Quorn Classic Burgers

Two burgers (180g), £2.50, most supermarkets

Per 100g: Calories, 182; saturated fat, 3.2g; protein, 18g; sugar, 1.9g; salt, 1.5g; fibre, 3.9g Quorn products are made with mycoprotein — a protein from a fungus grown in sterile fermentation tanks. These burgers have less than half the saturated fat of beef burgers and are a good source of gut-healthy fibre — one has more than a slice of wholemeal bread (meat has none).

But like many plant proteins, it’s not high in iron — needed for energy — and doesn’t provide vitamin B12, important for a healthy nervous system. A Quorn burger has a quarter of your daily maximum salt, twice as much as a supermarket beef burger.

TASTE: Slightly musty flavour.
