Nutrition: Food provides people with the necessary energy and nutrients to be healthy. By eating a variety of foods, including good quality vegetables, fruits, whole-grain products, and lean meats, the body can replenish itself with the essential proteins, carbohydrates, fats, vitamins, and minerals to function effectively. Nutrients include proteins, carbohydrates, fats, vitamins, minerals, and water. Healthy eating does not have to be difficult. The key is to eat a variety of foods, which include fruits, vegetables, and whole-grains. Eat lean meats, poultry, fish, beans, and low-fat dairy products and drink lots of water. Limit salt, sugar, alcohol, saturated fat, and trans fat. Saturated fats usually come from animals. Look for trans fat on the labels of processed foods, margarine, and shortenings. Dr. Alex Jimenez offers nutritional examples as well as describes the importance of balanced nutrition, emphasizing how a proper diet combined with exercise and physical activity can help individuals reach and maintain a healthy weight, reduce their risk of injuries and conditions, such as sciatica, and promote overall health and wellness.
