Nutrition 101 from a Scientific Point of View in Simple Words
My perspectives on using food for health and well-being as a retired health scientist
Nutrition involves the intricate process by which living organisms secure and utilize substances essential for their growth, maintenance, and repair. It’s essentially the study of nutrients — those vital molecules that the body relies on.
Breaking it down, we have macronutrients like carbohydrates, proteins, and fats, each playing a distinct role. Carbs are our go-to energy source, proteins are the builders and repairers, and fats provide concentrated energy and contribute to cell structure.
Micronutrients, namely vitamins and minerals, are our unsung heroes, ensuring various bodily functions run smoothly.
Now, let’s clarify some terms.
Digestion is the breakdown of food into smaller, absorbable components, orchestrated by organs like the stomach, liver, and intestines. Absorption, the next stop, involves the uptake of nutrients into the bloodstream for transportation to different corners of the body.
Metabolism is a cellular maestro, managing chemical processes to keep the show on the road. It converts nutrients into either energy or building blocks for growth and repair.
