Proteins are vital for muscle repair as they are the main building blocks of body tissues. They break down into amino acids, which repair muscle damage, support recovery, and contribute to the growth of muscle mass. This is particularly important after exercise or any physical activity that strains muscle tissues.

Fiber aids digestion by adding bulk to the stool, which helps keep bowel movements regular and can prevent constipation. It also helps to keep the gut healthy and can reduce the risk of digestive conditions like intestinal ulcers, hemorrhoids, and diverticulitis. Furthermore, fiber-rich foods can aid in weight management by making you feel fuller longer.

Iron is crucial for the production of red blood cells, which carry oxygen from the lungs to the rest of the body. It forms part of hemoglobin, the protein in red blood cells that binds to oxygen. Without sufficient iron, the body can't produce enough healthy red blood cells, leading to iron-deficiency anemia, characterized by fatigue and weakness.

Calcium is vital for maintaining strong bones and teeth. A deficiency in calcium can lead to osteoporosis, a condition where bones become brittle and fragile from loss of tissue, typically as a result of hormonal changes, or deficiency of calcium or vitamin D.

The glycemic index measures the blood sugar impact of foods. It ranks foods based on how much they raise blood glucose levels compared to a reference food. Foods high on the glycemic index, such as white bread, cause rapid spikes in blood sugar, while low glycemic index foods, like whole grains, result in a slower increase in blood sugar. This is valuable for managing diets, especially for people with diabetes.

Vitamin K is necessary for blood clotting. It plays a key role in the activation of proteins and calcium essential in blood clotting. Without sufficient Vitamin K, the body cannot produce prothrombin, a critical blood-clotting factor, which could lead to bleeding problems and poor wound healing.

Vitamin A is essential for vision and skin health because it plays a crucial role in the formation and maintenance of healthy skin, teeth, skeletal and soft tissue, and mucus membranes. It is also vital for photoreception as it produces the pigments in the retina of the eye. Deficiency in Vitamin A can lead to impaired vision, particularly in reduced light (night blindness), and can cause skin issues.

Salmon is an excellent source of Omega-3 fatty acids, essential fats the body can’t make on its own. Omega-3s are crucial for brain function as well as normal growth and development. They have been shown to reduce inflammation and are important for cardiovascular health. Salmon contains more Omega-3s by weight compared to other foods typically high in Omega-3s like flaxseeds or walnuts.

There are approximately 9 calories in one gram of fat, making it the most calorie-dense macronutrient. This is important for dietary considerations where caloric intake needs to be monitored or adjusted. Fats are essential in the diet for the absorption of vitamins and providing energy, but due to their high caloric content, managing fat intake is crucial for maintaining a balanced diet.

Limiting alcohol consumption is recommended to reduce hypertension, or high blood pressure. Alcohol can raise blood pressure to unhealthy levels and reducing its intake can have a significant beneficial effect on blood pressure. Moreover, alcohol reduction can also help manage calorie intake and reduce the risk of cardiac problems associated with high blood pressure.
