Depends on where you are. I've always treated the 72 hour kit s a "Bug out bag", something you use to get away from the local area, Food storage to stay put (Always stay put unless you
must leave your house. Some recommend that you take the bare minimum you would need just to drink, and prepare food, under harsh circumstances. I can't remember how much that is, I think it is also heavily dependant on your fitness level, BMI and other factors.
Personally, we carry about 2 litres per person, and water purification stuff, but water is relatively easy to find locally,assuming what makes us need the 72 hour kit doesn't also taint the natural water supply. Things like floods that wash up sewage from the drains would taint local water supplies.
Here's a quote that came from someone who is more survivalist than realist

If your bag is too heavy, don't pack less,hike more

meaning, if your pack has all the essentials,and you still find it heavy, go on hikes with it, until it doesn't feel heavy anymore.
