Why does Lightly sea salted receive a Nutri‑Score of D and which nutrients drive this rating?

The D grade stems mainly from its high fat (27.5 g) and calorie content (505 kcal per 100 g), moderate salt (0.94 g) and lack of fruit, vegetable or legume points, which together outweigh the modest fibre and protein contributions.

How does the salt content in these lightly sea salted potato crisps affect a hypertensive diet?

At 0.94 g of salt per 100 g, the crisps provide about 15 % of the recommended daily maximum; occasional consumption is unlikely to cause issues, but regular intake could contribute to elevated blood pressure for individuals monitoring sodium.

Are these lightly sea salted potato crisps suitable for a vegan or keto diet?

The snack is vegan, containing only potato, sunflower oil and sea salt, but it is not keto‑friendly because it supplies 57 g of carbohydrates per 100 g, far exceeding typical keto limits.
