Johanna Budwig (30 September 1908 – 19 May 2003) was a German biochemist and author. She developed the Budwig protocol, a supposed anti-cancer diet, in 1952. The diet is rich in flaxseed oil, mixed with cottage cheese and meals high in fruits, vegetables, and fiber. The diet also avoided sugar, animal fats, salad oil, meats, butter, and especially margarine.
Budwig claimed that within 3 months, some patients on this diet had smaller tumors, some had no tumors left, and all felt better. However, there is no reliable evidence supporting Budwig's claims, and no scientific evidence that the Budwig diet helps people with cancer.
