Vitamin losses can occur through chemical reactions which lead to inactive products. With regards to food chemistry, the main concern is to maximize vitamin retention by minimizing aqueous extraction (leaching) and chemical changes such as oxidation and reaction with other food constituents for a small vitamin deficiency can already cause diseases in humans (Fennema, 1996). Vitamins are mainly classified into two based on solubility: the fat soluble vitamins and the water soluble vitamins. Fat soluble vitamins are composed of Vitamins A, D, E and K while
Failure to do so results in their immune system producing antibodies which attacks the lining of their bowel causing them to have abdominal pains, constipation/diarrhoea, bloating, difficulty in gaining weight in childhood or maintaining weight in adulthood and anaemia. Because it affects the way their body can absorb nutrients it can also lead to osteoporosis and increase their risk of bowel cancer. Some foods can be bought that are labelled ‘gluten free’ but tend to be more expensive. • Irritable Bowel Syndrome (IBS) is the term used to describe a condition when on inspection of the bowel everything seems normal, but the person suffers with symptoms like abdominal pain, flatulence, bloating and constipation/diarrhoea. The person may want to keep a food diary to help discover which foods make their condition worse and avoid them in the future.
Experiment 11 Lab Assignment Answer Sheet: Chromatography of Food Dyes Name: Pre-Lab: Define the Rf value of a compound The "rf" value is the distance the compound moves relative to the distance the solvent moves. Data and Observations: Record the distance travelled by the sample and the solvent in the table below and calculate the Rf values. Table 1.

Experiment 11 Lab Assignment Answer Sheet: Chromatography of Food Dyes Name: Pre-Lab: Define the Rf value of a compound: It is the distance traveled by the compound divided by the distance traveled by the solvent front. Data and Observations: Record the distance travelled by the sample and the solvent in the table below and calculate the Rf values. Table 1.

Because electrolytes play an important role in homeostasis, the danger of dehydration and an electrolyte balance is life threatening. If the potassium or sodium levels are too high or low, it can interfere with the electrical activity within the heart causing it to have abnormal rhythms or a myocardial infarction. Low blood pressure, confusion, disorientation and renal failure can all be dangerous when there are dehydration and electrolyte imbalances.

For example, two diseases that develop from too little protein are Kwashiorkor and Marasmus, and too diseases that develop because of too much carbohydrates and lipids are Diabetes and Cardiovascular Disease. When consuming too much or too little of a macronutrient it can also result in a stunt in growth, especially in children, a insufficient amount of energy, and either weight loss or weight gain. People also tend to gain a low immune system making them more susceptible to
Answer the following questions. 1. What could have caused Myelin’s disease? Well, they may be driving at Multiple Sclerosis, for a bonus point, this is more prevalent at high lattitudes and there is a possible negative correlation with vitamin D levels. Other causative factors include lack of EFAs, whereby the body strips EFAs away from the myelin sheath of peripheral nerves to preserve the levels in the brain itself.
They tend to be high in total fat, especially saturated animal fat, which has been linked to heart disease, cancer, and perhaps even MS. The low-carb craze also restricts fruits, vegetables and whole grains. This can result in deficiencies of valuable vitamins, minerals, phytonutrients, antioxidants and fiber. All of these are important to long-term good
