The Budwig protocol (or Budwig diet) is an anti-cancer diet developed by Budwig in 1952. The diet is rich in flaxseed oil, mixed with cottage cheese and milk, and meals high in fruits, vegetables, and fiber. The diet also avoided sugar, animal fats, salad oil, meats, butter, and especially margarine. She claimed that within 3 months, some patients on this diet had smaller tumors, some had no tumors left, and all felt better.[1][2][3]
Evidence for the effectiveness of the Budwig diet is limited as most research has only been done on cell culture studies and experiments on rats and mice with inconsistent results. Such studies suggest that flaxseed may possibly be beneficial for cancers in mice. Some small studies have been done in humans which suggest flaxseed may be beneficial in reducing the risk of prostate cancer but more studies would be necessary to confirm any effects.[1] There is no reliable evidence available for the effectiveness of the full Budwig protocol.
