Essential in the House to Boost Your Immunity This Cold & Flu Season
As flu season descends upon us once again, the familiar advice to get a flu shot is being touted by health agencies. However, vaccination may not be the most effective method for preventing illness during this time of year. Here in Northern Thailand, where winter has arrived and temperatures have dropped to a cool 23°C, the locals have a different approach to staying healthy. Unlike in other regions where flu shots are common practice, people in this area rely on the power of nutrition to boost their immune systems.
By consuming a diet rich in immune-boosting nutrients found in whole, healthy foods, people can better protect themselves against illness. With a range of easily accessible ingredients, you can support your immune function and keep yourself in optimal health throughout flu season. Whether you already have these items in your pantry or need to stock up, now is the perfect time to start incorporating these key foods into your daily meals.
A Small Bulb of Garlic Provides Big Benefits
Garlic has been revered for its culinary and medicinal benefits throughout history, as evidenced by its presence in ancient Chinese, Egyptian, Greek, Indian, and Roman medical texts. This pungent food offers a multitude of advantages, thanks to its anti-inflammatory, anticancer, and antimicrobial properties. Packed with bioactive compounds such as saponins, phenolics, and organic sulphides, garlic's sulphur-containing compounds like allicin, alliin, ajoene, and allyl propyl disulphide also play a significant role in its health benefits, particularly in fighting colds and the flu. Garlic's organosulphur compounds have been shown to help maintain immune system balance by positively influencing immune cell activity, including the regulation of cytokine levels and expression. This mechanism likely contributes to garlic's effectiveness in treating infections and tumours. By activating certain chemicals within the immune system, Garlic aids in the elimination of inflammatory cells and combats bacteria and viruses. One of Garlic's standout features is its impressive shelf life. An unpeeled head of Garlic can remain fresh for up to six months when stored in a cool, dry, well-ventilated, dark place at room temperature. However, peeled Garlic tends to degrade more quickly, so it is recommended to use it promptly. It's important to note that Garlic's beneficial compounds are sensitive to heat, which is why consuming raw, chopped garlic is ideal for maximising its immune-boosting effects (chopping or crushing enhances the allicin content). If the strong taste of raw Garlic is too intense for you, allowing the chopped garlic to sit for 15 minutes before cooking can help mellow the flavour while preserving its health benefits.
Raw Manuka Honey - A Powerful Alternative to Antibiotics for Respiratory Tract Infections
Manuka Honey, derived from the nectar of the manuka plant (Leptospermum) native to Australia and New Zealand, is renowned for its remarkable medicinal properties, particularly in wound healing. This unique honey is distinguished by its potent antimicrobial qualities, primarily attributed to dihydroxyacetone, a compound that leads to the formation of methylglyoxal (MGO). MGO is the powerhouse behind many of Manuka Honey's health benefits, including its ability to combat antibiotic-resistant respiratory infections. A systematic review and meta-analysis published in BMJ Evidence-Based Medicine highlighted Manuka Honey's efficacy in treating upper respiratory tract infections (URTIs), commonly known as the cold. The research demonstrated that Manuka Honey not only alleviated symptoms but also reduced the severity and frequency of coughs, proving to be more effective than conventional treatments. This natural remedy offers an accessible and cost-effective alternative to antibiotics, making it a valuable ally in the fight against antimicrobial resistance. However, further high-quality, placebo-controlled trials are necessary to fully validate these findings. It's essential to ensure that the Manuka Honey you choose is pure and free from contaminants. When stored properly, genuine, unadulterated Manuka Honey can last for years without spoiling. Be cautious, though; the processed honey commonly found in grocery stores is often mixed with corn syrup and lacks the health benefits of authentic Manuka Honey. Choose wisely for your health!
