Turmeric grows mainly in South Asia 、 India 、 Indonesia , Its roots and underground stems can be ground into powder and used as seasoning and natural pigment . The kind of turmeric Curcumin The content accounts for about 2-6%

Curcumin like components	The proportion
Curcumin	80%
demethoxycurcumin	18%
bisdemethoxycurcumin	2%

At present, there are many researchers , Try to improve the bioavailability of curcumin ：

（ The following passage doesn't look very human , If you don't understand, you can skip , Look at the small conclusions behind these three points .）

1. Nano turmeric

The researchers prepared turmeric in the form of nano colloid , The original particle size is about 22.75um The turmeric powder is reduced to 0.19um, It can improve the solubility 、 And light resistant 、 It's also stable to heat . The researchers put 30mg The nano turmeric is coated in a film made of starch , And match it with 100mL The subjects were given boiling water to ingest , Then blood was drawn to test the content of turmeric in plasma , It is found that the utilization rate of nano turmeric is higher than that of turmeric powder 27 times , About... After ingestion 30 The highest detectable concentration in plasma in minutes , Then it began to fall , It will improve slightly in six hours , Then it plummeted （Ref 6）.

2. Turmeric liposome

Turmeric is a fat soluble component , Therefore, the researchers made turmeric into solid lipid turmeric particles , Subjects were asked to ingest separately 650mg Curcuma liposome capsules and 95% Turmeric extract from , Subjects who ingested turmeric liposomes were 2 The peak concentration of curcumin can be detected in plasma after hours , For 22.43 ng/mL, Turmeric could not be detected in the plasma of the group of turmeric extract （Ref 7）.

3. Phospholipid complex

Curcumin can hydrogen bond because of its polar group 、 I tried to form a complex with lecithin . Some manufacturers use turmeric extract to 1:2 In proportion to lecithin , In animal experiments, it was found that the absorption rate of this complex was higher than that of general turmeric 20 More than times . In the human experiment, the subjects in the experimental group were divided into 「 Take a low dose 」 And 「 High dose turmeric – Phospholipid complex 」 My experimental group , Take about 209mg as well as 376mg This complex ; And ingestion 1800mg Control group of general curcumin extract . It turns out that , No turmeric was detected in the plasma of the control group , The experimental group detected , In the high-dose group, after ingestion 2 Hours , The concentration in human blood can reach the peak , About 50.3ng/dL, Then it slowly drops . On the whole , The human absorption rate of this product is higher than that of ordinary turmeric 29 times . It is worth noting that , The highest content of curcumin extract detected in human plasma is not curcumin , But another ingredient in turmeric demethoxycurcumin（Ref 8）.

So the point of this paragraph is ： Daily food is usually only curry with turmeric , Curry dishes are usually cooked with oil , It is a form that is relatively easy to absorb . Natural turmeric contains curcumin , But turmeric is not easily soluble in water, so it is not easy to absorb , And it's easy to metabolize , It is difficult to produce high concentrations in the body . To solve this problem , Scientists used 「 Nanotechnology 」、「 Liposomes 」、「 Phospholipid complex 」 Methods such as , To increase the absorption of turmeric . If you buy a whole piece of turmeric to eat , Or buy a packet of turmeric powder to soak in water , Basically, you can't absorb any curcumin .

Although curcumin has been shown to inhibit many inflammatory cellular pathways and the production of proinflammatory cytokines in cell models , But when applied to human experiments in patients with Alzheimer's disease , It doesn't seem to have a significant effect . This may be related to bioavailability and blood-brain barrier .

● In a study of colorectal cancer ,15 Of the subjects 2 Diarrhea occurred in subjects , The doses given were 0.45mg as well as 3.6mg, One of them continued the experiment after giving antidiarrheal , The other left the experiment . Blood tests found that 4 Subjects developed alkaline phosphatase （alkaline phosphatase） A rising situation ;3 One subject was lactate dehydrogenase （lactate dehydrogenase） More than before the intervention 150%（Ref 10）.

