Wheat has gone up in price, last summer was a disaster for farming as it was so wet. There is then a knock on effect as it then affects the price of produce farmers use to feed their livestock etc, so milk goes up, then fresh meat....
If companies who produce goods have to pay more and ship in from elsewhere, then the cost is passed on to the consumer.
If you believe in global warming and its effects, then this situation is continually going to get worse and alter as adverse weather and conditions play their part on crops and livestock.
I've taken to making my own bread as it works out cheaper. I cook it along with some other stuff in the oven so its not just baking the one thing. Even for a total novice, something as simple as soda bread is easy to make, SR wholemeal flour, plain flour and buttermilk and 30 minutes in the oven. Sorted.
Also like lou, we buy a lot of fresh produce and make our own food over prepacked and processed. It does work out cheaper on the wallet, but it usually means I buy and cook lots of meals and freeze them. Not something everyone has time for each week.
I also grow some of my own veg, potatoes are easy to do in a pot in early summer and give a great crop. Same with other root veggies. Fun to do and kids can get involved also. Fresh out the ground carrots and spuds are yummy.
We also keep our own chickens as pets, also for eggs and meat so are saving money in that area also. Free range organic chicken and eggs at a reasonable cost to us.
We've raised pigs also for pork in the past. Best sausuages I've ever eaten were our own homemade ones. And the quality of the meat was wonderful.
