Those of you who have had nutritional consultations with me know that I would like you to include wasabi in your diets. Wasabi is a member of the brassica family, along with watercress, and a watercress farm in Dorset has now started growing it. Wasabi has many nutritional benefits. It can fight bacteria, hence the traditional practice of serving it alongside raw fish. It has been found to have anti-cancer properties. It is a rich source of isothiocyanates, which activate enzymes in the liver that can detoxify potentially cancerous substances before they can damage the body. Most commercial wasabi pastes on the market only contain a tiny proportion of wasabi. I suggest you try this fresh wasabi and incorporate it into your diet.
