Oscar Umahro Cadogan started working with food after suffering from serious GI dysbiosis and delayed allergic reactions to numerous foods for several years. At the brink of getting full-blown inflammatory bowel disease, he managed to turn his life around using ideas at the heart of integrated/complementary medicine. A thorough regimen of dietary changes, botanicals, I-V antioxidants, and probiotics helped him get well within a year.

Having experienced the lack of information on how to eat while ill, both in terms of nutrition and from the perspective of gastronomy, he decided to work at unifying these two areas, which are often seen as incompatible. He has received much credit and acclaim for his work as a chef bridging the gap between nutrition and gastronomy from other chefs, patients looking to use food for prevention as well as a healing agent, and medical professionals using integrated/complementary medicine.

He had his first cookbook published in Denmark in November, 1999 with 80 recipes all suitable for allergics and patients with inflammatory bowel diseases, as well as those interested in cooking extremely tasty and healthy food and is working on his next cookbook with recipes specifically for children.

Several recipes from both books are featured in his column "Healthy Recipes". He often appears on Danish national TV and writes for several Danish newspapers and magazines on issues such as nutrition, the declining quality of industrially produced foods, superfoods, and the idea of using food as a healing factor. He has also worked as a guest chef in several Danish restaurants, taught cooking classes in healthy cooking, done consulting for producers of foodstuffs, and lectured about the importance of eating a diet in accordance with one's body's needs based on natural and wholesome foods. He is also in the middle of getting his own range of extremely pure, healthy, and tasty foodstuffs put into production for the Danish market.
