A red wine labelled “heart” is more likely to contain a lower blood sugar level and a lower level of HDL cholesterol than a white wine labeled “heart”.
The labelling of red wine and white wine on the label has been hotly debated since the 1970s, with red wine producers and wine retailers claiming red wine is more healthful than white wine.
But a study published in the British Medical Journal (BMJ) suggests red wine might actually be less healthy than white wines.
The study was conducted by Dr Robert Brannigan, a professor of epidemiology at the University of Sheffield.
The researchers analysed data from more than 1,300 wine consumers from the UK, France, Italy and Germany.
They analysed the types of blood sugars and HDL cholesterol in the blood of 1,838 people over 18 months.
The researchers then divided people into groups based on whether they were consuming red or white wine, and compared their blood sugar levels with those of a control group.
The results showed red wine consumers had a lower number of beta cells (the protective cells in the heart that protect us from cardiovascular disease), while white wine consumers tended to have more beta cells.
The findings suggest that the consumption of red or red-branded wine could actually increase your risk of heart disease.
The research team, led by Dr Branniggan, say red wine has been associated with a lower risk of cardiovascular disease.
They say this could be because red wine’s high levels of antioxidants are linked to its ability to help fight infection and inflammation.
Dr Brannige says: “Our study shows that red wine consumption can have a direct effect on blood glucose levels.
It could also have a protective effect, because the protective effect of red wines may be related to its high antioxidant content.”
Dr Branyann says: “Red wine has also been linked with lower levels of the pro-inflammatory cytokine IL-1.
If you consume red wine, then the more inflammatory cytokines you have, the lower your risk for heart disease.”
He said the research is consistent with other studies that have found that red or high-risk red wine can actually lower blood pressure.
Dr David Jonson, who was not involved in the study, says:”It is not surprising that the effects of red and red-brand wines may have been linked.
Red wine has high levels in the antioxidant content and can help fight off infections and inflammation.”
The findings of the study also mean that red wines should be avoided in people with high blood pressure or a history of heart problems.
The study found red wine drinkers had a higher number of oxidised LDL (bad cholesterol) in their blood, which is linked to cardiovascular disease risk.
“The higher the number of oxidised LDL, the more atherogenic your heart is, which means it is more prone to heart attack and stroke,” said Dr Branyan.
“In red wine we are eating red and we are consuming the highest levels of antioxidant, and so that is the first thing we should be concerned about.”
It also means we are burning more red fat, which has been shown to increase your heart disease risk.
“The researchers say red wines might not be the only thing that may raise blood pressure, but it might be a contributing factor.
Dr Jonson says: “Red and white wines may also be responsible for raising the level of LDL in the bloodstream.
This may raise your risk.
In the study we found that the higher the levels of oxidisation in the red wine were, the higher their LDL levels were, and this might have contributed to their higher blood pressure.
“What can red wine do to you?
The authors say red and white have different effects on the body.”
Red wines are also known to increase HDL cholesterol, which may help reduce blood pressure and may be associated with an increased risk of the type 2 diabetes.””
In contrast, a low red wine level could decrease the levels in your body and therefore the level and level and amount of oxidizable LDL in our blood.”
Red wines are also known to increase HDL cholesterol, which may help reduce blood pressure and may be associated with an increased risk of the type 2 diabetes.
“Dr Jonty Hough, who is a wine consultant at the Royal College of Surgeons, says the study is interesting but not conclusive.
He said: “The results show that red and high-quality red wine may be less unhealthy than other types of wine.”
But it is important to be aware of all of the risks associated with drinking red and low quality red wine.””
Red or high quality red and wine may have a beneficial effect on your health, but the actual amount of benefit that comes from drinking red wine should be assessed on a case-by-case basis.”
The British Heart Foundation says red wine contains no harmful chemicals and is good for the heart.
