One of their coolest features is their versatility—you can sprinkle them on just about anything, from smoothies and salads to non-dairy yogurt and baked goods. When mixed with liquid, chia seeds transform into a gel-like texture, showing off its soluble fiber qualities. 

So, whether you’re looking to boost your meals or enjoy a little extra crunch, chia seeds are a delicious and nutritious choice!

Calories in 1 Tablespoon of Chia Seeds 

While chia seeds are healthy, how many calories are in one tablespoon of chia seeds? One tablespoon of chia seeds has roughly 60 calories, which isn’t too shabby considering all the nutrients they provide.

How to store chia seeds? 

Proper storage is key to keeping your chia seeds fresh. Start by placing them in an airtight container and stashing them in a cool, dry spot—think pantry or cupboard—away from sunlight and moisture.

Popping them in the fridge or even the freezer can extend their shelf life if you like to buy in bulk or don’t go through them at a slower rate.

Do chia seeds expire?

Surprisingly, chia seeds have a long shelf life. When stored properly, they typically last several years. Most packaging includes a “best by” date, indicating when the store needs to sell them for optimal freshness. 

While this date is a good guide, chia seeds can still be used after it, as long as they’ve been stored in a cool, dry place and remain free of any off smells or flavors.

How to tell if chia seeds have gone bad?

Can chia seeds go bad? Yes, and knowing how to spot spoiled chia seeds can save you from an unpleasant surprise. One way to tell if your seeds have gone bad is by checking the smell—fresh chia seeds have a mild, nutty aroma. If they start to smell rancid or off, it’s a red flag. 

Next, give them a visual inspection. Look out for any mold or changes in color. Mold thrives in moist environments and can quickly take over. 

Finally, taste a small amount if you’re unsure. Fresh chia seeds should have a neutral, slightly nutty flavor; if they taste bitter or sour, it’s best to toss them. Trusting your senses can help you avoid unwelcome surprises or sickness. 

How long do chia seeds last?

Chia seeds can last quite a while—usually between 2 to 5 years. This impressive shelf life means you can enjoy their nutritional benefits for an extended period. If you want to make them last even longer, refrigerating or freezing them can help preserve their freshness beyond the typical timeframe.

What happens when you eat expired chia seeds?

Eating expired chia seeds is usually not a big risk, but if they’ve truly gone bad, they can lead to digestive issues like vomiting or diarrhea. While food poisoning from chia seeds is rare, spoiled seeds might cause some discomfort. 

If you do experience symptoms, stay hydrated and consult a healthcare professional. 

What to do with expired chia seeds?

If you find that your chia seeds have gone bad, it’s best to toss them out. However, if you’re not ready to part with them, consider repurposing them for non-food uses. They can be great in DIY crafts, like making homemade exfoliating scrubs or natural decorations. Properly disposing of or creatively reusing bad chia seeds can help you avoid waste and keep your pantry clean.
