Iodine: Have You Overlooked This Essential Micronutrient?

March 27, 2014 happyholistichealth 2 Comments

One essential trace element that not many people ever think about is iodine. It is essential to many of the functions of your body. But many Australians are deficient in iodine. And not just Australians, as in fact it is thought that up to 40% of the world population is getting insufficient iodine.

Iodine can be found throughout the organs of your body. Highest concentrations occur in the thyroid gland and it is also found in the ovaries, skin, saliva, breasts and gastric glands although it can be detected in every organ and tissue.

In the thyroid gland, iodine along with the minerals zinc and selenium is essential for the production of thyroid hormones, particularly thyroxin. These thyroid hormones directly control the body’s metabolic processes, which in turn have significant influence on many of the body’s organs and processes including heart rate and blood pressure.

When iodine levels are too low the thyroid is unable to produce sufficient levels of hormones and you start to experience a range of symptoms such as lethargy, sleepiness, depression, intolerance to cold, dry skin, slow digestion, goiter, weight gain and slower mental faculties.

Health Benefits

Iodine has so many health benefits and iodine deficiency has been linked to goiter, hypothyroidism, obesity, cognitive impairment, heart disease, psychiatric disorders and cancer. It also causes impaired mental and physical development.

Iodine helps prevent the storage of excess calories as fat, assists in the removal of toxins and aids in the utilization of other minerals. It strengthens the immune system and maintains healthy tissues throughout the body.

Addressing iodine deficiencies has been found to very effective in the treatment of goiter, ovarian cysts, uterine fibroids, fibrocystic breasts, hypertension, obesity and diabetes.

Food Sources Of Iodine

As it became apparent that more and more people were suffering from an iodine deficiency, an attempt to address the growing problem was made by fortifying a certain range of foods with iodine, including basics like bread and milk. Since 2009 iodine has been added to bread, and prepackaged bread required to list iodised salt as an ingredient.

Although iodine it is a fairly rare mineral it is present in a number of foods. The best sources are marine plants such as spirulina, seaweed like kelp, nori, dulse or kombu and shellfish. Make sure that any produce from the sea is harvested from uncominated waters.

While iodine is found in abundance in the sea it is not as prevalent in soil, and due to the toll that modern farming practices have taken means that most soils contain extremely low levels of iodine, along with many other minerals vital to good health. This transfers to low levels of iodine in crop foods. Unfortunately, the amount of iodine found in foods is completely dependent on the amount there is in the soil

Baked potatoes are a great source of iodine. Some other vegetarian sources are eggs, milk, garlic, lima beans, swiss chard, sesame seeds, soybeans, turnip greens and spinach.

Prior to the 1970’s milk was one of the foods that contributed most iodine to the diet but since the 1990’s the amount present in milk has dropped to about half due to changes in dairy processing practices.

Iodised salt was one food that provided many with daily iodine. But with firstly the awareness of the relationship between high salt intake and hypertension, and now a growing awareness of the problems with all highly processed foods including salt, consumption of this source of iodine has dropped off significantly.

If you are trying to avoid conventional salt you could replace it with Himalayan Salt in moderation, which is a viable alternative. Half a gram contains 250 micrograms, 150% of what the body requires each day.

To combat iodine deficiency dried seaweed is the food to head for. Just seven grams supplies 4,500 micrograms of iodine – 3000% of your daily requirement. Rather than having this much at one meal eat smaller quantities more frequently to maintain a regular supply.

Don’t forget that you may eat substantially less than 100grams of some of these foods so you need to consider just how much iodine there actually is in the food you are eating.

How Inadequate Iodine Intake Affects You

Perhaps the most obvious, but least dangerous manifestation of iodine deficiency is goiter, a swelling of the thyroid gland which manifests as a swelling in the neck and around the larynx. Treating goiter with iodine during the first five years usually ensures that the thyroid does not suffer permanent damage.

It is well known that micronutrient deficiencies are known to affect the development of intelligence and iodine deficiency can certainly be included as one. Inadequate iodine has a significant effect on cognitive function, affecting memory.

Although iodine is recognized as a major requirement for thyroid health, it also plays other important functions including boosting the immune system, by increasing antioxidant activity.

Iodine is widely used to treat fibrocystic breast disease. It has been shown in studies to shrink caner cells when injected directly into the cells. It is essential in the prevention of thyroid cancer. It assists with flushing out chemical toxins including fluoride, lead and mercury.

Deficiency in children not only causes lower IQ but also creates issues with learning and concentration. It can be an ongoing issue when intake is too low.

Iodine is Required for Reproductive Health

Iodine offers lots of assistance to the reproductive organs. Sufficient levels are crucial to ensure fertility initially, as well as during pregnancy to prevent miscarriage or stillbirth, and to prevent neorologic and cognitive conditions in the baby. Severe deficiency during the pregnancy can lead to the following problems:

Miscarriage during the first trimester, or stillbirth
Gestational hytertension
Birth deformities
Neurological defects in the baby causing irreversible brain damage – cretinism, intellectual difficulties, hearing loss and speech difficulties, short stature, deaf mutism, dwarfism

Iodine passes into the breast milk in large quantities and nursing mothers need to maintain their intake of iodine in order to prevent iodine deficiency themselves.

