They are the divisive snack you either love or hate. Twiglets are a staple at many British get-togethers - but did you know that some diet gurus class them as somewhat of a health food?Described as a 'healthier' alternative to crisps, the sticks were first created in 1929, when a manager at a biscuit firm added brewer’s yeast to some leftover Vitawheat dough, resulting in a Marmite-like flavour.Ovenbaked rather than fried, nutritionists say they are far less fatty than other packet snacks. What's more, they are 80 per cent wholegrain, as opposed to the refined carbs in most crisps. But some natural food advocates have warned that the addition of unfamiliar ingredients - such as chemicals to improve texture - cancel out any supposed benefit. And, despite being made with nutrient-heavy yeast, experts say Twiglets do not deliver the same vitamin B12 boost as Marmite. So should we be swapping our crisps for Twiglets? Here, two dieticians give their verdict on the twiggy snack. Twiglets contain roughly the same bowel-boosting fibre as a large apple, diet experts sayAre Twiglets healthy? A pack of Twiglets - made from wholewheat flour, vegetable oils, yeast extract, pepper and two flavourings - is a relatively slimming choice, experts say.One packet has just 97 calories, half a gram of saturated fat, barely any sugar and a large pinch of salt. You'll struggle to find a lower calorie snack of a similar vein, with most crisps totalling around 130.But the most notable benefit lies with the impressive quantity of both fibre and protein, according to dietitian Helen Bond. 'Wholewheat flour contributes a hit of fibre which can slow the release of energy and keep you fuller for longer.'Studies show that diets high in fibre can prevent bowel cancer and benefit the millions of vital gut microbes that are important for everything from heart health to the immune system.Bond says one pack provides about a tenth of your daily recommended fibre intake - almost three grams, and roughly the same amount as in a large apple. 'Compared with many crisps and cheese-based snacks, they are also relatively low in saturated fat, containing just two per cent of the daily 20g saturated fat limit,' she adds.Saturated fat is the type known to increase risk of a build up of 'bad' cholesterol, which can damage arteries and trigger heart attacks and stroke.Twiglets also boast protein, which is unusual for a wheat-based snack.'They have 2.9g protein per pack, which is roughly half the amount in a medium egg,' says Bond. This will further add to the fullness effect, she adds. Another nutrient boost comes from the B vitamins that are abundant in yeast. These are vital for increasing energy levels, as they help cells convert food to fuel.However, unlike Marmite, Twiglets are not fortified with vitamin B12 - which up to a third of older adults are lacking - meaning there's minuscule amounts.
