The Health Effects of Nutritional Deficiency in The Human Body

Nutrition is an essential component of overall health and well-being. It is a science that studies how nutrients in food interact with the body, and how these interactions impact our health. Nutrients are vital for the normal growth of and maintenance of the body, and they provide the energy needed to perform daily activities. In this article, we will discuss the health effects of nutritional deficiency in the human body, most common nutrient deficiencies, mineral balance, the importance of proper nutrition, and the most nutritionally dense foods available on earth!

Part 1: The Effects of Nutrient Deficiencies

Nutritional deficiency occurs when the body does not get enough of the necessary nutrients from the food we eat. This serious nutrient deficiency can lead to a variety of health problems. Here are some of the most common health effects of nutritional deficiency:

Neural Tube Defects

Neural tube defects (NTDs) are a group of birth defects that occur when the neural tube, a structure that forms early in fetal development and eventually develops into the baby’s brain and spinal cord, fails to close properly. The most common NTDs are spina bifida, anencephaly, and encephalocele.

Spina bifida is a condition in which the spinal column does not close completely, resulting in damage to the spinal cord and nerves. Anencephaly is a severe defect in which the brain and skull do not form properly, and the baby is born without parts of the brain and skull. Encephalocele is a rare defect in which a portion of the brain protrudes through an opening in the skull.

NTDs can have serious consequences for a child’s health and development, including physical disabilities, intellectual and developmental delays, and in some cases, death. The causes of NTDs are not fully understood, but they are believed to be a combination of genetic and environmental factors.

Folic acid, a B vitamin, has been shown to reduce the risk of NTDs. Pregnant women are advised to take folic acid supplementation to help prevent NTDs. It seems a better idea might be grass fed beef organs and kelp being advised to become a regular part of the diet.

Cognitive Dysfunction

Micronutrient deficiencies can cause cognitive dysfunction, which can affect memory, concentration, and overall brain function. For example, a deficiency in vitamin B12 can cause memory loss and confusion.

Fatigue and Weak Immune System

Nutrient deficiency can cause fatigue, making it difficult to perform daily activities. Nutrient deficiency, in iodine, folate deficiency, vitamin D, and vitamin C deficiency can weaken the immune system, making the body more susceptible to infections and illnesses. Every cell in the body utilizes Vitamin C, so we need it in large amounts on a daily basis. With the constant turnover of the same soil on commercial farms, the amount of Vitamin C found in an orange 80 years ago compared to today is drastically less.


A lack of iron can lead to anemia, a condition in which the body does not have enough red blood cells to carry oxygen to the tissues. Seaweed is a superfood that in small amounts can offer the body the appropriate amounts of iron, Vitamin C, iodine and all the other nutrients and trace elements the body needs for optimal health.

Stunted Growth

Children who do not receive adequate nutrition may experience stunted growth and development. This can have long-term effects on their health and well-being.

Delayed Healing

Severe iodine deficiency, can slow down the thyroid. Other micronutrient deficiencies can slow down the healing process, making it difficult for the body to recover from injuries severe infections and illnesses. The use of seaweed to treat wounds dates back to Roman times. Derived from seaweed and other brown algae, alginates are still used today in wound dressings for skin grafts, burns, and other difficult wounds. and forms a gel that moistens the tissue to speed healing and reduce pain and trauma during dressing changes.

Poor Digestive Health

A lack insufficient intake of fiber and other nutrients in vegan diets can cause poor digestive health, leading to constipation, diarrhea, and other digestive problems. Seaweeds have a high proportion of soluble fiber, with an average content of 24.5 g/100 g and 21.8 g/100 g for insoluble fiber.

Skin Problems

Skin problems, such as dryness, acne, and eczema and all caused from deficiencies or imbalances that can be corrected. Signs of aging are signs the body is lacking what it needs to be optimally healthy. Working on your gut health = working on your skin health.

Mood Disorders

A lack of certain nutrients, such as omega-3 fatty and essential amino acids in, can lead to mood disorders, such as depression and anxiety.

Most Common Nutrient Deficiencies

Serious health consequences can be prevented by consuming a balanced diet that includes a variety of nutrient-rich foods. Grass-fed, grass-finished beef, bone broth, wild mushrooms, fish oil micro and whole fish oil macro algae, and shilajit are some of the most nutritionally dense foods available on earth. However, it is important to remember that there are many other important nutrients that the body needs to function properly.

Iron Deficiency

Iron is essential for the production of hemoglobin, which carries oxygen in the blood. Iron deficiency can lead to anemia, fatigue, and weakness.

Vitamin D Deficiency

Vitamin of vitamin D is important for bone health, cardiovascular disease, immune function, and overall health. Vitamin D deficiency can lead to weak bones, increased risk of chronic diseases, and weakened immune function.

Vitamin B12 Deficiency

Vitamin B12 is important for muscle and nerve function, DNA synthesis, and red blood cell production. Vitamin B12 deficiency can lead to anemia, fatigue, and nerve damage. Seaweeds are full of B Vitamins, in particular dried green and red seaweed contain substantial amounts of vitamin B12.

Calcium Deficiency

Calcium is essential for bone health, nerve function, and muscle function. Calcium deficiency can lead to weak bones, bone pain, muscle cramps, bone pain and an increased risk of osteoporosis. The most bioavailable form of calcium is found in algae. There is a company in Vancouver called AlgaeCal who has proven repeatedly that red algae offers the most bioavailable form of calcium.

Copper deficiency and signs of aging

Copper is an essential mineral that plays a vital role in many bodily functions. It is involved in the production of red blood cells, the of red blood cells, formation of collagen, and the absorption of iron. Copper is also an antioxidant that helps protect red blood cells from damage caused by free radicals.

One of the most significant public health effects of copper deficiency is its impact on signs of aging. Studies have shown that copper deficiency can lead to premature aging of the skin, including wrinkles, sagging, and age spots. This is because copper is involved in the production of collagen, which is essential for maintaining the elasticity and firmness of the skin.

Copper deficiency and brain aneurysm

Copper deficiency has also been linked to an increased risk of brain aneurysm. An aneurysm is a bulge in a blood vessel caused by a weakened or damaged artery wall. If an aneurysm ruptures, it can up blood pressure and cause a stroke, brain damage, or even death. Studies have shown that copper deficiency can weaken the walls of blood vessels, making them more susceptible to aneurysm formation.

Use this food guide to find a few ways to increase your copper intake. Balance and harmony are important, and shouldn’t be overlooked. For example, if you are supplementing zinc, many doctors recommend to supplement copper at the same time. Zinc reduces the amount of copper that the body absorbs, and high doses of zinc can cause copper deficiency.

Part 2: The Importance of Proper Nutrition

Proper nutrition is essential for good health. It provides the body with the necessary nutrients to maintain bodily functions and prevent disease. According to the World Health Organization (WHO), about 2 billion people worldwide suffer from nutrient deficiencies, including deficiencies in vitamin D, vitamin A, iron, iodine, and zinc. In North America, although malnutrition is less common than in other parts of the world, a significant number of people still suffer from nutrient deficiencies especially Vitamin D.

In the United States specifically, it is estimated that up to 40% of the population may have deficiencies in vitamin D, which is important for bone health and immune system function. However, the exact percentage of the population with deficiencies can vary depending on the specific nutrient in question and other factors such as age, gender, and diet.

Some groups, such as pregnant women, children, and the elderly, may be at higher risk for common nutrient deficiencies. Kelp is the only rich source of vitamin D from a vegetable source.

Here are some of the benefits of proper nutrition:
