if you've got the genes for hypertension, then salt is something you should be careful of. if you've got the genes for type 2 diabetes, saturated fat and sugar are your problem. so what we do is we relate those conditions or those genetic risks to those macronutrients in food. time to hand over my dna, which i've been assured will be destroyed straight after it's been analysed. and we load that into the cartridge, and then we load the cartridge into one of the nudge boxes. it looks like a coffee machine. an hour later, i have my results. it looks like i really shouldn't be having salt or much saturated fat. dangerfrom salt medium, calories medium. these aren't actually the results i expected. chris, i'm glad you're to hand. obviously you don't have the obesity risk,
