A substance consumed by organisms to obtain energy and other nutrients. Food is usually of plant or animal origin and may be eaten raw or cooked. It can also be preserved by freezing, salting, smoking, or pickling. The types of food available to people vary widely depending on the culture and geographic location. For example, sea foods are popular in coastal regions and potatoes are a staple crop in cold climates.
In addition to its nutritional value, food often plays a role in culture and society. It is used as a medium for socializing and bonding and is frequently included in rituals and traditions. The act of preparing and eating food can also be relaxing and enjoyable.
Eating well is one of the best things you can do for your health. Choose whole foods and limit processed foods and added sugars. Look for foods that are low in saturated fats and sodium (salt) and high in fiber, vitamins, and minerals. Choose lean proteins, such as beans and lentils, fish, poultry, skinless chicken, and soy products, along with fruits, vegetables, whole grains, and dairy products. Aim for a variety of colors when choosing produce and choose organic or sustainably raised options when possible.
Many factors can influence diet, including geography, culture, economics, and religion. People living in cool regions with short growing seasons often eat more fish than those in warmer climates, while those who live in areas with abundant supplies of fresh water may eat less meat. Many people follow a religion that requires them to abstain from certain foods or prepare and cook their meals in a specific way.
The food supply has a major impact on the world’s economies, and the agriculture and food industries are responsible for many jobs worldwide. The food industry has evolved to meet the increasing demands for convenient and affordable meals. The resulting changes in eating habits have contributed to weight gain and increased incidence of some diseases.
In many homes, time to enjoy nutritious meals can get pushed aside when life gets busy. Take the time to plan ahead and stock your kitchen with healthy foods that are easy to prepare. Include staples like frozen or canned vegetables, dried and canned fruits, low-sodium broth, tins of tomatoes, quinoa, brown rice, beans and lentils, and lean proteins. Keep prepped items front and center in your fridge and pantry, and make sure to label and rotate them as needed. Be sure to purchase foods with the lowest amount of sodium and sugar, and seek out options that are Certified USDA Organic or Non-GMO Project verified, Fair Trade Certified, or free-range or pasture-raised. These options are usually healthier and more sustainable for the environment. They may also cost less and be easier to find in stores. If you have a food allergy or intolerance, consult a registered dietitian for personalized advice about your food choices. They can help you create a plan to manage your condition and improve your overall eating habits.
