Science has proved that during an eclipse, there is enhanced radiation of ultraviolet and other rays that contaminate food. Obviously, the consumption of such food will be harmful for us. Although there may not be any immediate reaction, in due course of time, our teeth or digestive system are affected. Cooked food is affected as it contains water, and during an eclipse, water attracts more radiations, which in turn contaminate the food. To prevent this, tulsi (basil) leaves are placed on cooked food to repel radiations.
Hey! On which evidence do you support your claims? Do you have any links to share?
To mention a few

I have to say I was looking for scientific evidence. I have nothing against Ayurvedic medicine in principle, but it requires belief in a whole metaphysical system and the links you provided offered no evidence that the assertions made were tested in any way.
