Half of Brits are confused about the right diet, with a quarter ditching entire food groups following a funny tummy.
Research revealed 29% avoid anything that causes bloating and 28% stay clear of items that trigger stomach cramps.
As a result, 38% stick to the same safe meals, missing out on a more varied diet as a result.
And although 30% believe lactose-free products are healthier, seven in 10 have never added any to their shopping basket.
Rachel Campbell, from Arla, which commissioned the research to launch its LactoFREE range, said: “Our research shows we’re a nation who are missing out on a range of delicious meals.
“Whether you’re lactose intolerant or simply want to live your life without lactose, you should never feel restricted by your diet.”
Many want to make food choices that lead to feeling better physically (48%) and mentally (25%).
But 52% feel confused when it comes to getting nutrition and diet right.
It also emerged 54% were unaware of the difference between dairy-free and lactose-free options.
And 71% didn’t know lactose-free products do contain dairy, just without the lactase.
Nine in 10 feel it’s important to maintain a healthy gut.
But 64% were unaware lactose-free products provide the same nutrients (like calcium and Vitamin D) as dairy products.
While 30% think lactose-free products are strictly for those who are lactose intolerant.
Nutritionist Rhiannon Lambert said: “Lactase is the body’s own enzyme that breaks down lactose into glucose and galactose.
“This means they can be absorbed through the intestinal wall and into our bloodstream.
“Those with a lactose allergy or intolerance may feel discomfort if lactose isn’t broken down into galactose and glucose.
“If you continue to feel discomfort after eating certain food products, it’s always best to speak with a health professional to create a bespoke dietary plan.”
