Ways that Turmeric Fights Cancer and many other Diseases Turmeric may be the most effective nutritional supplement in existence.
Many high quality studies show that it has major benefits for your body and brain.
Here are the top 10 evidence-based health benefits of turmeric.
1. Turmeric Contains Bioactive Compounds With Powerful Medicinal Properties
Turmeric is the spice that gives curry its yellow color.
It has been used in India for thousands of years as a spice and medicinal herb.
Recently, science has started to back up what the Indians have known for a long time… it really does contain compounds with medicinal properties .
These compounds are called curcuminoids, the most important of which is curcumin.
Curcumin is the main active ingredient in turmeric. It has powerful anti-inflammatory effects and is a very strong antioxidant.
However, the curcumin content of turmeric is not that high… it’s around 3%, by weight .
Most of the studies on this herb are using turmeric extracts that contain mostly curcumin itself, with dosages usually exceeding 1 gram per day. It would be very difficult to reach these levels just using turmeric in your foods.
Therefore, if you want to experience the full effects, then you need to take a turmeric extract that contains significant amounts of curcumin.
Unfortunately, curcumin is poorly absorbed into the bloodstream. It helps to consume black pepper with it, which contains piperine… a natural substance that enhances the absorption of curcumin by 2000% .
I personally prefer to swallow a few whole peppercorns along with my curcumin supplement, to get that piperine to enhance absorption.
Curcumin is also fat soluble, so it may be a good idea to take it with a fatty meal.
2. Curcumin is a Potent, 100% Natural Anti-Inflammatory Compound
Inflammation is incredibly important.
It helps the body fight foreign invaders and also has a role in repairing damaged tissues.
Without inflammation, pathogens like bacteria and fungi could easily take over our bodies and kill us.
Although acute (short-term) inflammation is beneficial, it can become a major problem when it is chronic (long-term) and inappropriately deployed against the body’s own tissues.
It is now believed that chronic, low-level inflammation plays a major role in almost every chronic, Western disease. This includes heart disease, cancer, metabolic syndrome, Alzheimer’s and various degenerative conditions.
Therefore, anything that can help fight chronic, low-level inflammation is of potential importance in preventing and even treating these diseases.
It turns out that curcumin is strongly anti-inflammatory, it is so powerful that it matches the effectiveness of some anti-inflammatory drugs .
Curcumin actually targets multiple steps in the inflammatory pathway, at the molecular level.
Curcumin blocks NF-kB, a molecule that travels into the nuclei of cells and turns on various genes related to inflammation. NF-kB is believed to play a major role in many chronic diseases .
Without getting into the gory details (inflammation is extremely complicated), the key takeaway here is that curcumin is a highly bioactive substance that fights inflammation at the molecular level.
In several studies, its potency has compared favorably to anti-inflammatory pharmaceutical drugs… except without the side effects.
3. Turmeric Dramatically Increases The Antioxidant Capacity of The Body
Oxidative damage is believed to be one of the mechanisms behind ageing and many diseases.
It involves free radicals, highly reactive molecules with unpaired electrons.
Free radicals tend to react with important organic substances, such as fatty acids, proteins or DNA.
The main reason antioxidants are so beneficial, is that they protect our bodies from free radicals and oxidative damage.
Turmeric happens to contain potent antioxidants. The most important antioxidant in it is curcumin itself.
Curcumin can scavenge and neutralize free radicals on its own, due to its chemical structure.
But curcumin also boosts the activity of the body’s own antioxidant enzymes.
In that way, curcumin delivers a one-two punch against oxidative damage. It blocks free radicals directly, then stimulates the body’s own antioxidant mechanisms.
4. Curcumin Boosts Brain-Derived Neurotrophic Factor, Linked to Improved Brain Function and a Lower Risk of Brain Diseases
Back in the day, it was believed that neurons weren’t able to divide and multiply after early childhood.
However, it is now known that this does happen.
The neurons are capable of forming new connections (called synapses), but in certain areas of the brain, they can also multiply and increase in number.
One of the main drivers of this process is Brain-Derived Neurotrophic Factor (BDNF), which is a type of growth hormone that functions in the brain.
Many common brain disorders have been linked to decreased levels of BDNF. This includes depression and Alzheimer’s disease .
Interestingly, curcumin can increase blood and brain levels of BDNF .
By doing this, it may be effective at delaying or even reversing many brain diseases and age-related decreases in brain function .
There is also the possibility that it could help improve memory and make you smarter. Makes sense given its effects on BDNF levels, but this definitely needs to be tested in human controlled trials .
5. Curcumin Leads to Various Improvements That Should Lower Your Risk of Heart Disease
Heart disease is the biggest killer in the world .
