Women’s Hormones and Gut Health: The Crucial Connection
Understanding how women’s hormones and gut health are connected is important for overall well-being. As a leading dietitian, Gillian Killiner emphasizes the importance of this connection. Hormones significantly influence gut health, and vice versa, making it vital to address both aspects for optimal health. The Role of Women’s Hormones in Gut Health Hormones are important chemicals that control many functions in women’s bodies, like metabolism, mood, and reproductive health. They are essential for keeping the body working properly. Estrogen, progesterone, and cortisol are important hormones for women that have a big impact on their bodies. Even small changes in hormones can cause many health problems like irregular periods, mood swings, and digestive issues. Maintaining hormonal homeostasis is therefore absolutely paramount for safeguarding women’s hormone cycle, overall health, wellbeing, and quality of life. Hormones play a key role in many important bodily functions, so it’s crucial for women to prioritize maintaining hormonal balance. So what do we need to consider…. Estrogen and Gut Health Estrogen, a key female sex hormone, exerts a profound influence on overall gut health. This important hormone helps shape the types of microorganisms in the gut, which are tiny organisms living in the digestive system. Estrogen helps protect the gut lining by keeping it strong and preventing harmful substances from entering the bloodstream. During menopause, lower estrogen levels can upset the balance in the gut, causing a condition called “leaky gut.” In this state, the gut barrier becomes more permeable, letting harmful substances pass through and enter the bloodstream. This permeability can lead to inflammation in the body. This inflammation can cause autoimmune disorders like inflammatory bowel disease (IBD), chronic fatigue, infertility, and other health issues. Understanding the importance of estrogen in maintaining gut health is crucial for women going through menopause. Taking steps to support gut health can help women stay healthy during this time of hormonal changes. Converesly when estrogen gets out of wack oestrogen dominance takes over. A healthy estrobolome helps maintain estrogen balance by regulating its levels in the body. Dysbiosis, or an imbalance in gut bacteria, can impair estrogen metabolism, leading to estrogen dominance or deficiency. This imbalance can contribute to conditions such as PMS, endometriosis, and polycystic ovary syndrome (PCOS). How does this occur? one group of offenders are Endocrine disruptors, such as environmental toxins. These can disrupt hormonal balance, potentially leading to estrogen dominance. Estrogen dominance can manifest in various symptoms, including menstrual irregularities, infertility, and weight gain. Gut health disruptions may exacerbate these symptoms, affecting overall well-being. Progesterone and Digestion Progesterone, another essential hormone, plays a pivotal role in regulating the menstrual cycle and sustaining pregnancy. Furthermore, this crucial hormone exerts a significant influence over gut motility. During the luteal phase of the menstrual cycle or pregnancy, imbalanced progesterone levels can slow down digestion. This can lead to symptoms such as bloating and constipation. These symptoms may be more severe if estrogen levels are also not balanced. Conversely, a low or diminished progesterone levels can trigger increased gut motility, consequently resulting in diarrhoea and discomfort. The balance of hormones like progesterone affects the digestive system. It’s important to keep hormone levels in check for good digestive health and overall wellbeing. Cortisol and Stress on Women’s Hormones Cortisol is a hormone that responds to stress in the body. It plays a big role in gut health through the gut-brain connection. Long-term stress can disrupt the balance of good bacteria in the gut. This can make it easier for harmful substances to pass through the gut lining. This stress-induced physiological response can significantly exacerbate the symptoms associated with irritable bowel syndrome (IBS) and other debilitating digestive disorders. The gut and brain are connected in a complex way. Changes in gut function can affect brain activity, and vice versa. Managing cortisol levels and stress is important for a healthy gut and reducing symptoms of conditions like IBS. Gut Health’s Impact on Hormonal Balance So how can your gut health impact on hormones? The gut microbiome is a complex system of trillions of bacteria, fungi, and other tiny organisms. It is increasingly seen as important for regulating hormones in the human body. A well-balanced, thriving gut microbiome can actively contribute to the harmonious regulation of our hormonal systems, helping to maintain optimal hormonal balance. On the other hand, an unhealthy gut can cause hormonal imbalances, showing how closely connected gut health is to hormone function. This growing understanding highlights the importance of nurturing a healthy gut microbiome as a means of supporting overall hormonal equilibrium and wellbeing. 