Read the passage carefully. Then answer the questions or complete the statements in no more than ten words:

Just Ask Grandma

We read and hear a lot about healthy eating in newspapers and on TV nowadays. Experts and nutritionists tell us what to eat, when to eat and how to eat to stay healthy, Some of the their advice seems reasonable. Some just sounds strange. Who can we rely on?

Well, ask yourself another question: How did people choose foods and stay healthy before there were nutrition experts? We relied on culture, which is another way of saying: on tradition and common sense.

All of us carry around rules of thumb about eating that have been passed down in our families or plucked（采集） from culture. Earlier this year, US writer Michael Pollen posted a request about these rules on The New York Times website. Within days, he received more than 2,500 responses. Not all of them have stood the test of time or been confirmed by science, but all of them have something to teach us, Pollen said.

Here are some of Pollen’s favorites:

My parents are both from Italy, and one of our family rules was that you could not leave the table until you had finished your fruit. It was a great way to put fruit into our diets and also helped satiate（满足）our sweet tooth, keeping us away from less healthful sweets. – Marta C. Larusso

Don’t eat anything that took more energy to ship than to grow. – Carrie Cizauskas

“It’s better to pay the grocer（食品商） than the doctor” was the saying that my Italian grandmother would frequently use to remind us of the love and attention to detail that went in to her cooking – John Forti

If you are not hungry enough to eat an apple, then you are not hungry. – Emma Fogt

“Make and take your own lunch to work.” My father has always done this, and so have I. It saves money and you know what you are eating. – Hope Donovan Rider
