Maternal prenatal use of vitamins and folic acid reduces the risk of leukemia in offspring

Summary This study analyzed the effect of maternal prenatal vitamin supplementation with folic acid and other vitamins on childhood leukemia. Data on prenatal use of folic acid and vitamins were obtained from 12 studies, including more than 7,000 children with leukemia and 11,635 without leukemia. The results suggested that maternal prenatal use of vitamins and…

Lysine counteracts leukemia progression

Summary This study evaluated the effect of the amino acid lysine against leukemia. Various analyses were performed, including those of cells. It was found that lysine was able to induce the death of malignant cells and decrease metalloproteinases (MMPs). MMPs are substances produced by malignant cells to digest the surrounding tissues and spread through the…

Fish oil supplementation elicits positive effect among children with leukemia

Summary This study determined the effect of fish oil supplementation among children with leukemia. 51 children were allocated into 2 groups and given either fish oil supplementation or no treatment. Compared with children who did not receive any supplementation, children who consumed fish oil had significant positive effects on appetite, caloric intake, and upper arm…

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…

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…

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…

Isoflavonoids are effective against brain tumor

Summary Isoflavonoids are naturally occurring compounds and this study investigated their impact on brain tumor. The experiments were performed with cells and rats. The results revealed that dietary isoflavonoids were effective against brain tumor. Further details can be found in the study.

Lower vitamin D blood levels are associated with an increased risk of bladder cancer

Summary This study evaluated the relationship between vitamin D and bladder cancer. Blood samples were taken from 250 patients with bladder cancer. The results showed that lower blood levels of vitamin D were associated with an increased risk of bladder cancer. More details can be found in the study.

Higher micronutrient intake is associated with reduced risk of bladder cancer

Summary This study investigated the association between micronutrients intake and bladder cancer. A questionnaire was administered to 322 patients with bladder cancer and 239 persons without bladder cancer. The researchers concluded that higher intakes of carotenoids, vitamin D, thiamin, niacin, and vitamin E were associated with a reduced risk of bladder cancer. Further details can…

Cruciferous vegetables consumption reduces the risk of kidney cancer
