We all know that winter weather calls for delicious, heart warming soups. This delicious pumpkin soup recipe has the added bonus of ginger – an ingredient that aids digestion and is packed with antioxidants that help prevent arthritis, inflammation and various types of infection. There are so many health benefits of ginger!

Ingredients

1kg pumpkin, peeled, seeds removed and cut into 4cm pieces

75g ginger, roughly chopped

2 garlic cloves

2 tbs extra virgin olive oil

1L (4 cups) vegetable or chicken stock

2 tbs finely chopped dill

1/3 cup (50g) toasted hazelnuts, chopped

Method

Preheat your oven to 180 degC.

Place your pumpkin, ginger and garlic on a large baking tray and drizzle with oil. Season, then toss to coat. Roast for 30 minutes or until the pumpkin is soft (don’t let the garlic burn).

Puree mixture in a blender or food processor with 2 cups (500ml) of stock, then season. If there are lumps then strain through a fine sieve. Place the soup in a large saucepan with remaining 2 cups (500ml) of stock and warm over a medium-low heat.

Divide the soup between 4 bowls and serve with dill and toasted hazelnuts and what ever other toppings you love on your soup – if you wish a dollop of marscapone.

Premenstrual Dysphoric Disorder (PMDD) is a health concern best described as a form of severe premenstrual syndrome (PMS). PMDD affects 3-8% of women worldwide but is not well understood or researched.

What are the symptoms?

PMDD symptoms include anger, irritability, depressed mood, anxiety, lack of pleasure, a sense of overwhelm, difficulty concentrating, fatigue, changes in appetite or food cravings, sleep changes, and physical symptoms such as breast tenderness, bloating or headaches.

These symptoms emerge in the luteal phase of the menstrual cycle, one to two weeks before periods commence, and typically subside within a few days of bleeding.

Over 64% of women experience some kind of mood changes a few days before the onset of menstruation. For women with PMDD these changes are more extreme. Despite having normal hormonal fluctuations during the menstrual cycle, women with PMDD experience an abnormal mood response to these fluctuations. Rage, anger, irritability, intolerance to others, anxiety and depression are commonly reported in women with PMDD. Our patients with PMDD sometimes say extreme statements along the lines of ” I get so mad I feel like I want to kill my husband before my period.”

It is suggested these more extreme changes in mood may be attributable to the effect estrogen and progesterone have on the serotonin, GABA and dopamine systems. These can also alter the renin-angiotensin-aldosterone system, which could explain some of the bloating and swelling that occur during the luteal phase.

Conventional intervention typically involves the contraceptive pill, anxiety medications and anti-depressant medications. For some women this relieves problematic symptoms but may also contribute to other side effects which become more of an issue than the PMDD itself. For those women, considering complementary solutions may be a good option. In traditional medicine practice, herbal medicines have been used to manage PMDD. Some of these natural medications support GABA levels, reduce extreme emotions, reduce depression, minimise physical symptoms and promote relaxation.

Other options often included in a herbal prescription such as withania , ginseng and rhodiola are considered serotonergic – i.e. they support level of serotonin in the brain. Nutrients such as vitamin E, vitamin D, zinc, vitamin B6, 5-HTP, calcium or inositol may be prescribed to help support healthy mood, reduce pain and support hormonal balance.

In naturopathic medicine we consider the individual’s unique presentation and symptomatic picture, rather than the diagnosis. Therefore, our treatment plans are also always tailored to the individual and consider their health history and current lifestyle demands. For some women anger is their key concern, while for others their depression is debilitating.

It helps to be realistic about what changes you can expect and appropriate timeframes. To get the best results we recommend an in-depth assessment and consultation for women with PMDD along with regular reviews to allow for modifications and adjustments of formulas and dosages.

Always seek medical care if you think you may have PMDD.

Most athletes consider the balance of electrolytes when thinking about hydration and recovery, especially over endurance events. But are salt tablets and electrolytes really necessary?

Before we answer this question, let’s recap on electrolytes and the role they perform in the body.

