Should we be drinking chia water? A dietitian explains the benefits, risks and myths

Chia water is one of TikTok's biggest wellness trends right now, with influencers making hefty claims about its health benefits. Some say it helps with weight loss while others praise it for improving digestion.

But while chia seeds are packed with fibre and other nutrients, experts say many of these claims have no scientific backing. Not only that, but consuming these seeds n the wrong way could even pose a choking risk in some cases.

We asked a registered dietitian what chia seeds can actually do for your health – and whether we should give the viral chia drink a go.

Dry chia seeds soak up liquid and expand quickly – they can absorb many times their own weight in water.

This means swallowing dry chia seeds and chasing them with water could create a choking hazard for some people, so experts advise against it.

Bini Suresh is a registered dietitian, spokesperson for the British Dietetic Association (BDA) and lead for nutrition and dietetics at Cleveland Clinic London. She points out that while chia seeds are nutrient dense, "it's important to distinguish nutritional value from proven clinical effects."

Essentially, chia seeds can be a useful addition to a healthy diet to boost nutritional value – but they're certainly not a miracle food.

Myth: Chia water melts fat

What the evidence says: No findings of any studies support this

Myth: Chia seeds are a complete weight-loss solution

What the evidence says: They may help you feel full but don't they cause weight loss on their own

Myth: More chia means more benefits

What the evidence says: Too much can cause bloating and digestive discomfort

They're nutrient-dense and come packing fibre, plant protein, essential omega-3 fats and minerals including calcium, magnesium and phosphorus.

"Chia seeds contain gel-forming soluble fibre, which can support regular bowel movements, contribute to a healthy gut and help meals feel more satisfying," says Suresh.

There's about 5g of fibre, external (that's a sixth of an adult's recommended intake) in one tablespoon of these seeds, and around 1.6g protein.

On social media, you'll see many claims about the health benefits of chia seeds.

They're most commonly linked to improvements in heart health, external, digestion, external, blood sugar control and weight loss, external.

But does the evidence stack up?

"Recent systematic reviews suggest chia supplementation may give modest improvements in measures like waist circumference, blood pressure or inflammatory markers in some populations," says Suresh.

"But it has not consistently improved cholesterol, blood glucose or other cardiometabolic outcomes."

More studies are needed, but it's already clear chia seeds are far from a magic bullet.

"Chia should be viewed as one useful ingredient within an overall healthy dietary pattern, rather than as a treatment for high cholesterol, diabetes or weight loss."

Anyone who doesn't usually eat much fibre should start with a smaller amount, (a teaspoon) and build up gradually (to one or two tablespoons) to reduce the risk of bloating or digestive discomfort.

"There is no requirement to eat chia seeds every day," notes Suresh. "Variety is important, so they can be alternated with other seeds, nuts, pulses and wholegrains."

Chia water is made by adding chia seeds to a glass of water, and waiting for the seeds to expand and turn the water into a gel-like liquid before drinking it.

It's generally safe if the seeds have been fully hydrated before drinking, says Suresh.

However, she adds, it isn't a detox drink, doesn't 'melt fat' and there is no evidence it offers greater health benefits than eating the seeds as part of a meal.

Suresh points out several practical drawbacks, including the fact that a glass of seeds and water can be unpleasantly thick and could cause bloating if a large amount is drunk quickly.

As it's filling, there's also the chance that it could end up taking the place of a more nutritionally complete breakfast or snack.

"Chia seeds are generally more enjoyable and useful when they're included in food," says Suresh

Combining them with oats, fruit and nuts, rather than relying on chia alone, bolsters nutritional value as well as flavour and enjoyment.

Good options include:

"While chia seeds do not generally need to be ground before eating, they should be eaten with adequate fluid or as part of a moist food."

Chia seeds are safe for most people – so long as they're not consumed to excess. There is emerging evidence that a minority of people have an allergy to them, but it's rare.

However, if you want to start including them in your diet, here are some things to consider:

"People with significant gastrointestinal disease, a history of bowel obstruction or swallowing difficulties should get personalised advice," says Suresh.

Chia seeds are full of useful nutrients and are a great way to crank up the nutritional value of some meals.

But there's no evidence that they have any detoxing powers or will result in weight loss on their own. They're no cure-all.

If you want to make the most of their nutritional value, add them to porridge, smoothies and yoghurt as opposed to a glass of water.
