Vinegar & health
Vinegar has long been known for its exceptional medicinal properties, focusing on its greatest health benefits
Diabetes is an important health problem in our society and there is a close link between the risk of develop type 2 diabetes and overweight. Until now, the acquisition of healthy habits is the best way to protect yourself against diabetes. In addition, some foods that are characterized by a lower glycemic index, that is to say which allow to reduce the rise in blood glucose levels as a result consumption, could also be interesting in the prevention and treatment of diabetes. On this subject, some studies show that adding some amount of vinegar (about 15 ml to 30 ml) at a meal containing carbohydrates would decrease the response glucose and insulin in the blood 30 to 60 minutes after eating the meal. Everything leads to believe that the acetic acid present in the vinegar would be the origin of the effects observed, since an increase in the proportion of acid acetic acid in vinegar brings about a greater reduction in blood sugar and insulinemia1. Acetic acid would allow the inhibition of the enzymes responsible for digestion of disaccharides in the small intestine, which would reduce their digestibility and their absorption. In addition, the consumption of acetic acid increase the use of glucose by the human body.
With respect to dietary intake, studies demonstrate also that adding vinegar would bring a greater feeling of fullness after the meal, suggesting a reduced calorie intake to longer. The attenuation of the glycemic response and the increase in satiety after a meal are therefore interesting effects vinegar used as a condiment. However, studies additional information is needed before stating that the vinegar consumption can prevent and treat diabetes type 2 as well as promote weight loss.
Hypertension is a health problem that is partly responsible for arteriosclerosis and some cardiovascular illnesses. A study in rats hypertensive indicates that daily consumption of vinegar would be associated with a decrease in blood pressure. Indeed, acetic acid vinegar would reduce pressure blood and renin activity, a vasoconstrictor enzyme. This enzyme is thought to be responsible for producing peptides that cause hypertension. The authors of the study, however, do not specify the amount of vinegar required to observe these results. Thus, clinical studies will be necessary before applying these results to humans and to determine the optimal amounts of vinegar to consume. However, to date, no human studies have been conducted to evaluate the impact of vinegar consumption on arterial hypertension. These results therefore remain preliminary.
Many studies indicate that the antioxidant-rich diet could be an important element in the prevention of neurodegenerative diseases. In this respect, wine vinegar would be considered as a good food source of antioxidants because it contains approximately 600 mg / l of phenolic compounds. Since these antioxidants would intervene in the neutralization of free radicals of the human body and in protecting the tissues against oxidative stress, 9 wine vinegar could therefore possibly play a protective role against some neurodegenerative diseases such as Alzheimer's disease or Parkinson's disease.
A study in China of a population with a high incidence of esophageal cancer10 shows that vinegar consumption has a protective effect against this type of cancer. However, several factors that may have an impact on the development of esophageal cancer have also been highlighted in this population (poverty, type of water consumed, etc.). Note that no precision is provided by the authors of the study as to the amount of vinegar associated with this protective effect.
Antibacterial effect of vinegar for the care of the ears
The high acidity of vinegar makes it a very good antibacterial. The antibacterial effect does not have the same effectiveness for all types of bacteria. A team of researchers12 verified by cell culture the effectiveness of acetic acid on the growth of various bacteria causing the most common earaches (Pseudomonas, Staphylococcus, Proteus). Acetic acid has been shown to be very effective and its external use could possibly be an interesting alternative to the antibiotic treatments currently used.
