Sourdough is a plant‑based bread made from wheat and rye flours, water and a pinch of sea salt, sold by Marks & Spencer in the United Kingdom. It carries a Nutri‑Score of A and falls in NOVA group 3, offering low fat (0.8 g), low sugar (1.7 g) and very low salt (0.12 g per 100 g) while providing 9.4 g of protein and 3.1 g of fiber per 100 g. However, it is not a whole‑grain product, contains gluten and includes added minerals such as calcium carbonate, so it may not suit gluten‑free or low‑mineral diets.
