Components of an anticancer diet: dietary recommendations, restrictions and supplements of the Bill Henderson Protocol

The use of complementary and alternative medicines including dietary supplements, herbals and special diets to prevent or treat disease continues to be popular. The following paper provides a description of an alternative dietary approach to the self-management and treatment of cancer, the Bill Henderson Protocol (BHP). This diet encourages daily intake of raw foods, a combination of cottage cheese and flaxseed oil and a number of supplements. Some foods and food groups are restricted (e.g., gluten, meat, dairy). Early background theory that contributed to the protocol’s development is presented as is a summary of relevant evidence concerning the anti-cancer fighting properties of the individual components. Supplement intake is considered in relation to daily recommended intakes. Challenges and risks to protocol adherence are discussed. As with many complementary and alternative interventions, clear evidence of this dietary protocol’s safety and efficacy is lacking. Consumers of this protocol may require guidance on the ability of this protocol to meet their individual nutritional needs.

Cancer and metastasis: prevention and treatment by green tea

Metastasis is the most deadly aspect of cancer and results from several interconnected processes including cell proliferation, angiogenesis, cell adhesion, migration, and invasion into the surrounding tissue. The appearance of metastases in organs distant from the primary tumor is the most destructive feature of cancer. Metastasis remains the principal cause of the deaths of cancer patients despite decades of research aimed at restricting tumor growth. Therefore, inhibition of metastasis is one of the most important issues in cancer research. Several in vitro, in vivo, and epidemiological studies have reported that the consumption of green tea may decrease cancer risk. (-)-Epigallocatechin-3-gallate, major component of green tea, has been shown to inhibit tumor invasion and angiogenesis which are essential for tumor growth and metastasis. This article summarizes the effect of green tea and its major polyphenolic compounds on cancer and metastasis against most commonly diagnosed cancer sites.

Nutrient mixture including vitamin C, L-lysine, L-proline, and epigallocatechin is ineffective against tumor growth and metastasis in a syngeneic neuroblastoma model

BACKGROUND

The replacement of established evidence-based cancer therapy protocols (mainstream therapy) by unevaluated complementary and alternative medicine (CAM) is a challenge in pediatric oncology. We tested the hypothesis that oral application of L-lysine and ascorbic acid (Lysin C Drink) in combination with epigallocatechin-gallate (EGCG) and amino-acids (Epican forte) is effective in a preclinical model of neuroblastoma.

METHODS

Primary tumors and spontaneous metastases were induced in A/J mice by injection of NXS2 neuroblastoma cells. Mice were treated by daily oral gavage with L-lysine and ascorbic acid (Lysin C Drink) (equivalent to 150 mg ascorbic acid/day/mouse) (treatment A) or with EGCG plus ascorbic- and amino-acids (Epican forte) (9.2 mg/mouse) (treatment B). Treatment A was started in the prophylactic setting (7 days before tumor cell injection) as well as in the therapeutic setting (1 day after tumor cell inoculation). Finally, treatment B was evaluated alone and in combination with treatment A in the therapeutic setting. The effect on primary tumor growth and the development of spontaneous liver metastases was evaluated.

RESULTS

L-lysine and ascorbic acid (Lysin C Drink) and EGCG plus ascorbic- and amino-acids (Epican forte) are ineffective in reduction of primary tumor growth and prevention of spontaneous liver metastases in this model.

CONCLUSIONS

Neither a formal clinical development nor the use of these substances can be recommended for neuroblastoma.

Inhibition of pulmonary metastasis of melanoma b16fo cells in C57BL/6 mice by a nutrient mixture consisting of ascorbic Acid, lysine, proline, arginine, and green tea extract

The authors investigated the effect of a nutrient mixture (NM) on lung metastasis by B16F0 melanoma cells in C57BL/6 female mice. Mice were divided into equal groups (1 to 6) and injected via tail vein with B16F0 cells (groups 1 to 4), B16FO cells pretreated with NM (group 5), or saline (group 6). Groups 1, 3, 4, 5, and 6 were fed the control diet and group 2 the 0.5% NM supplemented diet. Groups 3 and 4 received NM intraperitoneally (IP) and intravenously (IV), respectively. Two weeks later, pulmonary metastatic colonies were counted. Pulmonary colonization was reduced by 63% in mice supplemented with NM diet, by 86% in mice receiving NM by IP and IV injections, and completely inhibited in mice injected with melanoma cells pretreated with NM. These results show that NM is effective in inhibiting the metastasis of B16FO melanoma cells.
