Red wine benefits?

I’d love to believe that the resveratrol in red wine possesses a range of health benefits including anti-cancer effects, anti-inflammatory effects, cardiovascular benefits, anti-diabetes potential and protection against Alzheimer’s. Thus good for all adult ages. A glass of wine a day might keep the doctor away.

But it might be wishful thinking. It is true that resveratrol can inhibit growth of cancer cells in a culture and in some animal models, but it is not known whether it can prevent cancer in humans. It has increased the lifespans of yeast, worms, fruit flies, fish, and mice fed a high-calorie diet, but again this has not been shown in humans. So the brutal truth is probably that the amount of resveratrol in red wine is too small to have any measurable beneficial effects in humans.

But we can still believe!

Whisky benefits?

I’d love to believe that the ellagic acid content of whisky actually can reduce oxidative stress. Ellagic acid has been shown to have antiproliferative and antioxidant properties in a number of in vitro and small-animal models. It may directly inhibit the DNA binding of certain carcinogens, and it has a chemoprotective effect in cellular models.

But again it might be too good to be true. Ellagic acid has been marketed as a dietary supplement with a range of claimed benefits against cancer, heart disease, and other medical problems. In 2008, the U.S. Food and Drug Administration called it a fake cancer ‘cure’ consumers should avoid. So not much luck there.

But we can still believe!

It might actually be premature to give up red wine and whisky completely. As antioxidants, like resveratrol and ellagic acid, are additive any contribution is useful. Complement the spirits with plenty of berries, dark green vegetables and nuts and you will not go wrong. Red wine and whisky will be outdone on the health front, but so what.

But there is more…

chilipeppers

Red chilli pepper benefits?

I’d also very much love to believe the latest reports that consumption of hot red chilli peppers can reduce deaths due to heart disease or stroke. Going back for centuries, peppers and spices have been thought to be beneficial in the treatment of many diseases. A new study using National Health and Nutritional Examination Survey (NHANES) III data collected from more than 16,000 Americans who were followed for up to 23 years, found that hot red chilli pepper consumption decreased mortality by 13%.

But unfortunately the findings, widely published by the popular press, are based solely on epidemiological data. Exploring epidemiological data, even if prospective in nature, is fraught with obstacles. The authors themselves point out that given the observational nature of the investigation, causality can only be suggested, not confirmed.

However, on the bright side there is some support for the findings in a theory that capsaicin in chilli peppers can influence cellular and molecular mechanisms that prevent obesity and modulate coronary blood flow, and also possesses antimicrobial properties that may alter the gut microbiota.

In a sign of our desperate need to find some beneficial news the popular press was inundated by citations of the positive findings. Some examples:

  • “Can eating spicy food lead to a longer life? Chili peppers could be the secret” says National Post.
  • “Spicy food could be the secret to a healthy heart and a longer life, says new study” says The Telegraph.
  • “This Is Your Body On Spicy Foods” says The Huffington Post.
  • “Eat Peppers, Live Longer?” says New York Times.
  • “Red hot chilli peppers: the way to a longer life?” says The Sydney Morning Herald.

If you’re on to a good thing the press will pick it up. Doesn’t mean it’s true though. But we can still believe!