Sodium is the key electrolyte responsible for controlling extracellular fluid balance while potassium controls the fluid within the cells. Potassium also helps with muscle contraction and supports blood pressure. Electrolytes such as potassium can also impact iron absorption. Potassium (along with other nutrients such as zinc and B vitamins) is essential for hydrochloric acid (HCL) production in your stomach. Without adequate HCL a condition known as achlorhydria can develop where your ability to absorb dietary iron and the successful coordination of iron uptake, export, and iron storage as ferritin is reduced. This can lead to iron deficiency and anaemia as explained in this article.

Magnesium is well known for its role in nerve function, heartbeat regulation, energy metabolism and blood sugar stabilisation. Your muscles, brain and heart rely heavily on magnesium to do their job. As an electrolyte, magnesium sits both inside and outside cells and binds to water and interacts with other electrolytes. Calcium is well known for its role in bone health, heart and nerve function and less recognised as an electrolyte. Calcium sits within both intracellular and extracellular spaces. Other electrolytes include phosphates, chloride and bicarbonates.

Sodium and chloride are the two electrolytes lost in large quantities through sweat. The losses of these electrolytes are regulated in response to the balance of sodium consumed in the diet and recent sweat and urine losses.

So is the ingestion of electrolytes or salt tablets really necessary to enhance performance? Well yes and no. Confusing hey!

Why you should consider electrolytes.

Research suggests sodium added to drinks before exercise may improve the amount of that fluid retained, rather than lost through urination and potentially reduce the risk of dehydration. Sodium can also improve the flavour of drinks and encourage consumption when consumed during exercise. This could be handy in warmer conditions and when exercising for two or more hours. Sodium during exercise can also reduce the potential risk of developing hyponatraemia. It is suggested sodium can assist with fluid and carbohydrate absorption from the gut. If you are a heavy sweater with above average sodium loses (>1g/L) identified through sweat testing, then you may benefit from sodium ingestion during exercise if you are exercising for several hours.

The good news is that most sports drinks and gels contain sodium so it is unlikely the majority of athletes will need to take on additional electrolytes in the form of tablets. Ultra runners and ironman participants may be an exception to this rule.

Keep in mind the body has large stores of sodium that are released into the bloodstream as needed so it is unlikely you will ever run out of sodium unless severely dehydrated. The key reason why sodium is included in sports products is to balance out fluid intake and losses and maintain an appropriate osmolality, while improving the taste and increasing the palatability and consumption of the product, rather than preventing an actual sodium deficit.

And what about cramping?

Cramping is caused by multiple factors that can lead to changes in the nerves that control muscle contraction and muscle fatigue. Therefore, it is a little simplistic to suggest a single nutrient such as sodium or magnesium will prevent cramping. Further scientific research is required to give us clear guidance around cramp prevention. Many athletes do respond well to magnesium and a suitable hydration protocol.

Don’t forget you can also obtain electrolytes through wholefoods nutrition.

Sodium is easily found in most processed foods such as crackers, sardines, smoked foods, pickled foods, roasted seeds and nuts, cheeses, table salt and sauces.
Magnesium is found in pumpkin seeds, chia seeds, almonds, spinach, cashews, black beans, peanuts, oats, brown rice, and yogurt.
Potassium-rich foods include potatoes, sweet potato, dried apricots, and raisins, beans lentils, spinach, broccoli, avocado and bananas.

So before you reach for more artificial sports products consider if this is really necessary and if there are alternative ways you can provide your body with the electrolytes it requires.

Need specific guidance? We would be delighted to help.

Zinc deficiency and plant based athletes

Zinc deficiency is more common in plant-based athletes. Fact is, zinc is the powerhouse that supports performance. And knowing how being deficient in zinc can affect your progress, is essential.

Most athletes understand zinc’s role in supporting the immune system and wound healing, and its requirement for a proper sense of taste and smell but few understand its role in muscle function. It is a nutrient that needs to be consumed every day as the body doesn’t naturally produce zinc.

In our blog Robust immunity in athletes we outline the common signs of zinc deficiency, including frequent and prolonged colds, acne, dermatitis, low stomach acid, poor digestion, fatigue, and white spots or bands on nails.

In our previous blog Am I Deficient in Zinc? we outline how the high demands of sports make the elite athlete more vulnerable to illness, meaning over 65% of athletes experience regular colds and infections that sideline them from events and consistent training.

