As Americans eat less chocolate, Hershey’s begins pushing meat bars

American protein fiends who want a break from yogurt cups and Clif bars will soon have another option: meat bars.

Starting this summer, Hershey’s will introduce a souped up version of jerky from its Krave Pure Foods division, which the company acquired last year. If the concept is a bit bizarre, so are the flavors: black cherry barbecue, basil citrus and pineapple orange. Meat snacks are a tiny category in the US, said Marcel Nahm, the vice president of US snacks for Hershey’s. But as more consumers pore over food labels to find healthier, protein-packed snacks, more food companies are banking on health foods becoming a lasting trend.

The pivot is especially important for Hershey’s, which is losing American consumers (paywall) of its classic chocolate bars as they’ve moved onto other sweets and snacks.

今回取り上げる表現はsouped upです。upが付いているので、「改良した」などの意味を連想しました。

『ジーニアス英和辞典』（第五版、大修館）でsouped upを調べたところ、「〈車・エンジンなどが〉パワーアップした」と載っておりました。

またオンラインの辞書Academic Dictionaries and Encyclopediasには” to make something more powerful”と載っており、例として“ They had to soup up the air-conditioning to keep her computers from overheating in the summer.”と載っておりました。
主に車や機械などに使う形容詞のようですが、食べ物に使っていることに面白みを感じました。（Gomez）
