Food tab should also display total calories

Since foods have different calories/100g, then as well as measuring the total weight there should also be a helpful indicator as to what the total calories in the food inventory is. This would help better plan for certain days when you need to climb or do strenuous activities or just better measure how many calories used a day, per the player's playstyle.

I think it's a good thing that you have  to  do some work if you want to figure out exactly how many calories you have. Not to mention that  the UI is getting bogged down as it is.
