It's likely he doesn't have a car, most New Yorkers don't. I'd also recommend switching to a fruits and vegetables diet, instead of ramen. There are enough dedicated fruit stores in New York that make fruits and vegetables cheaper and healthier than ramen. In New York, an example of this kind of store would be "Three Guys From Brooklyn", or "Circus Fruits". With these sorts of stores you can easily bring your food expenses below $60 a month while maintaining a healthy diet.
You have to know where to go, what to buy, and what to cook.
I've been a vegan for a number of years now and I could live off $60/mo if I wanted to. The main point is convenience. If you don't want the effort of preparing food then it costs a lot more. Simple staples like lentals, rice, etc supplemented with vegetables is a crazy cheap way to eat.
In SF districts like the mission it's easy to get cheap fresh fruit and vegetables. A lot of it is supply and demand. If you shop at Safeway they have an expectation about your spending and price accordingly.
If you are trying save every penny shop where other people who have no money shop. That probably means neighborhoods you might avoid otherwise.
It's not a typo. In the post I mentioned Three Guys From brooklyn, here's a link to their weekly circular. http://3guysfrombrooklyn.tripod.com/id4.html, note that the price listed for fruit and vegetables in that circular are about the average prices for all their fruits and vegetables. Certainly things like packaged foods will be a little higher, but if you purchase mostly fruits, vegetables, tubas (the average price of a bag of 5lbs potatoes there is $1.99), etc, in addition to a few packaged foods such as orange juice, you can easily eat for less than $60 a month.
I'd recommend sticking with ramen. There's zero chance that fruit is cheaper anywhere on a cost per calorie basis, ramen is easier to find everywhere, ramen is pretty tasty and you can take more calories of ramen before you want to throw up, you can take more calories of ramen before you have diarrhea, ramen stores compactly and easily, ramen doesn't go bad, and the health benefits of fruit and vegetables are greatly exaggerated ( partly by some folks whose interest in promoting them has nothing to do with their purported health benefits). I, for one, never get sick, work out all the time, am slim and stronger than 99% of the population, have good blood pressure and cholesterol, and, to cut costs, a significant portion of my diet is ramen.
I was merely pointing out that if you have limited funds and running a startup, ramen and exercise is not a bad trade-off considering the costs of fruits/veggies are usually higher.
Standard Ramen pretty much has no nutritional value. Add some veggies (first boil finely chopped carrots & celery, add frozen corn, broccoli, peas) then put in the ramen mix.
I for one think MSG is a good thing but for someone so concerned with it, I'm surprised you're recommending broccoli. Other than cheese, soy and tomato, broccoli is about as high in glutamate as a food gets.
