Or they say that we should replaced refined grains with whole grains due to higher incidence of diet related illnesses such as diabetes, obesity and heart diseases. But have you ever wondered as why is that so? Why are refined grains bad for us and how they can affect our health?

Eating healthy and nutritious foods is very important for good health. Despite being consumed widely, the health effects of grains are still to be known clearly as some people believe they are healthy whereas some believe them to be harmful for us. So, a clear understanding is very important and this article will provide you an insight into refined grains and how they are different from the whole grains and what effects they have on our health?

Mixing and Homogenization

Mixing is a unit operation in which uniform mixture is obtained from two or more compounds by dispersing one within another. When two or more materials are mixed, the goal of mixing is to obtain homogeneous final mixture. Homogeneity is the quality of being homogeneous. A perfect homogeneous sample indicates the state of complete mixing. Mixing has no preservative effect on food. It is a processing aid to alter eating quality of food and to achieve different functional and sensory quality of food. In some food adequate mixing is necessary to ensure that the proportion of each component in the sample complies with legislative standards. Read more

Extraction Techniques

Depending upon need and quantities of material to be handled, different extraction techniques are used in food industries. Some popular extraction techniques are
1. Single stage batch extraction
2. Multi stage cross flow extraction
3. Multi stage counter current extraction

1. Single stage batch extraction:
It is a batch extractor in which the solids are brought in contact with adequate quantity of solvent so as to leach out the solute from solid into the solvent. The process can be accompanied with heating or stirring as the process demands. When the extraction process reaches equilibrium, the solution is decanted and excess solvent from the solution is removed to obtain pure solute. Example; brewing tea or coffee, extraction of oleoresins. Read more

Non Thermal Preservation of Food – Oscillating Magnetic Field (OMF)

Oscillating magnetic field (OMF) is generated with electromagnet of alternating current. The intensity varies periodically according to frequency and type of wave in the magnet. OMF is applied in the form of constant amplitude or decaying amplitude sinusoidal wave. The magnetic field may be homogenous or heterogeneous. In homogenous field, field intensity (B) is uniform in the area enclosed by the magnetic field coil. In heterogeneous field, field intensity (B) is non – uniform with the intensities decreasing as distances from the center of the coil increases. Read more

To develop their optimal potential it is vital that children are provided with nutritionally sound diet. Diet and exercise pattern during childhood and adolescence may spell the difference between health and risk of disease in later years. Different stages of life cycle dictates different nutrients needs.
Important nutritional considerations in first stage of life:
In first 12 months of life a baby will triple its weight and increase its length 50 %. These gain in weight and height are the primary indices of nutritional status and their accurate measure at regular intervals are compared with standard growth charts. These measurements are important tools for monitoring a child’s progress particularly during the first 6 to 12 months of life. Read more

Healthy eating and healthful way of life are important to how we look, feel and how much we enjoy life. The right lifestyle decisions with good food and good regular exercise can help us make the most of what life has to offer. Making smart food choices early in life and through adulthood can also help reduce risk of obesity, hypertension, diabetes, certain cancers and osteoporosis. Following are the healthy eating habits for adults.
1. Enjoy wide variety of food: This concept it is the most consistent health message in dietary recommendations around the world. We need more than 40 different nutrients for good health and no single food can supply them all. That is why consumption of a wide variety of foods (including fruits, vegetables, cereal grains, meat, fish, poultry, dairy products, fats and oil) is necessary for good health and any food can be enjoyed as part of a healthy diet. Some studies have linked dietary variety with longevity. In any event, choosing a variety of foods adds to the enjoyment of meals and snacks. Read more