In addition to the above two studies , Most of the subjects in the study seemed to have good tolerance to curcumin , Indeed, several studies have shown that a few subjects have gastrointestinal symptoms, including abdominal pain 、 Vomiting, etc , Therefore, the safe dose of curcumin may need more studies to confirm

At the end of last year, the Consumer Foundation gave 19 Plant commercially available turmeric powder for spot check , Two of them were found to have excessive lead content . Therefore, for the magical effect of turmeric, they flocked to buy turmeric powder , Start eating turmeric , Is it possible to eat the benefits of turmeric before , Heavy metal poisoning first ？ In terms of products , Of course, there are many curcumin products on the market , The price is per can 1000 Dollar off , The number of capsules per can of each product varies , The curcumin dose of each capsule is not necessarily . Among the above studies, some turmeric comes from specific patented products , Although the results of the research are very good , but As long as there are manufacturers involved , Usually the result is to maintain a relatively high degree of doubt .

また、 Fatty liver disease などの people にウコンを 勧 めないもう One つの reason が、ウコンに contain まれる「 A kind of 」にあると Shallow さんは Words す.

　「ウコンのサプリには More quantity の A kind of を contain むものがあります.しかし、 A kind of の Content が Record されていないものがあるのです. A kind of は a の Liver の Well い Fang に Influence を And ぼすことがわかっています.その representative が、C Hepatitis B や Fatty liver disease です. Prevent anemia に Fruit があることで know られる A kind of ですが、 Too many "" で Liver に Accumulate すると、フリーラジカル（ Active acid ）を He was born させ、 Hepatocytes を Wound つけ、 inflammation を Turn させます. Line dimension （＊3）が Enter んで Liver が hard くなるなどして、 The liver is hard や liver がんになる possibility も high まります. private のこれまでの Therapeutic surgery では、 Fatty liver disease の people の blood を Tune べると、ほとんどの people が A kind of が Too long でした.このため、 Fatty liver disease の people はウコンは Limit した Fang がいい. Same as じく A kind of を contain むシジミなども Tongqi です」（ Shallow さん）

（ Mr. asabu also said , Another reason not to recommend turmeric to fatty liver and others is that turmeric contains “ iron ”.

“ There is more iron in the nutritional supplement food of turmeric . however , There is also no record of iron content . Iron can have adverse effects on some people with poor liver . Its representative is C Hepatitis B and fatty liver . Because it has the effect of preventing anemia, excessive iron intake , If it accumulates in the liver , It produces free radicals （ Reactive oxygen species ）, Damage liver cells , Make inflammation worse . Fibrosis （＊3） With the deterioration of the liver , The possibility of liver cirrhosis and liver cancer will also increase . In my treatment experience so far , The blood of people with fatty liver was investigated , Most people have excess iron . therefore , It's better to control turmeric for people with fatty liver . There are also clams and shells containing iron ”（ Shallow ））

また、うこん Tea, etc による Cases of liver obstruction も Report されているが、 autumn ウコンの Rhizome は、クルクミン Protoplasm の He にもミネラル branch （ The minute ）が Chen Fu に contain まれているものがある. example えばC Patients with chronic hepatitis は、 Have a plan を rise こしやすいことから Make food restriction therapy が Sheshi されるが、そのような Occasion には、うこん contain の The minute が Liver に Too long な Influence を And ばすことがあり、 Be careful が necessary といわれている[37]（なお Refined されたクルクミン Protoplasm の Occasion には、 contain ミネラルの The problem is は rise こらない）.

（ in addition , Although examples of liver dysfunction caused by ginger yellow tea, etc. have also been reported , But the rhizome of autumn Curcuma except curcumin , It's also rich in minerals （ Iron ）. for example ,C Patients with chronic hepatitis B are prone to iron excess , So iron restricted diet therapy was implemented , But in this case , The iron component containing turmeric has an excess effect on the liver , We need to pay attention to （ If it's refined curcumin , There will be no problem with minerals ））
