#Tomato's #Lycopene, a Non-Provitamin A #Carotenoid, Inhibits the Risk of Non-alcoholic Steatohepatitis NASH, Researchers Say

Kyle J. Norton

Nonalcoholic steatohepatitis (NASH), is a type of inflammatory non-alcoholic fatty liver disease caused by a buildup of fat in the liver.

Most cases of NASH if untreated can lead to liver scars or building up of scars over time, a condition of liver cirrhosis, and one of the most common causes of liver cancer.

Most people with non-inflammatory-alcoholic fatty liver disease are asymptomatic, however, the inflammation caused by non-alcoholic steatohepatitis may induce liver damage, leading to a reduced function of the liver that orchestrates the onset of liver symptoms.

The most common symptoms are abdominal swelling, enlarged blood vessels just beneath the skin's surface, enlarged spleen, red palms, and jaundice.

If you have experienced some of the aforementioned symptoms that do not recede in a short period of time, you may have some forms of liver disease. Please check with your doctor to rule out the possibility.

Out of many prevalent factors associated with increased risk of non-alcoholic steatohepatitis, some researchers suggested the rise of the condition in the US population may be correlated to the promotion of the Western diet over the past few decades.

Dr. H. Cortez-Pinto, the lead scientist said, " Comparison of their diet history with control data (C) revealed that carbohydrate consumption was lower in patients (P): P—243.6±5.7g vs. C—261.5±1.6g, P<0.05, and most patients had very low fiber intake. Conversely, total fat consumption was higher in patients: P—79.7±1.7g vs. 73.0±0.4, P<0.01. A significantly higher intake of n-6 fatty acids (P=0.003) and the then-6/n-3 ratio was found in patients, P<0.001".

And, "Our results suggest that the quality and combination of carbohydrates and fat intake may be more relevant than their isolated amount; an increased fat intake with an excessive amount of n-6 fatty acids can be implicated in promoting necro-inflammation, and provides further grounds for individualized dietary therapy".

Tomato is a red, edible fruit, genus Solanum, belonging to the family Solanaceae, native to South America. Because of its health benefits, the tomato is grown worldwide for the commercial purpose
and often in the greenhouse.

In the urgency to discover healthy foods for the treatment of liver disease, researchers examined the effect of lycopene, a non-provitamin A carotenoid, and the pigment principally responsible for the characteristic deep-red color of ripe tomato and tomato products on subjects with non-alcoholic steatohepatitis.


According to the review of the epidemiological study, tomato extract supplementation showed a significant protective effect against HFD-induced hepatic inflammation compared to supplementation of lycopene.

In patients with NASH, increased levels of plasma lycopene may have a strong impact on the progression of NASH as patients have been shown to have significantly reduced plasma lycopene.


In vivo, dietary lycopene inhibits liver carcinogen-induced preneoplastic lesions in the rat liver which was effective in reducing NASH-promotion in rats.


The efficacy of lycopene in the inhibition of NASH and another chronic disease may be associated with the body's lycopene metabolism involved in both the chemical and enzymatic modifications.


Furthermore, in vivo synthesis of ACR from lycopene was shown to attenuate hepatic steatosis, by decreasing the macrophage-conditioned medium-induced and TNFα-mediated induction of pro-inflammatory cytokine and chemokines.

Taken together, tomatoes processed with a high amount of lycopene may be considered dietary supplements for the prevention and treatment of NASH, pending to large sample size and multicenter human study.

Intake of lycopene in the form of a supplement should be taken with extreme care to prevent overdose acute liver toxicity.
