Aztec warriors treasured chia seeds for their medicinal properties, and many of these alleged properties are now being confirmed by contemporary studies. Below is a list of the health benefits attributed to chia seeds and the research that reinforces them.
Rich in essential fatty acids
One serving (2 ounces) of chia seeds contains approximately 11 grams of fat. Of these, 1 gram is saturated fat, while the remainder is comprised of essential polyunsaturated and monounsaturated fats, including omega-3 and omega-6 fatty acids. In fact, according to a 2005 study published in the Nutrition Research journal, chia seeds are the greatest plant-based sources of alpha-linolenic acid (ALA). ALA is an essential omega-3 fatty acid that has been known to prevent cancer, lower the risk of cardiovascular diseases, reduce cortisol levels and much more. Moreover, chia seeds and other foods that contain optimum omega-3/omega-6 balances are known to improve brain function, since our brains are built from the same fats.
Excellent source of protein and energy
According to chia expert Dr. Wayne Coates, chia seeds are comprised of at least 20 percent protein. This protein is high-quality; the amino acid score for chia seeds is 91 out of a possible 100, which dwarfs the scores of other protein-packed seeds such as flax seed. This near-perfect amino acid profile makes chia seeds an excellent 'complete' protein source for vegetarians, as well as a potent energy source for bodybuilders and athletes. In fact, according to The Magic of Chia author James Scheer, chia was once called the "Indian Running Food" due to its significant energy-boosting properties.
Help treat diabetes
Several studies have confirmed the long-held belief that chia seeds can help treat diabetes. One January 2009 study published in the British Journal of Nutrition, for instance, found that chia could normalize insulin resistance in diabetic rats while reducing the fat and cholesterol in their blood. These findings reinforce the results of an earlier 2007 study for the Diabetes Care journal, which concluded that chia improved "major and emerging cardiovascular risk factors in type 2 diabetes" in 20 patients.
These impressive results are often attributed to the fact that chia seeds form a gel when ingested, which slows the breakdown of carbohydrates, allowing the digestive system to process sugar in a more gradual and stable manner.
Packed with nutrients and minerals
According to the information supplied by NutritionData, 1 ounce (28 grams) of dried chia seeds contains 18 percent of our RDI of calcium, 27 percent of our RDI of phosphorus, 30 percent of our RDI of magnesium and varying quantities of zinc, copper and potassium. 1 ounce of chia seeds also contains a whopping 42 percent of our RDI of dietary fiber, making them an effective natural cure for constipation.
Chia seeds are easy to find online and in health food stores, and they boast a long shelf life. Though they are usually eaten "as is," often as a snack in-between meals, some people like to add them to their morning smoothies or breakfast cereals.