7 Tips for Balancing Hormones and Improving Gut Health Eat a mix of fiber-rich foods, lean proteins, healthy fats, and fermented foods to help your gut stay healthy. Stay Hydrated: Adequate water intake is essential for digestion and overall health. Reduce stress and improve sleep by practicing techniques like yoga, meditation, and deep breathing exercises. This can help keep cortisol levels balanced. Get Regular Exercise: Physical activity promotes healthy digestion and hormone regulation. Think about probiotics: Probiotic supplements or foods like yogurt and kefir can help keep your gut healthy. However not maybe ideal if your gut health is not Limit Processed Foods and Sugar: These can disrupt gut health and contribute to hormonal imbalances. Fixing gut symptoms can help you eat more foods without issues. This can improve your hormonal health. Conclusion Wow, the intricate connection between women’s hormones and gut health is absolutely fascinating! The deep intertwining of these two vital aspects of our well-being is incredible. Understanding and addressing this powerful relationship can help women improve their health and quality of life. Isn’t that amazing? Gillian Killiner RD says it’s important to balance hormones and take care of your gut. This can be done through diet, lifestyle changes, and stress management. These factors are crucial for overall well-being. If you want to learn how to manage your hormones and gut health, it’s important to talk to a professional Dietitian.

Cholesterol: Dispelling the Myth and Unveiling the True Culprits of Poor Heart Health
For decades, cholesterol has been portrayed as the bad guy behind heart disease and poor health. However, it has also been known for many years that cholesterol and especially consuming cholesterol foods are not the true culprit. As a dietitian committed to promoting natural foods and supplements for optimal health, it is essential to explore the link between blood cholesterol, high-sugar diets, and processed seed oils among other contributing factors. This blog hopes to provide some debunking around the cholesterol myth and highlight the true contributors to heart disease and overall well-being. Understanding Cholesterol Cholesterol is a crucial substance that plays a vital role in various bodily functions. While it often gets a bad reputation, it is important to understand that cholesterol is essential for our overall health. Our liver is primarily responsible for producing the cholesterol needed by our body, while a smaller amount is obtained through the foods we eat. One genetic condition, Familial Hypercholesterolaemia (FH), is where there is a fault in one of the genes involved in removing cholesterol from the blood via your liver. It happens when you inherit a ‘faulty’ gene (also known as an ‘alteration’ or ‘mutation’) from one of your parents. Many people go instantly to a no fat diet and this is not the answer. Using a healthy diet with select medication is required still ensuring healthy fats are not completely avoided. The Flawed Cholesterol-Heart Disease Connection Numerous studies have questioned the long-held belief that consuming foods high in cholesterol directly leads to elevated blood cholesterol levels and an increased risk of heart disease. Research is shedding more and more light on this topic, suggesting that the impact of dietary cholesterol on blood cholesterol levels may be minimal when compared to other factors such as overall diet quality and lifestyle choices. This has implications for individuals looking to make informed decisions about their dietary choices and overall cardiovascular health and I am so delighted to see this out-dated belief being challenged. Cholesterol – Focus on the Real Culprits Heart disease and poor health are complex issues cannot be solely due to one factor, such as cholesterol. Rather than singling out cholesterol, it is important to address the role of other factors that are involved. These include the well-known like lack of exercise, unbalanced diet, obesity, stress, lack of sleep, alcohol, smoking, and others not so obvious like trans fats, medications, diabetes, hormone dyregulation, an underactive thyroid, poor kidney function. The two primary factors I wish to expand on in this blog are high-sugar diets and processed seed oils. Both of which are unnecessary but deeply ingrained in our eating habits worldwide and are related to heart disease and poor heart health when consumed in the modern diet. High-Sugar Diets and Heart Disease A high intake of added sugars, particularly refined sugars