Health Benefits

Vitamin B6

Vitamin B6 is part of the B-complex vitamins and has many uses which are essential to developing a healthy brain and maintaining a healthy body.

Vitamin B6 also helps your body:

  • maintain a healthy nervous system;
  • produce red blood cells;
  • remove unwanted chemicals from your kidneys and liver;
  • metabolize amino acids;
  • metabolize fats and carbohydrates, turning them into energy.

100 grams of raw banana has 0.4 mg of vitamin B6, which is about 18% of the daily recommended intake.


Manganese is a trace mineral, meaning it is required in your body in a very limited amount. It functions in the body as a key enzyme activator for enzymes that mediate phosphate group transfer (phosphate dehydrogenases and phosphate transferases), especially those concerned with the citric acid cycle, including alkaline phosphatase, arginase, and hexokinase.

Manganese also protects your cells from physiological stress and helps your body break down nutrients from your diet.

Other benefits of manganese include:

  • repairs connective tissue and bone;
  • aids in the absorption of magnesium;
  • promotes normal nerve and brain function;
  • has anti-clotting properties;
  • encourages healthy neurotransmitter levels;
  • promotes normal development and growth in children;
  • supports the utilization of E, C, and B-complex vitamins.

Symptoms of a deficiency in manganese include:

  • glucose levels of blood become impaired;
  • abnormalities in the skeleton systems of the human;
  • impairment in the production of the glycoprotein;
  • the metabolism of fats and lips get disturbed;
  • there is an increased risk of cancer in case of extreme deficiency.

100 grams of raw banana has 0.3 mg of manganese, which is approximately 13% of the daily recommended intake.


Potassium is a mineral that is essential for heart health, particularly blood pressure control. This mineral is also important as it regulates the movement of waste products and nutrients in and out of cells and helps maintain normal fluid levels in the body.

Because it is an electrolyte, this mineral helps your muscles recover from a physical exercise session and allows you to work out more.

100 grams of raw banana has 358 mg of potassium, which is approximately 10 percent of the daily recommended intake.


Avocado, also known as alligator pears, is a fruit that grows from the avocado tree, formally known as Persea Americana. It is thought that avocado trees are native to South Central Mexico, most likely originating in the Tehuacan Valley.

This fruit is added to various dishes due to its rich texture and good flavor and is prized for its high nutrient value. There are dozens of varieties of avocados ranging in color and size.

Health Benefits

Vitamin C

Vitamin C is involved in protein metabolism and is required for the biosynthesis of certain neurotransmitters, L-carnitine, and collagen (an important component of the connective tissue, that plays a crucial role in wound healing).

Vitamin C is also a potent antioxidant, protecting the human body from the damage of free radicals (an atom, molecule, or ion which has an unpaired valence electron). Free radicals have an essential role in the aging process, therefore, getting plenty of vitamin C can protect health both now and over the years to come.

100 grams of raw avocado has 10mg of vitamin C, which is approximately 17 percent of the daily recommended intake.

Magnesium is considered an electrolyte, along with potassium, calcium, and sodium. It is also a cofactor for more than 600 enzyme systems that regulate various biochemical reactions.

This essential mineral is required for the synthesis of RNA, DNA, and the antioxidant glutathione and contributes to the structural development of bone. In addition, magnesium works to help regulate brain receptors responsible for memory function, according to researchers at MIT.

Signs of magnesium deficiency include:

  • coronary spasms;
  • abnormal heart rhythms;
  • personality changes;
  • seizures;
  • muscle contractions and cramps;
  • tingling;
  • loss of appetite;
  • numbness;
  • weakness;
  • fatigue;
  • vomiting;
  • nausea.

100 grams of raw avocado has 29mg of magnesium, which is about 7% of the daily recommended intake.

Dietary Fiber

Increasing the consumption of fiber-rich foods like avocados can substantially lower the risk of both coronary heart disease and cardiovascular disease, according to a study done by the University of Leeds in the United Kingdom.

Eating foods with natural fiber can also help maintain a healthy digestive tract, prevent constipation, and lower the risk of colon cancer.

Dietary fiber is also very important for digestion since it helps ensure the smooth passage of food through the intestinal tract.

100 grams of raw avocado has 6.7g of dietary fiber, which is about 27 percent of the daily recommended intake.
