Nutrition Facts: Calories & Carbs

A standard serving of a can or a bottle of beer (12 fluid oz/360g) contains 155 calories and 12.8 grams of carbohydrates. There are light beers available for the calorie-conscious. A can of light beer, according to the USDA, has 104 calories and 5.9 grams of carbs. [2] [3] [4]

While red wine is often considered the “healthy” option due to the presence of antioxidants, a Harvard report says beer contains similar phenolic compounds as wine. However, they are in small amounts in beer, including quercetin, epicatechins, and gallic acid. A majority (70-80%) of the polyphenols come from barley malt and the rest from hops, the flowers of the hop plant. Beer also has a larger protein amount than wine. [5] [6] [7]

Alcohol Content (ABV)

The 2015-2020 Dietary Guidelines for Americans defines a standard serving of beer as 12 ounces and 5% ABV. However, the alcohol content for beer can range between 2.5 to 25% ABV. Furthermore, light beers usually contain almost as much alcohol as regular beer – about 4.2% ABV. It is best to check the alcohol content on the bottles before drinking. [8] [9]

Health Benefits

Health benefits of beer become prominent if it is consumed in moderate amounts. Some of them include the following:

Protects Heart

Beer contains vitamin B6, which protects against heart diseases by preventing the build-up of a compound called homocysteine. It has a thinning effect on the blood and prevents the formation of clots, which cause blockages in the coronary arteries. According to a study conducted by ICTAN Spain, moderate consumption by healthy Spanish adults during 1 month was linked with positive blood lipid profile changes. Moderate consumption also reduces the risk of inflammation, the root cause of atherosclerosis, which is cholesterol and plaque building upon the blood vessels, and artery walls. [10] [11]

Controls Diabetes

Studies have linked moderate beer consumption to a lower prevalence of type 2 diabetes. According to a study carried out by the Harvard School of Public Health, moderate intake of beer can reduce the risk of developing type 2 diabetes in middle-aged men. It was found effective for occasional drinkers who kept their consumption at one or two servings of beer, wine, or liquor in a day. [12]

Prevents Anemia

Beer contains iron, vitamin B12, and folic acid, deficiency of which may lead to anemia. A study conducted at the University of Valladolid, Spain, has found that iron content in dark beer is more than compared to pale or non-alcoholic beer. Another study published in Alcoholism: Clinical and Experimental Research journal found that low-level alcohol consumption could increase levels of ferritin in the body, which in turn could lead to increased iron stores. [13] [14]

Delays Aging

Beer increases the potency and impact of vitamin E, which is a major antioxidant in the body. It is an important part of the maintenance of healthy skin, while also slowing down the aging process.

Prevents Kidney Stones

While intake of water is the best way to deal with kidney stones and prevent them, moderate consumption of beer might also help with kidney stone prevention, says a study published in the Medicine journal. [15]

Aids Digestion

Alcohol in beer can lead to diarrhea in some. In others, however, beer could help the digestive system function more efficiently. This could help with constipation. [16]

Stress Buster

Like other alcoholic drinks, beer is shown to reduce stress and facilitate sleep.

Diuretic Quality

Beer acts as a diuretic and significantly increases urination. This facilitates the increased removal of toxins and waste materials from the body.

Cleanses Gastrointestinal Tract

Beer is a good source of soluble fibers that promote general health. This includes being good for the heart, as well as helping to clean out the digestive tracts.

Limited consumption also ensures that the calorie intake from it does not affect the health adversely. [17]

Risks & Side Effects

Drinking in excessive amounts (addiction) is dangerous to health and can negate any and all beneficial effects. Some short-term side effects on excessive beer consumption include: [18]

  • Slurred speech
  • Vision impairment
  • Lack of coordination
  • Mood swings
  • Memory lapses

According to the Centers for Disease Control and Prevention, people who should not drink alcohol include women who are pregnant, individuals younger than 21 years of age, and people who are recovering from alcoholism or cannot control the amount they drink. Also, it should be avoided by people who are planning to drive or any other activity that required focus and skill.
