Low Thyroid and Low Adrenal

A number of cases have been reported of individuals having signs of hypothyroidism with elevated TSH, and low free thyroxin concentration in conjunction with adrenal insufficiency. Adrenal hormone support resulted in normalization of thyroid function without any type of thyroid support. It is also reported by other researchers that patients with Addison’s disease or adrenal insufficiency also presented with hypothyroidism and became euthyroid following adrenal support. (Abdullatif, et al. 200)( Candrina, et al,1987)

Low Thyroid and High Blood Pressure

Hypothyroidism affects cardiac muscle contraction and contributes to high blood pressure due to increase stiffness of blood vessels and peripheral vascular resistance. Studies have shown that subclinical hypothyroidism may be an independent risk factor for the development of coronary artery disease, as well as congestive heart failure in older adults who have elevated TSH levels.

Low Thyroid and High Calcium

It is known that an increase in free intracellular calcium in adipocytes reduces their lypolytic response to catecholamines. In other words excess calcium has an effect of blunting the fat burning enzymes in fat cells, thus contributing to weight gain or an inability to lose weight. Parasympathetic dominant individuals who have hypothyroidism can often have a corresponding elevation of PTH, which increases calcium concentrations in fat cells. (McCarty, et.al. 2003)

Low Thyroid and High Insulin

Insulin can reduce metabolic rate due to insulin’s antagonistic effect upon the stimulatory, or thermogenic action of thyroid and adrenal hormones. Patients with adult onset diabetes have the typical triad of hyperinsulinism, parathyroid dominance and hypothyroidism. These endocrine changes are present long before clinical manifestations of diabetes. Attention to endocrine balance will aid in improving the resting metabolic rate, improve glucose control, normalize lipids as well as aid in weight loss. (Piolino, et al 1990)(Iitaka, et al. 2000)

Low Thyroid May Contribute To High Cholesterol

Patients with subclinical hypothyroidism have higher total cholesterol, LDL, triglyceride, apo B levels and LDL/HDL ratio compared to control groups. (Cabral, et al. 2004) Hypothyroidism affects cardiac muscle contraction and contributes to high blood pressure due to increase stiffness of blood vessels and peripheral vascular resistance. Studies have shown that subclinical hypothyroidism may be an independent risk factor for the development of coronary artery disease, as well as congestive heart failure in older adults who have elevated TSH levels.

Inactivity ‘kills more than obesity’

Inactive man
A lack of exercise could be killing twice as many people as obesity in Europe, a 12-year study of more than 300,000 people suggests.

University of Cambridge researchers said about 676,000 deaths each year were down to inactivity, compared with 337,000 from carrying too much weight.

They concluded that getting everyone to do at least 20 minutes of brisk walking a day would have substantial benefits.

Experts said exercise was beneficial for people of any weight.

Obesity and inactivity often go hand in hand.

However, it is known that thin people have a higher risk of health problems if they are inactive. And obese people who exercise are in better health than those that do not.

The study, published in the American Journal of Clinical Nutrition, attempted to tease out the relative dangers of inactivity and obesity.

Obese v inactive

Researchers followed 334,161 Europeans for 12 years. They assessed exercise levels and waistlines and recorded every death.

“The greatest risk [of an early death] was in those classed inactive, and that was consistent in normal weight, overweight and obese people,” one of the researchers, Prof Ulf Ekelund told BBC News.

He said eliminating inactivity in Europe would cut mortality rates by nearly 7.5%, or 676,000 deaths, but eliminating obesity would cut rates by just 3.6%.

Prof Ekelund added: “But I don’t think it’s a case of one or the other. We should also strive to reduce obesity, but I do think physical activity needs to be recognised as a very important public health strategy.”

Woman walking

Prof Ekelund, who is based in Norway, is into cross country skiing and clocks up at least five hours of vigorous exercise each week.

However, he says all it would need to transform health, is brisk walking.

“I think people need to consider their 24-hour day.

“Twenty minutes of physical activity, equivalent to a brisk walk, should be possible for most people to include on their way to or from work, or on lunch breaks, or in the evening instead of watching TV.”

The diseases caused by inactivity and obesity were largely the same, such as cardiovascular disease. However, type 2 diabetes was more common with obesity.

Tackle both

Commenting on the findings, Barbara Dinsdale, from the charity Heart Research UK, said: “This study once again reinforces the importance of being physically active, even when carrying excess weight.

“Changing your lifestyle is all good news for heart health, but physical activity is always easier to achieve and maintain without carrying the extra ‘body baggage’ of too much weight.”

Prof John Ashton, president of the Faculty of Public Health, said changes were needed to make exercise easier.

“We need substantial investment in cycling infrastructure to make our streets safer.

“If more people cycled or walked to work or school, it would make a big difference in raising levels of physical activity.”

