The soyamilk process is lengthy, but it is unbelievably economical! One cup of soy beans cost about 10 rupees. But you produce 3-4 liters of milk, that may be worth at least 100 rupees! The heart patients usually are wealthy people, so they won’t care. But the non-heart patients, the poor ones, should care for this cheaper and healthier product. The rice milk is also similarly very cheap to make. However, both the processes need at least one food grinder, which may not always be affordable initially to the poorer ones. However, in long run, the cost of grinder also is recoverable if the whole family turns to this milk.
