrates in a way rarely seen in nature.

They overstimulate our brain, which unconsciously craves them, no matter our conscious food preferences. Possibly, this craving is so strong it may lead to addiction.
