A shortage of popular food items is hitting restaurants and grocery shelves this summer, a sign that the world is still under pressure.

Many random foods have become hard to find over the past few months. They include lettuce in Australia, onions and salami in Japan, and even bottled beer in Germany.

The problem is usually not a lack of product, but a stretched global supply chain. There are many factors that affect it, from adverse weather to the Pandemic.

People's ability to buy things like soda and beer goes down when manufacturers can't make enough bottles and cans. Supply chain challenges are made worse by a shipping container shortage. Food and energy prices went up because of the invasion of Ukraine by Russia.

There is a new menu of inflation indicators.

There is a list of hard-to- find items. Due to a shortage of chili peppers, the maker of the famous sauce has stopped production. The end of days and the worst news of the year have caused consumers to rush to stock up.
