To win is to be #1 in a competition, or to receive an award. My soccer team won the game 3-1. I want to win the lottery! John won a prize in the science competition.
You can win a game, a race, a match, a competition, or the lottery. You can also win a medal (like in the Olympics), a prize, or an award.
To earn something is to get something in exchange for your work or effort, for example: a salary. Sarah is a famous lawyer; she earns a lot of money. I'm not rich, but I earn a decent salary. My bank account earns 2% interest per month.
To gain something is simply to get or increase - not necessarily because of action: I've gained five pounds since I stopped exercising. Jack's car gained speed as he drove down the mountain. The company is gaining international recognition.
Milk and Skim Milk
A recent study found that calcium from dairy foods (1000 to 1400 milligrams per day) changes the way the body burns fat, increasing the metabolism of fat. This helps explain how skim milk not only provides sound nutrition, but may also help you lose weight.
Fat-free milk is high in protein, calcium, and the B vitamins, including B12. If you are still drinking whole milk, switching to nonfat milk can be a significant move toward healthier living all by itself. Not only will you cut fat intake and calories, but you’ll get more protein and vitamins in place of the fat. Start by switching from whole milk to 2 percent, then to 1 percent, and finally to skim milk.Nutritional Facts
