These units only measure quantity: they do not measure the value of the food to the body. The unit which measures the quality or value of food is the calorie the amount of heat given off by food when it brurns. This measurement tells how much energy a certain food has when it is completely used by the body. Our bodies use varying amount of calories. The more exercise we take, the more calories we burn.

Read the following article and select the best answer. Article: Below is a selection from a popular science book. If blood is red, why are veins blue? Actually, veins are not blue at all. They are more of a clear, yellowish colour. Although blood looks red when it's outside the body, when it's sitting in a vein near the surface of the skin, it's more of a dark reddish purple colour. At the right depth, these blood-filled veins reflect less red light than the surrounding skin, making them look blue by comparison. Which works harder, your heart or your brain? This question depends on whether you're busy thinking or busy exercising. Your heart works up to three times harder during exercise, and shifts enough blood over a lifetime to fill a supertanker. But, in the long run, your brain probably tips it, because even when you're sitting still your brain is using twice as much energy as your heart, and it takes four to five times as much blood to feed it. Do old people shrink as they age? Yes and no. Many people do get shorter as they age. But, when they do, it isn't because they're shrinking all over. They simply lose height as their spine becomes shorter and more curved due to disuse and the effects of gravity . Many (but not all) men and women do lose height as they get older. Men lose an average of 3-4 cm in height as they age, while women may lose 5 cm or more. If you live to be 200 years old, would you keep shrinking till you were, like 60 cm tall, like a little boy again?No, because old people don't really shrink!It is not that they are growing backwards--their legs, arms and backbones getting shorter. When they do get shorter, it's because the spine has shortened a little. Or, more often, become more bent and curved. Why does spinning make you dizzy ? Because your brain gets confused between what you're seeing and what you're feeling. The brain senses that you're spinning using special gravity and motion sensing organs in your inner ear, which work together with your eyes to keep your vision and balance stable. But when you suddenly stop spinning , the system goes out... Question: Which of the following statements about our brain is TRUE? - In the long run, our brain probably works harder than our heart. - When our brain senses the spinning, we will feel dizzy. - The brains of the other mammals are as complex as those of humans. - Our feelings and emotions come from the most developed area in our brain.
(Answer)
In the long run, our brain probably works harder than our heart.
