In recent decades, the prevalence of obesity and overweight has increased worldwide, in both men and women. According to the latest evaluation carried out by the Cancer Research Association of the University of Verona in 2017, overweight and obesity are proven risk factors for 13 tumor sites, with risk estimates that vary widely depending on the tumor site . Obesity is also related to a worse prognosis for some cancers, particularly breast and colon cancers. Childhood and adolescent obesity, also on the rise in many countries, has been associated with an increased risk of cancer in adulthood. One of the main causes of obesity is the imbalance in energy balance favored by a diet rich in processed foods, red meat, trans and saturated fatty acids, sugary foods and drinks and low in fruit and vegetables, legumes and whole grains. The main national and international recommendations to reduce the prevalence of obesity include a balanced diet and regular physical activity.
The change in eating habits and lifestyle (we are therefore talking about a sedentary lifestyle and an increase in simple sugars and unsaturated fats in the diet) is now a global phenomenon. Even in rural populations in Southern Africa* there has been an increase in the risk of cancer.
Therefore, nutrition is no longer just a risk factor for cerebral and cardiovascular diseases, being among the leading causes of hospitalization in industrialized countries. It becomes one of the most important and most avoidable risks of cancer which is the health emergency of these decades.
Learning to eat, learning to live to live better and also to prevent Cancer.
Vacations are over. Heat is over. Work is coming full circle again. First colds are back, and Italian health care is preparing to support the new flu wave, and with it the new Sars-19 spike that is likely to be in winter, like all flu spikes.
Recent studies by Italian groups have shown a relationship between low vitamin D levels and COVID onset, especially in populations in northern Italy. Could this be a possible contributing cause (along with particulate pollution that acted as a vehicle for the virus) of why Northern Italy was so plagued by COVID in the first and second waves? In fact, the last 30 years in Italy have seen a real global decline in vitamin D levels. The cause of this phenomenon is, as always, multifactorial.
1)The change in the tilt of the Earth’s axis is related to the change in the rotation of the two poles (instead of north to south currently to the east) which is in turn influenced by the ongoing climate change (the Earth’s axis is responsible for the seasons) and which is responsible for the reduced ability of the sun in our latitudes to fix Vitamin D.
2)The insufficient use of the foods available in the Italian territory of vitamin supplementation.
3) Fish from our seas, being very lean, have lower levels of vitamin D than those found in fish from the northern seas.
4) Vitamin D plays an important role in modulating the immune system, and so its deficiency may be associated with an improperly adapted immune system.
Vitamin D deficiency is also often found in young adolescents, students, complicit in the closing of recent years.
Therefore, a proper assessment of vitamin D level is definitely indicated not only in post-menopausal women, but in general also in a population poorly exposed to the sun and sedentary, in order to improve our body’s ability to respond to infections that we will have to live with for a long time.
