“I’d like to be at a healthier weight,” a friend told me. “But we just don’t have the money to buy expensive diet foods and there isn’t enough money to join a gym.” Many people feel that way — that a healthy diet and exercise plan is out of reach because of their high cost. Don’t lose hope! We’ll be looking at ways to make healthy choices without spending too much money.
First you don’t need to buy the expensive pre-prepared “diet foods.” Back in the early 1970s when I started housekeeping, 90% of the food I bought was ingredients. Very few things were preprocessed (预处理的). Now 90% of the food you find in the store is quick food. That’s a bad thing.
Quick foods like boxed “just add hamburger” meals have had the fiber (纤维) removed to make them faster to prepare. Take a look at the label (标签) on that box. It often has low numbers listed under “fiber” because fiber takes longer to digest. If the low fiber meal is digested, the result is that your body begins to store fat. Besides, your body is short of nutrients (营养物质). You will be driven to eat more to try to make up for the low quality of the food you are eating.
And then there are the chemicals the producers add to the quick meals to make them palatable. If not, the stuff would taste like cardboard and you wouldn’t enjoy it. However, these chemicals certainly aren’t good for your health.
What’s the answer? Buy whole ingredients and give up the expensive, low nutrition, processed foods. Do the cooking yourself and you will have control over what is in your food — and it will cost less, too.

Flu (which is short for influenza) is a highly infectious disease, the cause of which is a very tiny organism known as a virus. Several types of flu are recognized, depending on the type of virus that causes the disease.

Flu can often cause problems in breathing, and general infection of the lung. With elderly and weak people, these added complications often produce serious results. The virus, if not properly treated, can weaken the body so that patient may develop more serious illnesses, such as pneumonia and bronchitis. When people catch flu, they often complain of a headache or a sore throat. They usually have a fever and their temperature rises from the normal 37℃ (98.6) to about 39.5℃ (103). Sometimes a person has a dry hacking cough and aching joints.

Today many doctors use drugs that fight the disease. And scientists have also developed vaccines that help to prevent it. If the patient has proper treatment, and complete rest in bed, the virus is normally beaten within a week to ten days.

How does flu spread so quickly? When the infected person breathes out, sneezes or coughs, he gives out droplets of moisture in the breath from his mouth or nose. These remain in the air for some time. Flu viruses are present in these droplets. If a person sneezes in a crowd or poorly ventilated place, such as a lift, viruses can easily be carried from an infected person to a healthy person. This is known as droplet infection. The healthy person will breathe in the viruses given out by the infected person.

There are three main types of virus that cause flu, which are called type A, B and C. type A is the most powerful of the three, and undergoes minor changes in its genetic material every few years. The new form of the virus is called a strain. The new strain is not affected by the current vaccines. It is said to be “resistant” to them. So doctors must be continually producing new vaccines to combat the new strains of virus.
