When you look at your meals, some ingredients (原料) are easy to see. But your meals are also filled with ingredients you can’t see.
Salt is a perfect example of an ingredient that you might not notice, even when you eat a lot of it. But it’s the salt we can’t see that concerns scientists most. For years, doctors have warned patients that too much salt can be bad for their health. Heart trouble has long been considered a grown-up problem. New research suggests that salt is starting to affect kids. And salt isn’t the only cause of high blood pressure. Eating lots of junk food, weighing too much and exercising too little also contribute to high blood pressure.
As part of the studies, hundreds of adults ate exactly what researchers told them to. These studies lasted for months at a time. The results showed a large drop in blood pressure in people who ate extra fruits and vegetables, lots of whole grains, low-fat dairyproducts (奶制品) and only small amounts of red meat. Eating well, the researchers concluded, is good for your heart. What’s more, studies from around the world show that high blood pressure and heart disease rates are lowest in the places where people eat the least amount of salt and lots of vegetables.
The best way to reduce the amount of salt you take, researchers say, is to make changes gradually. Start by dropping half as much salt in your dinner as you normally do. Switch to fresh foods instead of canned and bottled ones. “Kids today need to give salt the shake,” says David Grotto, a doctor in Chicago, “in order to keep healthy.”
