Can Eating Chia Seeds Have A Downside?

The tiny chia seed is a superfood which can help with weight loss, diabetes, and hypercholesteremia. Each serving gives you a healthy dose of fiber, protein, and omega-3 fatty acids. Unfortunately, it may bring on constipation, flatulence, diarrhea, and an allergic reaction. Chia seeds can also cause thinning of your blood. They could even be a choking hazard if you don't prep the seeds correctly.

Chia seeds, a superfood dating back to Aztec times, is now enjoying a rebirth of sorts. It features in every nutritional A-list as a rich source of fiber, omega-3 fats, protein, vitamins, and minerals. Granted, chia seeds are a great source of nutrition as part of a balanced diet. They are also constantly marketed as a weight-loss aid and scoffed down in large quantities by weight watchers. But you can have too much of a good thing, and this superfood is no exception. Here are some side effects you need to watch out for.

5 Downsides Of Chia Seeds

1. Tummy Troubles

Chia seeds are very high in fiber content – at nearly 11 gm per ounce serving, it takes care of a sizeable chunk of the American Dietetic Association’s recommended fiber intake of 38 g for men and 25 g for women for the day.1But a high-fiber diet doesn’t work for every body type. Too much fiber in one go can lead to flatulence, constipation, and diarrhea. It’s a good idea to eat chia seeds with a lot of water or soak them first. Soaking makes it easier to digest them. It also offers the added benefit of releasing all the nutrients stored inside.2

2. Blood Thinning Effect

Chia seeds can act as natural blood thinners, helping prevent your blood from clotting. If you are already taking blood-thinning medication like warfarin, steer clear of chia. For the same reasons, avoid chia seeds right after a surgery to avoid excessive bleeding.3

3. Allergy Alert

Chia seeds have a lot of protein in them and that’s bad news if you are allergic to the protein in chia. A 100 gm serving has about 16.54 gm of protein.4For those with a nut or seed allergy, chia seeds may be off the table. Get tested to check anyway. Reactions can range from skin rashes and hives to watery eyes, vomiting, and diarrhea. Also watch out for repetitive coughing, wheezing, difficulty swallowing, and a hoarse throat. You may also feel dizzy. As inflammation flares up in the larynx, tongue, and mouth, you could find it difficult to talk and even breathe. If your allergy is more severe, you may go into shock, your pulse may weaken, and your skin may turn pale or blue.5

4. Choking Hazard

Chia seeds have gained notoriety as a choking hazard. As one Time magazine report highlighted, incorrect consumption can lead to complications.6When you don’t pre-soak your chia seeds or eat them without roasting, you run the risk of gagging or choking on them. You may even end up in the ER as a result. Why? Because the seed when dry and unroasted absorbs as much as 27 times its dry weight in water. When this happens it turns gelatinous and expands hugely, plump with water. This sticky mass can get stuck in your esophagus, making you choke.7

5. Prostate Problems

The case for and against chia when it comes to prostate cancer isn’t closed just yet. While some research indicates it could decrease the risk of prostate tumor growth, other research contradicts this. For instance, one study indicated that consuming foods high in omega-3 fatty acids, like chia seeds, could trigger prostate tumorigenesis in men. This could imply an increased incidence of prostate cancer.8Previous research had a contradictory view. Researchers claimed that the omega-3 fatty acid alpha-linolenic acid did not increase prostate cancer risk and believed it even marginally decreased the risk.9The jury is still out on this one, but you may want to hold off on binging on chia.

How Much, How Often?

On the whole, the chia seed is a powerhouse of goodness. No wonder every nutritionist loves it. Ayurveda also recommends adding chia to your regular diet, conscious of its high fiber effects. But since the superfood is still not fully understood, additional studies will be needed before it can be declared safe for consumption by those with certain conditions like high triglycerides and low blood pressure, and even pregnant women.

Just ensure you don’t rely only on chia for your daily fiber intake. If you are aiming to lose weight, having more of it won’t lose you much. After all, you will have added on extra calories from the seeds as well. Typically, 1–1.5 tablespoon taken up to twice a day should be fine for most people. That’s the equivalent of a 20 gm serving that has 139 calories each time.10