Healthy eating: Is this the ultimate healthy meal?

A healthy meal with mackerel, potatoes, carrots, broccoli, and a slice of lemon all goes towards a balanced diet

The human body needs a balanced diet to deliver vital nutrients

What’s your idea of a perfect meal? Sushi? A large piece of cake followed by hot chocolate? Even if it satisfies your appetite, it’s unlikely to fulfil all your nutritional needs.

Cutting through the myriad of diet plans and faddish eating regimes, the human body needs a balanced, healthy eating plan to keep functioning properly. This helps ensure that our bodies have enough nutrition to:

  • Grow and build
  • Repair and heal
  • Reproduce successfully
  • Repel illnesses and infections
  • Avoid weight-related health problems

Eating a variety of foods can also reduce the risk of getting conditions including heart disease, stroke, some cancers, diabetes and osteoporosis.

What foods do our bodies need to stay healthy?

The foods we need to eat can be divided into five separate groups.

Food Group Main nutritional benefits How much should we have each day?
Fruit and vegetables(Includes fresh, frozen, juiced, dried or tinned fruit and vegetables) Vitamins, minerals and fibre Five portions
Starchy foods(Includes bread, rice, pasta and potatoes) Energy, fibre, and vitamins and minerals A third of everything we eat
Meat, fish, eggs and beans(Includes fresh meat, fresh and tinned fish, eggs, nuts and pulses) Protein and vitamins and minerals Two to three portions (one portion is an egg or a serving of meat/fish the size of a deck of cards)
Milk and dairy foods(Includes milk, cheese and yoghurt) Protein and calcium Two to three portions (one portion is a small pot of yoghurt or glass of milk)
Foods containing fat and sugar(Includes cakes, biscuits and fizzy drinks) Energy One portion (two biscuits or a small chocolate bar)

Why do we need these nutrients?

The reason we need a diet drawn from all of the groups is that they all deliver different, but vital, nutritional benefits to our bodies.

Fruit and vegetables are one of our main sources of vitamins and minerals, which the body needs to perform a variety of functions well. For instance, vitamin A helps to strengthen our immune system, B vitamins help us process energy from food, vitamin D helps us maintain healthy teeth and bones, and vitamin C helps to keep cells and tissues healthy. The steamed carrots and broccoli, pictured above, will maintain a higher proportion of vitamins than boiled or fried vegetables.

Fruit and vegetables (eaten with the skin on) also contain high amounts of fibre which help to maintain a healthy gut and digestive system.

Starchy foods, also known as carbohydrates, are where we get most of our energy from. Our bodies convert these foods into glucose which is used as energy either immediately or stored for later use.

Carbohydrates also contain fibre (especially wholegrain), and iron which we need to make red blood cells to carry oxygen around the body.

Meat fish, eggs and pulses provide us with significant amounts of protein which is essentially a building block of the body. Everything from our hair, muscles, nerves, skin and nails needs protein to build and repair itself. The grilled mackerel, pictured, is an excellent source.

Also high in protein are dairy products, and they are also great providers of calcium. The most common mineral in the body, calcium is needed for functions including helping blood to clot, and to build bones and teeth.

Fortunately, the fatty and sugary group, the foods that we find the most irresistible, also have a role to play, in moderation. Fat transports the fat-soluble vitamins A, D, E and K around the body. It also cushions and protects the internal organs.

Sugar is another food that gives us energy, whether it’s the naturally occurring fructose sugars in fruit or sucrose in table sugar. But, “other sources of carbohydrate, for example starchy foods, are a better choice for the nutrients they provide”, says Lydia Kelly, a specialist registered dietician who works for the NHS.

Healthy portions

So, how can we squeeze eating such a wide range of foods into one day? Lydia advises: “Try to base meals on starchy carbohydrates such as bread, pasta or potatoes. Include a range of different fruit and vegetables in your diet and try to have at least one to two portions with every meal. Including a moderate serving of protein-containing food is also important. Then choose adequate calcium sources, aiming for three portions of low-fat dairy or dairy alternatives daily.”

Whilst a small amount of sugary foods each day is acceptable, she warns, “eating sugar too frequently may increase risk of tooth decay. Weight gain may also occur if sugar in the diet provides more energy than we are using up”.

And many dieticians agree there’s no such thing as a ‘superfood’. The overall balance of the diet is what really matters, and guides such as theEatwell Plate can be helpful. No single food will provide all the nutrients we really need. And neither can one meal – so the plate of food above might be one healthy option, but a good diet should include a wide range of foods from each of the different food groups.

Don’t forget the fluids…

Fluids are also vital to help our bodies perform their functions effectively, and the best fluid of all is water. Two-thirds of a healthy human body is actually made up of water. It’s necessary to help our blood carry nutrients and waste around the body and to help the chemical reactions that occur in our cells.
