What’s the fuss with fermented food?

Why eat fermented food?

Fermented foods seem to be all the rage lately, but these foods have been a staple in many diets for centuries. The health and type of bacteria present in the gut is the basis for good gut function and health, particularly a healthy immune system. The average person has between two and four kilograms of bacteria in their large intestine and these bacteria have very important tasks. Recent research has even shown that the proportion and type of gut bacteria present in a person can affect weight loss.

Good digestion and gut health are founding principles of good health, and fermented foods can go a long way to help improve the ratio of beneficial gut bacteria.

What are fermented foods?

These are some of our favorite fermented foods that are easy to incorporate into your meals each day:

Sauerkraut

Sauerkraut is lacto-fermented vegetables, traditionally cabbage, meaning that it is fermented using primarily the lactobacillus strains of bacteria. Bacteria eat up the sugars in the vegetables and leave behind lactic acid which is what preserves the vegetables. The benefit of this process is that the lactobacillus bacteria are also left behind, helpful bacteria for the human gut. The fermentation process also makes the vegetables easier to digest and preserves the nutrients and enzymes present in the vegetables.

Sauerkraut can be added to salads at lunch, eaten along side dinner, eaten with eggs at breakfast or on its own as a snack. There are many different types of sauerkraut on the market, ones made from cabbage, beetroot, cauliflower, and carrots. Or you can make your own!

Kim Chi

Kim Chi is a Korean version of sauerkraut, it is made with cabbage, bok choy, radishes, chili and ginger. Many people enjoy Kim Chi in veggie broths, with stir-fries or as an accompaniment to fried rice.

Kombucha

Kombucha is fermented tea. It is made using black and green tea with sugar and a starter culture. It is fermented for 10-14 days over which time the bacteria in the culture eat (use up) the sugar leaving behind a subtly sweet and sour fizzy drink. Kombucha is an easy way to add a dose of good bacteria to your diet. The Dr Libby Team likes to have a few bottles stored in the office fridge for the late afternoon, and some of us choose to start our day with a glass of kombucha, too.

If buying kombucha look out for brands that are made using natural ingredients (no preservatives), and brands that don’t add sugar post fermentation. You want the sugars to be used up during the fermentation process. Some yummy options are kombucha with ginger or turmeric added to it.

Miso

Miso has a wonderfully savoury flavour and can be used in broths, soups, or in dressings. It is produced by fermenting soy beans with salt and fungus. Miso supports the good bacteria present in the gut and is a source of B vitamins and several antioxidants, both of which are needed for great energy and to reduce inflammation in the body. Be sure not to heat the miso too much as it kills off some of the helpful bacteria. Stir it into warm liquids to keep the beneficial bugs alive. When purchasing miso paste look for a non-pasteurised version to be sure you are getting the benefits of the bacteria.

Tip

Look for organic fermented foods so that artificial substances don’t potentially interfere with the production and quality of the beneficial bacteria in the foods.

5 Tips to save your skin this winter

Dry, flakey skin doesn’t have to be your reality this winter. Here are our five top tips for glowing skin this winter.

Hydrate

Skin loves hydration! Your skin is your biggest organ and it needs a steady supply of fluid to stay hydrated, plump and glowing. Ensure that you are drinking plenty of filtered water, herbal tea, organic bone broth and veggie juices to help keep your body and skin hydrated. Fluids also help to flush out any harmful substances from the body and prevent these substances from needing to be excreted through the skin, where they can cause damage.

Nourish

Start by eating real food. Real food, as it comes in natures is packed with a range of nutrients, all of which promote great skin. Avoid processed food, caffeine and alcohol and notice the difference this makes to your skin. Vitamin C is particularly helpful for skin as it helps to combat free radical damage, which is part of the cause of aging and wrinkles. Vitamin C rich foods include citrus fruit, kiwi fruit, capsicum and broccoli.

Skin loves fat! Fat helps the skin to maintain its moisture barrier which helps keep skin soft and prevent drying. Flaky and dry skin or cracked heels and cuticles can be a sign that you are lacking in essential fatty acids. Omega 3 fatty acids are particularly helpful for skin, and is the type of fat that most people are deficient in. Oily fish like sustainable sardines or salmon, chia seeds, flax seeds, and walnuts are all great omega 3 rich fats to include in your diet. Coconut oil also makes a great topical moisturiser to use on dry patches of skin.

Be careful with your skin

Your skin is a delicate organ, so be aware of what you are allowing to come into contact with it. Every day our skin is exposed to substances in the air and from our environment that are less than ideal, so it is important to not compound this problem by using harmful skincare or make up products as well. Look for skin products that use organic ingredients and are free from synthetic substances. This ensures that the products we use to assist the outside aren’t doing more harm than good.

Consider not wearing make up all of the time. Give your skin a break, prevent clogged pores, and allow it to breathe. Keep your hands away from your face as much as possible, as our hands are covered in bacteria and it is best not to transfer this bacteria to our face where it can cause problems.

