Chia Seeds Benefits: The Omega-3, Protein-Packed Superfood

Chia seeds are frequently featured as the star ingredient in many healthy eating recipes, ranging from baked goods to protein bars, smoothies and beyond.

Why are chia seeds good for you? Apart from offering a pop of flavor and texture to your favorite foods, they also provide health perks, such as potentially helping balance blood sugar and supporting heart health.

Keep reading for a list of chia seeds benefits and potential side effects, as well as preparation instructions and simple ways to add them to your diet with some clever chia seed recipes.

What are chia seeds?

Chia seeds (Salvia hispanica) are tiny superfoods that grow on a species of flowering plant that’s in the mint family. They are native to areas of Mexico and Guatemala but are commonly cultivated in many areas in North and South America.

Chia is typically easy to digest when prepared properly and can be a very versatile ingredient that works well in a variety of recipes. Plus, the seeds offer a long list of important nutrients, including:

• fiber
• protein
• manganese
• calcium
• antioxidants
• omega-3 fatty acids

Not only that, but recent research has found that the chia seeds benefits are even greater than scientists initially realized. They’ve been found to help promote healthy skin, reduce signs of aging, support the digestive system and build stronger bones.

Where do chia seeds come from?

Originally grown in Mexico, chia has long been highly valued for its medicinal properties and nutritional value. In fact, it was even used as currency at one point.

Chia means “strength” in the Mayan language, and chia seeds were known as “runners’ food” because runners and warriors would use them as fuel while running long distances or during battle. Aztec warriors ate them to give them energy and endurance, claiming that just one spoonful could sustain them for 24 hours.

Salvia hispanica has also been used for its potent healing properties in many branches of traditional medicine for centuries. According to Ayurveda, chia seeds can help nourish the blood and promote digestive regularity thanks to their ability to absorb water in the gastrointestinal tract, forming a gel-like substance.

They can also reduce inflammation, promote kidney health and support proper hydration, according to Ayurvedic medicine.

Chia vs. flax vs. hemp

Chia, flax seeds and hemp seeds are the three most popular varieties of seeds for their crunchy texture, mild flavor and nutritional benefits. All three are rich in fiber and protein and make valuable additions to many types of diets, especially vegan or vegetarian diets.

Ounce for ounce, chia contains the most grams of fiber and is especially rich in soluble fiber, which can help lower cholesterol levels, reduce appetite and promote digestive regularity. Unlike other types of seeds, chia can be consumed either whole or ground.

Plus, it provides a good amount of several other micronutrients, including calcium, manganese and phosphorus.

How about chia seeds vs. flax seeds?

Flax is the greatest plant source of omega-3s, which is important for reducing inflammation and preventing chronic disease. Flax is also high in lignans, which are plant compounds that acts as an antioxidant and have been linked to protection against cancer and heart disease.

Unlike chia, however, flax needs to be ground up before consumption in order to maximize absorption of its nutrients.

Compared to chia and flax, hemp seeds pack in the highest amount of plant-based protein per serving. They’re also rich in magnesium, zinc and iron.

However, they contain a much higher ratio of omega-6 to omega-3 fatty acids, a nutrient that most of us get too much in our diets already. Therefore, experts typically recommend consuming hemp in moderation.

Nutrition facts

Chia is rich in protein (amino acids), fiber, manganese, phosphorus and calcium. Plus, as mentioned above, it’s a good source of omega-3s (polyunsaturated fatty acids), such as α-linolenic and linoleic acids.

Additionally, it’s rich in polyphenols and antioxidants, such as caffeic acid, rosmarinic acid, myricetin, quercetin and others. It’s also considered a low-carb food because the net carbs (total carbohydrate grams minus fiber grams) are relatively low.

Benefits

What are the benefits of eating chia seeds? Here are 12 reasons to add more of them to your diet, including because they can decrease risk for several common diseases:

1. Support healthy skin

Chia is jam-packed with antioxidants, which are compounds that fight free radical damage and prevent oxidative stress while also promoting tissue repair and protecting against skin damage.

Interestingly enough, researchers from Mexico recently uncovered that they have a total antioxidant concentration nearly two times higher than previously reported. In fact, the antioxidant activity of Salvia hispanica seeds was shown to stop up to 70 percent of free radical activity.

As one of the most high-antioxidant foods on the planet, adding some to your diet may help fight premature aging and protect the skin cells from things like ultraviolet and environmental damage.

2. Promote digestive health

Chia is loaded with fiber, squeezing nearly 10 grams of fiber into a single ounce.

Because of their rich fiber content, chia seeds benefit digestive health by promoting regularity and increasing stool frequency to prevent constipation. The fiber also acts as a prebiotic to provide fuel for the beneficial bacteria in the gut, which plays a central role in many aspects of health and disease.

Fiber also absorbs a good amount of water and expands in the stomach, helping keep you feeling fuller for longer.

3. May improve heart health

Thanks to their high content of antioxidants, fiber and heart-healthy fats, chia seeds have been shown to help prevent cardiovascular disease in several ways.

One of the most powerful effects is it ability to reduce inflammation and decrease several risk factors of heart disease, such as high cholesterol and blood pressure. Inflammation can put extra strain on blood vessels and is thought to contribute to heart disease along with a slew of other chronic conditions.

Chia is high in omega-3 fatty acids, boasting even more omega-3s per gram than salmon. Omega-3s work to protect the heart by lowering blood pressure, cholesterol levels and inflammation. Meanwhile, the fiber found in chia seeds can help manage cholesterol levels and keep the arteries clear to minimize the risk of coronary heart disease.

A 2021 study also found that chia can help reduce high blood pressure/hypertension. In this study, adults with hypertension experienced significantly reduced blood pressure levels compared to a control group when they consumed 40 grams per day of chia seeds (about 1.5 ounces) for 12 weeks.