Zinc’s homeostasis is tightly regulated by different transport and buffer protein systems. Exercise has been shown to modulate zinc blood serum and urinary levels and could directly affect zinc transport around the body. The oxidative stress induced by exercise may provide the basis for the mild zinc deficiency observed in athletes and could have severe consequences on health and sports performance.

Importantly for athletes, zinc has been found to affect protein and muscle formation and regeneration due to its effects on muscle cell activation, proliferation and differentiation.

Plant based athletes in particular need to be aware of zinc rich sources, and food containing inhibitors of zinc absorption.

For vegan and vegetarian athletes, wholegrain cereals and legumes provide the highest concentrations of zinc, generally in the range of 2.5–5.0 mg/100 g raw weight. As zinc is contained within the outer layer of grains, unrefined whole grains provide higher concentrations of zinc than refined grains (up to 5.0 mg/100 g, compared with 1.0 mg/100 g).

Wholegrain breads and cereals, rolled oats, brown rice, nuts, seeds, legumes, tofu, soy products and fortified breakfast cereals are important dietary sources of zinc for everyone, not just vegetarians.

Fruit and green leafy vegetables have much lower concentrations of zinc due to their high water content. The good news is there is no evidence of greater risk of being deficient if intake of plant based zinc sources are adequate.

Well-planned vegetarian diets can provide adequate amounts of zinc from plant sources. Vegetarians appear to adapt to lower zinc intakes by increased absorption and retention of zinc. The inhibitory effects of phytate on absorption of zinc can be minimised by soaking, heating, sprouting and fermenting. Absorption of zinc can be improved by using yeast-based breads and sourdough breads, sprouts, and presoaked legumes.

Studies on runners indicate a drop in serum zinc following exercise and a higher excretion of urinary zinc than in sedentary populations. Zinc is vital for skeletal muscle, a tissue whose main function is contraction, force and movement production. As your body actually secretes zinc through sweat, it is essential for athletes to monitor zinc levels often.

It is super important not to just rely on just supplements to increase levels of zinc in your body. The risks of long-term zinc supplementation can have other potentially detrimental effects such as displacing other minerals such as copper and iron needed to form hemoglobin, therefore, increasing the risk of developing anaemia.

Zinc requires a fine balance between adequacy and deficiency and therefore essential to seek advice from a qualified practitioner who can determine the best course of action to avoid issues.

The high demands of sports make athletes more vulnerable to illness, with 65% of athletes experiencing regular colds and infections. Zinc is a key nutrient required for immunity and keeping an eye out for low zinc symptoms, may just make the difference between being sick or great performances.

It can be so frustrating to put in many months of hard training only to be sidelined during a taper or on race day by heaving lungs, debilitating fatigue, and a pounding headache. Sports performance is materialised through consistency, akin to writing a book, one page at a time. Forced breaks from training due to illness detract from progress and drains confidence. Not all athletes rest when unwell and opt to “push through” the illness only to experience prolonged symptoms and more disruption to competition.

Building a robust immunity is all part of a holistic approach to coaching and training. So how do you minimise your risk of getting sick?

There are many nutrients that contribute to a healthy immune system as discussed previously.

Athletes may be more susceptible to being deficient in zinc because exercise, particularly strenuous and endurance exercise, increases zinc requirements, encourages zinc loss through sweating, and changes zinc transportation and metabolism.

In our opinion, zinc plays the most critical role in supporting athletes and immunity.

Zinc’s role in hormone control and immunity

Zinc regulates several crucial processes in both your innate and adaptive immune system. Being deficient in zinc can lead to athletes becoming more susceptible to respiratory illness, particularly in the colder months.

Apart from zinc’s well-established role in immunity, this mineral, contributes to protein structure, regulates gene expression, metabolism and is the second most abundant trace element in the body after iron. Zinc deficiency can impact an athlete through hormone dysregulation (testosterone, thyroid, and growth hormones to name a few) and may affect erectile function and fertility.

Zinc is essential to maintaining optimum performance due to its function in metabolism and healthy cell division – essential in repairing damaged tissues after you exercise.

