The macular lies in the centre layer of the eyes so while damage due to environmental trauma such as violence or infection is rare it is more likely to be due to aging and has more severe impact which could range from mild discomfort to complete blindness. Symptoms include difficulty with driving, making out printed words or faces. The failure of some elderly in recognizing faces is not always due to memory but rather their inability to see the face well enough for them to recognize the individual. The macular has a natural protection against degeneration in the form of the xantophyll carotenoids present in the cone cells of the fovea, these protect against UV and blue light by thier share color. There is a small amount naturally present in the body but the bulk of the requirement is supplied in the diet.
Other than old age other factors relating to macular degeneration include gender (more prevalent in women), heredity, ethinicity (more prevalent in whites), nutrition, level of sun exposure, smoking habits and pre-existing conditions such as hypertension. Age related macular degeneration can occur in individuals as early as 40 years old and usually is chronic. Macular degeneration can occur as a result of changes in blood flow to the eye which occurs with age. However it could also occur as a result of structural and biochemical changes to the eye in the process of aging and other age related factors. These includes accumulation of dusen and debris which are produced as by products of metabolic processes.
Macular degeneration can be avoided by including sufficient amount of carotenoids in the diet. Foods such as dark leafy green vegetables such as spinach, plenty of fish, fruits and nuts. Supplements which can also promote good eye sight include multivitamins, multiminerals and fish oil supplements. avoid high cholesterol and high glycemic index foods. Supplements containing different formulations of beta carotenoids, vitamin C, vitamin A, zinc and copper have been shown to be effective in management of macular degeneration. Furthermore necessary precautions such as use of protective eye wear when out in the sun and regular exercise is a significant preventive measure against age related macular disorder. Regular eye examinations are necessary so as to detect macular degeneration early. Useful links http://lifespanmeds.com/fishoil.htm
The reason behind effectiveness of therapeutic fasting for bronchial asthma is stimulation of the activity of the immune system. In fact, there are two main causes contributing to the development of asthma; the first one is endobronchitis (usually an immune caused inflammation on the mucosa of the bronchi), which in turn leads to the second factor – hypersensitivity (allergic reactions). The trigger of the asthma stroke could be either chemical, for instance a contact with a particular chemical agent, or physical exercise, and the last, but not the least - stress.
Short term fasts stimulate adrenal glands to secrete high doses of corticosteroid hormones, which supress allergic inflammation in the bronchi and thus reduce the hyperproduction of the mucus and lead to dilatation of the bronchi. This also results in the activation of the reparative processes, release of the bronchi from the pathogenic microflora, therefore resulting in the improvement of the airways conduction.

Although there has been a huge step forward in the development of pain relieving and anti-inflammatory agents for RA, patients lately have become more interested in the alternative means of treatment. Therefore the demand supported by the efficiency of traditional healing practices of different countries, especially those of East and South East Asia encourage scientists to find a new way of treating RA.
So far the scientific evidences suggest that both vegetarian individually adjusted diet and short term intermittent fasting have positive effects both on clinical and laboratory signs of RA patients. The former are presented by reduction of pain, duration of morning stiffness, the number of swollen joints, with the increase in the mobility and grip strength. The laboratory changes included erythrocyte sedimentation rate, C-reactive protein, white blood cell count, activity of lymphocytes and some other (Controlled trial of fasting and one-year vegetarian diet in rheumatoid arthritis, by the Department of General Practice, University of Oslo, Norway). In the majority of studies the patients were administered with a very low calorie diet or fasting which was followed by strict vegetarian or lactovegetarian diet. Moreover, in the follow up research conducted by M. Haugen, D. Fraser and O. Forre there have been significant changes of the subjective variables, when the patients were returned to their usual diet: “Of the 10 responders examined in the follow-up study, eight reported an increase in disease symptoms after intake of different kinds of meat, and six after intake of coffee, sweets and refined sugar”.
Obviously, the condition could be prevented by changing lifestyle and adjusting eating habits. Early century specialists used fasting modality as a treatment option for onset of type 2 diabetes. Numerous recent researches have reported significant decrease of glucose, insulin, triglyceride and lipoprotein levels in obese patients who underwent 16 week very low calorie diet program ( the study “Prolonged Caloric Restriction in Obese Patients With Type 2 Diabetes Mellitus Decreases Plasma CETP and Increases Apolipoprotein AI Levels Without Improving the Cholesterol Efflux Properties of HDL”). Overall, the glycemic control in obese patients significantly improves in response to prolonged and intermittent caloric restriction.
However, for the majority of the patients it appears quite demanding to follow dietary and lifestyle recommendations on their own, because of poor self-control, short lasting self-motivation and low awareness about the future results, which are often overestimated beforehand. Therefore the treatment has to be either performed in the medical facility or closely supervised and controlled by a physician. This option will also help you to escape plausible side effects and complications on your way.

