How many donations worth of ten grains of rice does one need to live healthy for one day?

Good day!

I've been contemplating about https://play.freerice.com/ for a while. It lets you do menial tasks/train your mind with the function to donate for those in need at the same time.

Since I have no idea about the impact I've been working on, I decided to come here and ask about your insights. How much worth of those donations does one need in order to, say, eat healthily for one day? Live healthily for one day? Have their basic needs fulfilled for one day?

Thank you!

It's hard to get a good number there. Most nutritional measures are by volume or mass, rather than grain count, and the number of grains in a cup or kilo is variable based on type, (un)processed, etc. One site I found says 7k~10k per cup, which would be ~37k/kg. Nutritional calculations are complicated by the conversion from uncooked to cooked because rice usually expands as you cook it, so 1 cup uncooked is fewer grains than uncooked, but nutritional data is usually for cooked foods. Looks like maybe cooking expands the rice by about 3x. Then there are questions regarding what the necessary amount would be. A cup of cooked is ~200 calories. A standard estimate for number of calories needed, ignoring nutrition, is 2k. Rough guess?
10c cooked rice = 3.33c uncooked = 23k
33k grains