Studies show being deficient in zinc can lead to a reduction in the number of fast-twitch muscle fibres and muscle mass and performance decline. For Masters Athletes this is of particular relevance as aging is also associated with sarcopenia, the age-related loss of muscle mass, muscle strength, and physical performance.

Zinc also helps maintain blood sugar control and assists with muscle contraction during exercise, glucose metabolism, and glycogen storage.

Zinc also plays an essential role in antioxidant production by increasing antioxidant activity and inhibiting free radical production that may damage tissues, impact liver function, and prevent muscle exhaustion.

Low zinc symptoms

Apart from recurrent colds and other infections, there are many low zinc symptoms.

*Anxiety and depression

*Hormone imbalances

*Poor concentration

*Stomach pain and gas

*Slow healing

*White spots on nails

*Skin issues and acne

*Loss of appetite

*Loss or change of smell

*Changes in taste

Zinc rich foods

The most concentrated sources of zinc are contained in animal products, particularly meat, seafood and dairy. Vegan and plant-based athletes may be more susceptible to zinc deficiency due to reduced dietary intake, lowered gastric acid (which is zinc-dependent) and higher phytate consumption. Phytates found in plant-based zinc-rich foods such as legumes can inhibit zinc absorption.

Soaking nuts and seeds and legumes prior to cooking is a great way to minimise this issue and allow for greater micronutrient absorption.

Iron absorption

The gastrointestinal tract plays an important role in maintaining total body zinc homeostasis by regulating zinc absorption and excretion. In order to boost your absorption, the addition of a probiotic may be beneficial.

In certain situations, zinc supplementation may be recommended. The amount ingested, supplement form, and the timing of zinc matters. Speak to a naturopath or nutritionist with an interest in sport before self-prescribing. You’ll definitely want to avoid zinc toxicity. High zinc levels can have a detrimental impact on your performance through anaemia, copper and iron deficiency and unpleasant gastrointestinal side effects.

Zinc testing

Serum blood testing is used by some conventional practitioners to determine zinc levels in the body. Keep in mind 60% of zinc is stored in muscle and 30% in bone therefore serum may not be the best measure of zinc homeostasis. A mineral test can be another alternative method of assessing zinc levels and is available through our clinic as explained here.

If you need help building a robust immune system, book an appointment with our naturopath.

Iron deficiency is one of the most common issues athletes face. Iron and thyroid health go hand in hand and the effects of exercise on the thyroid gland and hormones are not well understood.

Iron and thyroid function
Undiagnosed iron deficiency presents an increased risk of impaired thyroid function. Active women have high-energy lives, managing work, family and training, and many will accept low energy and brain fog as simply a result of being overworked or as an inevitable part of hormonal changes.

However, low thyroid function, iron deficiency, overtraining and hormonal changes also present with many of the same symptoms.

Signs that your thyroid function may be underactive (hypothyroid) include fatigue, unexplained weight gain, headaches, low blood pressure, dry skin, constipation and cold intolerance. These early signs of cellular hypothyroidism can appear when blood pathology remains within standard ranges.

As with most chronic issues, there are multiple factors that may contribute to dysfunction.

The Link between Exercise and Thyroid Function

In athletes, endurance and high-volume training promotes thyroid function. During exercise, your hypothalamus stimulates the pituitary gland to secrete thyroid-stimulating hormone (TSH), which in turn signals your thyroid to synthesise and release the thyroid storage hormone T4 and active thyroid hormone T3.

These hormones influence your body’s metabolism and allow it to increase exercise intensity. Over time, this repeated, high demand of your thyroid during prolonged intense exercise may impact your thyroid function, causing it to slow down and consequently lose the ability to produce sufficient hormones.

Iron and Thyroid Function

Normal thyroid function is dependent on several nutrients to regulate the synthesis of thyroid hormones. Iodine, iron, tyrosine, selenium, and zinc are needed to facilitate the conversion of T4 to T3 . A deficiency of any one of these nutrients would result in reduced T3 production, causing you to experience hypothyroid symptoms. Vitamins A and D also play important roles in cell receptor behaviour to regulate thyroid hormone metabolism.

While iodine is the key mineral for healthy thyroid function (read more…here) it is not uncommon to find iron deficiency in hypothyroidism. Although widely recognised for its influence on red blood cell production, iron is also an important component of thyroid peroxidase, an enzyme essential for thyroid hormone biosynthesis.

