News that will give chocolate lovers pause: Not only is demand up for chocolate (thanks to seemingly endless reports of its health benefits) but supply is down, thanks to a shortage of cocoa beans in West Africa (the source for the majority of the world's beans). The result? Chocolate prices have soared to $12.25 per kilo (that's about 2 1/4 pounds) -- up 45 percent from 2007, says The Wall Street Journal. Cocoa butter prices are rising, too (that's what gives chocolate its melt-in-your-mouth texture), which means it's costing manufacturers more to make their product. A slightly more expensive bar may still be worth it, though (here's a scientific reason why you should indulge, even -- or especially -- when you're stressed out).
Wild-caught fish could be on its way to becoming a special treat: The global fish-price index of the UN's Food and Agricultural Organization (FAO) hit a record high earlier this year, a result of increased demand and a surge in oil prices (which has a big impact on the cost of operating fishing boats and transporting the catch). Fish that is wild (not farmed) has seen the sharpest price hike, nearly doubling between 1990 and 2012, whereas the index for farmed fish rose by only a fifth (here's why). Some of the best eco- (and wallet-) friendly options are farm-raised striped bass or farm-raised rainbow trout, which sell for about $8 a pound and have relatively light impact on the environment. That's significantly lower than wild-caught fish that offer a similar taste and texture, such as cod (which ranges from $14 to $25 a pound) or halibut ($24 a pound).
Price Down: Honeycrisp Apples
The "designer" apple known as honeycrisp is sweet, juicy, snappy -- and (historically, anyway) pricey, costing as much as $4.50 a pound while in-season Cortlands went for $1.50 a pound. Whether because of the catchy name or the truly sweet taste, demand has jumped in recent years, and, until recently, supply couldn't keep up, since apple trees take five or so years to begin producing fruit in enough quantities to sell commercially. (This fascinating article explains more.) Finally, though, all those honeycrisp trees are meeting demand, and the USDA's National Fruit and Vegetable Retail report says the variety is actually now going for 14 percent less per pound than it was last year.
