For all the homies surviving on instant ramen: stuff like Spam, cheap gyoza/mandoo/shumai, and/or eggs can greatly help in making sure you get some cheap protein.
Unless you're literally starving to death, spam never has a positive impact on your diet. It's basically just salt, gelatin, and connective tissue scraped off the bone. Adding extreme quantities of salt to an item that already has extreme quantities of salt is awful nutritional advice, no matter how small the budget.
I'm poor and I sweat so much at my manual labour job that I get weak from the amount of electrolytes I have sweat out. Spam has the appropriate amount of salt for my poverty level.
Gatorade is so far above my price level. Salt added to water gets me through the day.
It is, but if that’s all you can afford to eat sometimes….
Also, dunno if they sell it on the mainland, but you can get less salty Spam so it’s less shit for your health. It’s also amazing in a musubi and can be pretty cheap since all you need is Spam, rice, and nori. Maybe add a little shoyu for flavor.
