Q: What are the official UK health claims for the nutrients in watercress?

Antioxidant activity – ‘where vitamin C contributes to the protection of cells from oxidative stress’. Oxidative stress occurs when there are too many free radicals in the body and not enough antioxidants to balance them. Free radicals are produced by the body during natural metabolism and especially after exercise.

Collagen/skin – ‘Vitamin C and A support the normal maintenance of our skin’, with vitamin C specifically involved in collagen formation, contributing to the skins structure and ability to repair.

Cognitive development - ‘Iron supports normal cognitive function in adults and in children it contributes to their normal cognitive development’. ‘Vitamin C has the added benefit of increasing iron absorption’.

Immune support – ‘Vitamin A, C, iron, vitamin B6 and folate all have a role in supporting the normal functioning of our immune system’, which acts to protect against harmful pathogens such as bacteria and viruses and also helps the body recognise and eliminate damaged or abnormal cells. ‘Vitamin C also supports our immune system during and after intense physical exercise’.

Reduced tiredness and fatigue – ‘Vitamin C, folate and vitamin B6 can help to reduce our levels of tiredness and fatigue’ and ‘iron has a role in normal energy yielding metabolism’.

Increased iron and its absorption and metabolism – ‘Vitamin C supports the absorption of iron’ from the watercress we eat and ‘vitamin A helps with the normal iron metabolism in our bodies’.

Musculoskeletal health – ‘Vitamin C contributes to normal collagen formation in bone’, by laying down a collagen scaffold in the bone. ‘Vitamin K also contributes to the maintenance of our bones’, by helping calcium bind to this scaffold. In addition, ‘vitamin C supports collagen formation in cartilage and calcium contributes to normal muscle function’.

Psychological function – ‘Vitamin C, folate and vitamin B6 all have a role in helping with normal psychological function’, which relates to how our minds process daily activities.

Vision – Beta carotene is converted to vitamin A in the body, ‘which supports normal vision’, allowing us to see at low light levels.

Red blood cells, clotting and blood vessel formation – ‘Vitamin C helps maintain normal collagen formation for the normal function of blood vessels’. It also ‘increases iron absorption supporting the normal formation of red blood cells and haemoglobin’, which are needed for oxygen transport in the body. ‘Vitamin K₁ contributes to normal blood clotting’, helping the body respond appropriately to injury. Together, these nutrients support healthy blood, effective oxygen transport and strong blood vessels.
