14 Days with Chia Seeds: Harvard doctor explains the benefits and best way to eat them

Chia seeds are tiny black or white seeds and have become a part of the morning routine for many of us. Packed with fiber, omega-3 fatty acids, protein, antioxidants, and essential minerals like calcium, magnesium, and iron, chia seeds offer a wide range of health benefits and are mostly consumed during morning hours on an empty stomach. And regular consumption of chia seeds is said to help with blood sugar regulation, heart health, bone strength, and muscle recovery. Dr. Saurabh Sethi, a gastroenterologist trained at AIIMS, Harvard, and Stanford universities in a recent post on Instagram talked about what happens when you eat chia seeds for 14 days. And he also explained the right way of consuming chia seeds.

He states that they are rich in omega 3 fatty acids. It is said that chia seeds are among the richest plant-based sources of omega-3 fatty acids, particularly alpha-linolenic acid (ALA), which plays a vital role in maintaining heart, brain, and overall cellular health. They also help reduce inflammation, regulate cholesterol levels, and support brain function and mood stability. Apart from that, consuming them daily may help in improving the condition of hair and skin.

Just 2 tablespoons of chia seeds contain about 10 gms of fiber, which is nearly 30-40 % of your daily need. This fiber supports your gut health by feeding good gut bacteria. The soluble fiber slows down sugar absorption, stabilizing blood sugar levels, while also feeding healthy gut bacteria that aid in better nutrient absorption.

He states that chia seeds can absorb up to 12 times their weight in water forming a gel that slows digestion, helps you feel full for longer and may stabilize blood sugar levels.

In this post he has mentioned that regular chia consumption can improve cholesterol and support heart health as well. Chia seeds are rich in omega-3 fatty acids with a favorable omega-3 to omega-6 ratio, which has been linked to lower blood pressure and reduced cardiovascular disease risk.

As per experts, just 2 tablespoons of chia seeds offer around 10 g of fiber (about 40% of your daily need). They also absorb 10–12 times their weight in water, forming a gel-like substance, which expands in the stomach and promotes a sense of fullness, reducing overeating. According to a study, a 12-week randomized controlled trial with overweight or obese adults consuming 35 g of chia flour daily showed a significant intragroup weight loss of about 1.1 kg, with a greater reduction in obese individuals. In summary, chia seeds can contribute to modest weight loss and waist circumference reduction, especially when consumed daily and combined with calorie counting.

As per his post, one can soak chia seeds in water, milk, or yogurt. He further adds that soaking in yogurt for at least 15 minutes is the best option, ideally overnight . This makes them easier to digest and reduces the risk of choking.

If you put chia seeds in plain water you mainly get fiber and hydration. But, when you combine chia seeds with yogurt, they become a gut health powerhouse. The fiber in chia feeds your gut bacteria and the yogurt adds probiotics. The good bacteria themselves together, that is prebiotics plus probiotics leading to more short chain fatty acids like butyrate, which reduce inflammation and strengthen your gut lining. Yogurt also gives you protein and healthy fats. It is said in research that people who eat more yogurt tend to have a lower risk of colon cancer and with the extra fiber from chia, you are giving your colon even more protection, explains Dr Saurabh. This combination also supports smoother digestion, reduces bloating, and keeps you fuller for longer, making it an ideal choice for breakfast or a mid-meal snack that fuels both body and microbiome.

He concluded the post stating that if you are prone to bloating or have IBS, start with a small amount and increase gradually.
