Are nuts a good source of protein?



I first had this argument just a couple of years into my PT career.

And as you can see from the picture, for every 100g plain pea nuts you get 26g protein.

Which is only just a few grams short of a chicken breast for the same weight.

Which sounds great! Good protein source.

But surely a better way to look at the viability of nuts as a protein source is to look at the kcals of energy you also consume when eating them.

In this case, you ingest just under 22kcals for every gram of protein recieved, whereas you get 5kcals for every gram of protein from the chicken breast.

And that is because for 1 every gram of protein you get from a nut you also consume around 2 grams of fat.

Making them very calorific.

And that’s fine. They are high fat, near on 50%, and very nutritious.

But were not talking about the nutritional density. Both are nutritious.

This is a comment on the efficiency of nuts as a protein source. Not on how nourishing and healthy they are.

I eat 200g protein per day. If that was all to come from nuts I’d be eating 4330kcals. From chicken breast I’d be eating 986kcals.

In my opinion, nuts are a great nourishing fat source first, with a little side line in protein.

But should always be considered as a fat source as they are primarily made up of fat and therefore gram for gram very calorific.

We gain fat mass when we over eat, calorie surplus, even if that’s from healthy food.

Nuts have the ability to add hundreds of calories to you diet if you eat alot of them, which means it’s easier to over eat and gain weight.

Therefore, be aware of the amount you are eating and consider them a source of fat, not protein, as there are much more calorie efficient ways of getting your protein requirement than relying on nuts.
