问题     It should come as no surprise that the more stressed parents are at work, the greater the burden on their family. It’s also probably not a surprise that this【B1】______ can negatively affect a family’s nutrition. After all, the more time parents spend working, the less time and energy they have to plan and prepare healthful meals.
    Until recently, most studies have【B2】______the role of working mothers. Now, a study that looks at the family【B3】______, and at the role of fathers in particular, adds a new【B4】______ to the relationship between work stress and family nutrition.
    Moms’ work related stress is still a central factor in how well families eat because they typically do most of the food shopping and cooking. But dads’ work related stress has a large impact, too. The study found that when mom or dad【B5】______ high levels of work related stress, their families are eating one-and-a-half fewer family meals per week, and the parents themselves report eating fewer fruits and vegetables, more fast food.
    It’s worth noting that the study looked mainly at low income families who belonged to 【B6】______ or minority groups, so the findings don’t【B7】______ apply directly to other types of families. But the【B8】______ are wide ranging.
    When it comes to family nutrition, the researchers say, the entire family, not just moms, even kids【B9】______. Teaching kids, especially teenagers, to help with grocery shopping and to cook actual meals, instead of just popping a【B10】______ pizza in the microwave, could help families improve their eating habits.
