Changing lifestyles and new eating habits

Americans today have different eating habits than they had in the past. There is a wide selection of food available. They have a broader knowledge of nutrition, so they buy more fresh fruit and vegetables than ever before. At the same time, Americans purchase increasing quantities of sweets, snacks and sodas.

Statistics show that the way people live determines the way they eat. The United States Department of Agriculture (USD

A

and the food industry compile sales statistics and keep accurate records. For instance, red meat, which used to be the most popular choice for dinner, is no longer an American favorite. Instead, chicken, turkey, and fish have become more popular. Sales of these foods have greatly increased in recent years. This is probably a result of the awareness of the dangers of eating food that contains high levels of cholesterol, or animal fat.

It is more than likely that an unhealthy diet can damage people’s health.

According to a recent survey, Americans also change their eating patterns to meet the needs of different situations. For example, they choose pasta, fruit, and vegetables to give them strength for physical activity. Adults choose foods rich in fiber to prepare them for business appointments. For romantic dinners, however, they choose shrimp and lobster.

Americans’ awareness of nutrition, along with their changing tastes and needs, leads them to consume a wide variety of foods - foods for health, for fun, and simply for good taste.

When a man has children, the first thing he has to learn is that he is not the boss of the house. I am certainly not the boss of my house. There is no wisdom I can give new fathers more profound than what I have just said: you are not the boss of the house.

When one of the children comes to you and says, “ Dad, can I go explore the Upper Nile?” your answer must be “ Go and ask your mother”.

Only once did I make the great permission mistake.

One of the children came to me and said, “Dad, can I go out and play?”

“ Sure”, I replied. “I don’t see why not”.

That was the last time I couldn’t see why not. My wife came in and said, “Did you let that child go out?”

“ Yeah”, I said.

“Well, next time check with me. He’s being punished.”

From that day on I knew my place; and whenever a child starts to say, “ Dad, can I...” even though it is my name, I always reply, “

What did your mother say?”

And even if the child tells me that she got permission, I still say, “ Very fine. Just bring me a note from your mother. It doesn’t have to be notarized. A simple signature and date will do.”

Ironically, even though the father is not the boss of the house, the mother will try to use him as a threat: “ When your father comes home, he’s going to spank you. And this time I’m not going to stop him”.

According to the text, when a child asks for permission,
