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.
Why is good Nutrition so important? Most people know good nutrition and physical activity can help maintain a healthy weight. However, the benefits of good nutrition go way beyond weight. Having good nutrition can help: reduce the risk of different diseases such as diabetes, heart disease, stroke, various types of cancers, and osteoporosis. Good Nutrition also reduces high blood pressure and it can lower high cholesterol. If you have good Nutrition you can improve your overall well-being, improve your ability to fight off illness, improve your ability to recover from illness or injury and more importantly increase your energy level. We all know we can always use a little extra energy through out the day. Nutrition is the sister of…
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
Plants require nutrients in order to build tissues and perform basic metabolic processes. Nutrients for plants are categorized into micronutrients (nutrients required in small amounts) and macronutirents (nutrients required in large amounts) (Rush et al. 2014). Nitrogen and Phosphorus are classified into the bracket of macronutrients and therefore the absence of those can lead to limited plant growth. Nitrogen deficiency has been repeatedly associated with inhibiting growth and leaf expansion (Khamis et al. 1990; Sinclair and Vadez 2002). The shrinking of the leaves is thought to have preceded the inhibition of photosynthesis (Paul and Driscoll 1997). An Increase in the Requirement of Nutrients Essay. This consequently affects the growth of the plant as there is not much surface area on…
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
Introduction Nutrition has a direct impact on the level of economic development in an economy. Food policies are directly related to the level of economic performance. Substantial literature indicates that nutrition directly affects the level of population health in the economy. A healthy population is more economically productive compared to a starving population. Nutritional value directs affect significantly the level of economic development in a nation. This study will mainly focus on the role food in economic performance. The study will greatly focus on the role of healthy population in the driving of an economy. An Increase in the Requirement of Nutrients Essay.Nutrition is an important element of a healthy population. Education policies are the most influential in the development if the right strategies of the population growth. The objective of the every economy is to ensure food security for its population. Every nation has the objective of developing strategic approaches that are important towards the achievement of food security (Owen, Healy, Matthews & Dunstan, 2010). In developing countries over the years have been faced with nutritional challenges. This has remained to be a major challenged and have called for international supports. Unhealthy population is expensive to maintain. Every nation spends a lot of resources in the development of curative measures in the hospitals. The food shortage in developing countries has proven as a major threat to the development of the nation (Reilly, Hull, Albert0
