“High protein” doesn’t automatically mean healthy.
I went into M&S and rated their high protein range out of 10 as a registered Nutritional Therapist… and the results might surprise you.
Some of it is genuinely brilliant.
Some of it is clever marketing.
Some of it is basically dessert with added whey.
Here’s the thing. Protein matters. It supports muscle mass, blood sugar stability, hormone production and satiety. But protein grams on the front of the packet tell you nothing about ingredient quality.
What I’m looking at is:
• Ingredient list length
• Type of fats used
• Added sugars and sweeteners
• Emulsifiers and fillers
• How processed it actually is
A 20g protein bar with maltitol, sunflower oil and flavourings is not the same as 20g protein from Greek yoghurt, eggs or chicken.
That said, we also need to be realistic. If you work in an office, travel a lot, or need something quick between meetings, pre prepared options can be helpful. It’s about choosing the least processed option available, not chasing perfection.
High protein should mean high quality.
Save this for your next food shop and tell me… which one shocked you the most?
