The red wine benefits for health is one of the most debated topics in the health forums for many years.
A glass of red wine as part of the daily diet is considered to be very healthy by many, but some others say the expected benefits from wine are over-exaggerated.
However, a number of studies have shown that specific ingredients in grape wine have the efficiency to prevent and cure several diseases, especially cardiovascular diseases.
But it must be noted here that excess consumption of wine, especially those with higher alcoholic content, is going to harm the body severely in the long run than rendering any benefits.
In this article, we shall briefly discuss all details of red wine; both health benefits and side effects.
What Is Red Wine?
The term ‘wine’ could generally mean an alcoholic drink.
The red wine is made from the must or pulp of red or black grapes. For this, the whole grapes (together with skin) are crushed and fermented for 5 to 14 days, and finally, the fermented juice is strained and bottled.
The red color is usually got from the skin of the grape.
White wine is made by fermenting juice which is made by pressing crushed grapes to extract the juice; the skins are removed after crushing the grapes themselves.
The level of alcohol present in all-natural red wine ranges between 11.5% to 15%. The alcoholic content is minimal, but consuming more than 2 glasses of wine will add up to a good bit of alcohol in the body.
There are many varieties of grape wine with differences in color, taste, and level of alcohol present in them. These differences arise because the grapes cultivated in different geographical regions differ in quality and kind.
The major health benefits of the wine are derived from the powerful antioxidants and the moderate level of alcohol present in it.
How Many Calories In A Glass Of Red Wine?
You may be just wondering how many calories are in a glass of red wine, and it is important to know for those who are on a strict low-calorie diet.
Nutritional and alcoholic values of 100ml (117gm) red wine in percentage are as follows:
- Calories 85
- Protein 1
- Carbohydrate 1
- Fat 0
- Fiber 0
- Alcohol 11 – 15
One serving (one glass) of red wine is usually 5 fl oz (125ml/147gm), and it contains approximately 107 calories.
One large glass of wine (250ml) contains 214 calories.
The Reason Behind Red Wine’s Popularity
Several health studies have time and again vouched for the health benefits of red wine for one undeniable reason.
It is observed that the lowest rate of heart diseases is present among the French. Their diets, in general, are not the best as their favorite foods generally contain a lot of saturated fat and cholesterol.
The only reason for ‘healthy heart’ in most French people is believed to be their love for red wine.
Red wine is a part of the daily diet among most French. The health experts feel that the antioxidant properties of the wine are responsible for fighting the bad effects of LDL cholesterol and keeping them healthy.
Of course, red wine has some added health benefits. But some of the studies refute these claims and suggest that the French habit of eating whole-grain foods is the major reason behind the healthy heart among them.
Red Wine Has Plenty Of Antioxidants
Many cardiovascular diseases and cancer are associated with the oxidative damage that happens to the body. The oxidative damage in the body can be well taken care of by the proanthocyanidins antioxidant.[6, 7]
Resveratrol is a polyphenol-type substance that can protect the lining of blood vessels in your heart.
Some coronary diseases are caused by blood clots. Resveratrol is an excellent antioxidant that can remove the chemical that causes a blood clot.
It is expected the regular consumption of a glass of red wine will reduce the possibility of stroke by preventing the clotting of blood.
Resveratrol tested on animals indicated an increase in longevity of life.
This key antioxidant in the wine also reduces the low-density lipoprotein (LDL) cholesterol (bad cholesterol), and this helps in improving the heart’s health and prevents high blood pressure to some extent.
However, some of the experts negate these claims as they say that red wine contains only a very little amount of resveratrol that is not sufficient enough to produce the expected health benefits unless a person drinks several liters of red wine a day.[9,10]
Benefits Of Red Wine For Healthy Heart
It is customary for people in some of the European countries, more popularly in France, to have one or two glasses of grape wine before dinner.
It is expected that moderate amounts of red wine give good health benefits in comparison to any other alcoholic drink.
Some studies indicate people who drink about 5 ounces of red wine a day have a 30% lower risk of contracting cardiovascular diseases.
As per some other study results, even people already with heart diseases could also benefit a lot by beginning to drink a moderate amount of red wine daily.
Other Health Benefits Of Red Wine
Red wine is not only good for the heart but also, it has good health benefits in preventing and curing various other diseases.
Below given are some of the best-known health advantages of drinking grape wine as a regular diet:-
- Helps in reducing the risk of colon cancer, ovary, prostate cancer, and basal cell cancer[22,23,24]
- Helps in reducing the risk of developing Alzheimer’s disease and dementia[25,26]
- Helps in reducing the risk of plunging into depression and hypertension[27,28]
- Aids in reducing insulin resistance when two glasses of red wine are consumed per day for 4 to 5 weeks.[29,30]
- Helps in reducing the risk of Type 2 diabetes in woman
- Aids in preventing excess weight gain as piceatannol found in grape wine block cellular processes that allow fat cells to develop and grow. But an excessive amount of red wine consumption can have a reverse effect as it contains a lot of calories.
- Useful for protecting teeth from the cavity as red wine could kill dangerous bacteria in your mouth
Possible Side Effects
Just like any food, red wine consumption in excess amounts is also going to have adverse effects on health.
Drinking excess amounts of red wine with normal alcoholic content can gradually drive the individual to become an alcohol addict. It will not only destroy health but will destroy social and family relationships too.
Many of the physicians and health experts deliberately do not recommend grape wine as a healthy diet in fear of people falling prey to alcohol addiction.
Some of the possible side effects of excess red wine consumption are as follows:
- Regular consumption of grapes will lead to alcohol dependence.
- Drinking more than two glasses of regular red wine consumption can lead to the development of liver cirrhosis as more than 30 grams of alcohol are present in it.
- Like every alcohol addict, red wine consumers could go into depression with excess consumption of this drink.[36,37]
- Red wine is rich in calories, and too much of it will lead to unwanted weight gain even though a moderate amount is good for weight loss.[38,39]
- More than two glasses of red wine will add up more than the healthy limit of alcohol, which would cause diabetes and premature death through organ failures.[40,41]
How Much Red Wine To Drink A Day?
Anyone can drink red wine moderately and experience its health benefits without the fear of any side effects.
Most commonly accepted and followed the amount of red wine consumption as follows:
- 1–1.5 glasses a day for women.
- 1–2 glasses a day for men.
It is good to have a moderate amount of red wine five days a week for the best benefits and without becoming an alcohol addict.
However, you should not be taking red wine if you are in the habit of having regular alcohols like whiskey, rum, etc. It is also not recommended for people who have a previous history of substance abuse as it can rekindle the old habits in them.
The Bottom Line
Despite red wine being linked to a few health benefits, many of the experts do not recommend it as a healthy diet.
It is really not worthy enough to encourage the intake of any type of alcohol for the sake of little health benefits.
It is actually for the antioxidants’ sake this drink is labeled as healthy. Actually, a glass of red wine contains only a very little amount of resveratrol and other antioxidants; it means a person needs to drink several glasses of wine to get some benefits from these antioxidants.
There are so many other natural foods that contain more amounts of antioxidants than red wine.
However, if you already have red wine as a principal part of the food culture in your country, it is good to carry on with the drinking of red wine in a moderate amount.
