DH has been diagnosed with high blood pressure and high cholesterol. We generally eat okay, but he really wants to see an improvement on his next health analysis, so we have all been working on increasing our heart-healthy food intake. Unfortunately, DH is not the cook or grocery buyer in our family has almost no knowledge of nutrition or food content, which leads him to make odd and uninformed choices in re: to his meals. (One example, we went to our favorite BBQ place and he ended up ordering a grilled chicken sandwich. Later he sadly commented that there had been almost nothing for him to eat on the menu. Pulled white meat chicken, lean brisket, and fish were all on the menu too, but for some reason he equated "smoked" with "really awful for you." He's also been ordering caeser salads everywhere we go--and was shocked when I pointed out that caesar dressing is quite salty and fatty.)
Now someone told him that fruit is "full of fructose." Which, yes, I understand fruit has natural sugar, but he has become waaaaay overconcerned with it, basically equating an orange to a ball of white sugar wrapped in rind. He wouldn't eat a second triangle of watermelon the other day because of "all the fructose." :::eyetwitch::: It's a triangle of watermelon, dude. You're not eating a whole watermelon in a single sitting. And you were eating almost no fruit before. And he doesn't drink soda, so he's already a step ahead. It was a little brain-hurty to be arguing to someone that fruit is, in fact, not inherently "bad" for you.
