GUT BACTERIA BOOST

King Soba buckwheat ramen with Zesty Ginger miso & Tofu, 190g, £3.59, planetorganic.com Per 100g: Calories, 80; saturated fat, 0.2g; protein, 3g; fibre, 2.3g; sugar, 0.6g; salt, 0.72g CLAIM: ‘Gluten-free. Buckwheat may have prebiotic properties and can lower blood sugar.’ EXPERT VERDICT: There are two servings in each pack of these noodles, which are made with buckwheat — a nutritious, gluten-free wholegrain.

A good source of protein and fibre, wholegrains are good for gut and heart health and, because they take longer to digest, should help to keep you feeling fuller for longer. Early studies suggest buckwheat may have prebiotic properties (that is, it can help to feed gut bacteria), but more research is needed.

Tofu is a source of protein, though you will only get a tiny amount here. There is no added sugar but 40 per cent of your daily salt limit. TASTE: Slim noodles, tasty broth. 4/10
