Why does Seriously good mayonnaise receive a Nutri-Score of D, and which nutrients are responsible for this rating?

The Nutri-Score algorithm penalises high energy, saturated fat and salt; this mayonnaise scores 7 points for 2654 kJ, 5 points for 5.3 g saturated fat and 4 points for 1 g salt, giving a total of 16 negative points that place it in the D grade.

How does the fat and salt content in this mayonnaise affect a diabetic or hypertensive diet?

The low sugar content makes it less problematic for blood‑glucose control, but the very high fat and calorie density can contribute to weight gain, while the 1 g of salt per 100 g may increase sodium intake for hypertensive individuals, so it should be used sparingly.

Is the mustard seed ingredient a concern for people with mustard allergies?

Yes, mustard seeds are listed as an allergen in the product, so anyone with a mustard allergy should avoid this mayonnaise.