Iron deficiency interferes with the normal functioning of the thyroid, contributing significantly to fatigue, exercise intolerance and lightheadedness.

Increased menstrual bleeding can lead to iron deficiency. Many of us dismiss low energy as a symptom of a busy, active lifestyle and so iron deficiency frequently goes undiagnosed in perimenopausal women. For athletes, iron plays a critical role in exercise performance as outlined in our blog “Increase your iron absorption and rebound from anaemia” here

The most common causes of iron deficiency include inadequate dietary iron intake, inflammation, poor iron absorption in the gut, parasites, iron loss through sweat, urination and faeces, blood loss through menstruation. Pregnancy, breastfeeding or high-volume exercise will also significantly increase iron demands. Take our free anaemia quiz to see if you may be iron deficient here

Thyroid Function and Sex Hormones in Women

Your thyroid function is sensitive to fluctuations in sex hormone levels, particularly oestrogen. Oestrogen stimulates the production of the thyroid hormone precursor, thyroglobulin, and increases the protein that carries thyroid hormones in your blood.

As oestrogen changes (such as during peri-menopause) so too does thyroid hormones, which play an important role in metabolism, muscle strength, energy production and expenditure, heart function, and temperature regulation.

As oestrogen levels rise and fall later in life, menstruation may become irregular and heavier. Peri-menopausal women may experience symptoms for over ten years as described in our blog on “Natural solutions for menopause” here .

During peri-menopause declining oestrogen may impact thyroid function and can lead to inadequate production and circulation of thyroid hormones.

Exercise During Hormonal Changes

Despite common misconceptions, women can train and perform well throughout peri-menopause, and beyond, if they listen to their bodies and be mindful of maintaining adequate dietary intake of key nutrients. It is important to recognise that both iron deficiency, thyroid function and hormonal changes can impact your ability to exercise.

Years of consistent exercise accumulate like pages in a book. As a mature you know your body very well. The pathway to success utilises your book of wisdom and skills. Mature athletes can benefit from greater recovery, individualized strength and conditioning and modified programs. Focussing on the balance between training intensity and volume will help you to achieve your desired goals.

If you suspect your symptoms are impacting on your quality of life and sport, it’s time to seek support to help you navigate the journey.

Blood serum pathology and functional tissue mineral testing can be a good starting point due to the critical role nutrients play in hormonal and thyroid function.

With the right self-care and a holistic approach to health, you can continue to achieve your life goals and physical challenges irrespective of hormonal changes.

Mineral and heavy metal testing can help to gain a better understanding of what metals may be impacting on health and what minerals are required to increase to enhance performance and overall health. Optimal nutritional balance is essential for the function of every cell and system in your body. Obtaining feedback on mineral absorption is just one of the benefits of mineral testing for athletes.

Mineral testing provides a wider perspective on an individual’s overall health status than just urine, blood or stool pathology testing alone although it is always useful to use both tests in conjunction with each other. Mineral testing can be used as an early detector of subclinical issues and provide useful guidelines in terms of how to best support the body when annoying symptoms such as fatigue, insomnia and digestion issues persist.

In clinical practice, test results are always accompanied by a thorough assessment of your overall health and nutritional intake to provide meaningful context to data and to give you a clear understanding of where and how deficits may be occurring.

A mineral analysis may provide insight into your current health status, identify potential areas of concern and provide suggestions around dietary and supplemental measures that may improve your health now and prevent issues in the future.

Mineral testing for athletes- useful insights

Mineral testing provides a snapshot of how the body is utilizing the nutrients obtained from your food and provides an analysis of 13 key minerals. Trends in nutrient deficiencies or excessive mineral levels may indicate poor activation and non-beneficial storage of nutrients.

To demonstrate this point, let’s take a look at calcium. Calcium will be maintained within a very narrow range in blood serum due to its life-supporting roles in managing heart rate, nerves, and muscle function. However, in a mineral analysis high or levels of calcium may be observed. Low levels of calcium may indicate poor absorption, inadequate intake or other nutrient issues such as low vitamin D, while high levels may be suggestive of low vitamin B6 and poor calcium utilisation in the body.

