Protein is especially important for those over 40... How should it be consumed?

Eating a lot of protein can put strain on the kidneys.

There is, about 1 gram per kilogram of body weight.

I should eat in moderation.

When you turn 40, signs of aging begin to appear in your body. Not only does your physical strength decrease, but faint wrinkles start to appear gradually on your previously smooth face. Muscles also begin to noticeably shrink.

Aging is inevitable, but it should not be neglected with the mindset that it cannot be helped. This is because a decrease in muscle mass can lead to various health problems. It reduces muscular endurance and increases the risk of falls, fractures, and osteoporosis. The basal metabolic rate also drops, causing weight gain even with less food intake, and this obesity can become a risk factor for various diseases. According to a 2014 study, after the age of 40, muscle mass tends to decrease by 1.5% to 5% annually. Therefore, if you are over 40, regardless of gender, you should pay special attention to the muscles that are losing mass. To prevent muscle loss, you must consume enough 'protein'.

To prevent muscle loss, it is important to consume enough protein with each meal. This is because protein plays a role in preventing the loss of muscle tissue. When protein intake is insufficient, our body breaks down stored muscle protein for use. However, by replenishing sufficient amounts of protein before it leaves the muscles, muscle loss can be prevented.

Generally, the recommended daily intake of protein is about 0.8 to 0.9 grams per kilogram of body weight. However, as people age, their digestive and absorption functions decline, so for the elderly, an intake of about 1 to 1.2 grams per kilogram is appropriate. However, excessive intake should be avoided. Overconsumption can stimulate insulin secretion, leading to conversion into fat, and can negatively affect kidney health. Nutritionist Jo Hye-ri from HiDoc Nutrition Counseling warned through HiDoc Q&A that "excessive intake of protein can be converted into fat and calcium is excreted in the urine," emphasizing the importance of maintaining an appropriate intake.