What Can Cause Iodine Deficiency?

There are a number of factors that can lead to iodine deficiency including:

Low amounts of iodine in the diet

Selenium deficiency
Pregnancy
Radiation exposure
Smoking tobacco
Alcohol
Oral contraceptives

Some Deficiency Clues

Here are some symptoms that could provide the clue that you are not getting enough iodine. If you suffer from these symptoms consult your health care practitioner:

Dry mouth
Dry skin, reduced sweating
Hair loss
Reduced alertness, poor perception, lowered IQ
Fibromyalgia, pain, fibrosis
Scar tissue, nodules
Frustration
Depression
Abnormal weight gain
Reduced fertility
Constipation
Fatigue

A word of caution if you live in an area where fluoride is added to the water supply. There have been studies which question the validity of fluoridation of drinking water because there is a link between excess fluoride ingestion and thyroid disease. The incidence increased where water was fluoridated as the fluoride inhibits the action of the iodine. It may be something worth thinking about if this applies to you.

Iodine supplementation is one place where you can get too much of a good thing. There are potential risks to taking too much iodine. Doses over 2,000mg a day are dangerous especially if you have kidney ailments. Too much can easily lead to subclinical hypothyroidism – ironic when you consider that hypothyroidism is often linked to iodine deficiency. Sourcing iodine from foods may be preferable to taking supplements.

Iodine is certainly one supplement where you need to make sure you achieve a healthy balance.

Could It Be Your Thyroid Causing Your Poor Health?

June 13, 2013 happyholistichealth 2 Comments

For many people an underactive thyroid slows them down and leads to a host of other unpleasant symptoms. Most of those people are never diagnosed with the disorder. Many are never treated. Many fail to make the changes in their diet and lifestyle that can really help ease their symptoms. Most go on living their life in a debilitated state.

The Thyroid is a butterfly shaped gland in the middle of the front of your throat. It’s purpose is to release hormones that help in the regulation of many body functions – metabolism, heart rate, maintaining your core temperature, healthy skin, your weight, fertility and more. It slows you down or revs you up to make you more energetic. It also activates your immune system. It plays a part in most of the body’s physiological processes, so when it is out of balance, so are you. In fact every cell in your body has receptors for thyroid hormones.

Sometimes the thyroid does not work as it should and, depending on whether it is pumping out too many hormones or too few, it becomes under- or over-active, what is known as either Hyperthyroidism (too many thyroid hormones in the blood) or Hypothyroidism (too few).

Thyroid conditions can be quite common and it is estimated that about 20-25% of the female population may suffer from hypothyroidism. An estimated 30% more of people over the age of 35 may suffer from “subclinical” hypothyroidism, where they either have no obvious symptoms, or their test results are within the ‘normal’ range but they have mild symptoms of low thyroid function.

Many people live with the symptoms of low thyroid function often for years, where their thyroid gland works sluggishly without them even realizing it. With too few thyroid hormones in the blood the body processes start slowing down, and so do they.

However, there are some telltale signs to look out for. Here are some of them, although there are many more:

Fluid retention or swelling in the legs, feet, arms or face
Cold hands or feet, poor circulation and intolerance of cold
Dry skin, acne and eczema
Lethargy, fatigue, poor stamina and sleeepiness
Forgetfulness, slow cognitive function, brain fog
Depression
Constipation, indigestion
Weight gain, or difficulty losing weight
Poor brittle, slow-growing nails and hair, hair loss
Heavy periods, irregular cycle, PMS
Infertility, low libido
Insomnia
Muscle and joint aches and pains
Food cravings, food intolerances, hypoglycaemia
High cholesterol/ triglycerides, palpitations, high or very low blood pressure

Illnesses where symptoms seem vague or scattered could actually be providing warning signs that you have a problem with your thyroid. Diseases and syndromes such as chronic fatigue, fibromyalgia, menopausal symptoms, muscle and joint pains, IBS, PMS, heart disease or depression, which all have a wide variance in the symptoms they present with, may be improved when underlying thyroid issues are redressed. Sometimes an underactive thyroid can be due to an autoimmune disease, Hasimoto’s disease.

However, low thyroid function may actually not be the root of the problem. There is a strong relationship between your adrenal and thyroid glands and it is very common for adrenal fatigue to go hand-in-hand with hypothyroidism. In many cases the adrenal glands become weakened, leading to a malfunctioning thyroid gland. If treatment is only directed towards the thyroid gland and the adrenal issues are not addressed then the person’s health will simply not improve. It’s important to reduce stress in your life as both the adrenals and the thyroid are very sensitive to stress. Practicing meditation, yoga, qi gong, or relaxation techniques will go a long way to reducing the stress response and support the action of these glands.

Two hormones, T4 and T3 are produced by the thyroid. T3 is the active form of thyroid and is the one that does the vast majority of work in the body. When levels are low enough the traditional approach is to use synthetic hormone, but they only contain T4 and the problem with this is that most people have difficulty converting T4 into T3.

