Iodine

Iodine is the Greek word for 'violet', the colour of this important mineral. The main functon of iodine is to produce hormones in the thyroid gland and is found in seafood and seaweed. Goiter which is an enlargement of the thyroid gland, is common in parts of the world where the soil lacks iodine. In these areas sea salt is recommended as a natural supplement.


Special notes:
Iodine is toxic in high doses and may aggravate or cause acne. Large doses may interfere with hormone activity.

Cruciferous foods such as cabbage, brussels sprouts, cauliflower and broccoli contain substances that can cause hypothyroidism by antagonizing iodine, but cooking will prevent this. Anyone who eats large quantities of these vegetables should consider an iodine supplement.

Dosage is best taken as potassium iodide or as seaweed products. Take under the supervision of a GP or nutritionist.


Data:
Iodine is a mineral first discovered in 1812 in kelp. Iodine was extracted and named iodine because of it's violet colour. Iodine occurs naturally and is a crucial part of the thyroid hormones that regulate our energy levels. Iodine is found in seafood and seaweed and most table salt is fortified with iodine.


What's iodine good for:
Helps protect against toxic effects from radio active materials.

Prevents goiter.

Produces hormones from the thyroid gland.

Promotes healthy hair, skin, nails and teeth.

Burns excess fat.


Deficiency symptoms:
Deficiency is very common in many parts of the world, where iodine is not found in sufficient quantities in the soil and as a result the incidence of goiter and cretinism is very high.

Studies show that iodine deficiency is also linked to Parkinson's disease, cancer of the thyroid, multiple sclerosis and Alzheimer's disease among others.

Deficiency sysmptoms include an enlarged thryoid, dry skin, neurological problems, excess estrogen production, chronic fatigue, apathy, and reduced immune activity.


Good sources:
Fish and seafood, pineapple, raisins, seaweed, dairy produce.


Therapeutic uses:
Cuts and wounds (as an antiseptic, used externally), goiter, fibrocystic breast disease, thyroid problems.

Quick guide to vitamins and minerals

Vitamins

Vitamin A – for growth and immune system function. Found in milk, cheese, egg yolk.

The B Vitamins – for immune system function, and assisting the body in releasing energy from food. Found in lean meats, poultry, dairy, wholemeal and wholegrains.

Vitamin C – for healthy skin, bones and gums. Also increases iron absorption. Found in broccoli, cauliflower and citrus fruit.

Vitamin D – helps with calcium absorption for strong bones and teeth. Found in oily fish and eggs.

Vitamin E – protects the cells in the body from damage and disease. Found in nut oils, sweet potatoes.

Vitamin K – for blood clotting. Found in green leafy veg such as spinach and broccoli.

Minerals

Iron – for healthy blood and brain development. Also important in transporting oxygen around the body. Found in lean meats, poultry, legumes, eggs and dark green leafy veg.

Calcium – for growth and maintenance of healthy bones and teeth. Found in dairy products, leafy green veg, fortified bread.

Selenium – has antioxidant properties that protect the body’s cells from damage. Found in fish, lean meat, poultry, dairy products.

Zinc – for growth and immune function. Found in lean meat, chicken, milk and cheese

The Department of Health recommends that it’s important that each meal throughout the day is made up of food from each of the 3 nutrients:

• Carbohydrates – provide energy to fuel the body. Includes complex ‘starchy’ carbs such as bread rice, potatoes and pasta; as well as fruit and veg. Fruit and veg are especially important as they also provide fibre and vitamins and minerals. Nutritionally, frozen fruit and veg are just as good as fresh, and you can also give dried and canned varieties (but be wary of added salt or sugar)

• Protein: – the ‘building blocks’ for growth and development. Meat, fish, eggs and dairy are the best sources of protein. Remember that when it comes to dairy, whole cow’s milk is better than skimmed for under-2′s as it is a rich source of several nutrients. Pulses and beans like lentils and chickpeas are great non-animal sources of protein.

