Think of carbohydrates as the fuel that powers your body, much like gasoline propels a car forward. These macronutrients consist of sugars and starches intricately woven together, serving as the primary energy source for your body's daily activities. Stored in muscles and the liver as glycogen, carbohydrates ensure a steady reservoir of energy, even if you miss a meal or two. Upon consumption, they are diligently broken down into glucose, the preferred cellular currency for energy. You'll find carbohydrates generously distributed throughout fruits, grains, rice, legumes, and a diverse array of vegetables, including potatoes, yams, and corn.
These include meat, seafood, legumes, nuts and seeds, eggs, milk products, vegetables.
4 calories in a gram of protein
Proteins stand as the architectural backbone of your body, providing the essential building blocks for cells and tissues. During digestion, proteins are transformed into amino acids, which play pivotal roles in growth, development, tissue repair, and maintenance. Beyond this, proteins bestow structure upon muscles and bones, and they step in as repair agents when tissues suffer damage. For instance, the skin boasts the presence of keratin, a protein that hardens and heals damaged skin cells. The sources of protein are manifold, encompassing beef, pork, chicken, fish, beans, eggs, and dairy products. It's worth noting that not all proteins are created equal; animal proteins tend to exhibit higher bioavailability, making them more efficiently absorbed by the body.
