They are also known for their anti-inflammatory and anti-cancer properties, making them appealing for promoting skin and hair health.

Are chia seeds safe to eat?

While chia seeds offer numerous benefits, some individuals must approach their consumption with caution. Let’s explore the types of people who should be careful about incorporating chia seeds into their diet and the reasons why.

1. Individuals with digestive issues

• High-fibre content: Chia seeds are rich in fibre, which is generally beneficial for digestive health according to Harvard Health. However, this high fibre content can pose a problem for individuals with pre-existing digestive issues, such as irritable bowel syndrome (IBS) or other gastrointestinal disorders.
• Possible consequences: For these individuals, consuming large amounts of chia seeds can lead to digestive discomfort, including cramps, stomach pain, diarrhoea and bloating
• Recommendation: “If you have a history of digestive issues, it’s best to consume chia seeds in moderation and to soak them beforehand, as this can aid in digestion”, says nutritionist Avni Kaul.

2. People with diabetes and those on blood sugar medications

• Benefits and risks: Chia seeds are often touted for their benefits in managing diabetes due to their ability to stabilise blood sugar levels. Their high fibre content slows down the absorption of sugar in the bloodstream. However, excessive consumption can result in dangerously low blood sugar levels for some individuals.
• Concerns for people with diabetes: While moderate quantities can be beneficial, excessive intake may lead to sudden drops in blood sugar, which can potentially result in hypoglycemia.
• Recommendation: According to the nutritionist, “if you have diabetes or are on medications that affect blood sugar, it is important to monitor your chia seed intake and consult a healthcare provider for tailored guidance.”

3. Individuals on blood pressure medications

• Omega-3 fatty acids: Chia seeds are a significant source of omega-3 fatty acids, which have natural blood-thinning properties. While this is beneficial for overall heart health, it can be concerning for those already on medication to manage high blood pressure.
• Potential consequences: Excessive consumption may lead to a significant decrease in blood pressure, putting individuals at risk for dizziness and fainting.
• Recommendation: “If you are taking blood pressure medications, consult a healthcare professional before adding chia seeds to your diet, and monitor your blood pressure regularly”, explains Kaul.

4. People prone to allergies

• Allergic reactions: While chia seeds are generally considered safe, some individuals may experience allergic reactions to them. Symptoms can vary from mild to severe and may include skin irritation, redness, rashes, nausea, and vomiting.
• Recommendations for first-time users: Nutritionist Avni Kaul mentions, “If you are trying chia seeds for the first time, start with a small amount and watch for any adverse reactions.” If you notice discomfort, it’s advisable to discontinue their use and consult a doctor.

What is the right way to consume chia seeds?

For those who do not fall into these categories but still want to enjoy the benefits of chia seeds, here are some general guidelines to keep in mind:

1. Moderation is key: Limit your intake to a small serving size (about 1-2 tablespoons) to avoid adverse effects.
2. Soak before consumption: Soaking chia seeds helps them expand, making them easier to digest and reducing the risk of gastrointestinal discomfort.
3. Stay hydrated: Chia seeds can absorb a significant amount of water, so be sure to drink plenty of fluids throughout the day to stay hydrated.
4. Consult a healthcare provider: If you have any underlying health conditions or are pregnant or breastfeeding, it’s always a good idea to talk to a healthcare provider about the best dietary choices for you, as per the NIH Office of Dietary Supplements.
