Budwig diet

Is it safe?

Plant-based foods contain only minimal amounts of Vitamin B12. An ovo-lacto-vegetarian diet includes eggs and cheese, two important sources of Vitamin B12, although these foods cannot meet a greater need. Since a vegetarian diet is rich in folates, the effects of Vitamin B12 deficiency can often be masked until neurological symptoms manifest 14. For this reason, those who pursue a vegetarian diet or another kind of diet such as Budwig should make sure they take Vitamin B12 supplements to ensure an adequate supply 15.

Adverse events

The hull of flaxseed contains a mucilage that binds water in the intestines, expands and has a laxative effect. As a result, adequate hydration is necessary.

Flaxseed contains cyanogenic glycosides which can release hydrocyanic acid after hydrolysis in the intestine. When flaxseed is consumed in normal quantities, the resorbed quantity of hydrocyanic acid is not considered to pose a threat 16,17.

Allergies to components found in flaxseed have been reported but are very rare 18.

Contraindications

Flaxseed is contraindicated in patients with ileus or stenoses in the gastrointestinal tract.

Interactions

Flaxseed can absorb orally administered medication and thus have an impact on its efficacy. Consequently, flaxseed (not flaxseed oil) should only be taken a few hours before or after taking medication by mouth to prevent decreased absorption. 7

Warnings

Current knowledge indicates there is a positive correlation between the energy density of a diet and body weight, which means that a high-protein diet can lead to obesity. Medical societies recommend that weight-control measures take into account the protein content of the diet.
