Currently, I keep drinking a kind of seeds - Basil Seeds.
Basil seed is like sesame but after absorbing enough water, it expands 30 times and like surrounded by white thing. It has lots of benefits. The biggest benefits are that basil seed can absorb the fat in blood and provide us omega3. It can also help you eat less as it would make you full. It is tasteless and the mouthfeel is special( I dont know how to describe..) so I always add it into different drinks like Ribena, apple vinegar and honey water, etc. You name it.
I dont know if you could find it in your town but I hope you could try it and become more healthier:)
