- Plan a healthy diet for a thin person wishing to gain weight.
There is a link between medical conditions and nutrition. Often (though not always), your choice of foods can either aggravate or help a disorder. This chapter deals with the relationship between human nutrition, and a range of disorders affecting different areas of the human body including the skin, bladder, heart and digestive system. We shall look at some of the claims made regarding the effects of diet both in the prevention and treatment of different diseases/ conditions.
This is not a comprehensive guide, and should by no means be considered as a substitute for sound, up to date medical advice from a professional; but the information that follows, may provide some insights into the complex relationships that can exist between what you eat and your health.
Diet, medical conditions and dietary change
Before making changes to your diet to control a medical condition or before advising others to make a dietary change, it is important to understand the evidence behind this advice. This evidence is considered in greater detail in the next chapter, but as you read the next few sections you will notice that recommendations often come back to the importance of viewing everyone as an individual. It is also important to understand the difference between food allergy and other symptoms or illnesses affected or caused by different foods as the management of each type will be different.
Food allergies are caused by the immune system reacting to certain foods such as nuts, eggs and shellfish. Symptoms of food allergy include skin rashes and hives, swelling of the tongue and lips, wheezing, vomiting and difficulty breathing. Symptoms of food allergy tend to occur rapidly that is within 30 minutes of ingesting a problem food. On the other hand, food intolerance occurs when a person cannot absorb or digest nutrients properly and symptoms tend to develop more slowly (up to 48 hours after eating a problem food). This can make it difficult to identify which food is causing the problem; examples of food intolerance include lactose intolerance and celiac disease. Although there are tests available to diagnose these two forms of food intolerance, most food intolerances are found through trial and error. To determine which foods cause a problem patients are usually asked to keep a food diary to record what they eat and when they get symptoms, a doctor or dietitian may then look at the food diary to identify any possible food triggers. Another way to identify problem foods is through an elimination diet. This involves completely eliminating any suspect foods from the diet until the patient is symptom-free and then reintroducing foods, one at a time to help pinpoint which foods cause symptoms. A typical elimination diet includes chicken, turkey or lamb, rice, cooked vegetables, apricots, apples, pears, peaches and bottled water.
