Read the following passage and answer the questions that follow.
You may think that expecting food to change your life is too much to ask. But have you considered that eating the right food at the right time will increase energy, help you manage weight and ward off major illness?
Researchers have found that eating a meal with plenty of protein leaves you feeling more satisfied for longer when compared to a meal loaded with low-quality carbohydrates. Your body takes longer to digest protein, leading to a gradual increase in blood sugar. The high protein breakfast will therefore carry you through the morning and more importantly, through your tea break. Many high carbohydrate meals are absorbed quickly and send blood sugar on a roller coaster ride, taking your appetite with it and depleting your energy.
Many foods contain antioxidants, but fruits and vegetables may be the richest source. Behaving like chemical warriors,
antioxidants neutralize molecules known as free radicals before they damage arteries and body cells. This protects you from heart diseases, high blood pressure, cancer and diabetes. You can now see why antioxidant foods should be consumed in generous portions.
Actually, forget pills - antioxidants work best when consumed in foods. In fact, nutritionists recommend that we eat five
portions of fruit and vegetables a day. It's less daunting than it sounds: a portion equals a piece of fruit, three tablespoons of cooked vegetables or a glass of fresh juice.
And do you desire to relive yourself of some baggage? Calcium is the latest weight-loss star to appear on the scene.
Scientists stumbled on its magic by accident. From study that measured the blood pressure of obese people, it was discovered that those who took one large tub of yoghurt a day in their diet lost an average of eleven pounds of body fat in one year, even though they did not eat less.
A follow-up study found that people on a high calcium diet lost weight and fat than did people on a low-calcium diet - and again, both consumed the same number of calories. Researchers believe calcium encourages fat cells to stop “getting fatter” instead, the cells burn extra fat without you having to go anywhere near a gymnasium.
It probably sounds strange to say that you can cat more in order to lose weight. Obviously, the question you should ask
immediately is, “Eat more of what?' We are talking about foods rich in fibre. They have what is referred to as low-energy density; that translates to few calories relative to weight. This means that you can down a mountain without fear of calories overload.
Fibre also aids weight loss because it's filling. Most high-fibre foods take a lot of chewing, triggering your body?s fullness sensors. Moreover, you absorb the food more slowly so you feel full longer.
Will the wonders of food ever cease? Not if researchers in nutrition keep their pace.
Let them keep the good news flowing - such as the fact that we don't have to starve ourselves to lose weight and keep diseases at bay.
