• Turmeric is known for its numerous beneficial properties, making it a valuable ingredient in both cooking and medicine. One of the main substances found in turmeric is curcumin, which has powerful antioxidant and anti-inflammatory properties. This compound helps fight inflammation in the body and can significantly reduce the risk of chronic diseases.

  Furthermore, turmeric acts as a natural digestive aid, promoting healthy stomach and intestinal function. It also supports the immune system, helping the body resist infection and disease. Research shows that turmeric may have a positive effect on blood sugar levels, making it beneficial for people with diabetes.

  Furthermore, some studies point to curcumin's potential for supporting brain health, as it may help improve cognitive function and reduce the risk of neurodegenerative diseases. It's important to note that for maximum absorption of curcumin, it is recommended to combine turmeric with black pepper.

  Thus, turmeric is not only a delicious spice but also a true source of health, possessing numerous benefits for the body.

• Does it have healing qualities?
• The optimal amount of turmeric that can be consumed varies depending on the individual's characteristics and specific goals. Generally, it is recommended not to exceed a dose of 1-3 grams of turmeric powder per day to achieve its benefits. It is important to remember that excess consumption can lead to unwanted side effects. Before making any changes to your diet, especially if you have a chronic condition or are taking medications, you should consult with your doctor or nutritionist.
• In what situations can it negatively affect health?

Definition of curcumin and its difference from turmeric

Turmeric is a spice with a bright golden hue and a rich, spicy flavor. Turmeric contains over two hundred natural compounds, among which the most active are curcuminoids and polyphenols.

Curcumin is the key and most studied element of turmeric. It is responsible for the bright yellow hue of this spice and has many beneficial properties. Although curcumin makes up only 1–7% of turmeric's total weight, it is often used in its pure, concentrated form as a dietary supplement.

Healing Properties of Turmeric for the Body

One teaspoon of dried ground turmeric, weighing 3 grams, includes [4]:

Turmeric can be consumed in either fresh or ground form, with the differences in nutritional value being insignificant.

Most scientific studies focus on the activity of curcumin, making it difficult to clearly separate its properties from the health benefits of turmeric as a whole. Therefore, we will focus on the benefits of both turmeric and curcumin simultaneously.

So, let's consider five of the most significant benefits of turmeric.

Antioxidants play a vital role in protecting the body from the harmful effects of oxidative stress. Our bodies must maintain a balance between oxidation and its control mechanisms; otherwise, oxidative stress can develop. Excessive reactive oxygen species can damage cells, including their membranes, internal structures, and DNA. As a result, cells die faster, leading to accelerated aging and increasing the risk of chronic diseases.

Curcumin is one of the most effective antioxidants, surpassing vitamin E in its ability to scavenge reactive oxygen species. In addition, it helps maintain the functioning of the body's internal antioxidants.

Antioxidants are substances that play an important role in maintaining the health of the body. Their primary function is to neutralize free radicals—molecules that can cause oxidative stress, which can lead to cell damage and the development of various diseases.

Antioxidants are essential for the body because they help protect cells from environmental damage and reduce the risk of chronic diseases such as cardiovascular disease and cancer. They also help slow the aging process and support the immune system.

Antioxidants can be obtained from a variety of food sources. Fruits and vegetables are the richest sources, especially brightly colored ones such as berries, citrus fruits, spinach, and carrots. Nuts, seeds, green tea, and dark chocolate are also worth considering. It's important to include these foods in your diet to provide the body with the necessary protection and maintain overall health.

According to the Arthritis Foundation, taking 500 mg of curcumin extract twice daily may help reduce inflammation in patients suffering from rheumatoid arthritis and osteoarthritis.

Arthritis is a group of diseases characterized by inflammation of joint tissue. For example, rheumatoid arthritis is a consequence of an autoimmune disorder, while osteoarthritis occurs as a result of excessive stress on the joints, which leads to gradual wear and tear of cartilage. Regardless of what exactly causes arthritis, one thing is clear: inflammation in the joint tissues leads to the activation of immune cells, which release reactive oxygen species, which contribute to the destruction of joints.

Medications designed to combat arthritis reduce inflammation, which, in turn, helps reduce pain. Research by South Korean scientists has shown that turmeric may have similar properties. Taking 1,000 milligrams of turmeric extract for 2-3 months demonstrated results comparable to those of painkillers in relieving joint pain. Curcumin has a positive effect on brain health and on people engaged in mental activity. The Centre for Human Psychopharmacology at Swinburne University conducted a study comparing the effects of turmeric and a placebo on a group of participants aged 50 to 85. For 12 weeks, subjects received either a placebo or curcumin. The curcumin group experienced reduced fatigue, improved memory, and increased resilience to stress. Researchers continue to study turmeric's potential for weight loss. One proposed explanation is that curcumin promotes a faster metabolism, which means the body burns more calories at rest.

Curcumin helps increase insulin sensitivity, which means it improves the ability of cells to respond to this hormone and efficiently utilize glucose. This effect is thought to be related to turmeric's anti-inflammatory properties. The fewer inflammatory compounds in the body, the more effectively insulin functions.

Curcumin's anti-inflammatory properties may help improve fat metabolism. A small study found that taking 10 mg of curcumin daily for 30 days increased levels of "good cholesterol," known as high-density lipoprotein, and decreased levels of "bad cholesterol," known as low-density lipoprotein.

The World Journal of Gastroenterology classifies curcumin as a choleretic substance, promoting both the formation and excretion of bile. Metabolites of curcumin activate contractions of the gallbladder, thereby improving the digestion process.

