Strict diets such as macrobiotic or Vegan diets do not contain dairy or animal products. This can stop you getting enough nutrients for your body to work properly. You can also lose a lot of weight.
You might already be weak and underweight if you have cancer. So you need to take in more calories than usual to cope with the disease and treatment.
A limited diet can have serious harmful effects on your health, especially if you follow it instead of having conventional medical treatments.
You might not get enough:
In some of the earlier, very strict, macrobiotic diets people ate nothing but whole grains. This caused severe malnutrition and sometimes even death.
We don’t support the use of macrobiotic diets for people with cancer. But it is completely up to you whether you want to use complementary or alternative therapies. It is important to talk to your cancer specialist about any complementary or alternative treatment that you want to try.
