According to the 2015 Academy of Nutrition and Dietetics survey of health professionals with experience in Central America, there is a lack of basic knowledge of biology and physiology in developing regions of the region. Starting with a discussion of basic health concepts and then explaining how nutrition affects our bodies is a good strategy.

Explaining Organ Functions

  • Lungs: provide oxygen to blood
  • Heart: circulates blood throughout the body
  • Stomach: helps digest food
  • Intestines: absorb nutrients from food
  • Liver: removes toxins from blood and processes nutrients from food
  • Kidneys: filter blood of waste and extra fluid
  • Explaining Nutrition.

It is food that influences the body’s health. It provides important survival nutrients to help the body work and stay healthy. Nutrition is necessary. Food is composed of macronutrients, including protein, carbohydrates and fat, which not only provide the body with energy and calories, but also contribute to health.

Also, food supplies micronutrients (vitamins and minerals) and plant chemicals to ensure that the body is operating optimally. Food does not provide calories but has a variety of critical functions. You can opt Biomedical Research Journal for more information.

Explaining Macronutrients: Protein, Carbohydrate and Fat

Protein: found in traditional Central American cooking, in beef, pork, chicken, game and wild meats, fish and seafood, eggs, soybeans and other legumes, protein gives amino acids to the body.

Amino acids are the building blocks of proteins essential for body tissue growth, development and repair. Protein provides muscle and bone structure, repairs tissue when damaged and helps immune cells fight infection and inflammation.

Carbohydrates: Carbohydrate’s main role is to provide energy and fuel to the body, just as cars are fueled by petrol. Food including corn, cabbages, peas, plantains, rice, tortilla, potatoes, and other root vegetables like yucca, pasta, and fruit provide energy-providing sugars or starches.

Energy allows the body to work every day as simply as to walk, talk, and ride, and move heavy objects as complex. Fuel is needed for growth, which makes enough fuel particularly important for children and pregnant women growing. The body needs calories even at rest, so that it can serve vital functions including maintaining body temperature, breathing and food digesting.

Fat: Dietary fat found in oils, cocoa, nuts, milk, cheese, food, poultry, and fish provides a cell-and cushion-like structure for damage prevention. Fatty oils, including vitamin A, a nutrient vital for the healthy eyes and the lungen, are necessary for absorbing fat-soluble vitamins.

Explaining Micronutrients: Vitamins and Minerals

Vitamins and minerals constitute food components that help promote overall health and play important roles in neurological and cell metabolism.

Vitamins help to generate energy, healing of wounds, development of bones, immunity and protection of the eye and body.

Minerals help preserve cardiovascular health and build a skeleton structure.

The body has plenty of nutrients to use when using a balanced diet including fruit, vegetables, milk, protein foods and whole or enriched grains. The effectiveness of nutrient education can be improved with some examples of specific micronutrient functions: calcium and magnesium help muscles and blood vessels to relax, avoid cramps and high blood pressure.

Vitamin C helps heal wounds and removes germs in the skin.

Iron allows the whole body to bear blood oxygen and avoids anemia.

Explanation as a building block of the theory of nutrients.

The building blocks include protein for the growth in the utero of babies, for growth in young people and adolescents, and for the repair in non growing adults of damaged skin, blood and other parts of the body.

Many parts of the body, including blood and hair, are constantly recycled, so that even adults frequently build new parts of the body. The building block for bones is also calcium. Iron is a blood building block. The body constantly needs more iron and protecting blood because blood cells last only a couple of months. Opt Nutritional Science Journal.

A device that is used for measuring the pressure in a gas or liquid is known as a pressure gauge. These pressure gauges are commonly used in every part of the globe in factories and industries since they come at an affordable price.

These are pressure sensors that are used readily in industrial equipment. Since these are installed on a huge number, their maintenance becomes quite hard. Because of this reason, it’s not an uncommon scenario to find a lot of gauges that don’t work properly.

This can turn out into a bad situation due to having a failed pressure gauge, the safety of these instruments might be compromised, which is why it’s important to have the right one like WIKA pressure gauge. If you have the right pressure gauge, installing only a few instead of a lot of them is a better option for safety and accuracy as well.

Let’s have a look on the steps to choose the right pressure gauge:


If you are using a mechanical gauge then you can measure the accuracy by full-scale range calculated in percentage. The best mechanical gauges are manufactured by WIKA that are reliable and long-lasting for any industrial purpose.


There are multiple sizes of pressure gauge dials that have a diameter that ranges from 11⁄2˝ to 16˝. For the most part, intelligibility necessities, space constraints and required gauge precision decide dial size. For 0.25 to 0.5% accuracy, the requirement of dial sizes are generally large. 


Natural contemplations incorporate surrounding temperature, air-borne particulate, buildup, dampness, water and synthetic substances, all of which can influence gauge execution. 

Encompassing temperature may influence the precision and trustworthiness of the gauge. Encompassing conditions may necessitate that the gauge is segregated from temperature boundaries. At the point when required, the gauge ought to be detached from temperature limits with an adaptable line gathering. 

At the point when surrounding conditions are destructive, contain an enormous number of particulate or if the gauge will be presented to a wet or moist condition like mugginess, wash-downs or downpour, determine a gauge that is weatherproof/hermetically fixed or fluid filled. 


The wetted pieces that are present in the pressure gauge, the cylindrical tube and its attachment must be compatible with procedure media in order for it to work properly. If not perfect with the wetted pieces of the gauge, consumption will happen. Erosion of gauge wetted parts will, in the end, cause gauge disappointment and perhaps wellbeing issues. At the point when the gauge wetted parts are not good with the procedure media, a stomach ought to be considered. 

5. Size Of The Connection

Gauges are accessible with an assortment of different connections that includes NPT, DIN, JIS, BSP and SAE. Procedure pressure gauges with 41⁄2˝ dial sizes or bigger are frequently provided with a 1⁄2˝ NPT connection that will support the gauge the best way. 

Elements to think about when choosing a pressure gauge association to incorporate procedure pressures, gauge estimate and weight, space impediments, spill uprightness, and past experience.

6. Range of Pressure

ASME B40.100 prescribes that typical working pressure be kept to 25%-75% of the scale. On the off chance that throb is available simultaneously, greatest working gauge pressure ought not to surpass half of the full-scale run.  

To find the right pressure gauge,  consider the process of the gauge, how much range it provides you, in what environment it needs to be used, proper accuracy of the gauge, the dial size and the requirements for mounting of the gauge.
