Protein coffee: trend or trap?

Coffee has always been a staple in morning routines around the world. But recently, a new hybrid drink has taken the health and fitness market by storm—protein coffee. Also known as “proffee,” this beverage combines caffeine with protein powder or ready-to-drink protein shakes. The idea sounds brilliant: get your morning energy boost while fueling your muscles at the same time. But is protein coffee really a smart choice, or is it just another marketing trend? The Promise of Protein Coffee Protein coffee claims to deliver a dual benefit. On one hand, coffee provides mental alertness, focus, and energy through caffeine. On the other hand, protein helps repair and build muscle, stabilize blood sugar, and promote satiety. By combining the two, brands market protein coffee as a time-saving super drink for busy professionals, gym-goers, and even weight-conscious individuals who want to maximize efficiency. Breaking Down the Nutritional Science The concept sounds appealing, but what do...

Protein for seniors: healthy aging

Aging is a natural journey, but how we age depends greatly on the choices we make—especially our nutrition. Among all nutrients, protein plays a starring role in supporting seniors’ independence, vitality, and overall health. For many older adults in Korea, traditional diets already provide a foundation, but specific attention to protein becomes essential with age. Let’s explore how protein fuels healthy aging and how Korean eating habits can be adjusted for long-term wellness. Why Seniors Need More Protein As people grow older, their muscle mass naturally declines, a condition called sarcopenia . Sarcopenia leads to weakness, higher risk of falls, and loss of independence. Protein intake helps preserve muscle, boosts recovery from illness, and strengthens the immune system. Research shows that seniors often need more protein than younger adults—around 1.0–1.2 g of protein per kilogram of body weight daily. In Korea, where rice-based meals dominate, seniors may unintentionally eat...

Low-Carb High-Protein Korean Diet: Fish, Eggs, Tofu, and Side Dishes for Weight Control

Low-carb, high-protein diets are among the most researched and popular strategies for weight control. While the Western version often emphasizes steak, chicken, or protein shakes, Korea offers a distinct and culturally rich adaptation. For centuries, Koreans have naturally eaten meals that are low in refined carbohydrates yet rich in protein sources such as fish, tofu, eggs, and fermented soy. This fusion of science and tradition provides not only effective weight management but also long-term health benefits that make the Korean approach highly relevant to global readers today. Why Low-Carb High-Protein Works The science behind this dietary approach is simple but powerful. Reducing refined carbohydrates prevents sharp spikes and crashes in blood sugar, while protein increases satiety and preserves muscle mass. Protein also has a higher thermic effect of food (TEF), meaning the body uses more energy to digest it compared to carbs or fats. This combination supports fat loss without t...

Protein and Intermittent Fasting: Science, Korean Foods, and Real-Life Tips

Intermittent fasting (IF) has become a global health trend, but one question often sparks confusion: does eating protein during a fasting window break the fast or ruin its benefits? The answer is more nuanced than a simple yes or no. While strict fasting means zero calories, many IF practitioners and scientists now recognize that strategic protein intake can enhance, not sabotage, the results—especially when weight management, muscle preservation, and metabolic health are the goals. Does Protein Break a Fast? From a purely biological perspective, yes—any calorie-containing nutrient technically ends a fast. Protein, like carbohydrates and fats, stimulates digestion and a metabolic response. However, research shows that the main health benefits of IF, such as improved insulin sensitivity, lower inflammation, and fat oxidation, are not completely erased by controlled protein intake. Unlike sugar, protein has a minimal effect on blood glucose spikes, and it can prevent excessive muscle ...
