Flaxseed
Flaxseed or flaxseed oil has become a ‘buzz word’ nowadays and seems to promise great strides in increased health for many. But before putting it in your daily diet, please take note there are some possible side-effects:
Based on animal studies, overdose of flaxseed may cause shortness of breath, rapid breathing, weakness, or difficulty walking, and may cause seizures or paralysis. Theoretically, flaxseed ( not flaxseed oil) may increase the risk of cell damage from a reaction called oxidative stress. Studies report conflicting results in this area. Based on one study, flaxseed or flaxseed oil taken by mouth may cause mania or hypomania in people with bipolar disorder. In theory, the laxative effects of flaxseed ( not flaxseed oil) may cause diarrhea, increased number of bowel movements, and abdominal discomfort. Laxative effects are reported in several studies of people taking flaxseed or omega-3 acids. Large amounts of flaxseed by mouth may cause the intestines to stop moving (ileus). People with diarrhea, irritable bowel syndrome, diverticulitis, or inflammatory bowel disease (Crohn’s disease or ulcerative colitis) should avoid flaxseed due to its possible laxative effects. Nausea, vomiting, and abdominal pain are reported in two individuals shortly after taking flaxseed products by mouth; these reactions may have been caused by allergy.
