关于游牧和农耕民族的一个区别

不一定对。

游牧民族以肉食为主,获取食物的方式是狩猎和采集(蔬果类)所以多数运动的时候应该是空腹状态。能源的消耗以脂肪为主。食物无法囤积,在腊肉发明之前应该是这样的。所以为了生存,人的本能应该是时刻战备状态。

农耕民族获取食物的方式是种植,食物的开源是具有周期性,食物本身也可以囤积。所以生存的欲望和危机感可能和生活在牧场的人有点区别。

Oilve Oil is Low GI Foods

Benefits of Olive Oil

Olive oil is a fat and does not influence directly your blood sugar levels. If consumed as part of a meal though, olive oil, just like any other fat, can delay gastric emptying and helps smooth out your blood sugar response after your meal. Olive oil is also a source of monounsaturated fats, the heart-healthy fats that are prominent in the Mediterranean eating plan. The monounsaturated fats in olive oil can help lower your LDL cholesterol levels and reduce your risk of developing heart disease. In addition, olive oil, especially if it is cold-pressed and extra virgin, provides important polyphenols and vitamin E, which act as antioxidants to protect your body against the damages of oxidation.

Olive Oil

Olive oil is purely fat, it doesn’t contain any protein nor carbohydrates. For a food to have its glycemic index measured, it must contain carbohydrates. Because olive oil does not contain any carbohydrates(不包含任何碳水), it is impossible to assign a glycemic index value to this food. The same goes for any other oils or fat, such as canola oil, coconut oil, soybean oil, butter, cream, lard or mayonnaise. However, the fact that olive oil doesn’t have carbohydrates indicates that it won’t raise your blood sugar levels and its glycemic index value can therefore be estimated to be close to zero.
