Tomatoes contain lycopene, a red coloured carotene, which is known to be extremely protective against breast, colon, lung, skin and prostate cancers. Lycopene is known to naturalise harmful oxygen free radicals before they can damage cells. A recent study from 2016 concluded that lycopene also inhibits cell proliferation and triggers apoptotic cell death in prostate cancer.*

Beetroots are known to have stimulating effects on liver detoxification. Beets get their rich purple colour from betacyanin, which has been shown to be a strong cancer-fighting agent. A study conducted in 2015 also showed that beetroot extract has cancer preventative effects against different types of cancers.*

This aromatic herb that is often used as a pizza spice contains thymol and carvacrol, two incredibly powerful antimicrobials, which have been shown to inhibit the growth of bacteria. A recent study also showed that carvacrol inhibited proliferation and mitigation of colon cancer cells, concluding that carvacrol may have therapeutic effects on prevention and treatment of colon cancer.*

A recent study demonstrated for the first-time, distinct tumour-suppressive effect of oregano in breast cancer (Kubatka P; Kello M; Kajo K et al. Eur J Nutr (2017) 56: 1303. doi:10.1007/s00394-016-1181-5.
A backbone of traditional Chinese and Indian medicine, Turmeric is known to be one of the best natural anti-inflammatories. The yellow pigment of turmeric is called curcumin, which is known to protect cells from free radicals, which may damage the cellular DNA, leading to various types of cancer. A meta-analysis published in 2016, looked at eight RCTs and concluded that curcumin lowered circulating key inflammatory modulator, such as TNF-a.*
