An Increase in the Requirement of Nutrients Essay
Proteins are generally required for growth and maintenance of body weight in humans and they are made up of a simple chemical substance called amino acids, which in turn can be classified as essential and non-essential amino acids. Essential amino acids are those that can only be derived from the diet and non-essential are those that can be synthesized in the body. The essential amino acid contents differ from one protein to another. Hence the nutritional value of dietary foods proteins depends on their essential amino acid content. All protein-rich foods like milk, eggs, cereals, fish, etc may be rich in only certain essential amino acids. Hence in order to gain all the essential amino acids, a balanced diet of the protein foods is needed. An Increase in the Requirement of Nutrients Essay. In the case of vegetarians, balanced use of all the cereals is required to gain all the essential amino acids. If any cereal is eliminated in particular it might result in a deficient supply of the essential amino acids present in it, thereby leading to protein deficiency.

2. a. i) The brain requires a readily available form of sugar and starch would provide the readily required glucose. The mean protein requirement is about 70 g/ day for an adult. The amount of cellulosic fibers required is about 40 g. these are indigestible polysaccharides which do not actually supple calories but they help by delaying the passage of food through the GI tract, stimulate intestinal peristalsis and help prevent constipation. The saturated fat consumption could be lesser when compared to the unsaturated fat content as the dietary fat intake should ideally not be more than 80 g/day. Calcium intake is ideal.
ii) Fat content in the diet should generally be less especially in the case of sedentary and obese people. An increase in fat content, especially saturated fat, may lead to an increase in serum cholesterol levels and thereby fat deposition in arteries resulting in atherosclerotic conditions. The type of fat taken in the diet should also be considered. An Increase in the Requirement of Nutrients Essay.
They all must be in balance for the body to function properly. There are also five major food groups. The groups are: fats and oils, fruits and vegetables, dairy products, grains, and meats. The world of foods and nutrition has changed a lot over the years. Back then it use to be whole milk, red meat and eggs. Now many doctors are encouraging leafy green vegetables, fruits, and whole grains. An Increase in the Requirement of Nutrients Essay. The old way has gotten many people into health problems. Heart disease and Cancer have become a huge problem. That’s why proper nutrition is so important! Some people have some common knowledge on what is good and what is bad for the human body to consume. Fruits, vegetables, nuts, and grains are some common items people think of when they think of healthy foods. It is not enough just to know what foods are good for your body, it is also important to understand why certain foods are good for you and what they do to help the body function. Food is anything we consume, whether it is for taste or for nutritional value. The nutritional value of a food is the value the food gives to the body to function. Many children are struggling with their weight. Its baffling anymore to turn on a television
The seeds grown under the complete treatment, with all nutrients present, will have the greatest amount of growth and will be denser while the phosphorus and nitrogen deficient soils will result in thin, short and fewer leaves due to growth inhibition and decrease in metabolic processes. However if the plants are indifferent to the three treatments then all the three containers will witness equal plant growth suggesting that the absence of the macronutrients does not have a significant impact on plant growth.
As observed from Figure 1, the phosphorous deficient plant had the greatest root length. Although this is not an expected observation, a study conducted on the effects of phosphorous supply on tomatoes suggests that root morphological traits are influenced by low Pi (phosphate ions) conditions which leads to increased root lengths (Basirat et al. 2009). Low Pi supply also enhances the formation of long root hairs (Bremer and Schenk, 2009) so that the absorption of the phosphate ions can increase and the plant can further dig into the soil to find free flowing phosphate ions. An Increase in the Requirement of Nutrients Essay. These techniques are a method to increase the roots adaptations in deficient conditions (Marschner et al., 2010). According to table 1, the comparison between control and nitrogen deficient treatment for shoot length rejects the null hypothesis which
