Micronutrients inhibit the development of lung tumors

Summary This study investigated the effect of dietary supplementation with a nutrient mixture containing lysine, proline, arginine, ascorbic acid, green tea extract, N-acetyl cysteine, selenium, copper and manganese on the development of lung tumors. Lung tumors were induced in mice which were fed either a regular diet or the same diet supplemented with a nutrient…

The continual consumption of fish oil-derived compounds reduces inflammation and oxidative stress

Summary This study investigated the effect of fish oil-derived compounds (PUFA) in patients with lung cancer. 33 patients with advanced inoperable lung cancer and undergoing chemotherapy were given either four capsules/day containing PUFA or no supplementation. It was found that fish oil-derived compounds reduced inflammation and oxidative stress. The decrease of the oxidative stress implicates…

Quercetin-derived compounds inhibit the growth and induce the death of cancer cells

Summary Quercetin is a natural antitumor substance whose derived compounds, quercetin glucuronides, can be found in the blood after ingestion of dietary supplements containing quercetin. This study investigated the effects of quercetin glucuronides in human lung cancer cells. The experiments demonstrated that quercetin glucuronides inhibit the growth and induce the death of cancer cells. More…

Micronutrients are effective against tumor invasion and metastasis

Summary Metalloproteinases (MMPs) are substances produced by malignant cells to digest the surrounding tissues, induce metastasis and spread through the body. This study examined the effect of various compounds on MMPs. The experiments, executed with human lung cancer cells, indicated that a nutrient mixture (NM) and the green tea-derived compound epigallocatechin gallate (EGCG) inhibited the…
