Unit 2 Healthy eating Research has shown that following a healthy eating plan can both reduce the risk of developing high blood pressure and lower already elevated blood pressure. For an overall eating plan，consider the DASH eating plan.“DASH” stands for “Dietary Approaches to Stop Hypertension”，a clinical study that tested the effects of nutrients in food on blood pressure.Study results indicated that elevated blood pressure was reduced by an eating plan that emphasizes fruits，vegetables，and low-fat dairy foods and is low in saturated fat，total fat，and cholesterol.The DASH eating plan includes whole grains，poultry，fish，and nuts and has reduced amount of fats，red meats，sweets，and sugared beverages. A second clinical study，called “DASH-Sodium”，looked at the effect of a reduced dietary sodium intake on blood pressure as people followed either the DASH eating plan or a typical American diet.Results showed that reducing dietary sodium lowered blood pressure for both the DASH eating plan and the typical American diet.The biggest blood pressure-lowering benefits were for those eating the DASH eating plan at the lowest sodium level (1,500 milligrams per day). The DASH-Sodium study shows the importance of lowering sodium intake whatever your diet is.But for a true winning combination，follow the DASH eating plan and lower your intake of salt and sodium. 1.elevate vt.提升 2.nutrient n.营养品；adj.营养的 3.cholesterol n.胆固醇 4.beverage n.饮料 5.sodium n.钠 判断正(T)误(F) 1.Healthy eating may make some difference to blood pressure.(T) 2.The DASH eating plan aims to low fat.(F) 3.A typical American diet is a healthy one.(F) 4.High sodium intake will risk the high blood pressure.(T) Period One　Warming Up，Pre-reading Reading Ⅰ.单词检测 1.diet n.日常饮食；vi.节食 2.balance vt.平衡；权衡；n.天平；平衡 3.fry vt.v.油煎；油炸 4.slim vi.变细；减肥；adj.苗条的；纤细的 5.curiosity n.好奇心 curious adj.好奇的 6.lie n.谎话；谎言；vi.说谎 7.customer n.顾客；消费者 8.discount n.折扣 9.weakness n.缺点；虚弱；弱点 weak adj.虚弱的；无力的 10.strength n.强项；长处；力量 strong adj.坚强的
