How DNA-testing kits are becoming big business

The latest health and fitness trend involves taking a DNA test to find out more about how our bodies respond to different types of food and exercise. But how accurate and effective are these kits?
Fitness fanatic Mandy Mayer, 56, exercised several times a week but felt like she'd hit a plateau.
Her personal trainer suggested she try a DNAFit test, which tests the body's genetic response to key foods and exercise.
"I jumped at the chance," she says. "I thought I'd love to have that kind of knowledge."
After sending off a swab of her saliva, she received a report on her fitness and diet in January. She was impressed.
"I was like 'wow'. They told me I don't tolerate caffeine and refined foods very well, and I respond better to endurance training than anything else."
Three months later and she has dropped from a size 12 to a size 10 and lost several kilos. She attributes her leaner figure to understanding more about her genetic code.
"Without a shadow of a doubt it was down to the test," says Mandy, who lives in Market Harborough, Leicestershire.
"It's made me follow the right training and make little changes to my diet."
A growing number of start-ups, such as 23andMe, FitnessGenes, UBiome, DNAFit, Orig3n and Habit, are moving into this space, promising that mail-order genetic tests can change your life for the better.