High calcium levels may also contribute to underactive thyroid issues with symptoms such as weight gain, fatigue, low blood pressure and poor mood. Early detection of calcium issues is vital for the prevention of bone issues such as osteopenia, fractures, bone spurs, kidney stones and thyroid issues.

Mineral testing for athletes provides an analysis of how the body is utilizing 13 key nutrients obtained from the athlete’s diet. Longer-term patterns in nutrient deficiencies or excesses may indicate poor activation and non-beneficial storage of nutrients.

High levels in mineral testing for athletes, may be suggestive of low vitamin B6 and poor calcium utilisation in the body.

Significance of mineral testing for athletes

A clinical understanding of how an individual metabolises and utilises nutrients can be obtained through various mineral ratios included in a mineral test. Just some of the ratios contained in the mineral analysis report are outlined below:

Immunity: Low zinc in relation to high copper levels may indicate a susceptibility to viral infections such as colds, cold sore outbreaks or poor wound healing. Zinc is critical to immune cell function and digestion and hydrochloric acid. Reduced digestive function and symptoms such as bloating, diarrhoea, malabsorption and low nutrient levels may also be observed in patients with low zinc.

Iron deficiency and anaemia: As discussed previously in relation to immunity, ceruloplasmin is a protein carrier shared by zinc, copper and iron. If zinc, copper or iron are too high, they may inhibit the absorption of the other minerals. For example -high levels of copper may be observed in women taking the oral contraceptive pill or through drinking water carried in copper pipes. High copper levels may contribute to iron deficiency anaemia and present as shortness of breath, lethargy, dizziness and exercise fatigue.

Poor liver detoxification: Molybdenum is a key nutrient required for liver detoxification and is frequently low on test results due to reduced intake of foods rich in molybdenum such as legumes. When molybdenum is low in relation to sulfur an individual may experience sluggishness, fatigue, skin issues, and poor recovery related to reduced sulfation detoxification pathways in the liver.

Blood sugar control issues: Manganese and chromium are key nutrients required for blood sugar control. When manganese is low in relation to chromium an individual may experience energy dips, especially after meals, sugar cravings and dizziness or sweating related to poor blood sugar control and fluctuating insulin levels.

Hormone issues: Minerals play a key role in hormone modulation. When iron is low in relation to copper, individuals may complain of fatigue, poor recovery, weakness, loss of libido, irregular periods and hot flushes due to a pattern of low progesterone or testosterone.

Adrenal gland insufficiency: During times of stress, the adrenal gland utilises larger amounts of sodium and magnesium. When sodium levels are low in comparison to magnesium the adrenal gland may be underperforming as it is highly sodium dependent to produce key hormones such as cortisol.

General muscle tightness: Calcium and magnesium are required for bone health and muscle and nerve function. Stiff muscles, bladder issues and immobile joints may present when there is an issue between the ratio of calcium and magnesium in the body.

HEAVY METAL BURDEN
This form of testing may also identify heavy metal burden on the body. Despite a clean lifestyle, individuals can present with unfavourable levels of mercury, arsenic, lead, tin or aluminium largely due to living in a modern environment where exposure to heavy metals occurs on a regular basis.

Contrary to popular belief, heavy metal accumulation does not necessarily occur from occupational exposure. Frequent exposure arises from pesticides; additives and the tinning of foods; dental fillings; drinking water; products and materials used in homes and offices; personal care products and cosmetics.

Heavy metals are neurotoxins and may over time contribute to a plethora of health issues such as thyroid, reproductive and mental health issues, and cancers. Heavy metals displace other key minerals such as zinc, selenium and iron. The presence of these metals may also be indicative of other functional issues such as reduced liver detoxification pathways.

Practicalities of mineral testing for athletes

Mineral testing looks at long-term trends (over 2-3 months) and can be very useful when symptoms or health issues are ongoing and underlying contributing factors are yet to be identified. Athletes also find mineral balance results useful before they launch a new training campaign as a measure of nutritional status and as a preventative measure against deficiencies that may inhibit performance.

Mineral testing does not require a blood draw and can be conducted in the privacy of your own home. Test results generally take 2 weeks and are reviewed during an extended consultation.
