Health Benefits Of Turmeric: All You Need to Know

Turmeric is a well-known culinary spice across the world as it is incorporated in a variety of cuisines in different ways. Turmeric or curcumin is used widely in soups, teas, curries, cakes, and many other dishes for its color, flavor and antimicrobial properties. It belongs to the ginger family, and it is becoming a popular spice not only for its taste but also for its medicinal and healing properties. In this article, we will explore the health benefits of turmeric and its role in improving or healing lifestyle related diseases.

Consumption of curcumin through food does not produce evident results as compared to supplemental intake. Mostly when turmeric is taken with food, the strength of the total amount gets distributed, reducing it to a lower dose not sufficient enough for studying its significance. So, multiple studies have been conducted through clinical trials to confirm the therapeutic properties of different dosages, ranging from 500mg to 2g tablets.

Antioxidant and Anti-Inflammatory Effects

Curcumin has shown evidence in studies that it has a potential effect on reversing the oxidative stress created within the body. Oxidative stress is often associated with lifestyle changes like smoking, alcohol, high sugar intake, and consumption of processed foods. Its association has also been linked to many inflammatory conditions and diseases like diabetes, arthritis, psoriasis, Alzheimer’s disease, and cardiovascular problems. Curcumin aids in reducing oxidative stress by eradicating free radicals and improves inflammatory conditions by restricting the activity of enzymes which are responsible for inflammation. Also, curcumin has shown evidence for its anticancer effects by deactivating gene products that are responsible for causing cancer.

Pain Management

Several studies have shown that curcumin supplements have beneficial effects in arthritic pain management similar to ibuprofen; stomach irritation is a common side effect caused by traditional pain management drugs like these, but curcumin has an added advantage of providing relief without any harmful side effects. However, when curcumin is consumed in excess amounts, it can cause stomach issues like nausea, vomiting or diarrhea. A clinical study with arthritis patients revealed that pain and inflammation related symptoms significantly improved with curcumin supplements, similar to the effect seen with regular pain killers.

Digestive Health

When taken in the right quantities, curcumin has numerous beneficial effects on digestive health. It helps alleviate symptoms like gas and bloating and helps maintain/facilitate normal bowel movements. It restores bowel function by killing bad bacteria and facilitating the growth of good bacteria in the stomach. In addition to this, people suffering from stomach ulcers and inflammatory disorders like Crohn’s disease, irritable bowel disease, and peptic ulcer can potentially benefit from taking curcumin supplements. Cardiovascular health is also positively impacted through oral consumption as it helps improve blood circulation and reduces cholesterol gallstone formation.

Other Health Benefits

Curcumin has proved to be effective in maintaining  and improving cognitive health, attention and memory in healthy individuals. It helps reduce bad cholesterol levels and is believed to be a supportive health supplement in people who wish to maintain healthy weight with diet management, without any strenuous exercise. On the other hand, turmeric aids in alleviating muscle soreness and inflammation caused due to exercise and also helps in boosting recovery and performance. In animal studies, when pregnant rats were treated with curcumin extracts, their offspring showed results of increased brain cell development, improved learning capabilities and memory. In humans, to study the nature of curcumin induced cognitive benefits, further research studies are required as there are not enough studies to claim the same cognitive benefits as seen in rats.

Safety Considerations

Turmeric is generally recommended to be safe for consumption by European and United States (FDA) food authorities. The JECFA (The Joint United Nations and World Health Organization Expert Committee on Food Additives) and European food safety authorities suggest an allowable daily intake value of 0–3 mg/kg body weight. Usually, food items and beverages with added curcumin are considered safer than tablets/capsules because the quantity of consumption with foods is comparatively lower to produce significant side effects.

However, it is not advisable to overindulge in consuming turmeric in any form for health benefits, other than those prescribed by your healthcare provider. Potential ill effects of overdosage can include headache, skin rash, upset stomach, vomiting and diarrhea.

Women who are pregnant or expecting pregnancy should refrain from taking this supplement as it may over stimulate the uterus and lead to complications in pregnancy.

In some cases, excessive or prolonged intake of curcumin has shown to cause serious liver injury. There have been several instances of jaundice and liver damage with this supplement, and it is one of the leading causes of herbal-related liver injury in the United States. Rarely, in severe cases of injury, it may even lead to death or need for liver transplantation. So, one must always be mindful of their health considerations and consider talking to a healthcare expert before deciding whether curcumin supplements are safe for them.
