Buying vitamins is a waste of money

Eat vegetables, exercises, and of course, take vitamins to be healthy - sounds like a simple advice and fairly clear.

But not everything is rosy - some dietary supplements with tablets can seriously harm the body. No decades of research have found any concrete evidence that taking tablets with vitamins and a variety of applications has a particularly beneficial effect on human health.

 In fact, recent studies have shown the opposite direction: it turned out that some vitamins can hurt you. Some were associated with an increased risk of cancer, while others were associated with kidney stones.

 But despite the clear growth of knowledge in this area, the habit of "using tablets" in humans over the past decade is still the same.

 So, here are the vitamins and supplements to be addressed, and those that should be avoided:

Multivitamins do not use -

 You get everything you need with a balanced diet. For decades, multivitamins were thought to be necessary for public health. Vitamin C "to strengthen the immune system," vitamin A to protect your eyes, vitamin B to be "toned." You can get these ingredients from the food you eat, and studies suggest that excessive consumption of these ingredients may be harmful.

 For example, a 2011 study of 39,000 women over the age of 25 showed that women who took them over the long term had a higher overall risk of death than those who did not.

 Vitamin D Drink it -

 Helps your bones stay strong and harder to get from food. Vitamin D is absent in most foods we eat, but it is an important ingredient that helps bones absorb calcium. Sunlight stimulates its production directly through the human body, but in the winter it is difficult to get enough. Several recent studies have found that people who took vitamin D regularly live on average more than those who did not.

 Antioxidants -

 Excess of these components is associated with an increased risk of certain cancers. It is better to eat grapes only. Vitamins A, C and E are antioxidants found in many foods - especially berries and vegetables - and are advertised for their alleged ability to protect against cancer. But studies show that with an excess of antioxidants can be harmful.

A long-term study showed that those who took vitamin A regularly were more likely to develop lung cancer than those who did not. A review of the 2007 trials suggests that "treatment with beta-carotene, vitamin A and vitamin E may increase mortality".

Vitamin C does not deserve the attention you give -

It will not help you overcome the cold and instead of eating a pile of grain, it is better to eat citrus fruits and strawberries. The "myth" of vitamin C began to assume chemist Linus Bolling in the 1970s, but it is actually an empty "fuss." Studies have shown that vitamin C does almost nothing to prevent colds.

In addition, large doses of 2,000 milligrams or more may increase the risk of kidney stones.

 Vitamin B3 - Over -

 It is better to take from the supermarket fillet racks salmon or tuna or plain beet. For many years, vitamin B3 has been used in high doses in the treatment of many problems, from Alzheimer's disease to heart problems.

But recent studies have led to an excessive prescription stop by doctors for this ingredient. A survey of 25,000 people with heart disease found that taking high doses of vitamin B3 to raise "good" cholesterol (HDL) did not reduce the incidence of heart attacks, strokes or deaths.

 In addition, patients enrolled in B3 were more likely than those who took placebo therapy with 

infections, liver problems and internal bleeding.

 Probiotics just eat yogurt Probiotics -

 expensive bacterial supplements that can cost more than $ 1 per pill - have become a large company with a market value of about $ 23.1 billion in 2012.

The idea behind it is simple:

Support trillions of bacteria that thrive in our intestines and play a crucial role in regulating health. But the introduction of this idea in real practice was a little more difficult. So far, the probiotic effect is still uncertain - sometimes helpful and sometimes does not help.

Therefore, it is best to take them as prescribed by the doctor, instead of running to the pharmacy on their own, snack of fermented milk products.

 Zinc eat it -

This is one of the special ingredients associated with the easing of the cold. Unlike vitamin C, which will not help cure colds, zinc can be really helpful. Minerals interfere with the recurrence of nasal viruses that cause colds.

In a 2011 study, scientists compared samples of people who had recently contracted the disease - one group had zinc and the other had a placebo.

The people who took the metal had a colder cold and fewer symptoms.

Vitamin E - Over -

 The increase in this vitamin is associated with an increased risk of certain cancers.

Instead of tablets, it is best to use spinach. Antioxidants have been circulated in vitamin E due to its ability to protect against cancer.

But the 2011 study, which included 36,000 people, showed that the risk of prostate cancer had actually increased among men who took vitamin E compared to those who took the placebo.

 A 2005 study linked high doses of vitamin E to the risk of large death. So, if you need more vitamin E, make yourself fresh spinach salad instead of ingested. Dark greens like spinach are rich in this ingredient.

Take folic acid if you are pregnant, or if you want to conceive.

 Folic acid is a vitamin B 9, which the body uses to create new blood cells and lower cholesterol. The US National Institutes of Health recommends that pregnant women, or those who want to get pregnant, should take 400 micrograms of folic acid daily, because their bodies require more of this component during fetal development.

 In addition, many large studies related to the addition of folic acid before and during pregnancy indicate a decrease in the frequency of neurological defects, and serious and life-threatening birth defects in the child's brain, spinal column, or spinal cord.