found in ultra-processed and processed foods and sugary beverages, leads to chronic inflammation and oxidative stress in the body. Dietary sugars mainly refer to fructose and glucose which are naturally present in fruits and some vegetables. The molecular formula you may remember from school biology is C6H12O6 and they are isomers of each other. Fructose and glucose are both considered to be sweet sugars, fructose is however the sweeter of the two but here is the important part – fructose is absorbed differently in the body. Unlike glucose, which is used by cells as an energy source, fructose is metabolized by the liver, where it promotes the synthesis of fat. High Fructose Corn Syrup (HFCS) is a common sweetener and preservative made from the simple sugars fructose and glucose. HCFS-55 and HCFS-42, are the most commonly utilized form that are used in beverages and baked goods. As you can gusess the numbers indicate the amounts so HCFS -55 contains 55% fructose and HCFS-42 and 42% fructose, respectively, with the remainder of the of the syrup being glucose. Since the 1970s, the amount of HFCS has increased in foods firstly in the USA but are now common within the “Western diet” consumed worldwide. The consumption of these types of processed sugars, particularly in sugary soft beverages (SSB), became a major contributor to sugar intake, and the correlation between sugar-sweetened beverages (SSB) and cardiometabolic diseases highlights the potential impact of fructose and glucose on our health. Cholesterol intake or Triglyceride Imbalances? So why worry? Well increased sugar consumption stimulates the liver to convert excess sugar into triglycerides, a type of fat, and it is elevated triglyceride levels in the blood that are strongly associated with an increased risk of heart disease. As highlighted the consumption of processed sugar has reached worrying levels in our modern diet and I see this in my everyday practice. Patients are providing food diaries doing their best to eat what they consider healthy for their heart; all low fat, and in fact they are more inflamed than ever with not paying attention to the processed sugars they are consuming. While natural sugar can provide a quick burst of energy and is fine as part of a balanced intake, excessive intake can have detrimental effects on our health. As mentioned elevated levels of triglycerides in the blood have been identified as a significant risk factor for heart disease. When triglyceride levels rise above normal limits, it can lead to plaque buildup in the arteries, increasing the chances of heart disease and related complications. I explain and teach this to my patients. It is crucial for individuals to monitor and decrease their sugar intake, they are also required to check blood levels and maintain healthy triglyceride levels, this will reduce their risk of heart disease and other inflammatory conditions. Processed Seed Oils and Heart Disease So what about seed oils? The imbalance of omega-6 and omega-3 fatty acids is a common dietary concern. Omega-6 and omega-3 fatty acids are both essential fats that our bodies need for various functions, such as proper brain function, healthy skin, and the regulation of inflammation. However, in today’s Western diet, the ratio
The Negative Impact of Ultra-Processed Foods on Your Health
Ultra-processed foods and what you need to know. In today’s fast-paced world, convenience often takes precedence over nutrition and that happens to us all. Unfortunaltey ultra-processed foods have become a staple in many people’s diets, offering quick and easy solutions for busy lifestyles. These foods can have detrimental effects on our health and well-being. As a dietitian with 26 years of experience, I have witnessed the growing consumption of ultra-processed foods and its impact on individuals. In this blog, we will explore the negatives of ultra-processed foods and understand why they should be minimized in our diets. Ultra-Processed foods – what are they? The NOVA food classification system, developed by researchers from University of São Paulo in Brazil, is where the phrase ‘ultra-processed foods’ originates from. The food products are classified into four groups depending on the extent of processing they have undergone during their manufacturing: Unprocessed or minimally processed foods are those that have undergone minimal or no alteration and contain no added ingredients. This includes fruits, vegetables, milk, fish, pulses, eggs, nuts and seeds in their natural state. 2. Processed ingredients Processed ingredients are used to enhance the flavour of certain foods, such as salt, sugar and oils. These ingredients are usually not consumed by themselves, but rather combined with other foods for added flavour. 