- This typical office worker looks very nutritious and has plenty of calories. But I do not know why, this rich breakfast does not allow many people to support noon. After research, the nutritionists of the British Food Commission found that the cause of the increase in hunger was black tea and coffee. Sun Meifang, director of nutrition department of Shanghai Ninth People's Hospital, pointed out that both of these foods contain caffeine, which can stimulate the adrenal gland to produce adrenal hormones. It can make people excited in the short term and seems to be full of energy. However, with the decline of adrenal hormones, the body will quickly return to fatigue, and people will soon feel hungry. Experts believe that one day should ensure that 1.5 to 2 liters of water intake, but both tea and coffee have a diuretic effect, so in fact can not effectively help the body to add water. Therefore, for office workers with a tight pace of life and work pressure, breakfast is best to drink less black tea and coffee. 4-Layer KN95 Protective Face Mask,Folding KN95 Face Mask,Dust Protect Kn95 Face Mask,3D KN95 Face Cover Dongguan Keyutai Mask Co., Ltd. , https://www.maskkytai.com
