The Nutritional Value of Food
Food is any material consumed to give nutrition to organisms. More specifically, food is generally of animal, plant or microbial origin, and has the necessary nutrients, including proteins, carbohydrates, vitamins, or minerals, which the body needs in order to survive. Humans need a variety of different types of food to maintain a healthy weight and to meet the daily energy requirements for their active lifestyle. With today’s food sources are becoming more expensive and less abundant, most people are turning to the healthy alternative of raw foods or food such as homemade food, that can be prepared at home or in large scale commercial facilities. However, food processing methods have made it possible to produce food products that are highly nutritious, yet less costly than home-cooked meals.
In addition to the wide range of commercially processed foods available, there are many nutritionally rich, organic foods available in local food stores. These foods help to strengthen the body’s ability to fight off disease and maintain a healthy immune system. The combination of strong-quality foods, a balanced diet and a regular exercise program have been shown over time, to help individuals maintain a higher quality of life and lead healthier, happier lives.
When it comes to maintaining a healthy weight, food plays a major role. People who eat a balanced diet and exercise regularly will usually stay within the recommended weight for their height and age. However, many people who are overweight do not follow a healthy eating plan, and end up becoming obese, which puts them at risk for a variety of diseases such as high blood pressure, heart disease, stroke, diabetes, cancer, and even some types of cancer. Eating a diet rich in fruits, vegetables, whole grains and low fat dairy products, along with a vigorous exercise program not only helps to reduce weight, but also helps to maintain the ideal weight for most individuals.
In addition to helping individuals to lose weight, foods that are high in sugar can cause a variety of problems. Sugary snacks are often eaten when we are waiting for a bus, waiting for a taxi or waiting for our turn at a store. While sugary foods are naturally sweet, the calories from them add up over time, resulting in weight gain. Excess weight can be avoided by eating a diet that is rich in fiber and other nutrients.
Fats are commonly found in fried foods, as well as meats. There is a saying, “you are what you eat.” In other words, if you consume high amounts of animal fat and red meat, you may become prone to high cholesterol, diabetes, cancer and other health complications. In addition to adding fats to your diet, you should limit your consumption of sugary foods, fried foods, processed foods, fast food and foods that contain preservatives. This will help you keep your blood sugar levels stable and help to maintain good health, as well as prevent illness.
Vegetables, seeds and fruits are the richest in nutrients, antioxidants and phytochemicals, which are very powerful antioxidants. They provide many essential vitamins and minerals. When combined with healthy oils, these vegetables, nuts and fruits can provide an endless array of delicious foods that provide energy, including fuel for weight loss. If you add whole grains to your diet, you can get tons of other nutrients that will help you maintain a healthy body and a strong immune system.
