Early game, food has its uses for building barracks and infantry if that is your choice. The downside of spamming barracks is the amount of goods that you have to use. In mid to late game, I only use food to build propaganda centers or help create a navy. If I'm land-locked or playing a map where a navy isn't that helpful, food becomes practically obsolete. Food is NOT used for ALL: tanks, planes, SP arty, TD, AC, SP AA, nukes, etc. Unless you are going for a low-tech, non-oil army, food just piles up.
Other uses of food = Militia. Even after the buff, this units is still a waste of research and resources and only hurt your K/D ratio. I have NEVER lost to an opponent that used militia, ever. I do use infantry early and occasionally Motorized Infantry (if i have tons of goods) BUT if I'm struggling with goods, infantry usually gets a pass. Every game that I win, I am swimming in FOOD which tells me I did right by ignoring it. I can't sell it, I can't trade it, heck I can't give it away.
Some advice to newer players...don't upgrade your food provinces. Spend your metal, goods, oil and rares on provinces that give just that...those four resources. Don't upgrade food provinces for the cash either...it is not that helpful.