The Anti-Inflammatory Benefits of Ginger's Bioactive Compounds
Ginger, much like garlic, is a versatile and aromatic addition to your favourite dishes, imparting a distinct flavour profile. Not only can Ginger spice up your meals, but it can also be enjoyed as a soothing and fragrant tea, perfect for warming up during cold winter days. What sets Ginger apart is its impressive array of health benefits. It is renowned for its anti-inflammatory, antioxidant, and immunomodulatory properties, making it a powerhouse in promoting overall wellness. The warming effects of Ginger tea can help combat or alleviate a sore throat, particularly during the colder months. A study published in Frontiers in Nutrition highlights the various compounds in Ginger, such as gingerol, shogaol, zingerone, and paradol that contribute to its health benefits. These bioactive compounds work to inhibit pro-inflammatory responses, boost levels of anti-inflammatory cytokines, and enhance signaling pathways that help prevent inflammation. Furthermore, the antioxidant properties of Ginger play a crucial role in improving oxidative stress tolerance by neutralising harmful free radicals and enhancing antioxidant enzymes and capacity. Gingerol, the primary bioactive compound in ginger, has been shown to protect against viral and bacterial infections, including those associated with oral health and respiratory illnesses. To incorporate Ginger into your daily routine, simply peel the skin with a spoon and slice or grate it for use in smoothies, soups, or broth. For a fragrant tea, steep ginger slices in hot water, or use Organic Ginger Powder for convenience. To keep Ginger fresh, store it unpeeled at room temperature for up to three weeks or in the fridge for up to a month. Overall, Ginger is not just a flavourful ingredient in cooking but also a powerful ally in promoting health and well-being.
Hot Chilli Peppers Aid in Clearing Congestion
My love for Chilli Peppers is undeniable. They are a staple ingredient in every dish we prepare, regardless of the season. Have you ever noticed that eating spicy foods like Chilli Peppers can sometimes make your nose run? This reaction is due to capsaicin, a bioactive compound responsible for the fiery heat found in these foods. Surprisingly, this runny nose effect can actually be beneficial when you're feeling under the weather, as capsaicin has the ability to thin out mucus, making it a less hospitable environment for viruses and bacteria to thrive. But the advantages of Chilli Peppers don't stop there. These fiery little fruits are packed with vitamin C, often even more than oranges. For example, just a 4-ounce serving of raw green bell pepper contains 80 mg of vitamin C, while the same amount of yellow, red, or orange bell pepper provides even higher amounts. Varieties like serrano, jalapeno, and poblano peppers offer a different flavour profile for you to experiment with in the kitchen. Storing Chilli Peppers in the fridge can keep them fresh for up to a year, and freezing them can extend their life even further. Their versatility allows them to enhance a wide range of dishes with a mild, yet satisfyingly spicy kick. However, as with many things, moderation is key. Consuming too much capsaicin can lead to unpleasant side effects such as diarrhoea, nausea, vomiting, and a burning sensation in the gastrointestinal tract. So while Chilli Peppers can add a fiery flavour to your meals and provide valuable health benefits, it's important to enjoy them in moderation.
Bolster Your Immune System with White Tea or Turmeric
Ensuring you stay properly hydrated is crucial for maintaining a strong and healthy immune system, and luckily, there are plenty of delicious and nutritious beverages to choose from. Among my top picks for immune-boosting drinks are Turmeric Tea and White Tea, especially ideal during the colder months as they provide warmth and an abundance of antioxidants. Turmeric, a spice closely related to ginger, contains curcumin as its active compound, known for its powerful immune-boosting properties. The anti-inflammatory and antioxidant effects of curcumin have been well-documented, with recent studies also highlighting its immunomodulatory effects. Research conducted in Japan revealed that taking 150 milligrams of curcumin daily for 12 weeks helped shorten the duration of cold symptoms in healthy adults. In particular, it was found that curcumin consumption could reduce sneezing, nasal discharge, blocked nose, and coughing by significant margins. On the other hand, White Tea, derived from the Camellia sinensis plant, is rich in beneficial polyphenols such as catechins like EGCG, known for their antioxidant and anti-inflammatory properties. These compounds not only assist in improving immune function but also have positive effects on various physiological processes. Different compounds found in White Tea interact with immune cells in different ways, leading to diverse effects on the immune system. Research suggests that White Tea may have greater immunomodulatory potential due to the synergistic effects of its various compounds on innate and adaptive immune responses. Enhancing the benefits of White Tea can be achieved by adding a squeeze of lemon juice, as the vitamin C content helps increase the body's absorption of catechins. For optimal results, opt for loose-leaf green tea over tea bags, as many commercially available tea bags contain toxins and microplastics that can negatively impact your health. By incorporating Organic Turmeric Tea and White Tea into your daily routine, you can not only stay hydrated but also support your immune system with a powerful boost.
