Essays on Vitamin A

Human nutrition is associated with good health and well-being. Humans derive nutrients from food products such as fruits, vegetables, milk, and animal-based products. Nutrients should be taken in adequate quantities for proper functioning of the body. Diet provides vitamins, minerals, and all other vital components required for healthy living. Diet is one part of a healthy body while physical activity enhances growth, development, and stability to the body. People who have low nutrient intake are vulnerable to diseases and illnesses. Poor nutrition has also been associated with impaired physical and mental development (Kau, et al. 2011). Nutrition is the ...

According to the Institute of Medicine in the United States of America, the following are the guidelines for weight gain in women of different body mass indeces – Underweight women, i.e. those with a BMI less than 18.5 are required to gain 28-40 pounds, normal weight women, i.e. having a BMI of 18.5 to 24.9 are required to gain 25-35 pounds and overweight women, i.e. those with a BMI above 25 to 29.9 are required to gain 15-25 pounds (“Assessing Your Weight”, n.d.). For pregnant women, the required daily allowance (RDA) of the two macronutrients Calcium and Choline should be ...

Introduction

Until recently, genetic foods have become popular for their ability to address many production and quality issues faced by natural/organic farming methods. Genetically modified crops are those whose genetic makeup has been improved to enhance the level of nutrients, resistance to diseases, increase yields, adaptability to climatic factors, and reduce the time of production (Ronald & Adamchak, 2008). It is different from the conventional breeding because genetic modification allows introduction of genes from any organism (animal and plants) in altering crops whereas breeding allows transfer of genes across related species only. On the other hand, organic farming is a natural ...

Do blueberries and strawberries have similar levels of anthocyanins? How could you find out?

No, blueberries and strawberries have different levels of anthocyanins because anthocyanins are responsible for the colors associated with the fruits. (Berries and the Brain, n.d.) Since they have different colors, they have different levels of anthocyanins. Levels of anthocyanins in different fruits can be determined by chromatography or by using a spectrophotometer. The easiest way would be to separate the anthocyanins from other pigments in the fruits using different solvents, and then chromatographing the extracts. Finally, the amount and wavelength of light they absorb can be determined using a calorimeter which would help measure a number of anthocyanins in ...

Human development patterns allow us in making generalizations concerning various stages as the infancy phase, childhood phase, adolescence, and finally the adulthood stage. For the first year following the birth, a baby is referred to as an infant. The childhood stage begins in the second year after birth and stretches until adolescence. Childhood stage is often divided into early childhood and middle childhood. Early childhood includes the pre-school years whereas middle childhood stage includes elementary school years, through the fifth or sixth grade. The adolescence stage is the second last stage of human development before adulthood. This stage is ...

Abstract

Nutrition is the intake of food which is necessary for survival. A healthy nutritional diet is essential for a healthy body and mind. A balanced diet helps in growth and development, strengthening the immune system, executing the all-important chemical and hormonal activities as well as cell reproduction. Food is further categorized into types and components that play a significant role in processing the biological mechanism at a very minute level. There is six main type of food that includes grain, milk products, Meat, fruits, vegetables, and oils. Water is the most important part of ...

Introduction

The issue of genetic modification of animals and plants have been heatedly debated upon in both public and scientific discourses. As technologies become more advance, people begin to largely alter, rather than depend, on their environment. On the one hand, people’s lives become easier and mass production and consumption is possible. One the other hand, the alteration of environment disrupts ecological processes that may endanger human, animal and plant life, and the issue of scarcity of resources are increasing becoming visible as humans use more and more raw materials. Despite the perceive benefits of GMO, more researches must ...

Vitamins and chronic diseases

Fat-soluble vitamins include A, D, K, and E whereas water-soluble vitamins are ascorbic acid, thiamin, riboflavin, niacin, pyridoxine, folacin, vitamin B12, biotin and pantothenic acid. They are referred to as fat-soluble because they can only dissolve in organic solvents and as a result, their transport within the body is similar to the fats. The water-soluble vitamins, on the other hand, dissolve in ionic solvents like water. The intake of both fat and water soluble vitamins have been said to impact the development of chronic diseases like cancer, diabetes, heart disease and even stroke. Some relationships between the vitamins and ...

Abstract

In the current health scenario, the old adage ‘prevention is better than cure’ is outdated ("A New Vision of Wellness", 2011). Health costs are increasing day by day, but diseases have become more prevalent than before. Incidences of impaired mental health are on the rise. Isn’t it high time that we stop and take a look at the current medical scenario? People are suffering from chronic diseases like asthma, depression, diabetes, heart disease, pain, and even attention and learning problems. Moreover, the pharmaceutical companies are always introducing newer and better medicines and expensive ones too, but still, there ...

Dietary assessment is important since it helps in detecting the risk of nutrition problems. Additionally, nutrition assessment helps in determining the nutrition status of a person. Poor nutrition is associated with many health concerns. Indeed, individuals who have inadequate intake of nutrients are likely to develop many health-related problems. Poor nutrition can also adversely affect the effectiveness of medications. Therefore, a proper diet is an integral part of medical interventions. This paper provides findings of the dietary assessment conducted using the food frequency questionnaire. The assessment showed that the client’s diet does not meet all the RDA recommendations. ...
