D.Bylistingnumbers.loseweightNotallfatSomefat简单说，优质脂肪是身体“需要”的好脂肪，能帮身体干活；不优质脂肪是身体“怕多”的坏脂肪，吃多了伤身体。这类脂肪能调节血脂、保护心血管，还能帮身体吸收维生素。单不饱和脂肪常见来源：橄榄油、牛油果、坚果（核桃、杏仁）。特点：常温下多为液态，加热后相对稳定。多不饱和脂肪

分两种“必需脂肪酸”（身体自己造不出来，必须靠吃）：Omega-3：深海鱼（三文鱼,秋刀鱼）、去皮鸡胸肉/鸡里脊

亚麻籽、奇亚籽。能抗炎、保护大脑。Omega-6：大豆油、玉米油、葵花籽。适量有益，过量易引发炎症。一、优质脂肪（不饱和脂肪）简单说，优质脂肪是身体“需要”的好脂肪，能帮身体干活；不优质脂肪是身体“怕多”的坏脂肪，吃多了伤身体。饱和脂肪常见来源：肥肉、动物内脏、黄油、猪油。特点：常温下多为固态，吃多了会升高坏胆固醇，增加心血管疾病风险。反式脂肪（最“坏”的脂肪）常见来源：油炸食品（炸鸡、薯条）加工零食（饼干、薯片、方便面）、人造奶油。特点：人为加工出来的脂肪，会同时升高坏胆固醇、降低好胆固醇，对健康伤害最大。二、不优质脂肪（饱和脂肪+反式脂肪）“It’sOKtoeatonlywhatIlikewhileI’myoung.”Whenweareyoung,itmightfeellikewecanjusteatwhateverwewant!Forexample,sweetsandfriedfoodstastedelicious.Butwecannoteatthosefoodsalone.Eatingbalancedmealsisveryimportantwhenweareyoung.Ithelpsourbodyandbraintogrowwell.Badeatinghabitsmaystaywithusourwholelife,soitisbesttodevelopgoodeatinghabitsearly!ReadPara.3carefullyandanswerthequestions.Q1:Whyisitafoodmyth?Q2:Howdoesthewritersupporthisidea?A.Bygivingfacts.B.Bycomparingfacts.C.Bygivingexamples.