3. Processed foods Processed foods are food items which are derived from groups 1 and 2, and modified in a way that one can replicate at home. Examples of such foods include making jams, pickles, canned fruits, veggies, making breads, cheeses. 4. Ultra-Processed foods Ultra-processed foods usually contain more than five components and ingredients that aren’t common in home cooking. These can include preservatives, emulsifiers, sweeteners, synthetic colours & flavours. Due to their additives, these food items are able to maintain their shelf life for an extended period of time. Examples of Ultra-Processed Foods Ultra-processed foods include ham, sausages, frozen waffles, nuggets, crisps, pizza, mass-produced bread, breakfast cereals, biscuits, carbonated drinks, fruit-flavoured yogurts, instant soups, icecreams and frozen desserts Unprocessed or minimally processed foods Fruit, vegetables, eggs, meat and grains. Processed culinary ingredients Sugar, salt, butter, lard, oils, vinegar Processed foods Freshly made, unpackaged bread, tinned fruits and vegetables, salted nuts, ham, bacon, tinned fish and cheese So why worry about Ultra-Processed Foods? Research on Ultra-Processed Foods Studies from the University of Sao Paulo in Brazil have found that excessive UPF intake (more than 56.8 per cent of the diet) increases the risk of type 2 diabetes, cardiovascular disease and cancer. In 2019, a study published in The BMJ found that people who ate a lot of UPFs (more than four servings a day) were at a 62 per cent greater risk of premature death from all causes than those with a low consumption. For each individual serving of UPF, the risk of death increased by 18 per cent. Conclusion While ultra-processed foods offer convenience and ease, it is important to recognize their negative impact on our health. As a dietitian, I encourage individuals to prioritize whole, minimally processed foods in their diets. By focusing on fresh fruits, vegetables, lean proteins, whole grains, and healthy fats, we can optimize our nutrient intake, support overall well-being, and reduce the risk of chronic diseases. Remember, small changes in our dietary choices can have a significant impact on our health in the long run. So, what to do next or for anything else..

What You Need to Know About Probiotics and Their Health Benefits
What are Probiotics and What Makes them so Beneficial? As we are still in the awareness month of gut health I felt it may be helpful to focus on an area that many people want to know more about for improving their gut; Probiotics. Probiotics have been around since ancient times when cheese and fermented products were popular among the Greeks and Romans. They even encouraged each other to consume these for the potential health benefits. The word “probiotic” comes from the Greek word for “for life.” Jump to 1905, a Bulgarian physician and microbiologist Stamen Grigorov identified the first recorded probiotic, Lactobacillus bulgaricus, in Bulgarian yoghurt. This discovery was groundbreaking and has led to further research into the potential of probiotics for many years. Today, probiotics are widely used in healthcare and nutrition as a natural way to improve digestive health and overall well-being. So what are they? Probiotics are live microorganisms that have been researched and proven to provide health benefits when consumed from suitable sources in adequate amounts. They are commonly found naturally in food sources often fermented such as yoghurt, miso, tempeh, sauerkraut and cheeses. In recent years this can also be taken as a supplement and due to modern manufacturing a mass market of choice has “mushroomed” onto the probiotic shelves. Probiotics work by introducing beneficial bacteria into the gut microbiome which helps to maintain a healthy balance of microorganisms. This balance is important for proper digestion, nutrient absorption, and immune system functioning. Research has shown that probiotics can help to reduce inflammation, improve digestive health, and boost the immune system. Additionally, probiotics may also help to reduce symptoms of certain diseases such as irritable bowel syndrome (IBS) and inflammatory bowel disease (IBD). Exploring the Different Sources of Probiotics and How to Properly Integrate Them Into Your Diet We know probiotics are found naturally in certain foods, such as yoghurt, sauerkraut and miso. But as mentioned they can also be taken as supplements in the form of liquids, pills or powders and even research has been carried out intranasally. I can’t cover them all as you would be really bored still reading in a few hours time! Suffice to say there are so many to choose from I often wonder is this more to do with confusing the consumer and encouraging them to keep buying new ones, and thus clever marketing, more money spent from repeat purchases. I really hope it is that we are just really lucky that the manufacturers are improving therapeutic doses, strains and delivery methods