Foods and nutrients. A food is something that provides nutrients. energy for activity, growth, and all functions of the body such as breathing, digesting food, and keeping warm; materials for the growth and repair of the body, and for keeping the immune system healthy.
Your food choices each day affect your health — how you feel today, tomorrow, and in the future. Combined with physical activity, your diet can help you to reach and maintain a healthy weight, reduce your risk of chronic diseases (like heart disease and cancer), and promote your overall health.
Plants and animals are the main source of food for all the organisms on earth. Food obtained from animals is the main source of protein and include fish, milk, meat, poultry, and cheese. Whereas plants provide us with fruits and vegetables which are an important source of fibres, proteins and carbohydrates.
Protein builds, maintains and repairs body tissue. It is especially important for growth. In the United States, most children do not suffer from lack of dietary protein. It is important, to encourage children to eat two to three servings of meat, fish, poultry or other protein-rich food each day.
Nitrates: Processed foods contain a large amount of nitrates. Fat: Most processed food contains a lot of fat. This is generally saturated fat, which can increase LDL cholesterol. Sugar: Processed foods are also generally high in sugars, which can make them very high in calories.
We can't live on air and sunshine alone. The human body needs food and water to survive. Water acts as a lubricant for our joints, regulates our body temperature through sweating and respiration, and helps to flush waste.
Water carries nutrients to all cells in our body and oxygen to our brain. Water allows the body to absorb and assimilate minerals, vitamins, amino acids, glucose and other substances. Water flushes out toxins and waste. Water helps to regulate body temperature.
To stay alive, the organism takes in important materials for making energy, while shuttling out toxic substances such as waste products. In this regard, water is essential simply because it's a liquid at Earth-like temperatures. The humble water molecule is made up of two hydrogen atoms bonded to an oxygen atom.
The National Academies of Sciences, Engineering, and Medicine determined that an adequate daily fluid intake is: About 15.5 cups (3.7 liters) of fluids for men. About 11.5 cups (2.7 liters) of fluids a day for women.

Water helps your kidneys remove waste from your blood. If you don't get enough water, that waste -- along with acids -- can build up. That can lead to your kidneys getting clogged up with proteins called myoglobin. Dehydration can also lead to kidney stones and urinary tract infections.

Just as a power station requires gas or coal to power its turbines and generate energy, so we need fuel – in the form of food – to power our continued existence. The foods we eat provide us with a range of nutrients: vitamins, minerals, water, fat, carbohydrates, fibre, and protein.
Eat these foods daily (or at least often)
