Organic Kale Powder: the underestimated ‘guardian’ of immunity | FocusHerb

Organic Kale Powder is a shining star in the trend of healthy eating. It is a horticultural variant of the Brassica species, a biennial herb native to the Mediterranean coast and now widely cultivated around the world. Kale plants are usually low, with closely spaced basal leaves in a distinctive rosette arrangement. The leaves are varied in form, including glossy, crinkled, lobed and wavy leaves. The outer leaves are broad and bright green, yellow-green or blue-green in colour, and the petioles are stout and winged, with the veins and petioles often appearing a light purple. The colours of the inner leaves are even more colourful, covering yellow, white, pink, red, rose red, purple red, greenish grey and a variety of miscellaneous colours, just like nature's carefully painted works of art, which also made it once widely planted in flowerbeds as an ornamental plant. 
In recent years, as people's attention to healthy diet continues to increase, kale with its high nutritional value, from ornamental plants successfully transformed into a highly sought-after health ingredients, in the field of healthy diet occupies an important place, by the many pursuit of high quality of life and healthy body loved by the people, became the new favourite on the table.

Nutrition Facts Revealed

The secret to Organic Kale Powder's reputation as a ‘superfood’ is hidden in its rich nutritional profile. From vitamins to minerals, dietary fibre to phytochemicals, each ingredient contributes something unique to human health. 
The vitamin family is huge in kale, and the vitamin C content is particularly impressive, with about 63mg of vitamin C per 100g of kale, even more than in many common citrus fruits. Vitamin C is a powerful antioxidant that not only helps protect the body from free radicals, but also plays a key role in collagen synthesis, helping to maintain healthy skin, blood vessels and bones. Vitamin K, which contains about 390 micrograms per 100 grams, is essential for healthy bone development and proper blood clotting, and promotes the deposition of calcium in the bones, increasing their strength and density. In addition, kale is also rich in vitamin A (in the form of β - carotene), per 100 grams of β - carotene contains up to 4368 micrograms, which can be converted into vitamin A in the body according to the need to play an important role in protecting the health of the eyes, can prevent night blindness and other eye diseases, but also maintain the normal metabolism of the skin and physiological functions of the skin, so that the skin to maintain smooth and delicate. It also maintains the normal metabolism and physiological functions of the skin, keeping the skin smooth and delicate. 
Kale also excels when it comes to minerals. It is rich in calcium, with about 66mg of calcium per 100g, which is not particularly high compared to traditional high-calcium foods such as milk, but it is a good source of calcium for vegetarians or people who are lactose intolerant, and helps maintain healthy bones and teeth. Iron is also a good source of iron, which provides the body with the raw materials needed to make haemoglobin, and can play a positive role in preventing iron deficiency anaemia, especially for women and children, for whom it is important to consume enough iron. Magnesium, potassium and other minerals in the kale also have a certain content, magnesium is involved in the activation of a variety of human enzymes, heart health, muscle function and the normal operation of the nervous system are of great significance; potassium helps to maintain the electrolyte balance in the body, regulate blood pressure, promote the normal beating of the heart, cardiovascular health play a protective role. 
Dietary fibre is also a nutritional highlight of kale, containing about 3.7 grams of dietary fibre per 100 grams. These dietary fibres are divided into soluble and insoluble, soluble dietary fibres can form a kind of viscous material in the intestinal tract to help reduce the absorption of cholesterol and regulate the level of blood glucose; insoluble dietary fibres are like the intestinal ‘cleaner’, which can increase the volume of fecal matter, promote peristalsis, prevent constipation, and reduce the risk of intestinal diseases. The risk of intestinal diseases is reduced. 
In addition to the common nutrients mentioned above, kale also contains a variety of unique phytochemicals such as flavonoids, sulphides, indole - 3 - methanol, etc . These substances have antioxidant, anti-inflammatory, antibacterial and other biological activities, which can help the body to resist various diseases. Among them, flavonoids have strong antioxidant ability, which can remove excessive free radicals in the body, reduce cell damage caused by oxidative stress, and lower the risk of cardiovascular disease and certain cancers; sulfides have a special odour and bioactivity, which not only enhance the body's immune system, but also positively promote the detoxification function of the liver; and indole-3-methanol can be converted into substances with anticancer activity, which can inhibit cancerous cells. Indole-3-methanol can be converted into an anticancer substance in the body that can inhibit the growth and spread of cancer cells, which is helpful in the prevention of many types of cancers such as breast cancer and prostate cancer.

