Every week, it seems like a new nutrition fad pops up. But what is the actual scientific data on these fads when it comes to improving your health?

Take juicing, for example. It’s certainly a healthy option in theory but when researchers scoured the evidence, they found that juicing with pulp removal actually concentrates the calories.

Since getting a degree in nutrition, I’ve come to the conclusion that we are just beginning to understand the field of nutritional science. So if something sounds too good to be true, it probably is.

I do think there is no one-size-fits-all approach to nutrition, and you should find what works for you. That being said, following a low sugar, low carb, high lean protein diet works for me.