Start brushing

Dry brushing is when you use a soft bristled brush to brush your skin. This technique increases blood flow to the skin, boosts lymphatic drainage – which helps remove waste products from the body, and exfoliates the skin. Always brush towards the heart. After brushing apply nourishing oils like coconut or olive oil to hydrate your skin.

Look after your gut

The face is a useful tool for exploring deeper issues. Flare ups of pimples, acne, rosacea, eczema, and rashes are a signal that other body systems may not be functioning at their best. More often than not it is the gut that is not as happy as it could be. Poor digestion can lead to liver detoxification pathways that then struggle to clear unwanted substances from the body. When these substances are not eliminated efficiently the body looks for another way to excrete them and the skin is then used as an excretory organ. This can trigger pimples, rashes and other skin troubles. A diet high in plant foods, lots of water and avoiding caffeine, trans fats, processed sugars and alcohol can all contribute to good digestion and happy, radiant, clear skin.

The Science and Impact of Rushing

Rushing Woman’s Syndrome  is the name of the second book I wrote in 2011. The book initially evolved out of my observation of a shift in women’s health and behaviour in my practice over the previous 16 years. Never before in my work had I witnessed so many females in a rush to do everything and be all things to all people. Never before had I seen the extent of reproductive system and sex hormone challenges that I was seeing. Women were wired. Many of them tired too. Tired yet wired. And this relentless urgency, this perception that there was not enough time, combined with a to-do list that was never all crossed off was having such significant health consequences for women that I had to write about it. I didn’t want these amazing mothers, sisters, daughters, friends and colleagues to compromise the quality of their lives in order to live up to this perceived urgency.

Not that long ago in human history women were given the opportunity to do what had traditionally been their father’s jobs, while maintaining what were traditionally their mother’s responsibilities and what has unfolded for too many women is a frantic double shift, of working day and night, with very little if any rest.

We’ve made more progress in the workplace than we have in the home. Research shows that if a woman and man both work full time and have one child, she does twice the amount of housework and three times the amount of childcare he does. So essentially, she has three jobs and he has one. It is time for the dawning of new era for women, which means it has to be for our men as well.

The perceived need to rush, whether a woman displays it on the outside or keeps it under wraps, is changing the face of women’s health as we know it in a detrimental way; from PMS to IBS, from losing our tempers to feeling like we can’t cope.

Rushing Woman’s Syndrome describes what is scientifically known as Sympathetic Nervous System Dominance and the biochemical changes this drives in the body (see extended explanations of the science below). I wanted women to understand the significant way stress can impact the chemistry of their body, the many body systems it can affect, and offer them practical solutions to this.


The role of the nervous system
The nervous system plays a significant role in the stress response and it has a number of parts. The two branches related to this concept are the sympathetic nervous system (SNS), also known as the amped up “fight or flight” response, and the parasympathetic nervous system (PNS), the calming “rest, digest, repair and reproduce” arm of the nervous system. The challenge for too many women today is that they live in SNS dominance and this can play havoc with weight management, food cravings, sleep quality, patience, moods, self-esteem, and overall quality of life.

One of the hormones driving this is adrenalin, which communicates to every cell in the body that your life is in danger. As I described in my TEDx talk science suggests humans have been on the planet for between 100,00 and 150,000 years and for the entirety of that history, that’s what adrenalin has meant to the body. The nervous system doesn’t know that the adrenalin amping you up is not from a physical threat to your life but rather your body’s response to the caffeine you drink and/or your perception of pressure.

When we live on adrenalin we tend not to sleep restoratively, crave (and give in and eat!) sugar despite our best intentions, and find it harder and harder to utilise stored body fat as a fuel, instead burning glucose. Yet when we primarily burn glucose as a fuel (instead of body fat), because it is our “get out of danger” fuel, the body can’t risk the glucose fuel tank getting too low so the desire for sweet food gets switched on… hello harsh self-talk when you give in to your sweet cravings even though you said you wouldn’t.


Sex 
hormone imbalances
One of the biggest challenges facing women’s health today is the way stress hormone production is interfering with sex hormone balance. Too many women now suffer with premenstrual syndrome (PMS), PCOS, endometriosis and experience debilitating menopauses, which can have both physical and emotional health consequences.

From painful periods to fluid retention, from anxiety to yelling at the people we love the most in the word and berating ourselves afterwards, it has been a long time since women’s health has faced such an intense hormonal challenge. This interference of stress hormones with sex hormones is one of the major biochemical factors I describe in Rushing Woman’s Syndrome.

Estrogen and progesterone are two of a woman’s sex (steroid) hormones and their ratio to one another has the potential to make us happy or sad, vivacious or anxious, pimply or clear skinned, and our clothes looser or tighter. Big roles for two little hormones!

For the first half of the menstrual cycle, estrogen is the dominant hormone, laying down the lining of the uterus. Estrogen wants a menstruating female to get pregnant every month of her life, whether that is on her agenda or not!