Individual reactions to turmeric: reasons for the multifaceted effects

The effectiveness of curcumin contained in turmeric is inconsistent, since its bioavailability is extremely low; It is poorly absorbed, quickly metabolized and excreted from the body.

The most pronounced beneficial qualities of turmeric become noticeable when it is consumed together with black pepper. The latter's main component, piperine, can increase curcumin absorption by as much as 2000%. This is why curcumin is often found in combination with piperine in various dietary supplements.

Researchers are currently developing curcumin nanostructures capable of delivering significant doses of this compound and exerting therapeutic effects. Liposomes—small spherical structures composed of several layers of phospholipids—are used as curcumin carriers. Because their structure resembles the cell membrane, which contains similar phospholipids, liposomes readily bind to target cells and release their contents directly into their cytoplasm.

Curcumin as a Therapeutic Agent: Myth or Reality?

No, despite the fact that curcumin is highly reactive and actively interacts in the body, the exact molecular mechanisms of its action remain unclear and the subject of scientific debate. Therefore, mainstream medicine does not consider curcumin a drug. However, this does not prevent its use as a beneficial dietary supplement.

Dietary supplements (DS) are products intended to supplement the diet. They may contain vitamins, minerals, herbs, amino acids, and other components that are believed to help improve health or maintain certain body functions.

However, the question of their safety remains relevant. Unlike medications, dietary supplements do not always undergo rigorous clinical trials, which makes their quality and effectiveness sometimes questionable. Therefore, before starting to take any supplements, it is recommended to consult a doctor or qualified healthcare professional. It is important to remember that while dietary supplements can be beneficial, their improper use or excessive consumption can lead to undesirable health effects.

Optimal Dosage of Turmeric for Consumption

"There is no single accepted or recommended dose of turmeric for daily consumption," says Debbie Petipain, a registered dietitian representing the Academy of Nutrition and Dietetics.

There are recommendations regarding the safe dose of curcumin. According to the World Health Organization (WHO), the maximum tolerable intake is 3 milligrams of curcumin per kilogram of body weight per day. However, it is worth noting that these data are based on animal studies.

When should you avoid turmeric?

The US Food and Drug Administration (FDA) has designated curcuminoids as "generally recognized as safe" (GRAS), and clinical studies have confirmed the high tolerability and safety of curcumin, even when consumed in significant doses.

However, you should be careful and avoid using this spice in a number of situations:

• Allergic predisposition. In those prone to allergies, turmeric can cause itching and rashes on the skin.
• Pregnancy and lactation. Currently, there is insufficient data to definitively state the safety of turmeric supplements for pregnant and breastfeeding women. Therefore, it is recommended to refrain from using them.
• Gallbladder diseases. Turmeric can provoke contraction of the gallbladder, which can worsen the symptoms of gallstones.
• Iron deficiency anemia. Studies show that turmeric can interfere with the absorption of iron in the intestinal tract.
• Taking medications. Turmeric can increase the likelihood of bleeding when using anticoagulants [25]. In addition, this spice helps lower blood glucose levels, so if you use medications to control diabetes, it is important to discuss their dosage with your doctor [26].

Ground turmeric may contain trace amounts of lead, arsenic, cadmium, nickel, and other heavy metals. This contamination is particularly dangerous for certain groups of the population, including pregnant women, nursing mothers, children, and people with liver and kidney disease.

Frequent loose stools with a yellow tint may be observed for three days after you start using turmeric. This phenomenon is normal and should not be perceived as a negative symptom.

Aromatic dishes with the addition of turmeric

The most well-known dish that contains turmeric is curry. This sauce not only gives dishes a bright golden color but also imparts a unique aroma and flavor. Turmeric can also be used to create a variety of delicious drinks. Adding hot water to turmeric preserves all its valuable nutrients. The result is a rich and vibrant tea rich in antioxidants with the addition of turmeric.

Ingredients:

• One teaspoon of curcumin powder or a small piece of fresh turmeric root about 2.5 cm long, grated or thinly sliced.
• 1-2 cups of water;
• Optionally, you can add a small piece of ginger, a pinch of black pepper, and honey or lemon to taste.

How to make tea:

• Bring water to a boil in a saucepan.
• To the boiling water, add turmeric and ginger.
• Reduce heat and let the mixture simmer for about 10 minutes.
• Strain the tea to remove all solids.
• Add black pepper, honey, or lemon.
• You can add milk to your taste if desired.

Let the turmeric tea steep, then enjoy it warm.

Golden milk is a traditional drink from India that It's made by heating milk with turmeric and various spices. The most basic recipe uses ground turmeric, black pepper, and milk, but other ingredients can be added to enhance its nutritional value and flavor. It is believed that drinking this drink before bed helps you fall asleep faster and improves the quality of your sleep.

Registered nutritionist Nisha Melwani shares a recipe for golden milk [33]:

• In a small saucepan over low heat, combine one to two teaspoons of turmeric powder with one glass of warm milk and add a pinch of black pepper.
• To enhance the flavor, you can include various spices in the recipe, such as ginger, cinnamon, and cardamom, and add sweeteners of your choice, such as honey, maple syrup, or date syrup.
• Keep the mixture warm for ten minutes to allow the milk to absorb all the flavors and nutrients.
• Pour the golden milk into a cup and enjoy.

The nutritionist also recommends using low-fat milk for optimal results, as the fat helps the milk digest more effectively. absorption of curcumin.

Golden milk is traditionally made with cow's milk, but it is quite possible to replace it with unsweetened plant-based alternatives such as almond, oat, or soy milk.
