The Side Effects of Chia

Chia, also known as Salvia hispanica, is a flowering plant native to Central and South America. Chia seeds were important to ancient Aztec and Mayan diets and medicine, as well as Aztec currency. Chia seeds are a source of omega-3 fatty acids and antioxidants. They can be eaten raw, ground and baked into foods. For example, 33 to 41 g per day may be ground and incorporated into bread, which may help prevent cardiovascular disease, states Wellness.com. However, as with any substance, side effects may occur. Consult your physician prior to using chia seeds.

Prostate Cancer Risk

Chia contains a high amount of alpha-linolenic acid, and some empirical investigations indicate that large amounts of alpha-linolenic acid in the diet may increase your risk of developing prostate cancer, warns the University of Maryland Medical Center. Therefore, if you have prostate cancer or are at high risk -- such as having a family history of this disease -- avoid eating large amounts of products that contain alpha-linolenic acid, such as chia. These research findings, however, have not been replicated in other studies; thus, further investigations are necessary to support these preliminary findings.

Anti-coagulant Effects

Omega-3 fatty acids are associated with many health benefits. Yet, despite such marketed benefits, omega-3 fatty acids, as those found in chia seeds, are natural blood thinners. Their anti-coagulant properties work by decreasing the "stickiness" or aggregation of platelets that are needed for clotting. Thus, if you are taking blood-thinning medication, such as aspirin or warfarin -- also known under the brand name of Coumadin -- you should first speak to your physician before taking chia supplements. Additionally, if you are scheduled for an upcoming surgery or other medical procedure where blood loss may occur, speak with your physician before considering chia as a supplement. If you already are using chia supplements prior to an upcoming procedure, stop consuming chia and notify your doctor about your use of chia.

Hypotension

Chia seeds can affect your blood pressure. Specifically, chia is associated with hypotension or low blood pressure, according to a 2007 study by V. Vuksan and colleagues as reported in the "Natural Standard Professional Monograph" review. Discuss chia with your doctor if you have blood pressure problems or heart disease.

Gastrointestinal Effects

Chia seeds contain fiber, so gastrointestinal side effects may occur after eating chia products. If you experience such side effects, reduce the amount of chia you consume daily.
