Ha Noi, the capital of Vietnam, is one of the most interesting destinations for domestic and foreign tourists. Among many attractions are the craft villages. There are about 1500 handicraft villages recognized in Viet Nam, and about 300 are traditional handicraft villages. The heartland of craft villages is the Red River Delta, and particularly around Ha Noi. Ha Noi is home to more than 45 percent of the nation’s total number.

How were those craft villages set up? Years ago, after harvest time, Vietnamese villagers used natural materials, such as clay, bamboo, wood, and some certain kinds of plants and leaves to make craft things for their family’s daily needs. Gradually, they made their handicrafts more and more perfect, and then sold them to others around the village to get extra income. The ways to make handicrafts have been passed down from generation to generation. Family members, relatives, and friends work together. Those artisans never compete but help one another to do better business. Each craft village has its trademark name of handicraft products.

The government has organized marketing offices, agencies, and design centers to introduce handicrafts to everyone so that the artisans can sell their products. Today, many ceramic, porcelain, bamboo, rattan, wood, and lacquer products from handicraft villages are sold as souvenirs throughout the country.

     Although they are an inexpensive supplier of vitamins, minerals, and high-quality protein, eggs also contain a high level of blood cholesterol, one of the major causes of heart diseases. One egg yolk, in fact, contains a little more than two-thirds of the suggested daily cholesterol limit. This knowledge has caused egg sales to plummet in recent years, which in turn has brought about the development of several alternatives to eating regular eggs. One alternative is to eat substitute eggs. These egg substitutes are not really eggs, but they look somewhat like eggs when they are cooked. They have the advantage of having low cholesterol rates, and they can be scrambled or used in baking. One disadvantage, however, is that they are not good for frying, poaching, or boiling. A second alternative to regular eggs is a new type of egg, sometimes called 'designer' eggs. These eggs are produced by hens that are fed low-fat diets consisting of ingredients such as canola oil, flax, and rice bran. In spite of their diets, however, these hens produce eggs that contain the same amount of cholesterol as regular eggs. Yet, the producers of these eggs claim that eating their eggs will not raise the blood cholesterol in humans.

Egg producers claim that their product has been portrayed unfairly. They cite scientific studies to back up their claim. And, in fact, studies on the relationship between eggs and human cholesterol levels have brought mixed results. It may be that it is not the type of egg that is the main determinant of cholesterol but the person who is eating the eggs. Some people may be more sensitive to cholesterol derived from food than other people. In fact, there is evidence that certain dietary fats stimulate the body's production of blood cholesterol. Consequently, while it still makes sense to limit one's intake of eggs, even designer eggs, it seems that doing this without regulating dietary fat will probably not help reduce the blood cholesterol level.
