Chia Seed Side Effects
There are very few side effects associated with chia seeds. There has been some conflicting research about the effect of chia seeds on prostate cancer. A study done with ALA and prostate cancer (8) showed that this fatty acid could increase the risk of prostate cancer, but this study was later shown to have some bias.
And according to a recent study in 2010, ALA not only did not increase prostate cancer risk, but actually decreased the risk in participants. (9)
Occasionally some people may experience stomach discomfort when consuming chia seeds especially in large amounts due to the high fiber content. As with any food, eat in moderation and always drink plenty of water unless soaking your seeds.
