Alcohol can significantly affect nutrition in several ways — both directly and indirectly. Here's how:
🧠 1. Empty Calories
-
Alcohol has 7 calories per gram — almost as much as fat (9 cal/g) — but no essential nutrients.
-
Drinking regularly can lead to weight gain without providing any real nourishment.
🧠 2. Impairs Nutrient Absorption
Alcohol can damage the lining of the stomach and intestines, reducing the absorption of:
-
B vitamins (especially B1, B12, folate)
-
Vitamin A, D, E, K (fat-soluble vitamins)
-
Minerals like zinc, magnesium, and calcium
🧠 3. Affects Liver Function
-
The liver helps store and activate nutrients. Chronic drinking can impair this, leading to nutrient deficiencies and metabolic issues.
-
It also prioritizes breaking down alcohol over processing nutrients.
🧠 4. Suppresses Appetite
-
Heavy drinking may lead to poor food choices or skipping meals altogether, reducing overall nutrient intake.
🧠 5. Blood Sugar Disruption
-
Alcohol can cause blood sugar crashes, especially when consumed without food.
-
This can affect energy levels, mood, and cravings.
Summary:
Alcohol affects your body’s ability to absorb, use, and store nutrients — leading to possible deficiencies, imbalances, and long-term health effects.