• Fats – provide a long term store of energy for the body. They also help provide insulation and to control body temperatures. Be wary of trans-fats, often declared as hydrogenated fats on ingredients labels, which are sometimes found in chips, crisps, cakes and biscuits. Focus instead on the ‘healthy fats’ like omega 3 – an essential fatty acid which is needed for brain development and other important bodily functions. Fish – particularly oily fish, is a wonderful source of omega 3, as is rapeseed oil and olive oil.

So how much of all of these foods should be eaten every day?

Starchy carbohydrates
4 servings a day

Fruit and vegetables 
5 servings a day

Protein - non-dairy sources
2 servings a day

Protein - dairy
3 servings a day to hit calcium requirements

Fats
Allow some fat each day with, but not instead of, the other nutrient groups.
To ensure adequate intake of Omega 3, aim for 2 servings of fish a week, 1 of which should be oily.

Essential Fatty Acids

Essential Fatty Acids, also called E.F.A.s, are fats required by the body, but not manufactured by it. They work to strengthen the membranes of the cells and to promote the growth of muscles and nerves. Fish oils and evening primrose oil are among the richest dietary source of essential fatty acids.

 
Tinned fish is often fresher than 'fresh' fish as it is frozen, cooked and canned within 2 days whereas 'fresh' fish can be up to 14 days old when sold. Tuna is the only tinned fish which loses it's omega-3 on the canning process.

Natural anti-inflammatories, E.F.A.s are useful in the treatment of arthritis, asthma and a number of skin conditions. They are also used therapeutically to thin the blood and to prevent blood clotting.

 

The two main essential fatty acids are linoleic acid and linolenic acid, also known as omega-6 and omega-3 oils respectively. Both are vital for the brain and nervous system, the immune system, the hormonal system, the cardiovascular system and the skin. The first sign of their deficiency is a dry skin, dry eyes and a greater than normal thirst.

 

Seeds in general but especially sesame and sunflower seeds are rich in linoleic acid (omega-6), while pumpkin and flax seeds (edible linseeds) are rich in linolenic acid (omega-3).

 

Linoleic acid (omega-6) converts in the body into two further substances: gamma linolenic acid (G.L.A.) and di-homo-linolenic acid (D.G.L.A.) which is further converted to arachidonic acid (A.A.).

 

Linolenic acid (omega-3) is converted into eicosapentoniic acid (E.P.A.) and docosahexenoic acid (D.H.A.)

 

E.P.A. and D.H.A. are also found in fatty fish such as mackerel, herring, salmon and sardines.

 

Further to this D.G.L.A., A.A. and E.P.A. go on to produce prostaglandins which have a regulatory effect on the body and an anti-inflammatory effect.

 

Research suggests that E.F.A.s are necessary to balance the calcium in the body, particularly the bones. Omega-3 oils may slow down the loss of calcium in the urine, which includes some lost from the bones. Omega-6 oils will help the body to absorb calcium.

 

 

What's good about fish oils:

• Can counteract the effects of some immunosuppressive drugs.
•  
• May help the treatment of kidney disease.
•  
• May help prevent cancer, in particular breast cancer.
•  
• Stops the progression of arthritis.
•  
• May help to protect against hypertension (high blood pressure).
•  
• May help to treat psoriasis.
•  
• Fish oils are now believed to improve overall health conditions, the best sources of which are herring, salmon, tuna, cod and prawns.

 

For most people it is enough to increase intake of fish and seafood in order to achieve benefits of fish oils in natural form without taking supplements. People suffering from arthritis or psoriasis can take up to 4g daily fish oil supplements with physician supervision. Maximum suggested dosage without physician supervision is 900mg per day. Caution - fish oils may be harmful in diabetics since they can cause an increase in blood sugar level and a decline in insulin secretion.

Spirulina (algae)

Algae are plants that grow in water. Spirulina is a tiny water plant which grows in water, probably the most important in health terms, of all algae. High in proteins with a wide range of other nutrients including beta-carotene which offers protection by boosting the immune system and it is particularly valued by vegetarians.   Spirulina, a blue-green bacteria or algae is also rich in Linolenic acid (omega 3) which is necessary for the production of prostaglandins for an anti inflammatory effect. GLA (gamma linolenic acid) has been proven to improve symptoms of diabetes significantly.

 

Spirulina was used as a staple food by the Aztecs of Mexico and is now marketed as a high protein food supplement.

