Energise Your Diet

by London Nutritionist Sylvia Hensher

One of the most common causes of visiting a healthcare practitioner is the complaint of fatigue. There are different kinds of fatigue. It may be constant, beginning in the morning after a full night’s sleep or it may build up throughout the day. Your nutritional status can and does play a major role in the prevention and treatment of fatigue.  Here are some factors to consider when trying maximising your energy levels throughout the day.

Nutritional causes of low energy

  • Eating refined carbohydrates and sugars: these are found in white bread, rice and pasta, cakes, honey, jam, soda drinks, sweets. These foods are digested quickly and therefore rapidly release sugar (glucose), the main source of fuel for our cells, into the bloodstream. This provokes the release of excess insulin, a hormone which controls blood sugar levels by stimulating cells to take up glucose, as excess glucose is toxic to tissues. Excessive amounts of insulin remove excessive amounts of sugar from the blood, which results in low blood sugar; this can reduce the glucose supply to cells which depend on glucose for energy and therefore reduce our energy levels.
  • Food sensitivities: allergenic foods can act as a stressor on the body and lead to low blood sugar so that cells lack enough sugar (glucose) for optimal functioning, making you feel tired.
  • Nutrient deficiencies such as B and C vitamins, iron, magnesium, zinc and copper which are needed for energy production can lead to low energy
  • Stimulants such as coffee, chocolate and nicotine increase levels of the stress hormones cortisol and adrenaline (1) which sharply spike up blood sugar levels. This causes the release of large amounts of insulin to remove the excess sugar which is not used by the body and subsequently leads to an energy slump.
  • Dehydration every cell in your body needs water for a myriad of chemical reactions, including the burning of glucose and the breakdown of fat for energy production.

Other causes of low energy

  • Stress leads to a sugar imbalance because it triggers the release of hormones such as adrenaline and cortisol which increase blood sugar levels. This stimulates the release large amounts of the hormone insulin, which removes the excess glucose from the blood, leading to low blood sugar and insufficient energy supply to our cells
  • Anaemiathis refers to a condition in which the blood is deficient in red blood cells or the haemoglobin (iron-containing) portion of red blood cells. The function of red blood cells is to transport oxygen from the lungs to the tissues of the body and help turn fats, carbohydrates and proteins into energy. Thus a lack of red blood cells reduces the amount of oxygen being delivered to tissues and thus energy levels. Iron, vitamins B12 and folic acid are needed to make properly functioning red blood cells, and anaemia may be caused by a shortage of these nutrients.  These nutrient deficiencies may be due to a poor diet, heavy menstrual bleeding, pregnancy or poor nutrient absorption as found in coeliac disease and Crohn’s disease.
  • Poor adrenal functioning-the adrenal glands sit on top of the kidneys and The adrenal glands are situated on top of the kidneys and one of their main jobs is to release hormones which help the body maintain a state of alertness as well as help raise  blood sugar levels when they are low. If the adrenal glands are overworked due to constant uninterrupted stress and poor nutrition, their ability to produce hormones which help maintain steady blood sugar levels can become compromised.
  • Poor thyroid functioningThe thyroid controls energy production, so an underactive thyroid can result in reduced energy production, making us feel tired..

The Thyroid, Adrenals And Weight Gain

by London Nutritionist Sylvia Hensher

There is a connection between our adrenal glands, thyroid glands and weight gain. When these two glands are not kept in a healthy state, the result can often be weight gain. The good news is that on the other hand, if these two glands are supported through proper nutrition and a healthy lifestyle, it can lead to a natural weight loss.

What our adrenal glands do

The adrenal and thyroid glands are very closely connected in how they enable the body to function properly. The adrenals are small triangular shaped glands that sit on top of both kidneys. They are responsible for releasing the hormones adrenaline and cortisol which among other functions, help control body fluid balance, blood pressure, blood sugar and are designed to help the body deal with physical and psychological stress. In addition, the adrenal glands produce small amounts of oestrogen when women enter into menopause and the ovaries reduce their oestrogen output. This is why it’s so important to maintain adrenal function in the menopause years.

