DESCRIPTION

 酒精與 膳食纖維. 酒精. 酒精(乙醇 CH3CH2OH ) 酒精的熱含量相當高,每一克酒精燃燒會放出 7.1 卡的能,可是酒精這麼高的熱含量在體內卻絲毫不發生作用,因不能和體內產生能量的系統相連接,稱之為「空卡」( empty calories )。 酒精會刺激胃、腸和其它消化器官,降低消化和吸收的能力,酒精和它的代謝物乙醛又可以減低維生素的功能。. 肝臟有氧化酒精的酵素. 肝臟中氧化,因為只有肝細胞中才含有大量能氧化酒精的酵素。 酒和其他的食物一樣,可以被腸、胃等消化器官吸收,但不能儲存在組織中,也不能經由肺臟和腎臟排出體外,在體內只有靠氧化作用分解它。. - PowerPoint PPT Presentation

  • alcohol is both a tonic and a poison. The difference lies mostly in the dose. Moderate drinking seems to be good for the heart and circulatory system, and probably protects against type 2 diabetes and gallstones. Heavy drinking is a major cause of preventable death in most countries.

  • one drink per day for menIn the U.S., one drink is usually considered to be 12 ounces of beer, 5 ounces of wine, or 1 ounces of spirits (hard liquor such as gin or whiskey). Each delivers about 12 to 14 grams of alcohol. one to two drinks per day for men, and no more than one drink per day for women.

  • Health Effects of Eating Fiber fiber appears to reduce the risk of developing various conditions, including heart disease, diabetes, diverticular disease, and constipation. Despite what many people may think, however, fiber probably has little, if any effect on colon cancer risk.

  • Some tips for increasing fiber intake:Eat whole fruits instead of drinking fruit juices. Replace white rice, bread, and pasta with brown rice and whole-grain products. Choose whole-grain cereals for breakfast. Snack on raw vegetables instead of chips, crackers, or chocolate bars.

  • Some tips for increasing fiber intake:2Substitute legumes for meat two to three times per week in chili and soups. Experiment with international dishes (such as Indian or Middle Eastern) that use whole grains and legumes as part of the main meal (as in Indian dahls) or in salads (for example, tabbouleh).

  • Current recommendations Adults consume 20-35 grams of dietary fiber per day. Children over age 2 should consume an amount equal to or greater than their age plus 5 grams per day. Yet the average American eats only 14-15 grams of dietary fiber a day.

  • high dietary fiber intakeA high total dietary fiber intake was linked to a 40 percent lower risk of coronary heart disease, compared to a low fiber intake.Fiber intake has also been linked with the metabolic syndrome, a constellation of factors that increases the chances of developing heart disease and diabetes.

  • Fiber intake These factors include high blood pressure, high insulin levels, excess weight (especially around the abdomen), high levels of triglycerides, the body's main fat-carrying particle, and low levels of HDL (good) cholesterol.Several studies suggest that higher intake of fiber may somehow ward off this increasingly common syndrome.

  • Foods with a low glycemic index do not raise blood sugar levelsFoods that have a high glycemic index include potatoes, refined foods such as white bread, white rice, refined cereals (corn flakes, Cheerios), white spaghetti, and sugar. Foods with a low glycemic index do not raise blood sugar levels as quickly and, therefore, are associated with a lower risk of type 2 diabetes. Low glycemic index foods include legumes, whole fruits, oats, bran, and whole-grain cereals.

  • 40 percent lower risk of diverticular diseasefiber absorbs water When it comes to factors that increase the risk of developing diabetes, a diet low in cereal fiber and rich in high glycemic index foods (which cause big spikes in blood sugar) seems particularly bad.eating dietary fiber, particularly insoluble fiber, was associated with about a 40 percent lower risk of diverticular disease.

  • fiber seems to relieve and prevent constipationThe gastrointestinal tract is highly sensitive to dietary fiber, and consumption of fiber seems to relieve and prevent constipation. The fiber in wheat bran and oat bran seems to be more effective than similar amounts of fiber from fruits and vegetables. Experts recommend increasing fiber intake gradually rather than suddenly.

  • for men, that translates into drinking roughly 12 8-oz. glasses of waterWomen generally need to consume 91 ounces of water each day from beverages and foods, while men generally need to consume 125 ounces each day. People typically obtain about 80 percent of their water from beverages (including beverages that contain caffeine) and 20 percent of their water from foods. So for women, that translates into drinking 9 8-oz. glasses of water or other beverages each day and obtaining another 18 ounces of water from foods; for men, that translates into drinking roughly 12 8-oz. glasses of water or other beverages each day, and obtaining another 25 ounces of water from foods.

  • 20-35 grams of dietary fiber per day for adults.Fiber is an important part of a healthy diet, and you should get a least the minimum recommended amount of 20-35 grams of dietary fiber per day for adults. For children over age 2, the recommended intake is the child's age + 5 grams. The best sources are fresh fruits and vegetables, nuts and legumes, and whole-grain foods.
