Chia seeds and flax seeds nutrition allows for their many uses and benefits, which include:

  • An excellent supply of omega-3 fatty acids: Omega-3 fats improve your health by assisting in reducing inflammation, which otherwise has the potential to cause disease. The omega-3 found in both chia and flaxseed is called alpha-linolenic acid (ALA). Although fish and other animal foods provide the majority of omega-3 fats, these seeds are among the best plant sources of these vital fats. 
  • Rich in antioxidants: These seeds are quite high in antioxidants. Consuming antioxidant-rich foods helps shield our cells from disease-causing free radicals. Thus, regularly consuming chia and flax seeds can help in the prevention of diseases.
  • Filled with fiber: Almost 80% of the carbohydrates found in these seeds are in the form of fiber. Fiber acts as a prebiotic that helps feed the good bacteria in your stomach, promoting a healthy digestive system and warding off digestive illnesses including irritable bowel syndrome and constipation. It also aids in weight control by extending the feeling of fullness. 
  • Source of plant-based protein: As we know, proteins are the building blocks of the body. Those who consume just vegetarian or vegan food may find these seeds to be a beneficial source of protein.
  • Improve heart health: Both chia and flaxseed improve heart health by lowering cholesterol and blood pressure levels along with reducing inflammation. 
  • Stabilize blood sugar: High-fiber content in these seeds prevents blood sugar spikes and helps in managing insulin levels and diabetes. 
  • Helps in weight loss: Both flaxseed and chia seeds are good for gut health and effective at controlling appetite, which aids in weight loss.
  • Cancer-fighting properties: Both these seeds have anti-cancer properties that reduce the growth of cancer cells in breast, colon, cervical, and prostate cancer.
