– HOW VITAMINS WORK IN MAINTAINING HEALTH –
Vitamins are essential for the proper functioning of the body. They are able to prevent and help cure diseases, help absorb other nutrients ingested in food, regulate our body functions, reduce stress and even improve mood.
The main natural sources of vitamins are fruits, greens and vegetables, but they can also be found in food in general. The ideal is to ingest them daily, regardless of the source.
Vitamins are also found in multivitamins, which provide specific amounts and meet individual physiological needs.
According to data from the Ministry of Health, the diseases that most kill Brazilians are: cancer, heart attack, obesity, stroke and illnesses linked to the respiratory system. The curious thing is that it is precisely these diseases that benefit most from prevention.
There are several ways to detect a disease, find out if you have a tendency to develop it and even prevent it. Scientists are proving in studies that the daily intake of different vitamins above nutritional doses can be great allies in disease prevention and health maintenance. If the intention is to prevent a pathology, a nutrient can be used continuously.
It was discovered that a nutrient in low doses is an important piece in the complex machinery of metabolism, but that in high doses it starts to have a specific biochemical action, which can lead to the prevention of diseases. Nutraceuticals act like a medicine by providing the body with the missing nutrients. This nutraceutical action of nutrients originated preventive medicine, in its different areas, orthomolecular, nutrition and nutrology.
See some studies related to the prevention and cure that these precious ingredients can benefit our health:
HOW VITAMINS WORK IN MAINTAINING HEALTH
SUPPLEMENTATION AND ALZHEIMER DISEASE
The brain is a metabolically active organ that produces high levels of free radicals. These free radicals can bombard the cell membranes of neurons causing premature loss of function. Alzheimer’s disease has become a major public health problem in the world and is the most common cause of illness in the elderly. Alzheimer’s is a degenerative disease, that is, the brain cells we call neurons die slowly, insidiously and progressively. The disease affects not only memory, but other cognitive functions. As you age, your chances of getting Alzheimer’s increase. There are still no studies that prove that this pathology is influenced by genetics.
doctor Denham Harman proposed that brain aging is associated with a progressive imbalance between antioxidant defense and pro-oxidant species, which may occur as a result of an increase in free radical production and a reduction in antioxidant defense. Research shows that oxidative stress generates changes in the brain of people with Alzheimer’s disease.
In this context, some observational studies have suggested that supplementation of antioxidants, including vitamins C and E, or a diet rich in these nutrients can prevent the oxidative stress that possibly causes the neuronal loss observed in Alzheimer’s Disease, thus decreasing the risk for pathology.
A randomized, controlled double-blind clinical study evaluated the effectiveness of supplementation with a compound based on EPA/DHA, uridine, choline and micronutrients in patients with mild Alzheimer’s disease. After 12 weeks of evaluation, the study concluded that the patients had improved memory. Research shows that the deficiency of some nutrients is possibly related to the worsening of memory, which may be the manifestation of a more serious disease. On the other hand, the intake of these nutrients, in the necessary amounts, is difficult to achieve with a regular diet, requiring supplementation.
SUPPLEMENTATION AND PARKINSON DISEASE
Parkinson’s disease is a neurodegenerative disease characterized by the presence of rigidity, tremor and slowness of movement, being one of the most common movement disorders in the elderly population. Studies have shown that oxidative stress, prolonged use of the drug levodopa in the treatment of this disease and increased plasma concentration of homocysteine are agents that aggravate symptoms. Many nutrients are researched both in the prevention and treatment of the disease, among which antioxidant vitamins stand out. There has recently been an increase in the number of studies on the action of these vitamins, mitigating the damage caused to the brain in these patients. Studies and scientific literature demonstrate recent information on the positive influence of vitamins C, E, B6, B12 and folic acid on Parkinson’s Disease.

SUPPLEMENTATION AND CARDIOVASCULAR PROBLEMS
According to Japanese research presented in the Journal of the American Heart Association, eating more foods that contain B vitamins (folic acid, B-6) reduces the risk of stroke and heart disease for women and may reduce the risk of heart failure in men.
“People need to eat a diet with more folic acid and vitamin B-6, which can lead to heart disease prevention,” said Hiroyasu Iso, MD, professor of public health at Osaka University.
Conclusions on the value of B vitamins are consistent with studies in Europe and North America. The researchers divided the participants into five groups based on their intake of folic acid, vitamins B-6 and vitamin B-12. Comparing them against their diets with more or less of each of the nutrients, it was found that a higher consumption of folic acid and vitamin B-6 is associated with significantly fewer deaths from heart failure in men and a significantly lower deaths from stroke, heart disease and cardiovascular disease in women. Vitamin B-12 intake was not associated with reduced risk of mortality.
Folic acid and vitamin B6 may help protect against cardiovascular disease by lowering homocysteine levels, researchers said. Homocysteine is a blood amino acid that is affected by diet and hereditary factors. Folic acid and other B vitamins help break down homocysteine in the body.
There is no direct causal link, but evidence has shown that homocysteine can damage the inner lining of arteries and promote the formation of blood clots.
These are some examples of how vitamins can be of great help in preventing certain diseases. In addition to filling nutritional deficiencies with a multivitamin (making sure that no nutrients are missing for the proper functioning of the body), you can use some specific nutrients in doses above the nutritional doses (becoming a nutraceutical) to help prevent diseases. and better quality of life.
