Food Therapy: Dried Peas, The Best in Prediction, Prevention and Treatment of Liver Diseases

Kyle J. Norton


Intake of dried peas daily and regularly may associate to reduce risk of liver diseases, scientists at some respectable institute studies suggested.

Dried pea is a small but nutritionally mighty member of the legume family, genus Pisum belongings to the family Fabaceae with healthy source of proteins, fibers, vitamins and minerals.

Liver diseases are set of medical condition, ranging from Cirrhosis, or scarring of the liver. Inflammation (hepatitis) from infectious (hepatitis B, hepatitis C) to benign and malignant tumors.

In a hydroalcoholic extract (PE) of pea (Pisum sativum L.) by-product was investigate for its hepatoprotective against CCl4-induced oxidative stress and hepatic damage in rats, researchers at the Cairo University after taking account of existed con founders, found that
1. The by product displayed a significant effect in reduced ROS expression in induction of liver damamge through enhance antioxidant activity.
2. N-butanol fraction isolated from hydroalcoholic extract (PE) demonstrated stronger liver protective effect in compare to other petrochemicals.

The findings demonstrated that  hydroalcoholic extract (PE) of pea by-product can be utilized to obtain high value added products for therapeutic use in ameliorated risk and treatment liver diseases.

People who have a history of liver problems may consider to add portions of dried peas into their diet for preventive measure.

Further analysis the study also indicated that the by product also exert a significant antioxidant activity against the free radical expression and intimated a chain of harmful domino effect in inducing oxidative stress in the liver, which has been considered as a conjoint pathological mechanism.

Dr. Li S, the lead author at the University of Hong Kong, said, "(there is no surprise that) various factors that cause oxidative stress in liver and effects of antioxidants in the prevention and treatment of liver diseases ......".

In deed, application of antioxidants in animal studies has revealed a significant effect in prevented and cured liver diseases involving oxidative stress.

In the concerns of types of phytochemicals may have contributed to the hepatoprotective effect from peas, researchers at the Kyoto Pharmaceutical University launched an investigation to isolate some suspected chemical compounds from the young seedpods of garden peas, showed that

1. Not all chemicals isolated exerted similar in liver protection

2. Some compounds are more effective in compared to others

Further differentiation, researchers suggested, out of many components, Quercetin 3-sophorotrioside, was found to show clinical significantly protective effects on liver injury induced by D-galactosamine and lipopolysaccharide and by carbon tetrachloride in mice study, in compared those of ionone glucoside, pisumionoside, a phenethyl glycoside, sayaendoside, and two acylated flavonol oligoglycosides, pisumflavonosides.

More importantly, in support of the above analysis, researchers at the Changhai Hospital also conducted a study to evaluate the alpha-fetoprotein reactive to Pisum sativum agglutinin levels (AFP-R-PSA) of 24 patients with hepatocellular carcinoma (HCC) and 54 patients with benign liver diseases (BLD) showed that

1. Alpha-fetoprotein levels were higher in patient with liver cancer and suggested that the measured AFP-R-PSA level above 25% may be considered as a value in highly suggestive of HCC with a positive prediction value of 98% accuracy.
2. According to the sensitivity of the test, value of 74% in serum AFP level below 400 micrograms/L was found in 31 patients with a tumor size less than 5cm.
3. In the combined test of (AFP-R-PSA), the detection rate of small HCC was increased from 32% to 87%.

It is amazing that Pisum sativum lectin or agglutinin (PSA), another chemical compound isolated from peas also have a strong effect in prediction of the development and size benign liver diseases (BLD) and liver cancers.

With all information collected from the data of medical literature, we believed,  the efficacy of dried peas in reduced risk and treatment of liver diseases may be attributed to various unknown mechanisms, that are waiting to discover.

These effectiveness also does not assure that patients with liver disease can be cured by adding a significant portions of pea into their diet, because of the small sample sizes and only ingredients isolated from peas were used to perform these testing in all studies. 

But taking together, it is safe to conclude that intake of dried peas may have a profound and positive potency in induced hetapoprotective against liver diseases.
