A close look at global diets reveals a lot about the diverse cultures that exist in harmony in the modern world. Food is, after all, a common binding factor across political and physical boundaries.  In most countries, the staple food has remained consistent over the passing decades. This includes rice, corn, soybean, wheat and pulses.
The United Nations reports a 37% increase in food prices globally in the past year. It has become increasingly difficult for an average world citizen to put a healthy and nutritious meal on their dinner table. In fact, research indicates that people have changed their diet because of health reasons and due to food inflation.

By and large, ethnic foods make use of seasonal produce. This makes meals healthy and nourishing, as ingredients are consumed fresh, soon after they come from the fields. Recipes and the style of cooking is observed to be distinct in geographical regions. They are most often associated with the climate and terrain, and the food that is grown in the area. Regional recipes make use of spices and condiments that are locally produced or available.
With increase in cross cultural interaction, people are willing to try dishes and recipes from foreign lands, and hence, the emergence of world foods. The internet has also made it easy for people to find the recipes for global foods and ethnic ones too. So, you can easily find excellent Indian curry when you are in America, as you would find authentic Italian pizza in Australia or the Middle East. Supermarkets also stock ingredients that are not typical to ethnic dishes and required for world foods.

Global diets indicate an increase in the consumption of processed foods. These have been related to conditions such as high blood pressure, diabetes, obesity and heart disease. Hence, in many cultures people prefer to return to ethnic foods that use organic ingredients.
