A necessary part of everyone’s daily life! Make smart nutrition choices! The main message is to focus on diet quality!
In order to stay healthy and full of energy, it is best to have a good diet. The key to a happy life represents what you eat and how you train your body.
The diet of an organism is what it eats, which is largely determined by the availability, the processing, and palatability of foods. A healthy diet includes preparation of food and storage methods that preserve nutrients from oxidation, heat or leaching, and that reduce the risk of foodborne illness.
Nutrition is the science that interprets the interaction of nutrients and other substances in food in relation to maintenance, growth, reproduction, health and disease of an organism. It includes food intake, absorption, assimilation, biosynthesis, catabolism, and excretion.
The first recorded dietary advice, carved into a Babylonian stone tablet in about 2500 BC, cautioned those with pain inside to avoid eating onions for three days. Scurvy, later found to be a vitamin C deficiency, was first described in 1500 BC in the Ebers Papyrus.
There are two types of nutrients! Macro-nutrients which are needed in relatively large amounts, and micronutrients which are needed in smaller quantities.
The macronutrients are carbohydrates, fiber, fats, protein, and water. The micronutrients are minerals, vitamins, and others.
Healthy oils (like olive and canola oil) are recommended for cooking, on salads, and at the table. Limit butter. Avoid trans fat.
Saturated fats are usually fats that come from animals. Look for trans fat on the labels of processed foods, margarine, and shortenings.
Water, tea or coffee should have a low amount of sugar or none. Limit milk/dairy (1-2 servings per day) and juice, only 1 small glass every day. Avoid sugary drinks.
Whole grains. A person can eat a variety of grains, like whole-wheat bread, whole-grain pasta, brown rice. Limit refined grains, like white rice and white bread.
Vegetables. The more veggies and the greater the variety the better. Potatoes and french fries don’t count.
Fruits. Eat plenty of fruits of all colors.
Healthy protein. Choose fish, poultry, beans, and nuts. Limit red meat and cheese. Avoid bacon, cold cuts, and other processed meats.
Use this healthy eating as a guide. Create healthy and balanced meals every time. Served on a plate or packed in a lunch box always eat fresh.
Nutritional science studies how the body breaks food down (catabolism) and repairs and creates cells and tissue (anabolism) – catabolism and anabolism = metabolism. This science also examines how the body responds to food.
In addition, nutrition involves identifying how certain diseases, conditions or problems may be caused by dietary factors, such as poor diet (malnutrition), food allergies, metabolic diseases, etc.
Major food manufacturers employ nutritionists and food scientists. Nutritionists may also work in journalism, education, and research. Many nutritionists work in the field of food science and technology.
There is a lot of overlap between what nutritionists and dietitians do and studied. Some of them work in health care, some dietitians work in the food industry, but a higher percentage of nutritionists work in the food industry and food science and technology, and a higher percentage of dietitians work in health care.
One could very loosely generalize and say that a nutritionist focuses firstly on a food, and then looks at its effects on people, while a dietician looks at the human, and then how that human’s health is influenced by food.
Nutrition is present in all processes of life. Right from the very moment the sperm fertilizes an egg, through fetal development in the uterus, to the birth, human growth, maturity, old age, and eventual death.
Even after death, the human body serves as nutrition for other organisms. Anything that involves life and chemical or biochemical movement has nutrition at its core.
Anything that lives is dependent on energy, which results from the combustion of food.
Dietetics is the interpretation and communication of the science of nutrition so that people can make informed and practical choices about food and lifestyle, in both health and disease.
Part of a dietician’s course includes both hospital and community settings. The majority of dietitians work in health care, education and research, while a much smaller proportion also works in the food industry.
