We’re always a little skeptical of medical claims found online, so we did a quick Google search and found several other articles which do support the health benefits of eating lemons and lemon peels in the fight against cancer – and even in the potential prevention of cancer.

Vitamin B6
Vitamin B6 plays a part in such major functions including movement, memory, energy expenditure and blood flow. Vitamin B6 helps the body to maintain a healthy nervous system, to make hemoglobin that carries oxygen in red blood cells throughout the body, to provide energy from the food that we eat, to balance blood sugar levels, to act as a natural pain treatment, to boost mood and also to create antibodies that our immune system uses to protect us.

Folic Acid
Folic acid is well recognized for its value in the prevention of certain birth defects. Many believe that women who consumed more folic acid had a significantly reduced risk of developing high blood pressure (hypertension). Folic acid acts by helping the body produce and maintain new cells. In particular, red blood cell formation is dependent upon adequate levels of this vitamin. Folate may also help cells resist changes in their DNA associated with the development of cancer. Source:
