of skin cancer are the most common cancer globally, and by far the most ubiquitous of these tumors are caused by excessive exposure to sunlight.
of solar ultraviolet radiation (UVR) are ones who are responsible for causing several pre-malignant processes in the skin. Not only do they damage DNA directly, but they also cause inflammation, excess free radical production and immunosuppression. These factors combine to form a tumourigenic cocktail that increases the risk for melanoma and non-melanoma skin cancer.

...There is also evidence that the lack of exposure to the sun's rays is a significant factor in the development of diseases such as multiple sclerosis and certain malignant diseases other than skin cancer.
It is important to note that the human body does not attempt to prevent the accumulation of radiation damage and repair mechanisms, so running at relatively low levels of radiation exposure.
These processes include both intrinsic and extrinsic (plant derived) antioxidants, enzymes and other protective plant-based compounds and work in the following ways:
1 Activation mechanisms against free radicals and oxidative stress.
2 Acceleration of programmed cell death (apoptosis) pre-cancerous cells.
3 Activation of DNA repair mechanisms at low levels of radiation exposure.
There is a dichotomy in relation to UVR. On the one hand, in order to maintain normal physiological processes, we need a certain amount of sun exposure. However, if we are exposed to excessive amounts of UVR and inadequate protection of biological processes, increase our risk for several different types of skin cancer.
It seems obvious that such people lived eons with constant exposure to sunlight, our bodies adapt to protective strategies in the fight against the harmful effects of UVR while still obtaining the benefits thereof. Now we know that some of these strategies, but to understand how to improve them, we have to look back thousands of years on the vital role of nutrient-dense plant foods play in this regard.
Only a few thousand years of our hunter-gatherer ancestors wandered more or less naked, mostly in sun-drenched areas on the planet. With more extensive ozone layer, they were probably exposed to somewhat lower doses of UV radiation per unit time than we have today. However, they undoubtedly spent some time in the sun, while they hunted and collected plant foods. They also had dark skin, which gave them an extra measure (but not complete) protection against excessive exposure to UVR. There is evidence that they lived well into their sixties and are therefore subject to significant UVR exposures for several decades.
protective phytonutrients
key to our ancestors' success in the fight against UVR damage to their consumption of a diet rich in phytonutrients. Due to their active lifestyles, hunter-gatherer communities consuming high calorie dijeta.Razlika between their high-calorie diet and modern high-calorie diet is that the former consisted mainly rich spicy (hot), phytonutrient-dense plant foods, while the modern diet is dominated by relatively mild nutrient lack of plant food.
nutritional characteristics of plants that hunter-gatherers consumed were different than here in the far larger phytonutrient / calorie the ratio of the plants we eat today. They are available today are mostly energy-dense plant foods with a lot lower phytonutrient / calorie ratio.
There are two reasons for this. First, we eat a lot of grain based foods that have very high levels of carbohydrates and relatively low levels of phytonutrient. Second, over the centuries, we have most of our cultivated varieties of grains, fruits and vegetables that are far larger, sweeter and starchier than they were in their natural state.
Add to this the modern chemical farming methods, and we now have a plant food with a very low phytonutrient / calorie ratio, which consist mainly of water and carbohydrates. They provide much less protection than the substance which is several thousand years ago. This translates into a reduced intake of phytonutrients, which, in appropriate amounts, it can protect us from UVR and other cancer-causing environmental factors.
only food categories that have more or less escaped plant breeders' attention to the spices. Spices are plant foods that are closest to our ancestors ate. They are extremely high phytonutrient / calorie ratio and contain high concentrations of various powerful antioxidants and other protective nutrients.
Recent scientific evidence suggests that several herbs contain compounds that are highly effective in the fight against UVR damage to the skin. These molecules have the ability to act as direct and indirect antioxidants. They are anti-inflammatory and immunomodulatory properties and can activate genes that control the process of permanent protection against UVR damage. Scientists working in this field have also noticed that several antioxidant compounds (found in plants phytonutrient rich) have a better protective effect than a high dose antioxidant supplements.
spices known to have some protective effects against radiation damage are:
Turmeric has anti-inflammatory, antioxidant, Curcumin , which is remarkable abilities in the fight against cancer against several cancers, including melanoma.
Mustard contains sulphorafane , non-antioxidant compounds also found in cruciferous plants such as broccoli. Sulphorafane works by activating the body's internal cellular defense against UVR and was screened counter skin cancer when used both internally and locally.
Curcumin and sulphoraphane only two spices, based on compounds that are currently being studied as possible treatments for a variety of skin and other cancers. However, as the spices provide a wide range of antioxidants and other protective substances, it is likely that there are many more than those who can help include skin cancer, such as no doubt did for our hunter-gatherer ancestors.