For the first half of the cycle, we make a small amount of progesterone from our adrenals glands, walnut sized-glands that sit on top of our kidneys. Progesterone’s job reproductively is to hold the lining of the uterus in place, yet it performs a host of other biological functions aside from those involved in reproduction.

Progesterone acts as an anti-anxiety agent, an anti-depressant and a diuretic, allowing us to excrete excess fluid. However, our adrenal glands are also where we make our stress hormones from; namely adrenalin and cortisol. As you now know, adrenalin communicates to every cell in your body that your life is in danger, while cortisol says that food is scarce. As your body links progesterone to fertility, the last thing it wants for a woman is to bring a baby into an environment where it perceives she is not safe and that there is no food. The body, therefore believes that it is doing you a great big favour by shutting down the adrenal production of progesterone.

Park the fertility aspect of what I’ve just said and consider the additional biological impacts of this: we make too little of a hormone that helps us not feel anxious, not have a depressed mood and allows us to efficiently mobilise fluid. If a woman retains fluid, she usually feels “puffy and swollen” and this discomfort can impact the food choices she makes for the rest of the day, the way she speaks to the people she loves the most in the world and intimacy can fly out the window. That’s just the first half of the cycle!

Once ovulation occurs around mid-cycle, the majority of a woman’s progesterone is made by the corpus luteum, the crater that remains in the surface of the ovary after an egg has been released. On day 21 of the cycle, progesterone is supposed to peak, yet the most common test result I get back from laboratories is “<0.5”… in other words, the lab can’t find it… can’t find the hormone that is designed to help keep us calm, not anxious, not deeply sad and have our clothes continue to fit.

For too many women, estrogen is dominant (to progesterone) leading into the menstrual period and this is the typical hormonal imbalance that is the basis of PMS – heavy clotty painful periods, swollen tender breasts, and mood swings that can oscillate from intense irritability to immense sadness, sometimes in the same hour and often for reasons that cannot be identified! This can feel like chaos for a woman… and everyone around her.

I like to say this biochemical and emotional scenario is common but not normal. It doesn’t have to be this way. What if the symptoms your body gives you, what if the parts of your body that frustrate or sadden you, are simply messengers asking you to eat, drink, move, think, believe or perceive in a new way? It is time to see them as the gifts that they are. These symptoms can be wake up calls for women to make changes in their lives they may not otherwise make, enhancing their health, energy, vitality and greatness in the process.


Why do we do what we do when we know what we know?

So why do we do it? One reason is because we care so much for the people in our lives. On one level this way of living comes from such a beautiful place. It happens because we have beautiful hearts, but even deeper than that it happens because we made up a story a really long time ago that we aren’t enough the way we are; that we aren’t good enough, tall enough, slim enough, pretty enough, brainy enough, on time enough, that we’re just not enough the way that we are, so we spend our lives trying to please everyone in our realm, putting their needs ahead of our own. We rush around and do all we can to make sure that others love and appreciate us so that we never, ever have to feel rejected, ostracised, unlovable, criticised, yelled at, and like we’ve let others down.

It’s not just the physical health consequences that concern me for women. It’s that they live their lives so out of touch with their beautiful hearts, out of touch with how extraordinary they are and in the cloud of false belief that they aren’t enough.

It is important to realise that the way we eat, drink, move, think, believe and perceive impacts our need to rush. As a scientist and health professional I aim to help people live their lives with more PNS activation because this alone can have the most profound effect on health. From that place sex hormones are far easier to balance, liver function (detoxification processes) and digestion work closer to optimal so there’s far less bloating, and the thyroid works better which is also important for metabolic rate and the ability to burn body fat.

Bring awareness to why you do what you do and work out what lead you there. Awareness, rather than judgment of ourselves is the first step in this journey to retire from the rush. Please remember that life is precious, that you are precious and to treat yourself accordingly.

See Dr Libby’s TEDx Talk

I’m so excited to share with you that my TEDx talk has now gone live. Being invited to speak at TEDx was a dream that I was privileged to turn into a reality recently.

The speaking rules require you to deliver your “ideas worth spreading” in under 18 minutes so I poured my brain, heart and soul into coming up with a message that I hope can impact millions of people. Given my shortest seminar is usually 90 minutes, refining my message to be 18 minutes long was quite a challenge for me!

My mission is to ‘educate and inspire, enhancing people’s health and happiness, igniting a ripple effect that transforms the world’. I would like to invite you to watch my talk, titled ‘The pace of modern life verses our cavewoman biochemistry’.

If after watching the talk, you feel it contains a meaningful message worth spreading, I’d love you to share it with your friends, family and colleagues. I look forward to reading your feedback in the YouTube comments section, and watching the likes grow.

Thank you so much for your support and encouragement over the years. I learn so much from all of the people I come into contact with and am honoured to share this talk with you. Together let’s ignite that ripple effect of increased health and happiness in the world.

With Warmth
