Nutri-omics is the study of how diet affects many other processes in our bodies. New research is looking at the role of diet in epigenetics – the science of how chemical signals can switch your genes on and off.

We know that foods like nuts and broccoli containing folic acid, betaine and choline could be crucial and we are also looking at metabolic markers in our blood to see if we can use these rather than questionnaires to measure what nutrients and vitamins we eat. Certain genes determine if we can taste certain foods or find them unpleasant.

Genes may control how we break down starch and so have an effect on our weight. Other research involves comparing our diets to what bacteria we have in our guts- the so called microbiome. These 100 trillion bugs play an important part in our lives and can determine if we are fat or thin- so look after them.
