Let’s talk about a natural way to get rid of polyps which are little growths that can occur in many places in the body. Polyps can occur on the vocal cords, nasal passages, colon, and bladder and many other places. We are going to discuss a natural way to get rid of polyps but first we need to understand why ...

The processed Aloe vera gel (PAG) contains immunomodulatory polysaccharides, which consists of a mixture of polymer chains of b-(1,4)-linked acetylated galactomannan with different lengths. PAG was shown to inhibit azoxymethane(AOM)-initiated and dextran sodium sulfate(DSS)-promoted colon carcinogenesis model in mice. In the present study, we examined the molecular mechanisms for the inhibition of colitis-associated colon carcinogenesis by PAG. PAG administration significantly inhibited the production of pro-inflammatory cytokines and mediators in the colon. Western blot analysis using the colon extracts showed that PAG administration reduced the activation of NF-kB resulting in the inhibition of iNOS and COX-2 expression. PAG appeared to inhibit NF-kB activation through the PPARγ activation. PAG administration also inhibited the expression and phosphorylation of STAT3, which was known to connect inflammation and cancer. PAG administration also inhibited cell cycle progression-related transcription factors such as the proliferating cell nuclear antigen (PCNA), ERK, cyclin-dependent kinase (CDK) 4 and cyclin D1. In contrast, PAG administration increased the expression of CDX2, which was known to be a tumor suppressor in colorectal cancers. These findings show that PAG suppresses colitis-related colon carcinogenesis by inhibiting both chronic inflammation and cell cycle progression in the colon.

When regular starches are cooked and then cooled, some of the starch recrystallizes into resistant starch. For this reason, pasta salad can be healthier than hot pasta and potato salad healthier than a baked potato.

A leading cause of cancer deaths worldwide, colon cancer is famously resistant to treatment. Now the biological pathway behind the growth of colon cancer has been discovered by researchers who have been able block it with vitamin A.

Eating walnuts may change gut bacteria in a way that suppresses colon cancer, researchers report. A team of researchers found that mice that ate 7-10.5 percent of their total calories as walnuts developed fewer colon cancers. The effect was most pronounced in male mice, which had 2.3 times fewer tumors when fed walnuts as part of a diet similar to the typical American's.
