Carbohydrates are one of the three macronutrients in our diet, along with protein and fat. They are organic compounds made of carbon, hydrogen, and oxygen, and are primarily responsible for providing energy to the body.

Let’s explore what scientific research says about the ideal protein intake for healthy adults . Recommended Protein Intake (RDA) According to the World Health Organization (WHO) and the National Academies of Sciences , the Recommended Dietary Allowance (RDA) for healthy adults is: 0.8 grams of protein per kilogram of body weight per day That means: A 60 kg person needs about 48 grams/day A 70 kg person needs about 56 grams/day This amount is enough to meet the basic needs of most healthy adults and prevent deficiency.  When You May Need More Protein In some situations, your body requires more protein than average: Group   Recommended Intake Purpose Physically Active...

How to select a topic for Scientific research?

-
  🔹 Step 1: Identify Your Area of Interest Ask yourself: Which subject or field excites me most (e.g. Public Health,nutrition, health systems)? What issues or questions do I often encounter in my teaching or clinical practice? Which topics align with my long-term goals (e.g. publication, grant, or thesis)?  Example: If you teach Health, possible broad areas could be: Non-communicable diseases prevention Health education methods Maternal and child health Environmental or occupational health Health system challenges in a country  🔹 Step 2: Review Current Literature Look for: Recent papers (last 5 years) in your area. Gaps — what questions are not yet answered or only partially studied? Contradictions in findings that need clarification.  Tip: Read abstracts of papers in journals like American Journal of Public Health or BMC Public Health to get inspiration. 🔹 Step 3: Focus and Narrow It Down Avoid topics that are too broad.

Caffeine Consumption: What Science Tells Us

-
Image
  Caffeine Consumption: What Science Tells Us Caffeine is the most widely used psychoactive substance globally. It’s found in coffee, tea, chocolate, energy drinks, some sodas, and even certain medications. While many of us consume it daily for alertness or enjoyment, its effects are complex and vary greatly depending on dose, individual sensitivity, timing, genetics, and other factors. How Caffeine Works Mechanism of action : Caffeine primarily acts by blocking adenosine receptors (especially A1 and A2A) in the brain. Adenosine is a neuromodulator that promotes sleep and relaxation; when its effects are inhibited, alertness increases and feelings of tiredness are reduced. Metabolism : The liver, via cytochrome P450 enzymes (especially CYP1A2), is responsible for metabolizing caffeine. Genetic variations in these enzymes mean that people differ in how quickly they clear caffeine. Slow metabolizers are more likely to experience prolonged effects.  Potential Benefits of ...

-
Image
  Adaptogens are natural substances (mostly herbs and some mushrooms) that help the body adapt to stress (physical, emotional, or environmental) and restore balance in the body. Definition The term adaptogen was first introduced in the 1940s in Russia. For a substance to qualify as an adaptogen, it should: Increase the body’s resistance to stress. Help normalize body functions (not overstimulate or suppress). Be safe and non-toxic with long-term use. How They Work (Mechanism) Adaptogens don’t work like drugs that target one system directly. Instead, they act broadly on the neuroendocrine-immune system (the interaction between the brain, hormones, and immune response). Key ways they work: Regulate Stress Hormones Adaptogens modulate the HPA axis (hypothalamic–pituitary–adrenal axis) . This helps balance cortisol (the stress hormone). Too much cortisol causes anxiety, poor sleep, weight gain, while too little causes fatigue. Improve Cellular Energy ...