It has been intensively studied for many decades and researchers have learned a lot about how it happens.
It turns out that heart disease is incredibly complicated and there are various processes that contribute to it.
Curcumin has been shown to be of use in reversing many steps in the pathological process of heart disease .
Perhaps the main benefit of curcumin when it comes to heart disease, is improving the function of the endothelium, which is the lining of the blood vessels.
It is well known that endothelial dysfunction is a major driver of heart disease and involves an inability of the endothelium to regulate blood pressure, blood clotting and various other factors .
Several studies suggest that curcumin leads to improvements in endothelial function. One study shows that is as effective as exercise, another shows that it works as well as the drug Atorvastatin .
But curcumin also reduces inflammation and oxidation (as discussed above), which are also important in heart disease.
In one study, 121 patients who were undergoing coronary artery bypass surgery were randomized to either placebo or 4 grams of curcumin per day, a few days before and after the surgery.
The curcumin group had a 65% decreased risk of experiencing a heart attack in the hospital .
6. Turmeric Can Help Prevent (And Perhaps Even Treat) Cancer
Cancer is a terrible disease, characterized by uncontrolled growth of cells. There are many different forms of cancer, but they do have several commonalities, some of which appear to be affected by curcumin supplementation .
Researchers have been studying curcumin as a beneficial herb in cancer treatment. It can affect cancer growth, development and spread at the molecular level .
Studies have shown that it can reduce angiogenesis (growth of new blood vessels in tumors), metastasis (spread of cancer), as well as contributing to the death of cancerous cells .
Multiple studies have shown that curcumin can reduce the growth of cancerous cells in the laboratory and inhibit the growth of tumours in test animals .
Whether high-dose curcumin (preferably with an absorption enhancer like pepper) can help treat cancer in humans has yet to be tested properly.
However, there is some evidence that it may help prevent cancer from occurring in the first place, especially cancers of the digestive system (like colorectal cancer) – where the concentration of curcumin is highest.
In one phase IIa clinical trial in 44 men with lesions in the colon that sometimes turn cancerous, 4 grams of curcumin per day for 30 days reduced the number of these lesions by 40% .
Maybe one day, curcumin will be used along with conventional cancer treatment. It’s too early to say for sure, but it looks promising and this is being intensively studied as we speak.
7. Curcumin May be Useful in Preventing and Treating Alzheimer’s Disease
Alzheimer’s disease is the most common neurodegenerative disease in the world and a leading cause of dementia.
Unfortunately, no good treatment is available for Alzheimer’s yet.
Therefore, preventing it from showing up in the first place is of utmost importance.
There may be good news on the horizon, because curcumin has been shown to cross the blood-brain barrier.
It is known that inflammation and oxidative damage play a role in Alzheimer’s disease. As we know, curcumin has beneficial effects on both.
But one key feature of Alzheimer’s disease is a buildup of protein tangles called Amyloid plaques. Studies show that curcumin can help clear these plaques .
8. Arthritis Patients Respond Very Well to Curcumin Supplementation
Arthritis is a common problem in Western countries.
There are several different types, but most involve some sort of inflammation in the joints.
Given that curcumin is a potent anti-inflammatory, it makes sense that it could help with arthritis. Several studies show this to be true.
In a pilot study of patients with rheumatoid arthritis, curcumin was even more effective than diclofenac, an anti-inflammatory drug .
Many other studies have looked at the effects of curcumin on arthritis and noted improvements in various symptoms .
9. Studies Show That Curcumin Has Incredible Benefits Against Depression
Curcumin has shown some promise in treating depression, an incredibly common disorder.
In a controlled trial, 60 patients were randomized into three groups .
One group took prozac, another group took a gram of curcumin and the third group took both prozac and curcumin.
After 6 weeks, curcumin had lead to improvements that were similar to prozac. The group that took both prozac and curcumin fared best.
According to this (small) study, curcumin is as effective as an antidepressant.
Depression is also linked to reduced levels of brain-derived neurotrophic factor and a shrinking hippocampus, a brain area with a role in learning and memory.
Curcumin boosts BNDF levels, potentially reversing some of these changes.
There is also some evidence that curcumin can boost levels of the brain neurotransmitters serotonin and dopamine .
10. Curcumin May Help Delay Ageing and Fight Age-Related Chronic Diseases
If curcumin can really help prevent heart disease, cancer and Alzheimer’s… then this would have obvious benefits for longevity.
For this reason, it has become very popular as an anti-aging supplement.
But given that oxidation and inflammation are believed to play a role in ageing, curcumin may have effects that go way beyond just prevention of disease .
