I have been taking chia seeds for quite a while now. They're very nice mixed with unsweetened fruit purée. I do hope they live up to all these claims!
Omega-3 Fatty Acids
Chia seeds are rich in polyunsaturated fats, especially omega-3 fatty acids. Chia seeds' lipid profile is composed of 60 percent omega-3s, making them one of the richest plant-based sources of these fatty acids -- specifically, of alpha-linolenic acid, or ALA. The omega-3s in chia seeds can help reduce inflammation, enhance cognitive performance and reduce high cholesterol.
Fiber is associated with reducing inflammation, lowering cholesterol and regulating bowel function. Chia seeds are an excellent source of fiber, with a whopping 10 grams in only 2 tablespoons. That is one-third of the daily recommended intake of fiber per day.
Chia seeds are rich in antioxidants that help protect the body from free radicals, aging and cancer. The high antioxidant profile also helps them have a long shelf life. They last almost two years without refrigeration.
Two tablespoons of chia seeds contain 18 percent of the DRI for calcium, 35 percent for phosphorus, 24 percent for magnesium and about 50 percent for manganese. These nutrients help you prevent hypertension and maintain a healthy weight, and are important for energy metabolism and a part of DNA synthesis.
Fewer cravings between meals
Satiety is the feeling of being full and satisfied, which helps lower food cravings between meals. The combination of protein, fiber and the gelling action of chia seeds when mixed with liquids all contribute to their satiating effects.
Chia seeds contain no gluten or grains. Therefore, all of the nutritional benefits of chia seeds can be obtained on a gluten-free diet.
A study published in the "British Journal of Nutrition" showed that chia seeds as a dietary fat source can lower triglycerides and cholesterol levels while increasing HDL or "good" cholesterol. The study also found that when substituting chia seeds for other fat sources, such as corn oil, the ALA was able to prevent high triglyceride levels and reduce central obesity.
Blood Sugar Regulation
Chia seeds can play an important role in regulating insulin levels. They can reduce insulin resistance and decrease abnormally high levels of insulin in the blood.
[I read an article about chia where the author states that taking dry chia seeds followed by liquids can be dangerous, as the seeds are sticky and swell, possibly causing occlusion of the oesophagus. If you decide to add chia seeds to your diet, it would be better to mix them with liquid or fruit purée and let them swell before ingesting the mixture, just to be on the safe side...]
