Health Benefits

There are many health benefits of eating an apple a day.

    1. Weight Loss- several studies have demonstrated that eating whole apples, not cooked apples, with meals  confers more fullness and less calorie consumption. The high soluble fiber and water content contribute to that fullness.
    2. May Be Good for Heart- the soluble fiber helps lower cholesterol, and polyphenols (like quercetin) in the skin reduce blood pressure and LDL cholesterol oxidation. This helps reduce heart disease and stroke.
    3. Prebiotic Effect and Help Good Gut Bacteria-  contain pectin, a type of prebiotic
    4. Helps control blood sugar- the fiber help slow the digestive process absorption of sugar
    5. Boosts immune system- nutrients like vitamin C help boost the immune system and ward off infection.


Health Risks

As you can see there are many health benefits to eating apples. Raw apples, eaten close to when to they are picked confer the most benefit as their nutrient content are higher. There are, however, some potential risks. 

  1. Apple seeds contain cyanide, so avoiding them in large numbers is best.
  2. Conventionally grown apples contain on average 4 pesticides, used to reduce mold and worms. Many of these are deleterious to human health. Apples rank high on the Environmental Working groups Dirty Dozen. It is best to buy organic apples. 
  3. FODMAPS- Apples are part of a group of short chain carbohydrates that are resistant to digestion and can produce gas and bloating in sensitive individuals when certain gut bacteria use them for fuel. If you  have this sensitivity, it may not be permanent;  it may mean your gut bacteria are not in balance and you need to see someone to help you rebalance the ratio.

Bottom Line

Eating an ‘apple a day’ may very well help keep the doctor away. Whole, organic apples confer the best benefits. Cooking will destroy some of the heat sensitive nutrients but will still confer health benefits- especially if you leave the peels. So… start filling your cart with a variety of delicious apples today.