An In-Depth Look at the Principles of Immune Enhancement

The key role of vitamin C

Vitamin C plays a crucial role in the immune-enhancing process of Organic Kale Powder. It acts as the immune system's ‘right hand man’ and promotes the production of white blood cells. As an important line of defence for the body's immune system, white blood cells are responsible for identifying and destroying pathogens, such as common cold and flu viruses and various bacteria. When the human body is attacked by pathogens, vitamin C can stimulate the activity of leukocytes, so that they can attack pathogens more quickly and effectively. 
As an example, some people increase their intake of vitamin C-rich foods, such as Organic Kale Powder, during the change of seasons and the high incidence of influenza, in order to enhance their immunity. According to relevant studies, people who regularly consume foods rich in vitamin C have a relatively lower chance of contracting the flu during the flu season, and even if they are infected, their symptoms are relatively mild and their recovery time is shorter. This demonstrates the effectiveness of vitamin C in boosting the immune system, and Organic Kale Powder, as a good source of vitamin C, provides a natural boost to our immune system. 

Antioxidants and Inflammation Regulation

Organic Kale Powder is rich in antioxidants such as flavonoids, vitamin C, vitamin E, and beta-carotene, which work in synergy to build a strong defence for the immune system. Free radicals, which are highly reactive molecules, are constantly generated during the body's metabolic process. When free radicals accumulate in the body, they act as ‘spoilers’, attacking cells and tissues, triggering oxidative stress, causing damage to the body and leading to inflammation. Antioxidants react with free radicals and stabilise them, thus scavenging them and reducing the damage caused by oxidative stress. 
There is a strong correlation between inflammation and immunity. A moderate inflammatory response is a normal defence mechanism of the body's immune system against invading pathogens, and it helps the body defend itself against germs. However, when the inflammatory response is out of control and persists in a state of chronic inflammation, it can negatively affect the immune system . For example, chronic inflammation may interfere with the normal functioning of immune cells, weakening the immune system's ability to recognise and eliminate pathogens, thus making the body more susceptible to disease . The antioxidants in Organic Kale Powder enhance immunity by modulating the inflammatory response, keeping inflammation in moderation and preventing it from damaging the immune system . For example, studies have found that people who regularly consume kale have relatively low levels of inflammatory markers, suggesting that their bodies are in a healthier inflammatory balance and that their immune systems are boosted accordingly. 

Dietary fibre and gut health

Dietary fibre plays a major role in the immune-enhancing process of Organic Kale Powder by promoting intestinal motility and improving the balance of intestinal flora. Dietary fibre acts as a ‘lubricant’ in the intestines, increasing the volume of faeces and making it easier to pass out of the body, thus effectively preventing constipation . At the same time, it can also stimulate intestinal peristalsis, so that the intestinal tract to maintain a good state of movement, to promote the digestion and absorption of food . 
The intestinal tract is known as the ‘second brain’ of the human body and is also the largest immune organ of the body, intestinal health is crucial for the enhancement of immunity . In the gut, trillions of microorganisms inhabit the intestinal tract, which make up the complex intestinal flora . These intestinal flora play a variety of important roles in maintaining human health, such as helping to digest food, synthesise vitamins, and defend against invading pathogens. Dietary fibre is precisely the ‘food’ for the beneficial intestinal bacteria, which can be fermented and utilised by beneficial bacteria in the intestinal tract such as bifidobacteria and lactobacilli to produce short-chain fatty acids and other beneficial substances . These short-chain fatty acids can not only provide energy for intestinal cells, promote the growth and repair of intestinal cells, but also regulate the pH value of the intestinal tract, inhibit the growth of harmful bacteria, and maintain the balance of intestinal flora . When the intestinal flora is in a balanced state, the barrier function of the intestinal tract is enhanced, which can effectively block the invasion of pathogens, and also activate the immune system, promote the production and activity of immune cells, thus enhancing the overall immunity. The rich dietary fibre in Organic Kale Powder provides sufficient nutrients for intestinal health, contributing to the balance of intestinal flora and thus laying a solid foundation for strengthening immunity.

