In modern-day life, information on health is easily available. A person is one minute away from knowing about the best diets and supplements. This is due to the many advantages of the internet and social media.
Anyone from a teenager to an older adult can read on what is best for him or her. As a consequence, some diets and supplements are now more popular than ever. These include the ones specific to weight loss, health conditions, and muscle gain.
At the same time, there is also higher levels of research on common diets and health supplements. While some studies show they are beneficial, others do not agree.
In fact, research also highlights the many negative effects of following prevalent diets. Many people also know about how the long-term outcomes of many diets and supplements are harmful.
However, many still continue to follow many of such trends to this day. Secondly, research now also shows that some of the ‘healthy’ dietary changes and additions may also not be that good.
It is a common assumption that taking supplements can improve health. Consequently, many people take a number of them in order to ‘protect’ their organs. Research now shows that taking these medicines may actually have no effects.
For example, a meta-analysis from a collaboration of researchers corroborates the same view. The institutions in the study were West Virginia University, John Hopkins School of Medicine, and Mayo Clinic.
The findings of the study appear in the journal Annals of Internal Medicine. The leading author of the study is Dr. Safi Khan.

What Was the Research Methodology?
Dietary supplements are becoming more and more common with the passing time. Many people now stick to them to provide them with essential nutrients. This is also because the Standard American Diets do no provide them.
Instead of getting the nutrients naturally from food, people rely completely on the supplements. In addition, many people choose to take them since they believe it may improve their health.
This is the main reason why a meta-analysis on popular diets and supplements was necessary. In order to do the analysis, the researchers looked at data from 277 trails. This was information on nearly one million participants.
The main focus of the study was the effects of different supplements on cardiovascular health. The researchers then took eight diets and sixteen other supplements into consideration.
The supplements were as follows: antioxidants, vitamins A, B-3, B complex, C, E, D and B-6, selenium, folic acid, beta-carotene, multivitamins, calcium, omega-3, iron, and calcium plus vitamin D.
The dietary interventions were as follows: increase in intake of omega-3, Mediterranean diets, reduction in saturated fats, modified dietary fat, increase in intake of omega-3 alpha-linolenic acids, reduction in dietary fat, and reduction in salt intake.
What Was the Result?
After the observation of the trials, the researchers saw that some of the diets were beneficial. For example, low-salt diets led to a reduction in premature deaths. Similarly, higher consumption of omega-3 was good for preventing heart disease.
On the other hand, some diets and supplements had no effects at all. Most of the supplements did not in fact help in protecting cardiovascular health. Diets such as Mediterranean diets and changing fat intake also had no effects.
Though the findings are limited, the researchers state that it paves a way for further research on supplements and diets. It may add to the information on both in the coming future.