In various religions fasting is often performed in one form or another. Although it is carried out for spiritual purposes, there are some scientific evidences that abstention from food could alter the health of an individual. There are three main religious fasts: Islamic Ramadan, Greek Orthodox fasts and the Daniel fast of the Christians. The health impact of various religious fasting practices recently became a subject for numerous researches and studies.
Despite that the investigations were preliminary and no yet well-organized (in some cases the subjects were not selected properly and a number of contributing health and lifestyle factors were neglected), their results were already quite promising. The main features subjected to analysis were BMI changes, hematological signs, biochemical values and blood pressure level.
The number of studies of Ramadan fasting effects presented quite heterogeneous findings regarding both dietary intake and health related values due to mentioned inaccuracies. However, in the hospital based studies the results showed statically significant decrease of systolic and diastolic blood pressure in response to short term water-only fasting. So, in “Acute effects of short-term fasting on blood pressure, circulating noradrenaline and efferent sympathetic nerve activity” eleven moderately obese women with borderline hypertension fasted for 48 hours. Significant decreases in body weight from 88.4 +/- 2.5 kg to 86.4 +/- 2.5 kg were achieved by the end of program. Systolic blood pressure was reduced from 158 +/- 3 mmHg to 146 +/- 5 mmHg (p less than 0.001) and diastolic BP from 96 +/- 3 mmHg to 89 +/- 3 mmHg (p less than 0.01).
Similarly, the results of “Medically supervised water-only fasting in the treatment of hypertension” are suggestive that medically supervised water-only fasting appears to be a safe and effective means of normalizing blood pressure and may assist in motivating health-promoting diet and lifestyle changes. Almost 90% of the subjects achieved blood pressure less than 140/90 mm Hg by the end of the treatment program. All of the subjects who were taking antihypertensive medication at entry (6.3% of the total sample) successfully discontinued the use of medication.
In general, the cause of chronic fatigue syndrome is unknown, although there are many theories — ranging from viral infections to psychological stress. Some experts believe chronic fatigue syndrome might be triggered by a combination of factors. As the origination of the disease is still under investigation, there are no specific medications or procedures which promise total and complete recovering. Although the treatment options adopted nowadays by the specialists are mainly focused on symptoms relief, the efficiency of each method or their combination is highly individual. In the majority of medical institutions the patients are offered various psychological counseling methodologies, in particular cognitive behaviroral therapy (CBT). Graded exercises – another option, where the types of exercises are to be suggested by the physical therapist on individual basis depending on your particular health condition.
According to the researchers, fasting can be beneficial for treating some allergic and inflammatory conditions, because the process of ketosis decreases the availability of the fatty acid, arachidonic acid, which tends to increase inflammation. Ketosis is the process by which the body begins to use fat instead of glucose as a fuel source. A 1991 study published in "Lancet" by Kjeldsen-Kragh, showed that a four-week juice fast, followed by a year-long adherence to a vegetarian diet, resulted in decreased joint pain, stiffness, inflammation and need of medication in patients with rheumatoid arthritis. This fact makes it plausible that intermittent fasting and calorie restriction is one of the methods which could be used as a cure for other inflammatory conditions, and CFS in particular, in those cases, when infection and inflammation are considered to be the main background cause.

Heilbron et al examined the effect of ADF on CVD risk. When human subjects fasted on alternate days for a short period (3 weeks), circulating concentrations of HDL cholesterol increased, whereas triacylglycerol concentrations decreased. It is possible that these effects resulted from the decreases in body weight (2.5%) and fat mass (4.0%) observed in these subjects, who were unable to consume sufficient calories on the feast day to maintain an isocaloric state. It is interesting that the shifts in lipid concentrations were shown to be sex specific: i.e., only the women had an increase in HDL-cholesterol concentrations, and only the men had a decrease in triacylglycerol concentrations. There is no clear explanation for these sex-based differences. The effect of ADF on blood pressure was also examined in this study. After 3 weeks of intervention, neither systolic nor diastolic blood pressured changed in either the male or female subjects. This study included only normotensive persons, however.
The last, but not the least, the principal investigator in this study noted an apparent lower rate of cardiovascular aging, with arteriosclerosis progress indicators particularly slowed.
