The Biological Value Biological Value (BV) is a method of measuring the amount of “Protein” utilized in the body. It can be defined as “The nutritional effectiveness of the protein in a food” too.  The main Nitrogen source of the human body is Protein. So the amount of Nitrogen is used to measure the Biological Value. It can be measured by calculating the percentage of Nitrogen incorporated into the body from the amount of Nitrogen absorbed by the diet. This gives the idea of the efficiency of the food.  BV is a good measurement of protein quality too. Proteins with high Biological Value enhance better Nitrogen utilization in the body and reduce the wastage as urea through urine. It reduces the protein requirement of the body by utilizing already absorbed protein as much as possible. When the BV of a protein decreases, the amount of protein to get the maximum effect increases.   How to calculate.? BV is calculated as a percentage. The simple formula is given as follows, BV = (N r /N a

Food pyramid The nutrient imbalance is a major issue in human nutrition due to the modern lifestyle after the industrial revolution.

USDA Food pyramid was updated in 2005 as “ My Pyramid ” and in 2011 as “ My Plate ”. However, these food pyramids guide you to choose a proper diet for better nutrition.  There are 6 shelves in a food pyramid.  The bottom shelf contains fruits and vegetables. The recommendation is to have 5 to 7 servings per day. Fruits and vegetables especially contain Vitamins, Anti-oxidants, minerals with macronutr

Two main diseases can be spread by food.  Food is the most important nutrient source for the life. With the globalization of the human population, we use to consume finished food products and fast foods such as ready-to-serve beverages, canned foods, and the products which have minimum processing requirements to serve.  It’s very easy to buy a product and consume it without processing. But there are some factors to concern when buying a product from the market. You have to think, is this product safe. You can infect microbial diseases by inappropriate processing and handling of the food. Sometimes it will severely affect your health. So that’s why we have to concern about the Food-based microbial infections. Here are some microbial diseases infected by consuming unsafe foods. 1). Gastroenteritis Some others called this disease ‘Staphylococcal gastroenteritis’ due to the main pathogenic bacteria of this disease is Staphylococcus aureus when it spread through contaminated food. It is gr
