People today are becoming increasingly aware that a proper diet is the foundation of good health. If we don’t have a regular diet of proper food, we don’t have the fuel to perform at our best. However, some people think not eating breakfast doesn’t matter a lot, though eating it is important. Get the truth behind this common misconception and other meal frequency and timing meals.

Will eating breakfast every day help me lose weight?

Yes, eating the morning meal can actually help you shed pounds. People who have breakfast are less likely to eat diet-busting(破壞的) junk food and are more likely to exercise later in the day, as studies show. People who skip breakfast, on the other hand, usually make up the calories — and then some — before day's end. Researchers found that 78 percent of the men and women included in the National Weight Control Registry — who have maintained an average weight loss of 66 pounds for more than 5 years — eat breakfast every day.

Is "grazing" really healthier than eating three square meals a day?

No. Eating many small meals throughout the day is probably not better for you than three main meals, the traditional amounts of food for breakfast, lunch, and dinner. The idea that "grazing" is healthier comes from a few old studies showing that eating frequent meals throughout the day may burn more fat and lower insulin （胰島素）levels. But later studies have found no benefit to grazing. It's not healthier than eating three squares, according to the American Dietetic Association.

I've always eaten most of my calories at dinner. If I'm healthy, is there any reason for us not to keep doing this?

Hard to say. Instinctively, it sounds like a bad idea. Yet "one-mealers" tend to eat less food totally, scientists say, so your dining habit may actually help you stay tidy and attractive. On the other hand, one small, brief study by USDA scientists found that eating just one daily meal may cause small increases in blood pressure, blood sugar, and cholesterol(膽固醇). If your annual blood tests show a rise in any key risk factors for heart disease or diabetes, it is high time for you to reconsider your meal strategy.

Will bedtime snacks make you fat?

No. But that's not permission for you to eat cookies before going to bed every night. Consuming more calories than you burn through physical activity produces big loose stomachs and weak legs no matter what time you overeat. A habit of snacking in front of the television every evening will lead to weight gain, but no more so than having a six-egg pancake for breakfast or conquering a bag of beans with sweet food at your desk every afternoon.

The final word

Eat fewer calories than you need in a day and you will lose weight. Eat breakfast because it will help you control calories better, not because it's a magic meal. Eat the number of meals that keeps you satisfied and energized. No one plan is best for everyone.

注意：每空格1個單詞。
For years, the automobile industry has been testing vehicles that use hydrogen as fuel. Now, people across the United States have had a chance to see and even drive cars that get power from hydrogen fuel cells (燃料電池).
But the hydrogen fuel cell is not a new idea. The fuel cell was first invented by Sir William Grove of Britain in 1839. Since then, many different designs, have been invented. There is one place where fuel cells are a proven technology: in space. The American space agency used fuel cells in its Apollo spaceships in the twentieth century.
The most useful fuel cell for transportation purposes is the Polymer Electrolyte Membrane, or P.E.M. fuel cell. It is simple and can operate at temperatures of sixty to eighty degrees Celsius. That is much lower than other fuel cell designs. A P.E.M. fuel cell has two sides divided by a thin membrane (膜). Hydrogen gas is forced through one side where it comes in contact with a reactive material containing the metal platinum(鉑). The membrane separates the electrons(電子) from the protons(質(zhì)子) in the hydrogen atoms. The protons pass through it to the other side of the fuel cell. But the electrons are captured to do work; like powering a motor. Oxygen from the air is forced into the other side of the fuel cell. There, the gas meets the protons that have passed through the membrane. They combine to form water and heat. A single fuel cell does not produce a lot of electricity. But when many fuel cells are combined, they can produce enough electricity to power a vehicle. The product of the chemical reaction that powers fuel cells is water. This makes fuel cells a very clean technology.
Hydrogen fuel cell cars have been slow to develop because of many technical problems that have to be solved. For example, it is unclear how long the membranes in P.E.M. fuel cells will last. Also, fuel cells need water for their chemical reactions. They must be designed to start easily at low temperatures and in dry climates. And smaller, less costly fuel cells must be designed before they can truly take the place of gasoline engines. Now more models of fuel cell vehicles are being tested than ever before. The threat of climate change and the high cost of oil have increased interest in these vehicles that do not cause pollution.
