Fruit as a food choice comes with a caveat: How much is too much?

Fruit is widely regarded as a healthy food — but is there such a thing as too much? In a recent video, a Harvard researcher sets out to explore the nutritional nuances of this popular food group.

Nick Norwitz — who has a PhD in metabolic health and is currently finishing his medical degree — weighs the benefits and risks of consuming large quantities of different types of fruit. (See the video at the top of this article.) "All fruits, in moderation, can fit into a healthy diet." "Most of the fructose in the American diet doesn’t come from fresh fruit, but from added sugars like high-fructose corn syrup and table sugar." "Any food, if consumed in very high levels, can lead to an imbalance in overall diet." Melissa Rudy is senior health editor and a member of the lifestyle team at Fox News Digital.

"The blanket statements that fruit is ‘natural and therefore healthy’ and ‘contains sugar and therefore unhealthy’ are both harmful oversimplifications," he told Fox News Digital.
