Ensure is a nutritional supplement drink that can help support weight gain, healthy aging, and recovery from surgery. It also provides balanced nutrition and promotes bone health.
Ensure is available as a powder, and it can be mixed with water or milk. It’s suitable for lactose-intolerant individuals and those on a gluten-free diet.
Proteins are a key macronutrient in your diet, and it’s important to include them. It helps your body in a variety of ways, such as building lean muscle mass, healing and repairing tissues, providing energy and aiding blood sugar and weight control.
Most people need between 10 and 35 percent of their calories in the form of protein, according to the Institute of Medicine (IOM). Getting enough is especially important for endurance athletes or power and strength training athletes.
Meat, poultry, fish and eggs are all good sources of protein. Plant-based foods such as beans, peas, seeds and nuts also provide protein. However, they do not contain all of the essential amino acids your body needs, so eat a wide variety of these foods to get the best results.
Vitamins and minerals are essential components of the human body. They enable many metabolic reactions to take place and help you get the most out of your diet.
In a biological sense, vitamins differ from other substances that are necessary for normal development and growth of higher forms of animal life in that they generally cannot be produced by the body and must be obtained in the diet or from a synthetic source.
There are 13 essential vitamins, all of which have a different job to perform in the body. Some, like vitamin A and vitamin C, are naturally occurring in foods, while others, like folic acid, must be taken in supplements.
Minerals are solid substances that have a specific crystalline structure. This makes it easier to distinguish minerals by their physical properties such as hardness, lustre, streak and cleavage (how they break).
There are two types of minerals: macrominerals and trace minerals. Macrominerals are essential for your body and include calcium, magnesium, phosphorus, sodium and potassium.
They also help your bones and teeth stay healthy. Trace minerals are necessary in small amounts and help your body make enzymes and hormones.
Most minerals are used for making products that we use every day like houses, pots and pans, electronics and batteries. Some minerals are valuable, including base metals such as copper and tin and precious metals like gold and silver. These materials are important for our economy and our daily lives.
Energy is the capacity of a system to do work, such as a jet flying across the ocean, a baby’s body growing bone cells, or a wave of light crossing a space. It comes in many forms: kinetic energy from motion, potential energy from positions, chemical energy from chemical reactions, and radiant energy from electromagnetic radiation.
The law of conservation of energy states that the total amount of energy can be changed from one form to another without reducing it, but not created or destroyed. This allows us to use electricity to power machines, heat our homes, or make food.
Energy efficiency has numerous benefits, including lower utility bills, improved air quality and energy security, and reduced emissions of greenhouse gas and other pollutants. It also helps reduce volatility in electricity prices and reduces risk for utility systems.
The immune system is a complex network of cells, organs, proteins and tissues that defend the body against bacteria, viruses and other harmful substances. It also helps remove dead and faulty cells.
Several types of cells in the immune system have specialized roles. They include white blood cells, called lymphocytes.
These cells produce antibodies, which recognize and attack germs that can cause infection.
Antibodies attach themselves to the surface of pathogens and send messages back to the rest of the immune system, telling them where to attack them.
Other immune cells, called T cells, destroy infected cells. These cells are products of hematopoietic stem cells that grow in the bone marrow.