for all ages and stages of life. Most common types of probiotics Lactobacillus (Lactobacillus acidophilus) – This strain helps maintain a healthy balance between good and bad bacteria in your intestines. It’s also thought to help prevent diarrhoea caused by antibiotics.Bifidobacterium (Bifidobacterium lactis) – This strain helps improve lactose intolerance, boost immunity, reduce inflammation throughout the body (including in joints), help regulate blood sugar levels after eating carbohydrates like bread and pastas–and even reduce symptoms associated with irritable bowel syndrome (IBS). Just because they are common and frequently recommended in health food stores they are not always the best choice for many. Probiotics for Specific Conditions Probiotics are a good choice for anyone who wants to improve their health. They can help with digestion, immune function and even weight loss. But there are some specific conditions where probiotics are useful: Irritable Bowel Syndrome (IBS). This condition affects the colon or large intestine. It causes abdominal pain and bloating that may be accompanied by diarrhoea or constipation. Many people with IBS also experience gas and other symptoms like nausea or vomiting after eating certain foods. Studies have shown that taking certain probiotics while addressing the diet can help relieve these symptoms because they help balance out the bacteria in your gut–a process called “gut dysbiosis.” Our gut health programmes are uniquely designed for each individual to ensure probiotics are selected based on your specific requirements. Diabetes Type 2 prevention/treatment: Research has shown that taking certain strains of Lactobacillus rhamnosus GG (LGG) over time can reduce blood sugar levels in people who have prediabetes or type 2 diabetes mellitus (DM2). In one study published in Diabetes Care journal found that supplementing with LGG lowered fasting blood glucose levels by almost 10 percent compared to those taking placebo pills over six weeks period. Weight loss: Another study published in Obesity Reviews journal found supplementing with Bifidobacterium longum subspecies infantis helped reduce body fat percentage while increasing lean muscle mass. A snapshot of thousands of probiotics available. What Are Some Potential Side Effects or Risks Associated With Taking Probiotics? While the potential benefits of probiotics are well-known, there are also potential risks associated with taking them. These risks could include allergic reactions, interactions with medications, and changes in the balance of good and bad bacteria in your gut. Certain people may be at higher risk for adverse events due to various conditions. These include people with immunodeficiency, short bowel syndrome, central venous catheters, cardiac valve disease, and premature infants. These individuals may be more vulnerable to certain infections or other medical issues that can result from their medical condition. It is important to understand these risks before taking probiotics so that you can make an informed decision about whether or not to take them and discuss any potential risks with your healthcare provider. I think it is important to point out here that if your gut is doing as it should you have no unpleasant GI or health issues then leave it to get on doing what it does best and don’t interfere! Prebiotics and Synbiotics You may have heard of Prebiotics and synbiotics. These are dietary supplements that help to promote the growth of beneficial bacteria by providing food for the probiotic organisms, thus encouraging them to multiply.Prebiotics are non-digestible fibres that pass through your digestive system unchanged, but they act as fertilizer for probiotic bacteria in your intestines. They’re found naturally in foods like bananas, onions and
Sports Nutrition looking forward
Sports Nutrition The field of sports nutrition is vast. Personalised performance nutrition can be super confusing with so many options to choose from. This blog dives into the following: The basics for you to be optimal What is the ultimate approach Research and the future in sports nutrition It can be all too easy to get it wrong or spend a fortune on a quick fix, or several! I see this every day in my clinic and also when I provide nutritional advice to followers on my fitness friend Caroline Girvan’s Facebook page in my Sunday live 1-hour session. As I have been involved in the world of Nutrition and health for over 25 yrs, including successfully working with athletes for the commonwealth games and Olympics, I love looking forward to what new ideas are ahead. Sports Nutrition – First things first Some background advice on getting you optimized! No point in not having the basics nailed….So. Know that you have to adopt a balanced real food approach that is nutrient-rich, otherwise, you will be disappointed with the amount of training, supplements or protein powder you pack in. These alone will not fix your physique or do anything for your health. 