I'm almost certain what you have are lotus seeds. https://en.m.wikipedia.org/wiki/Lotus_seed
They're usually a pale ivory colour and as they age, deepen to a more light golden-tan. Since colours can be deceptive viewed over the internet, I can't say how fresh the ones you have are.
Packaged like yours, perhaps they were meant to be planted unless they've been repackaged by someone. There appears to be much more than is needed to start new plants so I'd hazard a guess these were meant for food. In fact, I have an unopened package of lotus seeds in my pantry as I cook a lot of Asian foods.
Lotus seeds are commonly used in Asian cooking. They're used to make lotus seed paste (quite yummy) as a filling in festive moon cakes. They're also added to soups. Lotus seeds are considered a 'yin' food noted for their cooling effect and clearing 'excess heat' in traditional Chinese medicine.
Some photos of lotus seeds. The first one is from Wikipedia. Please let me know if your seeds match the photos.