Strong support from scientific research

Numerous scientific studies have provided solid evidence for the immune-boosting effects of Organic Kale Powder. A study published in the Journal of Nutrition delved into the effects of Organic Kale Powder on the human immune system. The researchers selected two groups of healthy volunteers, one as the experimental group, consumed a certain amount of Organic Kale Powder every day; the other group as a control group, a normal diet . After a period of follow-up observation, it was found that the number of leukocytes in the blood of the volunteers in the experimental group increased significantly, and the activity of leukocytes was also significantly enhanced . This indicates that the nutrients in Organic Kale Powder can effectively promote the production of leukocytes and enhance the immune function of leukocytes, thus improving the immunity of the human body. 
There is also a study on the elderly, due to the relatively weak immune system of the elderly, more vulnerable to disease attack. In the study, some of the elderly were asked to increase the intake of Organic Kale Powder in their daily diets, while others maintained their original dietary habits. The results showed that the elderly who consumed Organic Kale Powder were significantly less likely to be infected with influenza virus during the flu season, and even when they were infected, their symptoms were relatively mild and their recovery time was shorter. This proves that Organic Kale Powder has a significant effect in enhancing the immunity of the elderly.

Tips and Precautions

Although Organic Kale Powder is very nutritious and beneficial for strengthening the immune system, there are some tips and precautions to keep in mind when consuming it. 
When it comes to serving size, stick to the principle of moderation. Although it is rich in a variety of nutrients, excessive consumption may put a burden on the body. For example, although the dietary fibre in kale helps with intestinal motility, too much of it at one time may cause bloating, abdominal pain, diarrhoea and other indigestion symptoms. Generally speaking, adults can satisfy their nutritional needs by consuming about 100 - 150 grams of Organic Kale Powder per day. 
Special populations should consult their doctor before consuming Organic Kale Powder. For people with abnormal thyroid function, as kale is a cruciferous vegetable, it contains thioglycosides, which will be converted into thiocyanate in the body, and this substance may affect the absorption of iodine by the thyroid gland, thus interfering with the normal function of the thyroid gland. Therefore, patients with thyroid disease, especially those with hypothyroidism, need to strictly control the intake of kale . People with renal insufficiency should also be cautious, because kale is rich in potassium, and the kidneys are an important organ to regulate the balance of potassium in the body, when renal function is impaired, the ability of the kidneys to excrete potassium decreases, excessive intake of foods containing high potassium, such as kale, may lead to hyperkalaemia, which can seriously affect the normal function of the heart and nervous system. 
Extra care is also needed if you are taking certain medications. The chemicals in Organic Kale Powder may interact with some medications. For example, it may affect the efficacy of anticoagulant drugs because kale is rich in vitamin K, which plays a key role in blood clotting, and antagonises anticoagulant drugs. Therefore, people who are under medication should always consult their doctors before consuming Organic Kale Powder to find out if there are any interactions between food and medication, so as to avoid affecting the efficacy of the medication or triggering adverse reactions . 
In addition, when buying Organic Kale Powder, try to choose organic certified products, which are safer and healthier as they are grown without the use of chemical pesticides, fertilisers and growth regulators. When storing, it should be placed in a dry, well-ventilated place, avoiding direct sunlight, and preferably in the refrigerator freezer, which can prolong its freshness. Before consumption, it should be washed carefully to remove any impurities and microorganisms that may remain on the surface.
