The thyroid gland, situated at the base of the throat, controls our rate of metabolism. In hyperthyroidism or overactive thyroid, symptoms such as over-activity, loss of weight and nervousness are common; in hypo¬thyroidism or underactive thyroid, the symptoms are lack of energy, becoming overweight and goitre, in which the throat region swells. Over-stimulation of the endocrine system through living off stress and stimulants, and oestrogen dominance, are common causes of an underactive thyroid later in life. This can also be caused by a lack of iodine, although this is rare, and taking iodine in kelp is advised to help the condition. Since the thyroid gland is controlled by the pituitary and adrenal glands, the nutrients involved in hormone production and regulation for all three glands are particularly important. These are vitamins C and B complex (especially B3 and B5), manganese and zinc. Selenium also appears to have a role to play in thyroid health, as does the amino acid tyrosine from which thyroxine is made. Often, a low dose of thyroxine is required to correct this condition.
Tinnitus is a condition said to affect as many as 4 million people in Britain. It has many causes and contributors. Many prescribed medications list it as a side effect, for example. It can also be triggered by loud noise – either a single blast or exposure over a long period of time. It is likely to be often caused by inflammation in the ears, or constriction causing restricted blood flow. Eating a diet low in saturated fat and high in essential fats can help. Having diabetes or a blood sugar problem can be a contributing factor. This is probably because blood sugar lows increase adrenalin which constricts blood vessels. Infection and allergy are two other contributors that could cause inflammation in the ear. Therefore I recommend you check out your food allergies and include 2 grams of vitamin C in your daily supplement programme. One of the most common causes of inflammation is a hidden food allergy. Although milk and wheat are common foods, and hence worth avoiding for a fortnight to see if that makes a difference, it can be anything. The only way to find out is to have an IgG food intolerance blood test. This is the main antibody causing food reactions. (There is another type of antibody, IgE, that also causes allergic reactions but most IgE allergies will show up on an IgG test.)
