Why wholefood supplements?
Two types of supplements are available: one is made from chemicals extracted from food or is made synthetically which are called vitamin and minerals. The other is supplements made from concentrating whole foods. If these foods have good benefits, then a supplement made from them is a good way to improve a poor diet or for someone not eating enough of these foods. They can also enhance a good diet with the benefits they provide to make the diet better.
The majority of studies, to date, have studied extracted chemicals which is the first group: vitamins and minerals. Some have shown a benefit.
More recently academic attention has turned towards the study of concentrated whole food supplements, particularly foods rich in polyphenols and other phytochemicals such as herbs, spices, green vegetables, teas and colourful fruits which have appeared to be beneficial in environmental studies.
Pomi-T capsules is an example. So far, the largest trial analysing phytochemical-rich food extracts is the National Cancer Research Network Pomi-T study. This study combined four different food types (pomegranate, green tea, broccoli and turmeric) in order to provide a wide spectrum of synergistically acting nutrients, whilst at the same time avoiding over-consumption of one particular phytochemical which may happen. eg if you take a full strength turmeric capsule the body response will be different than the level of tumeric provided in Pomi-T. It involved two hundred men, with localised prostate cancer which was managed with active surveillance or watchful waiting experiencing a PSA relapse.
The results, announced as an oral presentation at the American Society of Clinical Oncology conference Chicago, showed a statistically significant, 63% reduction in the median PSA progression rate compared to placebo. This is an excellent result.
In the UK, the Institute of Preventative Medicine have plans to include Pomi-T supplement into the next national prostate cancer prevention study. This study will be recruiting men with a higher genetic risk of prostate cancer identified in the national RAPPER study co-ordinated from the Institute of Cancer Research. Further trials are being designed involving individuals with skin, colorectal and bladder cancer. In the meantime, a trial is passing through the regulatory process to investigate whether the natural anti-inflammatory properties of these ingredients could help joint pains after breast cancer.