80% of success IS nutrition but the biggest part of this is consistency – whether it is counting macros, intermittent fasting, keto, the cabbage soup or Atkins these are all names of various dietary restrictions either by changing timings, altering nutrient intake e.g. fats or increasing fluids to reduce hunger etc but all in all they point to a kcal deficit to be successful. Are they successful – Sadly not all, and if they are they are often short-lived. I see many many hundreds of desperately miserable people doing everything they can to follow these restrictions. They may start well and see some changes but when something is too difficult, things slip and the feeling of failure can occur. I am firmly against this as Yo-Yo -dieting decreases energy expenditure, increases energy intake, and impairs brain-periphery communication. The Ultimate sports nutrition approach What many people HATE me telling them AND what works for the majority for the longterm is. Clever intuitive eating It is important to get the right mindset for this. You need to know that your body is not determined by numbers but by genetics, emotions, your food and life choices and all these interact with your overall diet and health. Bizarrely the belief that “no pain no gain” and a strict impossible plan is the answer, pushing the responsibility to someone else -and how many times do I hear the list of people that one person has taken a plan from and when it doesn’t work – it all stops and food becomes the comforter again. It’s true if you are totally confused by the past 30 yrs of inaccurate nutritional info, being able to choose your own nutrient-rich meals, snacks, fluids, party foods etc that are not on a strict plan can be overwhelming. If this is you then it may be worth working with someone (a nutrition expert) for a while, just to make sure you know what is necessary for you and you are able to enjoy it for the long term. That’s what we love and are experts in! Training to see ripped muscles takes far longer for many than they anticipate. As a beginner hypertrophy (building muscle) can be more difficult to achieve as the body is making neural adaptations. Progress and increasing strength allows for muscular growth but it does take time and patience. And finally – sufficient fluid intake and the types consumed are definitely overlooked. Fluid and enough fluid is critical to prevent dehydration, overheating causing confusion, low energy, and mood change, and also if ongoing can link to constipation and kidney stones. The Future of Sports Nutrition Research So what’s out there? It’s always a buzz to know brand-new areas are emerging with exciting products. Companies are more and more using science to optimize performance and especially important post-COVID with the resurgence in exercise, the gym and the importance of getting and staying healthy. Muscle Mass Everyone wants to build muscle right? Well, when I was starting out 25yrs ago that was not the case and it used to be for a few men in the gym and for really beefing up it was just a select few bodybuilders in competitions! Now we know that building muscle at all stages of life is mega important. Research into the physiology of improving muscle mass and strength is massive! While protein is the most important in terms of dietary supplementation, other researched ingredients include nitrogen oxides, nitrates, and creatine and these are used by millions daily. Carnosine and beta-alanine are also on the radar in muscle physiology research and may certainly be in some of your cupboards already! Carnosine is a naturally forming dipeptide (two linking amino acids beta-alanine and histidine) specifically found in the tissues of the body when they are active. Carnosine is also located in the heart, brain, and other parts of the body and is known to improve muscle strength and performance during exercise. Beta-alanine is a naturally occurring amino acid that supports the synthesis of muscle carnosine in the body. It is known to delay the onset of muscle fatigue and failure and is found in foods such as certain meat turkey, chicken, beef, pork and fish. It combines with the amino acid histidine to form the dipeptide called carnosine. This helps delay the onset of lactic acid and muscle fatigue and failure while building endurance and improving recovery. Hydration We know water is the best fluid to drink before exercise. Drinking 2-3 litres per day depending on your requirements is perfect especially if your activity is less than one hour. However, if you exercise for longer an isotonic sports drink with carbohydrates and sodium, and possibly potassium, calcium, and magnesium before and during exercise can be beneficial. There are gazillions out there
