Wine is closely linked to the Mediterranean diet, which is considered one of the healthiest diets globally. This alcoholic beverage is produced via the fermentation process of grapes and typically contains around 14% pure ethanol. Red wine is rich in polyphenols, which may possess cancer-inhibiting properties.
Nutritional value of wine
Wine is primarily composed of two substances: water and ethanol. The caloric content depends on the amount of simple sugar, hence sweeter wines have more calories per 100 grams than dry wines. Wine contains elements such as potassium, phosphorus, magnesium and small amounts of iron, zinc, manganese, and copper. The nutritional value per 100 grams of product is as follows: - Calorie: 68 kcal, - Protein: 0.1 g, - Fat: 0 g, - Carbohydrates: 0.2 g, - Fiber: 0 g. Macro- and micronutrients: - Sodium: 7 mg, - Potassium: 110 mg, - Calcium: 7 mg, - Phosphorus: 13 mg, - Magnesium: 11 mg, - Iron: 0.9 mg, - Zinc: 0.1 mg, - Copper: 0.06 mg, - Manganese: 0.1 mg, - Iodine: 35 µg. Vitamins: - Riboflavin: 0.01 µg, - Niacin: 0.01 µg, - Vitamin B6: 0.02 µg.
Which one: Red or White?
Red wine, when compared to white wine, contains a significantly larger amount of antioxidants and health-promoting compounds, such as resveratrol, which is present in the skin of dark-red fruits. Additionally, it contains more potassium (an average of 50 mg/100 g), phosphorus (a mean of 5 mg/100g), magnesium, iron, and sodium. On the contrary, white wine provides more carbohydrates (0.4 g/100 g) and calcium (2 mg/100 g).
Sweet or sour?
A sweet wine will contain a higher amount of sugar in comparison to an acidic wine. Therefore, it's recommended to have as few simple carbohydrates as possible in your dinner lamp. Additionally, if we opt for acidic red wine, we'll provide our body with valuable flavonoids that can offer protection against atherosclerosis.
The Mystery of the French Lifestyle
Globally, nutrition specialists stress that alcohol consumption should be restricted solely to exceptional situations and minimal amounts. Contrary to this, the French display a wholly distinct approach. In their country, it is customary to consume red wine during meals, and this tradition is linked with a beneficial impact on the cardiovascular system. Red wine contains resveratrol, which eliminates free oxygen radicals and reactive nitrogen radicals. This substance safeguards the brain and nerve cells, further decreases blood platelet aggregation, and lessens the probability of blood clots.
Advantages for sleep
In 2018, research found traces of melatonin in wine. This hormone is manufactured in the pituitary gland and released during the night. It is responsible for enhancing circadian rhythms of sleep and alertness, which are also dependent on factors such as glucose levels or the immune system. Researchers believe that consuming around 125 ml of red wine may affect the melatonin level in the blood, which could bring positive effects for improving sleep quality.
Hypersensitivity to red wine
Red wine contains histamine, which can result in undesirable consequences in certain individuals - skin flushing, a sensation of vertigo, spasms of the digestive tract muscles or a drop in blood pressure. Even top-quality alcoholic beverages of this kind contain sulfites, which can also contribute to the manifestation of the previously mentioned symptoms.
Utilization of Wine
Wine, although primarily consumed for relaxation purposes, also has other applications. Enology, the science of wine, also investigates the interactions that occur between food and wine. Often, food accentuates the aroma and intensifies the flavor present in a certain wine. Wine can be the basis for an unusual dish with forest berries and can also be used in Italian risotto. Interestingly, marinating beef in wine before frying reduces the negative effects of oxidation processes that occur during heat treatment.
