People drink alcohol(酒) in many parts of the world. Some medical scientists say light drinking may even be good for your health, especially for the heart. But they say such health benefits(好处) should be compared to the many health risks connected with alcohol use.
Some research suggests that having one to two drinks of alcohol a day may be good for your health. Several large studies have shown that this type of drinking may lower the risk of heart disease and other diseases.
A study last year suggested that drinking a little red wine may help lower the risk of breast cancer(乳腺癌) in women. Researchers at Medical Center in California studied 36 women. Each woman drank a glass of red or white wine every day for almost a month. Researchers collected blood samples(样本) from the women two times a month to test their hormone(激素) levels. The next month these women were told to exchange their wine. The researchers found that the women who drank red wine had lower levels of the female hormone than the white wine drinkers. They said red grapes have chemicals that may help to lower the risk of breast cancer.
However, recent studies suggested that even a little alcohol may generally increase the risk of breast cancer in women. They found that women who drink four small glasses of wine a week increase their risk of breast cancer by 15 percent.
Many studies have examined the harmful effects of alcohol use on the body. Alicia Ann Kowalchuk serves as medical director, saying “Healthy use for adults --- that's men under age 65 --- is no more than 4 drinks in a day and no more than 14 drinks in a week. And for women of all ages, it's no more than 7 drinks in a week and no more than 2 drinks in a day.” She says too much alcohol use has something to do with liver (肝脏) diseases, and many other cancers.

My kids and I were heading into the supermarket over the weekend. On the way, we saw a man holding a piece of paper that said, “Lost my job. Family to feed.”
At this store, a scene like this is not normal. My 10-year-old son noticed him and made a comment(评论) on how bad it must be to have to stand outside in the cold wind.
In the store, I asked each of my kids to pick something they thought our “friend” there would like. They got apples, a sandwich and a bottle of juice. Then my 17-year-old son suggested giving him a gift card. I thought about it. We didn’t have much money ourselves, but … well, sometimes giving from our need instead of our abundance(充裕) is just what we need to do! All the kids declared(宣称) something they could do away with for the week.
When we handed him the bag of food, he lit up and thanked us with wet eyes. When I handed him the gift card, saying he could use it for whatever his family might need, his eyes were filled with tears.
This has been a wonderful experience for our family. For days the kids have been looking for others we can help! Things would have played out so differently if I had simply said, “No, we really don’t have money to give more.” Stepping out not only helped a brother in need, it also gave my kids the sweet taste of helping others. It’ll go a long way with them.
