Scientists have discovered thirteen kinds of vitamins. They say vitamins help to carry out chemical changes within cells. If we do not get enough of the vitamins we need in our food, we are at risk of developing a number of diseases. Which foods should be eaten to keep us healthy? Let us look at some important vitamins.

Vitamin A helps prevent skin and other tissues from becoming dry. People who do not get enough vitamin A cannot see well in darkness. Vitamin A is found in fish liver oil and the yellow part of eggs.

Vitamin B-1 is also called thiamine. Thiamine changes starchy（含淀粉的）foods into energy. Thiamine is found not just in whole grains like brown rice, but also in beans and peas, nuts, and meat and fish.

Vitamin B-12 is needed so folic acid can do its work. Together, they help produce red blood cells. Folic acid has been shown to prevent physical problems in babies when taken by their mothers during pregnancy. Vitamin B-12 is found naturally in foods like eggs, meat, fish and milk products. Vitamin B-12 is found in green leafy vegetables and other foods, like legumes and citrus fruits （柑橘类水果).

Vitamin C is needed for strong bones and teeth. The body stores little vitamin C. So we must get it every day in foods such as citrus fruits, tomatoes and uncooked cabbage.

Vitamin D prevents the children’s bone disease rickets （佝偻病）. Ultraviolet light from the sun changes a substance in the skin into vitamin D. Fish liver oil also contains vitamin D.

Vitamin K is needed for healthy blood. It thickens the blood around a cut to stop bleeding. It can also be found in pork products, liver and in vegetables like cabbage, kale and spinach （菠菜）.

Vitamins are important to our health. A lack of required vitamins can lead to health problems.

According to statistics published by the University of Scranton, about 45 percent of Americans usually make New Year’s resolutions—and the most popular resolution is losing weight. Of those who make resolutions, a mere 8 percent achieve them.

___1.__ Are we just setting ourselves up for failure? Learn how to make realistic resolutions and how to overcome the roadblocks along the way.

Setting a resolution to lose pounds isn’t a goal that’s achievable now. It may be a good long-term goal. ___2.__ Registered dietitian Elisa Zied says “… to be real when you make a resolution. It’s okay to shoot for the stars like making a resolution, but why not set a smaller goal and train smart?”

The same concept applies to weight loss. __3.___ These goals should help develop healthy habits that will finally help achieve your long-term resolution.

Notice that these goals are simple and achievable. “Instead of going from zero to 60, from never going to the gym to going four to five times a week, why not start with three days a week, get consistent and build from there,” Zied says. Set yourself up for success and map out your course by making appointments with yourself to be active. __4.___

You also need to be aware of your current exercise and eating habits to make achievable goals. Keeping a diary of your food and exercise habits can help. Record everything you eat and drink for three to five days and review it. __5.___For example, if you notice a tendency to snack on unhealthy fare, set a goal to eat a fruit or vegetable with each snack. Building on these smaller goals over time can help you achieve your long-term goal.

A. So why do so many of us fail to achieve our goals?

B. Once you notice your not-so-good habits, start fixing them.

C. Set between one and three weekly goals that you want to achieve.

D. Resolutions usually involve a commitment to sticking to your goals.

E. However, in order to reach it, you need to take baby steps to get it down.

F. If you treat your goals like set appointment, you’re more likely to achieve them.

G. Losing weight, as well as getting a better job, is among the most popular resolutions for adults.
