Nutrition is the study of nutrients in food, how the body uses them, and the relationship between diet, health, and disease. Nutritionists use ideas from molecular biology, biochemistry, and genetics to understand how nutrients affect the human body.

The saying goes that good things come in small packages, and that is especially true when it comes to nutrition. There are two major classes of nutrients in food: macronutrients and micronutrients. Macro means big, and macronutrients take their name from the fact they make up the bulk of the nutrition in the food: carbohydrates, protein, and fat.

To maintain your brain, muscle, bone, nerves, skin, blood circulation, and immune system, your body requires a steady supply of many different raw materials—both macronutrients and micronutrients. You need large amounts of macronutrients—proteins, fats, and carbohydrates. And while you only need a small number of micronutrients—vitamins and minerals—failing to get even those small quantities virtually guarantees disease.

Micronutrient Facts

A classify nutrients, their functions, and food sources and compare the nutritive value of various foods; B assess the effects of nutritional intake on health, appearance, effective job performance, and personal life; C analyze and apply various dietary guidelines throughout the life cycle, including pregnancy, infancy, childhood, and late adulthood; and D compare personal food intake to recommended dietary guidelines. Nutrients are the chemical substances in the foods we eat. Our bodies use these nutrients for energy and to support growth, maintenance, and repair of tissues. Essential nutrients are those which our bodies need and must be provided through the foods we eat. There are six major groups of nutrients: carbohydrates, fats and oils, proteins, vitamins, minerals, and water. Macronutrients provide energy so they are needed in greater amounts. Sources of carbohydrates include breads, cereal grains, pasta, rice, fruit, vegetables, milk, and sugar.

Human nutrition

Due to control of florid and severe cases of protein-energy malnutrition, deficiencies of micronutrients in children have assumed public health importance. Over two-third of children have clinical evidences of iron deficiency while deficiency of trace minerals like iodine and zinc is quite common in certain populations. Children have food preferences and they are quite fussy to take green leafy vegetables and fruits thus compromising their intake of micronutrients from dietary sources. Micronutrients are required for the integrity and optimal functioning of immune system. Children with subclinical deficiency of micronutrients are more vulnerable to develop frequent and more severe common day-to-day infections thus triggering a vicious cycle of undernutrition and recurrent infections. A number of micronutrients are required for optimal physical growth and neuromotor development. Isolated deficiencies of micronutrients are rare in clinical practice and usually deficiencies of multiple micronutrients co-exist.

Human nutrition deals with the provision of essential nutrients in food that are necessary to support human life and good health. The human body contains chemical compounds such as water, carbohydrates, amino acids found in proteins , fatty acids found in lipids , and nucleic acids DNA and RNA. These compounds are composed of elements such as carbon, hydrogen, oxygen, nitrogen, and phosphorus. Any study done to determine nutritional status must take into account the state of the body before and after experiments, as well as the chemical composition of the whole diet and of all the materials excreted and eliminated from the body including urine and feces. The seven major classes of nutrients are carbohydrates , fats , fiber , minerals , proteins , vitamins , and water. Carbohydrates, fats, and proteins are macronutrients, and provide energy.

What is nutrition, and why does it matter?

Micronutrients are one of the major groups of nutrients your body needs. They include vitamins and minerals. Vitamins are necessary for energy production, immune function, blood clotting and other functions. Meanwhile, minerals play an important role in growth, bone health, fluid balance and several other processes. This article provides a detailed overview of micronutrients, their functions and implications of excess consumption or deficiency.

Micronutrients, often referred to as vitamins and minerals, are vital to healthy development, disease prevention, and wellbeing.

Вот бы побывать здесь вместе со Сьюзан. - И, разумеется, Христофора Колумба? - просиял лейтенант.  - Он похоронен в нашем соборе. Беккер удивленно посмотрел на. - Разве. Я думал, что он похоронен в Доминиканской Республике.

 Отпусти меня! - попросил Хейл.  - Я ничего не сделал. - Ничего не сделал? - вскричала Сьюзан, думая, почему Стратмор так долго не возвращается.

Это могло оказаться лучшей новостью за весь день. Смит потянулся к объективу камеры, чтобы направить его в глубь кузова. На экране промелькнула внутренняя часть мини-автобуса, и перед глазами присутствующих предстали два безжизненных тела у задней двери. Один из мужчин был крупного телосложения, в очках в тонкой металлической оправе с разбитыми стеклами. Второй - молодой темноволосый, в окровавленной рубашке.

Мостовая стремительно убегала назад в нескольких дюймах внизу. Он окончательно протрезвел. Ноги и плечо ныли от боли. Беккер с трудом поднялся на ноги, выпрямился и заглянул в темное нутро салона. Среди неясных силуэтов впереди он увидел три торчащие косички. Красная, белая и синяя.

В помещении царила атмосфера полного хаоса. Сьюзан завороженно смотрела на захватывающую дух технику. Она смутно помнила, что для создания этого центра из земли пришлось извлечь 250 метрических тонн породы. Командный центр главного банка данных располагался на глубине шестидесяти с лишним метров от земной поверхности, что обеспечивало его неуязвимость даже в случае падения вакуумной или водородной бомбы. На высокой рабочей платформе-подиуме в центре комнаты возвышался Джабба, как король, отдающий распоряжения своим подданным. На экране за его спиной светилось сообщение, уже хорошо знакомое Сьюзан. Текст, набранный крупным шрифтом, точно на афише, зловеще взывал прямо над его головой: ТЕПЕРЬ ВАС МОЖЕТ СПАСТИ ТОЛЬКО ПРАВДА ВВЕДИТЕ КЛЮЧ_____ Словно в кошмарном сне Сьюзан шла вслед за Фонтейном к подиуму.

Компьютер немедленно распознал частоту ее голоса, и дверь, щелкнув, открылась. Сьюзан проследовала .

 Echo un poco de Smirnoff? - настаивал бармен.  - Плеснуть чуточку водки. - No, gracias. - Gratis? - по-прежнему увещевал бармен.

 Не знаете, как его зовут. Клушар на мгновение задумался и покачал головой: - Понятия не имею.  - Он поморщился от боли и откинулся на подушки. Беккер вздохнул.
