Is Red Wine Actually Good for You? How the Drink Affects Heart Health The New York Times

Some drinks are more dehydrating than others, but the amount of dry mouth you wake up with has more to do with alcohol volume, how much you drink per session, and what you combine with your favorite tipple. But, as Lindsey Pfau, M.S., R.D., points out, just one beer, for example, also has a lot of non-alcoholic fluids, which will help lessen the dehydrating effects of one beer. Egert et al. [127] evaluated changes in markers of oxidative stress following quercetin intake in 93 overweight or obese subjects aged 25–65 years. Quercetin is an important flavonoid present in high amounts in red wine and grapes. After 6 weeks, 150 mg/day of quercetin supplementation significantly decreased the plasma concentrations of oxidized LDL.

• Yet, other research has shown that drinking even a small amount of alcohol increases your chances.
• But because wine has a higher alcohol content than most types of beer, it’s more dehydrating than the latter.
• This is likely because of the interaction of sugar and water within the cells.
• According to the AHA, resveratrol may reduce blood pressure and increase high-density lipoprotein (HDL) cholesterol levels.

The depolymerization of the condensed tannins under oxidative conditions leads to the formation of proanthocyanidins. Flavan-3-ols and their precursor flavan-3,4-diols (leucoanthocyanidin) are the main components of condensed tannins in nature and can be found at concentrations levels from 1.2 to 3.3 g/L [78,87]. An ever-expanding amount of scientific evidence does red wine dehydrate you supports a protective role of habitual dietary intake of anthocyanins against age-related chronic conditions including CHD [79,80,81,82,83]. Several studies indicate that flavan-3-ols may exert cardioprotective actions, which might be due to the ability of flavan-3-ols to increase nitric oxide (NO) bioactivity and decrease superoxide production [72].

Dark-colored urine and low urine output

A 2017 review found that resveratrol may have protective effects against lung cancer in both human and laboratory studies. The mechanisms include preventing cell proliferation and tumor growth, inducing cell death in cancer cells, and inhibiting metastasis. This is partly because it creates toxins in the body, damages body tissues, and creates oxidation. This means that the potential adverse effects of alcohol may outweigh any benefit from resveratrol.

A 2020 study notes that dehydration may increase glucagon, a hormone used to maintain glucose or sugar levels in the blood. Lower levels of hydration in the body decrease the volume of the cells, which may impact a person’s blood sugar. Wine generally has a higher alcohol content than beer and cider, which may contribute to the likeliness of more frequent urination and dehydration. Serious dehydration can cause changes in your mental function, kidney failure, low blood pressure, and more. Red wine may have health benefits
The ancient Egyptians and Greeks considered wine to be “good for health” and used it as a form of medicine. Risk factors for severe dehydration included prolonged diarrhea or vomiting, extreme exercise, laxative use, burns, and certain medical conditions (2).

Prostate cancer

Over the last decade, a large amount of experimental and epidemiological investigations has supported the protective effect of flavonoids on cardiovascular and chronic degenerative diseases [61,62]. The main objective of this review is to summarize the various red wine components and their cardioprotective potential. In addition, we discuss the putative mechanisms and the chemical factors that influence the activity of the bioactive components of red wine.