Adrenal Fatigue

Adrenal Fatigue is a collection of signs and symptoms, known as a “syndrome” that results when the adrenal glands function below the necessary level.  This happens most often when you are exposed to constant , uninterrupted stress so that your body (and adrenal glands) cannot fully recover, or during or after acute or chronic infections. Consequently, the adrenal glands become fatigued and are unable to continue responding adequately to further stress.

You may look and act relatively normal with adrenal fatigue and may not even have any obvious signs of physical illness, yet you live with a general sense of feeling unwell, tiredness or “grey” feelings. People suffering from Adrenal Fatigue often have to use coffee, tea and other stimulants to get going in the morning and to prop themselves up during the day.

Nutritional Support for a Healthy Weight & Thyroid

PART 2

by London nutritionist Sylvia Hensher

Hi again! In part 1 of this series on the thyroid we talked about what the thyroid is, how it might be affecting your weight, symptoms of an underactive thyroid and a simple test you can do at home to give you an indication, but no firm diagnosis, as to how well your thyroid is functioning.

In this 2nd part of the series, we’ll look at how you can support optimal thyroid functioning, and therefore optimal weight management, through nutrition.

Foods to help support optimal thyroid functioning

1. Iodine is required to manufacture the thyroid hormones. Without sufficient iodine, your thyroid cannot produce adequate thyroid hormones to help your body function on an optimal level. Seafoods, iodised salt and sea vegetables such as kelp, as well as foods grown in iodine rich soil, are rich sources of iodine. It should be noted, however, that too much iodine can actually trigger thyroid problems and worsen symptoms, so it’s important to have a healthy balance.

2.       Zinc is another essential mineral for optimising thyroid health.

3.      Selenium: This mineral is critical for the proper functioning of your thyroid gland, and is used to produce and regulate the active T3 hormone. Selenium can be found in foods such as shrimp, snapper, tuna, cod, halibut, calf’s liver, button and shitake mushrooms and Brazil nuts.

4.      Zinc, Iron and Copper are needed in trace amounts for your healthy thyroid function. Low levels of zinc have been linked to low levels of TSH, whereas iron deficiency has been linked to decreased thyroid efficiency. Copper is also necessary for the production of thyroid hormones. Seafood, whole grains, green leafy vegetables, nuts and seeds can help provide these trace metals in your diet.

5.      B vitamins help to manufacture thyroid hormones and play an important role in healthy thyroid function. They are found in whole grains, pulses and green leafy vegetables. Continue reading “Nutritional Support for a Healthy Weight & Thyroid”

Is Your Thyroid Sabotaging Weight Loss?

Part 1

By London nutritionist Sylvia Hensher

Have you tried every diet known to man, really watch what and how much you eat, exercise regularly and find that you STILL CAN’T LOSE THE WEIGHT???!! Well, here’s some good news. Research is pointing to the fact that an underactive thyroid might be the number one cause of weight problems, especially among women.

So what is the thyroid and how might it be affecting your weight? Well, the thyroid gland is a small butterfly shaped gland with two lobes found just in front of your neck below the Adams Apple. One of its main functions is to control metabolism- that is, the rate at which we burn calories to maintain vital functions. Our bodies need fuel just as a car needs fuel to power itself, so whether we are sleeping, shopping or exercising, we are constantly burning calories.

Now, your thyroid gland produces two main hormones. One is called thyroxine (T4) and the other is called triiodothyronine (T3). The thyroid produces approximately 80% T4 and 20% T3. T4 is generally considered to be inactive and only becomes active when converted to T3, although some researchers believe that T4 does, in fact, have a function. T3 is an active hormone needed by all of the cells and tissues of the body and is the one which does all the work of regulating the body’s metabolism.

Thyroid problems often run in families and can happen at any age. Things can go wrong with the thyroid in two ways:

Hyperthyroidism, also called an overactive thyroid where the thyroid produces more thyroid hormone than it should which causes the metabolism to run too fast.

Hypothyroidism, also called an underactive thyroid where the thyroid doesn’t produce enough thyroid hormone which causes our metabolism to work too slowly.

What are the symptoms Of An Underactive Thyroid (Hypothyroidism) Continue reading “Is Your Thyroid Sabotaging Weight Loss?”
