Digestion in the Stomach by Howard F. Loomis Jr., D.C. Digestion begins in the mouth. When you chew your food it is mixed with saliva, which not only supplies moisture but also the carbohydrate-digesting enzyme, amylase. When you eat raw food, its enzymes work with the salivary amylase to begin digestion.
The U.S. Owes China $1.2 Trillion. China holds about $1.2 trillion in U.S. government debt, according to the Treasury Department's latest figures. That's about 30 percent higher than the previous estimate. This is part of those global imbalances we keep talking about.
How It Affects the U.S. Economy. China must buy so many U.S. Treasury notes that it is now the second-largest lender to the U.S. government. Japan is the largest. As of January 2017, the U.S. debt to China was $1.051 trillion. That's 28 percent of the total public debt owned by foreign countries. Many are concerned that this gives China political leverage over U.S. fiscal policy, since it could call in its loan.
