Chia was originally cultivated by the Aztecs in Mexico. It can be used in a variety of foods. People often use it as a topping or put it into smoothies, cereal, or energy bars, to name just a few of its uses.
There is not enough research done about how chia affects pregnancy. Eating too much chia can make triglyceride levels in the blood too high for people who already struggle with high triglycerides. Also, chia contains a lot of alpha-linolenic acid. Large amounts of alpha-linolenic may increase the risk of prostate cancer, so if you are at risk of getting prostate cancer, it is best to avoid eating large quantities of chia.
