The Health Benefits of Avocados

The Health Benefits of Avocados


The Avocado, also called an alligator pear, is a very popular food and I thought it would be worth taking a few minutes to discuss its health benefits.

Avocado’s are thought to have originated in southern Mexico, the world's largest producer of avocados.

They are a flowering plant from the avocado tree Persea americana, and the edible part is technically a large berry, making them a fruit. Some folks may consider them to be a vegetable. For most purposes, this distinction is not significant. There are different types species including west indian, guatemalan and mexican.

Around the world, avocados are grown in tropical climates near the equator and do not grow well in places where there is a frost or freeze.

The green pulp or flesh is the part that is consumed; the outer skin or peel as well as the inner seed are discarded.

Avocado can be prepared in a variety of ways including used as a spread on toast, as an ingredient to almost any food and perhaps most famously, as guacamole dip.

  • 12 grams of carbohydrates, 10 of which are dietary fiber
  • 2.9 grams of protein

Vitamin & Mineral Content

Because of their high fat content, they are rich in fat soluble vitamins not found in other fruits including B vitamins, Vitamins A, D and E.

The following vitamins and minerals are found in avocados:


  • Potassium (21%)

  • Vitamin B6 (20%)
  • Vitamin E [alpha tocopherol] (16%)
  • Niacin (13%)
  • Riboflavin (11%)
  • Thiamin (7%)
  • Vitamin A (4%)

Other Compounds

  • Fiber
  • Carotenoids (lutein, zeaxanthin)
  • Phytosterols (β-sitosterol)
  • Tocopherols
  • Squalene


Unlike many foods, researchers have actually looked at the health benefits of avocados!. Avocado consumption has been shown to

  • Improved cholesterol health
    • Reduce total cholesterol levels, triglycerides (by up to 20%), LDL cholesterol (up to 22%) and raising HDL, the good cholesterol (by up to 11%)
  • Half as likely to develop metabolic syndrome (prediabetes)
    • Lower body mass index
  • Lower Blood Pressure
  • Increase antioxidant absorption
  • May help with cancer
    • Inhibit side effects of chemotherapy
    • Inhibit growth of prostate cancer cells
  • Arthritis
  • Meal satiety, which could contribute to weight loss

The following health benefits can be stated about avocados. These recommendations are based on the nutritional content of avocados and not research specifically on avocados themselves.

  • Potassium intake (21%)
    • Important for normal muscle activity (heart, skeletal and smooth)
    • May lower risk of stroke, high blood pressure, kidney stones
  • Monounsaturated Fatty Acids
    • Cardiovascular: lower blood pressure, cholesterol, resting heart rate
    • Reduces coronary heart disease death, fatal heart attack, sudden cardiac death
    • Reduces stress, improves memory, decreases depression
  • Fiber
    • Normalize bowel movements, maintain gut health, lower cholesterol, improve blood sugar control and help maintain a healthy weight.
    • May also help with hypertension, inflammation and colorectal cancer
  • Carotenoids
    • Eye health, lower risk of cataracts, macular degeneration
  • Phytosterols
    • Helps with immunity, may help with cancer, HIV, infections
    • Weight loss
  • Vitamin K (39%)
    • Primary function in body is to stop bleeding via the coagulation cascade
    • Appears to help alzheimer's, coronary artery disease, osteoporosis and osteopenia, risk of fracture, hepatocellular carcinoma (liver cancer)
  • Folic Acid (Vitamin B9) (30%)
    • Role in nerve, brain function, DNA and RNA synthesis, red blood cells
    • Supplemented in pregnancy to prevent birth defects
    • May help with heart disease, alzheimer's dementia, depression and cancer


  • Avocados are an increasingly popular food worldwide
  • They are nutritionally dense, packed with healthy fats, vitamins and minerals
  • Research on avocado consumption shows lower cholesterol, blood pressure, risk of metabolic syndrome, arthritis pain and may help with cancer
  • Research on the nutritional components also shows:
    • high potassium content which helps with muscle function,
    • MUFA which lower risk of stroke, heart disease
    • Fibers which help with gut health, inflammation and healthy weight
    • Carotenoids which help with vision and phytosterols which are also healthy
  • Avocados may really be a superfood!
