We're all on the lookout for little ways to make our lifestyles that bit healthier – and the good news is you don't have to completely overhaul your eating habits to feel some benefits. Just minor tweaks to your usual diet can cut excess calories, boost your intake of vitamins, minerals and fibre, and reduce the amount of sugar and saturated fat you're consuming. Try these easy food swaps for a health boost.

Note: For this feature we used the UK’s official McCance and Widdowson’s food composition tables. A list of Nutrient Reference Values (formerly known as Recommended Daily Allowances) for vitamins and minerals can be found here. 

One of the easiest ways to cut calories from carbs is to swap standard wheat tortillas for lettuce. Pretty much any of your favourite meat or veggie fillings will work well cased in these lighter wraps, but for something filling and flavoursome try slow-cooked pork mince flavoured with ginger, soy and fish sauce.

Cut carbs and calories (and sneak in an extra veg portion) by swapping standard rice for cauliflower rice. To make, roughly chop a de-leafed cauliflower and blitz it in a food processor. The resultant “rice” can be microwaved for about three minutes, or patted into a baking tray, drizzled with oil and roasted for 12 minutes at 200°C (400°F). For something punchier, try a kheema-style spiced cauliflower rice.

Whizz frozen banana slices in a sturdy blender for soft scoop 'ice cream' that has no added sugar and less than 100 calories in two scoops (plus it counts as one of your five-a-day). Compare that with Ben and Jerry’s Cookie Dough, which has 235 calories per two scoops, along with 8g of cholesterol-raising saturated fat (that's 40% of a woman’s daily recommended limit).

Top a slice of fresh cucumber with cream cheese and smoked salmon for a spin on the traditional cocktail blini that’s crunchy, fresh and has around 20 calories fewer than the flour-based version.

Nutritional yeast is a low-sodium, slightly cheesy seasoning that can be used as a substitute for salt. Just 2tsps supplies more than 50% of the NRV* of vitamins B1, niacin, B6 and folic acid, as well as 100% or more of the NRV of vitamin B2, B12, zinc and vitamin D. (*NRV = Nutrient Reference Value, the replacement term for Recommended Daily Allowance.)

In a sandwich made with 45g of cheese, you’ll save 33 calories by going for brie compared with Cheddar. Brie is a bit lower in calcium, but it’s richer in folate, which can help fight fatigue.

Peanut butter is good, but tahini, made with sesame seeds, is an even better spread for your bread. A 15g tablespoon (100 calories) provides 57mg of magnesium, compared with 27mg in peanut butter. Magnesium is important for nerves, muscles and energy and the average intake in women aged 19-64 is only 238mg daily, versus a daily recommendation (NRV) of 375mg.

Upgrade the nutritional value of your standard caesar salad by swapping pale, crunchy iceberg lettuce for deeper green baby kale. Kale is top of the crop when it comes to leafy greens – an 80g serving has 420mcg or 52% of the NRV of vitamin A (needed for the immune system), along with 13% of the NRV of bone-friendly calcium, and 10% of the NRV of anaemia-protective iron.

A 15g level tablespoon of chocolate spread, like Nutella, on toast has 71 fewer calories and 3tsps less sugar than a Snickers bar. Use wholemeal toast and you’ll also get 2.6g fibre, making this a more satiating sweet snack than a chocolate bar too.

Topping spiralised courgette instead of traditional spaghetti with beef bolognese sauce slashes the calories in a typical serving from around 700 to nearer 300. Courgetti is available in many supermarkets if you don’t have the spiralising equipment to make your own.

Adding a small handful of almonds to your salad gives that satisfying crouton crunch, but with higher amounts of protein, essential fats and fibre, plus a decent dose of magnesium, potassium and iron.

Swap a 150g serving of roast sweet potatoes for the same size serving of roasted butternut squash to save around 115 calories. Butternut is less carb-heavy, but an equally good source of vitamin A.

Mushrooms produce vitamin D when they are in bright sunshine – just like we do in our skin on a sunny summer day. Compared with standard mushrooms (grown in the dark) with only a trace of vitamin D, UV-exposed mushrooms, such as Tesco chestnut mushrooms have 5mcg vitamin D (100% of the NRV) in a 4 to 5 mushroom serving.

Zero-percent-fat natural Greek yogurt is strained and has a higher protein content than regular yogurt, plus a thick, creamy texture. A 100g serving has just 57 calories – that’s the same as in standard zero-fat natural yogurt, but you’ll find the Greek option curbs your appetite better and fills you up for longer.

Switching your usual breakfast cereal for a bowl of All Bran is an easy win for your digestive health. A 40g bowl has 11g fibre, way ahead of the same size bowl of bran flakes with 4.2g. Fibre reduces your risk of colon cancer and builds healthy gut bacteria, but on average we only get about 18g of the 30g-per-day recommendation.

Red peppers don’t just look prettier than green – you'll also be getting more vitamin A by choosing the more vibrant veg. One 160g red pepper provides 20% of the daily recommendation (NRV) of vitamin A, which is needed for a healthy immune system, eyes and skin. A green pepper has less than half this, though both are excellent sources of vitamin C.

Check the strength of your favourite cider. A higher alcohol (6-8.5%) vintage brew has around 386 calories per pint, while a standard dry cider, with 4.7-5-5% alcohol, such as Strongbow, has only around 200 calories per pint.

A tortilla doubles as a lower calorie and lower carb alternative to a dough base – top with spinach, mozzarella and egg for an approximately 500-calorie pizza.

Old-school squidgy malt loaf is a healthier sweet snack than most cereal bars – for example, a 30g Jordans Blueberry Frusli bar has 113 calories and 9.9g of sugar, while a 30g Soreen Lunchbox Loaf (no butter) has 91 calories and 5.1g of sugar. Malt loaf also has a medium Glycaemic Index, so it won’t send your blood sugar soaring.

Prawns are a satiating, low-fat source of protein, so with tomatoes and mustard seeds – not lots of oil and cream ­– a prawn curry is a much better choice for your waistline than a typical chicken tikka masala or korma.

Whipping cream (110 calories and 7.3g saturated fat per 2tbsps) can be used wherever a recipe calls for double cream (140 calories and 9.4g saturated fat per 2tbsps). It’s worth making the switch, as you’ll barely notice any difference in taste or texture.

Switch yellow onions for red to get an extra boost of antioxidants. Researchers at the University of Guelph in Ontario, Canada showed red onions were the most potent at killing cancer cells in the lab, because they have high levels of both quercetin and anthocyanins (the red colour), which work together in scavenging rogue molecules. These tests need to be repeated in human studies.

Can’t shake a sweet craving? Go for a Jaffa cake, with only 46 calories, versus the 83 calories in a chocolate digestive. Jaffa cakes are higher in sugar though, so aim to limit yourself to one or two at most.

Velvety avocado works brilliantly as a mayo alternative in wraps, salads and sandwiches, keeping chicken and tuna fillings succulent. You’ll also save 136 calories per serving (2 tbsps full-fat mayo = 193 calories; 2tbsps smashed avocado = 57 calories).
