misleading 誤解を招きやすい
the bottom line is .... 肝心なのは～ということだ
Smoothies enjoy a “health halo” that can be misleading, “but the bottom line is quantity, and people are often consuming a 20- or 24-fluid-ounce smoothie. That’s a lot.”
Even if you’re making your smoothie at home, using only fruits and vegetables with no other added ingredients, you can drink it in just a few minutes, compared with the 15 or 20 minutes it would take （wouldが出てきたらたいてい仮定法）to eat the same fruits or vegetables whole（wholeはそのままって意味）, Ms. Krieger said. And if you’re drinking smoothies frequently, you may be consuming a lot more fruit than you would otherwise（you would be consuming fruits as a wholeってことです。やっぱり仮定法）.