4. Help balance blood sugar

Rich in both alpha-linolenic acid and fiber, evidence has suggested that chia can help maintain normal blood sugar levels and fight development of type 2 diabetes and insulin resistance.

Human studies even have found that adding these seeds to white bread reduces the glycemic response and can help prevent spikes and crashes in blood sugar levels.

5. Can boost energy and exercise performance

Chia is often used by athletes for carb loading, a strategy that helps maximize the storage of glycogen in the muscles and liver to optimize endurance and boost exercise performance.

In fact, a study published in the Journal of Strength and Conditioning concluded that consuming chia seeds enhanced exercise performance for workouts that lasted 90 minutes the same way a sugar-laden sports drink would but without all the unhealthy sugar. In the study, half of the athletes drank 100 percent Gatorade, while the others consumed half Gatorade and half chia drink.

In the end, the runners’ times were matched, but the chia group consumed far less sugar.

Plus, studies have shown the protein content of these seeds is among the highest of all seeds and grains, giving it the ability to help build muscle mass and increase strength. Research shows that consuming protein as a post-workout meal can aid in the repair of muscle tissues and can also build new muscle to speed up recovery time between workouts.

6. Help build stronger bones

Chia can help strengthen bone health and preserve bone density while reducing the risk of serious conditions like osteoporosis. This is because the seeds are loaded with calcium and manganese, two minerals that are needed to maintain bone health.

With about 99 percent of the calcium in your body stored in your bones, calcium serves an important role in maintaining bone strength and density. Manganese is also involved in bone metabolism, with studies showing that a deficiency in this key nutrient can impair bone resorption and decrease bone formation.

7. Aid in weight loss

Chia seeds rank among the top plant-based protein foods, which is why they are great to consume for those trying to put on lean muscle, burn fat, and manage hunger and appetite.

How can chia seeds help you lose weight? Studies have shown that increasing your intake of protein can help promote weight loss by curbing cravings and cutting caloric intake.

One study published in the American Journal of Clinical Nutrition, for example, showed that increasing protein intake by just 15 percent of daily calories led to significant decreases in energy intake and appetite. Other research has shown that chia may help reduce levels of ghrelin, the hormone responsible for stimulating hunger.

8. Fight cancer growth

Chia is rich in alpha-linolenic acid (ALA), a type of omega-3 fatty acid that gives it the potential to act as a cancer-fighting food.

One in-vitro study published in the Journal of Molecular Biochemistry found that ALA helped limit the growth of both breast and cervical cancer cells. Researchers also found that it caused cell death of the cancer cells without harming the normal healthy cells in the body.

While more research still needs to be done to find out the deeper implications of ALA on other types of cancer, this is a great discovery for women struggling with these increasingly common types of cancer.

9. Enhance oral health

Because chia is full of calcium, phosphorus, vitamin A and zinc, it helps promote dental and oral health.

Calcium is the building block of your teeth and necessary for maintaining oral health. Meanwhile, zinc prevents tartar by keeping plaque from mineralizing onto your teeth and has an antibacterial effect that keeps bad breath germs away.

Vitamin A and phosphorus are also important for strong teeth and a healthy mouth.

10. Combat inflammation and chronic disease

Chia seeds are rich in antioxidants and omega-3 fatty acids, which play a crucial role in reducing inflammation and protecting against chronic diseases.

Chia seeds contain powerful antioxidants like caffeic acid, chlorogenic acid, kaempferol and quercetin. These compounds help fight free radicals in the body, reducing oxidative stress and cell damage.

By combating free radicals, chia seeds may lower the risk of various health issues, including heart disease, cognitive decline and certain types of cancer, as mentioned above.

The omega-3 fatty acids in chia seeds, particularly ALA, have been associated with reducing inflammation in the body. Chronic inflammation is linked to numerous health conditions, and regular consumption of chia seeds may help alleviate inflammatory markers.

Studies have shown that chia seed components can help reduce blood pressure, platelet aggregation and cholesterol levels, all of which contribute to better cardiovascular health, for instance.

11. May help improve anxiety and depression symptoms

While research specifically on chia seeds and mental health is limited, there is evidence to suggest that the nutrients in chia seeds may contribute to improved mood and mental well-being.

The high omega-3 content in chia seeds may play a role in supporting brain health and potentially alleviating symptoms of anxiety and depression. Omega-3 fatty acids are known to help fight inflammation, which has been linked to both anxiety and depression.

Chia seeds are a good source of magnesium, a mineral that has been associated with reduced symptoms of depression and improved mood.

12. Support healthy pregnancy

Chia seeds offer several benefits for pregnant women due to their rich nutrient profile. What eating can chia seeds during pregnancy do?

Chia seeds are one of the best plant sources of ALA, a form of omega-3 fatty acid. During pregnancy, omega-3s are particularly important for fetal brain development and may reduce the risk of premature birth.

Chia seeds also provide essential nutrients crucial for pregnancy, including:

• Magnesium: Important for fetal development and may help prevent adverse pregnancy outcomes.
• Calcium: Supports fetal bone development.
• Iron: Helps prevent anemia during pregnancy.
• Folate: Essential for fetal neural tube development.

The fiber and protein content in chia seeds may help control blood glucose levels, potentially reducing the risk of gestational diabetes.

Chia seeds’ high fiber and protein content, along with their ability to absorb water, also can help pregnant women feel fuller for longer, which is especially beneficial during pregnancy when nausea and hormonal fluctuations can affect appetite.

How to use

How many chia seeds should you eat a day? Between one and three tablespoons per day is a typical amount that’s recommended.

Be sure to consume them with lots of water, which helps fiber do its job.
