I watched this video https://nz.news.yahoo.com/video/watch/22047118/food-prices-expected-to-increase-in-america/ It is interesting that you in a family of 2-3 children - save on some products? For you some products are expensive? For example here in N.Z. I know, many usual families where 2-3 children, buy only what is necessary, but not always what they want.
Meat prices have gone up drastically because of shortages of feed last year making farmers produce smaller flocks. Additionally, the swine viruses have caused production problems, and an avian virus was just spotted in one California poultry flock. The colder winter will affect produce as well, although the dock strike in California seems to have resulted in a spate of less expensive citrus fruits for awhile. Large (pound) bags of walnuts now cost almost $13 at a local club warehouse, which is about $5 more than they were about ten years ago. Catfood that cost about $8 ten years ago now is about $22. Eggs are still a good buy, although if you want the high omega kind they are almost $3 a dozen. A head of lettuce varies from $1.19 to almost $2 a head. Cauliflower is about $3 a head, cabbage a bit less. Tomatoes will be expensive now until high summer. Bread varies from about $2 to $6 a loaf depending on how fancy you want it. Many are now doing much of their shopping at economy grocery stores such as Aldi's, or club warehouses, such as Sam's or Costco, which offer lower prices but less choice. Those near enough to farm stores can also save money shopping there in season. People with small budgets and an addiction to out-of-season fruits and vegetables are doomed.
In N.Z any agricultural products there is a lot of, only everything goes for export What kiwi say... Here in nz we export so much of own food that us kiwis get the expensive left overs. Own food is cheaper to buy in every other country we supply, we pay the highest price some comment from forum...
One of our grocery stores sells many vegetables from South America. After becoming sick from some of their salad greens I seldom shop there any more.
If there is significant drought on a worldwide level, many things we are used to having at a good price here in the US will probably get expensive. Most staples, like flour, sugar, and cooking oil, are still fairly reasonable here. Cheese prices are OK compared to meat but used to be lower. Milk prices ditto. NZ has been mentioned lately as a nice place to retire to, which probably isn't helping the food supply situation. Additionally, I have noticed that producing nations tend to keep the best produce for themselves. Why ship it long distances if it might spoil? My spouse actually grows a small vegetable garden in the summer to lessen our food bills a bit. We used to get wonderful tomatoes until the tomato blight came a few years ago. We still get many peppers and loose leaf lettuce, and zucchini and green beans until the bugs get them. We don't like to use poisons. Our peas usually don't do well because it warms up too soon after we are able to plant them. Green onions do well, and if we plant broccoli and spinach when it is cool enough we get good quantities of those. Swiss chard is ultra reliable, but who wants massive quantities of Swiss chard? I have found it's not bad with cheese, though.
