An army of nutrition experts is constantly reminding us that most fast food is bad for health. But they’re not around to back you up when your children or grandchildren unleash powerful weapons of cuteness to convince you to stop at a fast-food chain. It’s hard not to give in when the ones you adore put on the pressure, even when they’re older.

Case in point: my son, who is majoring in economics in college, recently informed us that he could reduce his expenses at school by 32% if he could eat at fast food restaurants daily and ditch the dorm meal plan. While I was impressed by his math skills and economic reasoning, I warned him that fast food often could lead not only to weight gain but also to other medical problems. Then I resorted to my own weapons: the latest research. Knowledge is power, after all, and two new studies gave me the confidence to hold my ground. They may work for you, too.

The latest findings

One study, published online in the journal Thorax, looked at possible connections between consuming different types of food and the development of asthma, rhinitis (chronic stuffy nose) and eczema, a skin condition. The researchers surveyed 500,000 kids from 31 countries in two age groups: ages 6 to 7 and ages 13 to 14. In both groups, kids who ate fast food three times a week or more had increased risks of asthma, rhinitis, and eczema—as much as a 39% increase in severe asthma risk for teens and 27% for younger kids. And wouldn’t you know—just three or more servings of good old fruit appeared to reduce the severity of symptoms for all three conditions.

Another study, published in this month’s Archives of Pediatrics and Adolescent Medicine, found that teenagers and kids consumed far more calories in fast-food and other restaurants than they did at home. The numbers were alarming: eating out was associated with taking in as many as 160 extra calories daily for younger kids and as many as 310 calories daily for teens. That information is troubling because obesity is a serious problem for children in the U.S. and around the world.

Potential weight gain is just one consequence of eating out often. Fast and restaurant foods are often heavy on fat and sugar, both of which can lead to the development of chronic disease when consumed in large quantities.

Fighting back

So what’s a parent or grandparent to do? I turned for advice to Stacey Nelson, a registered dietitian who is a clinical nutrition manager at Harvard-affiliated Massachusetts General Hospital. She says it’s not realistic to ban children from eating out, but to be careful when you choose to do so. “Fast food is not health food and never will be, so the idea is never to make it a habit. But when it seems like that’s all that is available, there are always ways to make the best of a less than ideal situation,” she told me.

Here are some of Nelson’s top tips:

  • Don’t let kids drink their calories. Order water or fat-free milk instead of a soda, juice, milkshake, frappe, or smoothie.
  • Watch the side dishes. Get a side salad or baked potato if possible instead of French fries and onion rings, which can be laden with saturated fat.
  • Don’t super-size. Instead, order smaller portions, such as items on the snack menu.
  • Choose grilled foods instead of fried foods.
  • Hold the cheese. This eliminates extra calories and fat.
  • Use mustard and ketchup instead of the “special sauce.”
  • Model good eating behaviors. That means following all of the rules yourself.

Good choices

Most fast-food and other restaurants offer many dining options, some of which are better than others. For example:

  • A Burger King Double Whopper has 830 calories and 50 grams of fat (17 grams of saturated fat, nearly the daily limit) while a hamburger has only 240 calories and 9g of fat (3.5 grams saturated).
  • An Angus Bacon and Cheeseburger at McDonalds has 790 calories and 39 grams of fat (18 grams saturated) while the Chipotle BBQ Snack Wrap has 250 calories and 8 grams of fat (3.5 grams saturated).
  • A Wendy’s medium fries delivers 420 calories with 21 grams of fat (14 grams saturated), while a garden salad is 210 calories and 13 grams of fat (only 2 grams saturated).

In other words, look at the nutrition information that many restaurants make available these days and make choices with fewer calories and less saturated fat and sugar.

Kids won’t necessarily cotton to these rules. Choosing—or avoiding—fast food will be a matter of negotiation. But what part of parenting and grandparenting isn’t? We negotiate bedtimes and homework and playtime. Food choices shouldn’t be any different.

I employed this tactic myself when I spoke with my son about eating fast food daily. I told him about the risks of these foods, then laid down the law: Stick to the college meal plan and indulge in fast food only once in a while, using his own allowance. I was happy to hear him agree enthusiastically. It was a little surprising, actually—until I heard his next economic discovery. He said that if he didn’t spend his allowance eating out, he’d be able to save up for a fabulous spring-break trip to Mexico. I’ll let you know when I’ve figured out how to negotiate that deal!

      I believe that kids should be allowed to have fast food because if they don’t then they might get some other sweets but that will kill them too

  13. Richard

    I agree. This seems like a helpful tool for any parent whose kids are being bombarded with fast food options that are fast and easy. We should take the time to teach them lessons of nutrition and be a good example by not taking the easy route with fast food!
