Non-vegetarian food, including fish, is very bad for health. The dangers associated with infection of all kinds, are very real, and are very clearly documented.
Switching to vegetarianism is the best option. If we can grow more kitchen gardens with organic manure and completely do away with urea, we will be very healthy. In many places, we can get red soil. If we mix that with ordinary soil, the growth of vegetables is very good. For example, tomato. If we can produce more on our terraces, the prices in the open market will come down automatically when demand comes down and the supply is the same. Since the retail guy has to necessarily go for volumes, and this will bring down prices very quickly.
