Nuts(堅果)內含有很多不飽和脂肪，也含有飽和脂肪

FDA only approved the heart health claim for almonds, hazelnuts, peanuts, pecans, some pine nuts, pistachios and walnuts as these nuts contain less than 4g of saturated fats per 50g. However that doesn't mean you should restrict yourself to these 7 nuts only. In addition to nuts, seeds such as flax seeds, pumpkin seeds and sunflower seeds may offer the same heart he alth benefits. Again moderation is the key - limit your intake to 1 to 2 oz of unsalted nuts per day. --- from http://www.healthcastle.com/nuts-benefits.shtml
美國FDA推薦的7種堅果，每50公克中含有小於4公克得飽和脂肪，即小於8%，數量不多，不用排拒，人體也需要飽和脂肪修補細胞。
