Why does extra mature cheddar have a Nutri-Score of D and which nutrients lower its grade?

The D rating stems mainly from its high saturated fat (22 g) and relatively high salt (1.8 g) values, which generate 18 negative points in the Nutri-Score algorithm, outweighing the positive protein score of 7 points.

How does the high saturated fat and salt content in extra mature cheddar affect a heart‑healthy or hypertensive diet?

Elevated saturated fat can raise LDL cholesterol, and added salt contributes to higher blood pressure, so people managing heart disease or hypertension should limit portion sizes and balance the cheese with lower‑fat, low‑salt foods.

Is extra mature cheddar suitable for low‑carb diets such as keto or paleo, and can vegetarians eat it?

Its very low carbohydrate level (0.5 g) makes it keto‑friendly, but because it is made from cow's milk and often uses animal rennet, it is not suitable for vegetarians.
