Prevenir problemas cardio vasculares

Las vitaminas no sirven para prevenir problemas cardiovasculares:

Major studies prior to 2013 that looked at cardiovascular risk and multivitamin supplementation

One must question if the three new 2013 studies were consistent with previous studies that evaluated multivitamin supplements for cardiovascular risk reduction. Two of the largest previous studies reported prior to 2013 were the Women’s Health Initiative (WHI), which was a large cohort study of 161,000 women who were followed for 8 years. The WHI did not show any reduction in cardiovascular risk with multivitamin supplementation (Neuhouser, 2009).

Another large, prospective, randomized clinical trial of Vitamin E supplementation was reported in 2000, called the Heart Outcomes Prevention Evaluation Study (HOPE). This Canadian trial enrolled 2,545 women and 6,995 men aged 55 or older and randomized them to receive 400 IU of Vitamin E vs a placebo for a mean follow-up of 4.5 years (Yusuf, 2000). The results of the HOPE trial showed no statistically significant differences in cardiovascular events or deaths from cardiovascular events in the two arms of the study. The HOPE trial was then extended as the HOPE-TOO trial, which followed 3,994 of the initial patient group who agreed to extend their participation for a mean follow-up of 7 years (Bosch, 2005). The results of the HOPE-TOO trial showed difference in cardiovascular events between Vitamin E and the placebo, but in the Vitamin E group, there was a statistically increased risk of heart failure (RR = 1.13) and hospitalization for heart failure (RR = 1.21).

Conclusion: Old and new studies (2013) consistently show no cardiovascular disease benefit

In conclusion, the WHI study, the HOPE trial, the HOPE-TOO trial, the two meta-analsyis studies from 2013, as well as the Physicians Health Study II all showed the same results. The use of a multivitamin supplement does not reduce your risk of heart disease.

Pero las frutas y verduras si lo hacen:

On the contrary, all of the researchers involved in these studies emphasize that there is clear, convincing evidence that fruits and vegetables do reduce your risk of cardiovascular disease (Hung, 2004). As Lock said so clearly a few years ago, “if an individual increases fruit and vegetable intake up to 600 gms daily, the worldwide burden of cardiovascular disease could be reduced by 31% for ischemic heart disease and 19% for ischemic stroke”(Lock, 2005). In summary, of all of these researchers agree that you should buy lots of fruits and vegetables for your heart, not supplements for your heart.

Luego vienen las conspiraciones de que la Big Pharma… bla bla bla…. Los grandes estudios que desacreditan productos de la Big Pharma existen y estan ahi… Pero ojo que hablamos de Multi-Vitaminas y de muchas en su conjunto, y eso es muy generico!

Una persona que consuma muchas verduras y frutas no necesita tomar multi-vitaminicos en general, pero….
– Curcuma, te verde, resveratrol etc… Tienen grandes beneficios via epigenetica, no los confundamos con las vitaminas. (www.buscandolalibertad.com/suplementos- … 14-20.html)
– La vitamina D es otro caso, es mas bien una hormona y tiene que ver con lo que se toma el sol, esa vitamina es extremadamente importante. (suplementos-vitaminas-f114/vitamina-t1515-20.html)
– Los beneficios de otras formas de Vitaminas como los precursores de NAD+ estan siendo demostrados. (www.buscandolalibertad.com/salud-f106/l … html#p8870)
– Determinadas personas con genotipos especificos necesitan vitaminas extra como metilfolato o metilcobalamina. (genes-f119/mthfr-t1673.html)

Aqui tenemos un comentario al respecto:

The research studies behind the stories related below are basically concerned with longitudinal and large-population impacts of vitamin, multi-vitamin and essential mineral supplementation. In interpreting these studies, it is important to keep certain distinctions in mind: 1. While vitamins can be packaged in dietary supplements, many very important dietary supplements are not vitamins, e.g. curcumin, green tea extract, resveratrol, fish oil). It is fallacious to damn vitamin and mineral supplements for not making a difference and then go on to say that all dietary supplements are useless, as is common in the general press. 2. Some vitamins like Vitamin D clearly do make a difference for health as documented by ample other research (actually vitamin D might better be classified as a hormone). 3. Many phyto-substance dietary supplements like curcumin and resveratrol have been broadly and falsely marketed as “antioxidants,” but they in fact primarily operate via epigenetic mechanisms. And many “antioxidant” supplements like alpha-lipoic acid and melatonin were not included in these reported studies; further. they exercise their main benefits via other pathways than direct suppression of ROS. 4. Comparing taking vitamins against eating fresh fruits and vegetables is significant in only one respect. You can’t get the benefits of eating fruits and vegetables from consuming vitamins and minerals because these last substances don’t contain plant-based polyphenols! But you may be able to get some and even more of the benefits of eating fresh fruits and vegetables by consuming other supplements such as green tea extract, resveratrol and curcumin. Back to Jim;s points: I do agree with the general observation that multivitamin and mineral supplementation does not make sense for healthy people who consume well-balanced diets.