 

Seaweeds are another form of algae too, and it is thought to have many qualities, including an ability to protect against cancer. Seaweeds may help to reduce the effects of carcinogenics including radioactive material and are therefore useful for reducing the damage done by chemotherapy and radiotherapy.

 

Seaweeds appear in many foods, medicines and cosmetics and have been used therapeutically for thousands of years Rich in iodine they are used worldwide in the treatment of goiter. They are believed to have antiviral activity.

 

Seaweeds are believed to be natural antacids and are useful in treating intestinal disorders.

 

 

What's good about algae?

• Rich in nutrients and high in protein (particularly useful for vegetarians)
•  
• May help to suppress the appetite
•  
• Used to maintain skin health and to treat skin disorders
•  
• May help to contribute to the health of intestines
•  
• General tonic properties
•  
• Many have anticancer properties

Magnesium

The mineral magnesium is required for virtually every biochemical process in the body including metabolism and the synthesis of both nucleic acids and proteins and deficiencies are fairly common. Many symptoms can signal deficiency, including a poor circulation, palpitations, muscles spasms and cramps, nervousness and anxiety among others. Stress can deplete magnesium levels as can a high consumption of tea and coffee. Magnesium deficiency is common among those who exercise too hard.

What's good about magnesium:
repairs and maintains body cells
necessary for hormonal activity of the body
required for most body processes including energy production
balances and controls potassium, calcium and sodium
helps to bind calcium to tooth enamel
antidiabetic
required for contraction and relaxation of muscles including the heart
required for transmission of nerve impulses
required for growth and repair
necessary for bone development

Good sources:
Brown rice, soybeans, black eyed peas, nuts, brewer's yeast, wholegrains, bitter chocolate, legumes.
NB: Magnesium supplements can be toxic to people with renal problems or atrioventricular blocks. Otherwise magnesium should be very safe. Very rarely symptoms of excess can occur including flushing, of the skin, low blood pressure, thirst and shallow breathing. The contraceptive pill, chronic diarhea, IBS, high consumption of tea and coffee and use of laxatives will also compromise magnesium levels. Stress both emotional and physical can deplete magnesium levels and requirements will increase in stressful periods of life.

Essential Fatty Acids

Omega-3

Vitamin E

Vitamin E is an antioxidant vitamin with a wide range of therapeutic uses. Although this vitamin is fat-soluble, it is stored less efficiently by the body than most, and very vulnerable to processing; 90% is for example lost when wheat is refined into white flour.

Smokers and women who take the contraceptive pill have additional Vitamin E requirements.

Vitamin E is a fat-soluble vitamin, but unlike other fat-soluble vitamins, up to 70% is excreted in the faeces each day. It is stored in the liver fatty tissues, heart, testes, uterus, muscles, blood and the adrenal and pituitary glands.

Vitamin E is chemically known as alpha tocopherol, the most active group of a group of eight tocopherols. It has a huge number of therepeutic properties and is used in the treatment of many health disorders including coronary heart disease, muscular dystrophy and schizophrenia. It has also been used successfully in the treatment and prevention of some cancers.

Smokers and some woman taking the contraceptive pill will need extra vitamin E since both are reported to lead to deficiency, vitamin E is easily destroyed by heat, oxygen, freezing, food processing and chlorine (found in some drinking water). Frozen foods, particularly those that have been frozen longer than two months are likely to have negligible vitamin E content.

What's good about Vitamin E:

Slows the aging process. Regular use of Vitamin E skin cream helps to slow down the degenerative aging process.
Provides the body with oxygen
Protects lungs against pollution
Helps the development of nerves and muscles
Helps to prevent miscarriages
Improves immune activity in the body
Works as a natural diuretic
Heals the skin and helps prevent scarring
Improves fertility

Deficiency Symptoms:

Muscle degeneration, reproductive problems, some aenemias, age spots, cataracts, infertility, fragile red bloods cells and some nueromuscular damage.

Good sources:

Wheatgerm, soybeans, vegetable oils, broccoli, leafy green vegetables, whole wheat, eggs, oats, almonds, butter, peanuts, sunflower oil, seeds.
