Half of Americans say it’s easier to do their taxes than it is to figure out how to eat healthfully – and 23% described their diets as extremely or very unhealthful, according to a new survey conducted by the International Food Council Foundation.   When it comes to decisions on food purchasing, taste is king says a new study.  87% of respondents say it’s the No. 1 factor in their decisions about buying food and beverages. Price (73%), healthfulness (61%) and convenience (53%) all ranked after price.  Not surprisingly, price was more important for consumers younger than 50, healthfulness for those who are older.  The survey, , also found that over half of the respondents say they are trying to lose weight; that’s more than said so last year but about the same as in the several years before that. But 23% of obese people and 44% of overweight people said they are not trying to lose weight.