Thyroid hormone levels can be tested with a blood test. If symptoms are vague and do not point directly to a disorder, testing will probably be done alongside other blood tests.

The normal range for tests is 0.5 to 5.5 IU/ml.

The problem for many people is that they suffer symptoms of low thyroid function when their measured levels of the hormone are between 2.0 IU/ml and 5.5IU/ml – levels that are considered to show ‘normal’ thyroid function. They are told their levels are normal and left with no explanation or treatment for their symptoms. When it comes to thyroid hormones setting the boundaries of ‘normal’ for thyroid levels is very misleading as there really isn’t any ‘normal’ level…the levels change depending on factors such as age or health.

All the different hormones of the body work together in a delicate dance and when one is not working all the others are affected also. Many reproductive hormone-related symptoms may be experienced when thyroid hormones are low. PMS, infertility, fibroids, ovarian cysts, endometriosis, heavy bleeding, menopause symptoms, fibrocystic breasts or even post-natal depression may all result.

Low thyroid function can easily be confused with the symptoms of menopause. While symptoms such as hot flushes, period irregularities, weight gain, night sweats and insomnia are often experienced during peri-menopause or menopause, night sweats and insomnia in particular, may also be key symptoms of low thyroid function. Using hormone replacement to deal with these symptoms simply makes the problem worse, as the oestrogen in the medications interferes with the thyroid hormones further, impairing the thyroid function even more. This in turn slows down metabolism and leads to weight gain. It is a vicious circle.

As usual it is easy to point the finger at poor diet and lifestyle as contributing factors to thyroid dysfunction and sugar, processed foods, stress, lack of exercise or toxic environments all play their part.

WHAT CAN YOU DO?

Low thyroid function can be addressed in a number of more natural ways.

I treat many people (mainly women) for low thyroid function with huge success using carefully selected Homeopathic remedies, reversing their debilitating symptoms and allowing them to live a normal life. But with this being a complicated chronic issue it is not one that can be self-treated and requires prescribing by a fully-trained professional Homeopath.

But luckily there are a number of things that you can do as a first-line defense for hypothyroidism, and using natural methods avoids the side effects of medications.

DIET

A well balanced diet that is made up of unprocessed, unrefined whole foods, with organic or biodynamic vegetables, fruits, meat and dairy, is the best way to combat hypothyroidism, if you also include the following guidelines.

It’s so important that you stay away from sugar and caffeine which simply cause thyroid burn-out. If going ‘cold-turkey’ is too hard then cut back more gradually. Cut out refined and processed carbohydrates as well as they behave just like sugar when they are metabolized in your body.

Make sure to eat protein as it transports thyroid hormone into your cells. Include nuts, nut butters, legumes, quinoa, and less frequently and in smaller quantities eggs, meats, fish and dairy.

Good fats help to create hormone balance (including thyroid hormones) – avocados (one of my favourite good fat sources), coconuts and coconut milk and oil, olives and olive oil, raw nuts and nut butters, organic butter and yoghurt, organic egg yolks, flax seeds. Avoid trans fats.

Make sure you are getting enough Vitamins and minerals, especially Vitamin A, Vitamin D, the Vitamin B’s, iodine, selenium, zinc, copper, iron and omega-3 essential fatty acids. Organic produce will be higher in vitamins and minerals as long as it isn’t old and wilting.

Thyroid hormone production is just another of the many functions of Vitamin D which is produced in the body from sunlight. This is yet another reason to have levels of this crucial vitamin tested and maintained, and you may actually need to supplement this.

Cut out gluten especially if you have Hashimoto’s as the gluten mimics thyroid tissue and aggravates the autoimmune response

Watch out for foods that interfere with thyroid function especially those containing goitrogens and don’t eat them unless they are cooked – cabbage, broccoli, cauliflower, Brussels sprouts, kale, turnips, spinach, strawberries, peanuts, millet

Get tested for food sensitivities, especially if you find there is a food or food group that you crave, as eating these foods sets up an autoimmune response in the body.

The thyroid gland requires iodine to make thyroid hormones so iodine deficiency may be a contributing factor to hypothyroidism. Many people are deficient in iodine so include more sources of iodine in your diet like seaweed (kelp, dulce, nori), shellfish, saltwater fish, eggs, yoghurt, mozzarella cheese

SUPPLEMENTS

Supplement with probiotics as good thyroid function depends on healthy gut flora

Add vitamins and minerals particularly if you are not getting adequate amounts in your diet.

Other supplements that help thyroid activity and the manufacture of thyroid hormones are Tyrosine, Pantothenic acid (vitamin B5), magnesium citrate and Potassium iodide. Look for these in a combined thyroid supplement.

HERBS

Ashwaganda is a herb that can help to improve the level of T4 hormone and guggal Commiphora wightii to convert the T4 into the active T3. Guggal has been used for centuries in Ayurvedic medicine and is now difficult to source due to its scarcity after overuse – you may want to reconsider using this herb for this reason.

EXERCISE

Exercise lowers insulin levels and increases thyroid function. Work out or walk for 40 minutes three times a week, and make sure you get out of breath.
