If an adult is not lactose intolerant, having a habit of drinking milk appropriately can be a good lifestyle choice that helps with bone health, protein supplementation, and nutritional balance.

Especially after the mid-30s, bone density gradually decreases, so calcium-rich milk lays the foundation for osteoporosis prevention.

The main nutrients in a cup of milk (about 200 mL) are as follows.

  • Calcium 200-250 mg

  • About 7 g of protein

  • Vitamins B₂, D, potassium, phosphorus, etc.

Calcium and protein play a crucial role in bone health, muscle maintenance, and immune function support for men over 50.

Frequency and Recommended Amount

  • Having one cup every three days means consuming about two cups a week, which is an appropriate amount that is neither excessive nor insufficient.

  • According to the Korean Nutrition Society, the recommended daily calcium intake for adults is about 700 mg, so two cups of milk can easily provide about 400-500 mg per week.

  • The remaining calcium can be balanced by including cheese, tofu, spinach, and other foods in the diet.

Points to Note

  • If there are no symptoms like indigestion, abdominal bloating, or diarrhea after consuming milk, there is no particular cause for concern.

  • If there is occasional mild discomfort, it is advisable to switch to lactose-free milk or low-fat milk.

  • If you have kidney disease and need to limit protein and potassium, you should adjust your intake after consulting a doctor.

Expected Positive Effects

  • Reduced risk of osteoporosis through calcium supplementation

  • Prevention of sarcopenia and support for muscle recovery through protein intake

  • Relief of fatigue and promotion of calcium absorption through vitamins B₂ and D intake

  • Prevention of excessive snacking through hydration and satiety

Additionally, drinking milk in the morning or right after exercise increases protein absorption, which is more favorable for muscle recovery, and you can also expect synergy with vitamin D activated by sunlight exposure.

In conclusion, for a physically healthy adult, drinking a cup of milk every three days is not burdensome and can be considered a small investment in maintaining bone and muscle health.
