Some impressive health benefits of apples

Who hasn’t heard the old wives’ tale, “An apple a day keeps the doctor away”?   Although not true, eating apples has some health benefits.  Fall is apple season and how fun it is to visit an orchard to pick or to browse and choose some freshly picked apples.  Growing up we did not hear much about the health benefits of apples.  But more research has found apples not only provide some good nutrition but also fiber and those healthy antioxidants.  

What are some health benefits of apples? 

Cleveland Clinic has a great article on 7 Reasons Why Apples are Good for You. 

  1. Blood sugar control – yes, apples do contain the natural sugar, fructose.  But unlike sugary foods like donuts, eating an apple won’t spike your blood sugar.  Why?  Because the fiber in the apple slows down the absorption of fructose, and apples are lower in sugar than processed foods like donuts.  In fact, a study of over 38,000 women found, those who ate one or more apples a day, had a 28% reduced risk of developing type 2 diabetes.   
  2. Lowers cholesterol – The American Heart Association notes that cholesterol can build up in your arteries and increase your risk of a heart attack or stroke.  Apples provide not only fiber but also antioxidants.  Both helps lower your cholesterol levels.  The pectin fiber in apples acts like a sponge, absorbs cholesterol in your GI tract and flushes it out of your body. 
  3. Lowers blood pressure – An Australian study found the antioxidant called “flavonoids” in apples may help protect against heart disease by lowering blood pressure.  Researchers believe it is the antioxidants, especially in the apple peel, and the fiber in apples that helps lower blood pressure.
  4. Lessens Inflammation – Chronic inflammation in our bodies isn’t good as it can cause tissue damage and lead to disease.  Apples help fight inflammation because they contain anti-inflammatory substances, the fiber and the antioxidant called “quercetin”.  Inflammation in your body can be measured by C-reactive proteins in blood and eating apples helps lower this blood protein. 
  5. Better gut health- As noted in my blog post, Is Greek yogurt good for you? , eating yogurt adds healthy probiotics to your day.  Those probiotics thrive on fiber.  Apples provide the fiber, pectin, which helps those healthy microorganisms grow in your gut.  Interesting, that the antioxidant, quercetin, actually “stops those harmful microbes from growing in your gut”. 
  6. Lessens hunger pains.  Feeling hungry?  Reach for an apple.  Dietitian Amber Somber, RD, LD, notes, Because apples are high in water and fiber, they make a filling snack”.  Fiber in foods slows down your digestion so you feel fuller, longer.  And apples are low in calories so a good healthy snack choice. 
  7. Live longer?  One study actually found apple eaters live longer.  Why?  Researchers “found that higher apple intake was associated with lower risk for cancer mortality, and that higher total fruit intake was associated with lower risk of CVD [heart disease]” death.  And apparently it does not take a lot of apples.  Another study found that just one apple a day lowered risk of lung cancer.

A medium apple provides:

  •       Calories95
  •  Carbs:  25 grams
  •  Fiber: 4 grams
  •  Vitamin C:  8 milligrams
  •  Potassium:  214 milligrams
  •  Antioxidants:  apples provide a variety of antioxidants 

How to add some apples to your day.  Besides eating a fresh apple, here are some other ways to add some apples to your day:

  •       Baked whole – so easy to do in a microwave.  A great dessert that also adds some nutrition to your day.
  • Chopped in salads
  • Smoothies

Where is the fiber?

About half the fiber (4 grams) in an apple is in the skin.  Don’t like the skin?  You will still get 2 grams of fiber.  One of my relatives will only eat peeled apples.  Fine.  The important thing is to eat apples and enjoy this fruit. 

Enjoy different varieties of apples.

Growing up many of us ate the Red Delicious apple.  Now one of the most popular apples is the Honeycrisp from the University of Minnesota.  Believe it or not but it took researchers 30 years to develop this crisp and sweet apple.  Other popular apple varieties include the Gala, Red Delicious, Fuji and the Granny Smith apple.  On a recent visit to Minnesota, we learned about a new apple variety being developed called the “First Kiss.”   

Some good cooking apples include Gala, Cortland, Empire, Fuji, Golden Delicious, Granny Smith, Jona Gold, and Honeycrisp. 

Conclusion:  How can you add some apples to your day?  My husband loves to eat apples, especially Honey Crisp.  As noted, a daughter hates the peel but buys cut up apples without the peel.  I like to cut up some apple each morning and add it to my morning oatmeal.  Or, enjoy a baked apple.  Apple juice is not a good way to add apples to your day as you miss out on the fiber and health benefits of a raw apple.  Try the baked apple recipe below.  So easy to prepare in the microwave.  Some other healthy apple recipes can be found at:  Recipe adventure…

Caffeine –good or bad for your health?

 

Caffeine – who doesn’t enjoy a cup of coffee in the morning?  Whether a K-cup, Starbucks or Mr. Coffee, most people enjoy starting their day with a cup of coffee.  According to the FDA, about 80% of adults in the US have some caffeine every day.   How does all this caffeine affect our health?

What beverages and foods have caffeine?

Coffee and tea have caffeine as does chocolate.  Energy drinks such as Red Bull contain caffeine. 

How much caffeine is safe to drink?

FDA notes that for most people, caffeine can be part of a healthy diet.  “But too much caffeine may post a danger to your health.”  FDA says healthy adults can consume up to 400 mg of caffeine a day which equates to about 4-5 cups of coffee a day, or 10 cans of soda, or 2 “energy shot” drinks.  But this varies as some people are more sensitive to caffeine and some people metabolize it faster or slower.  Pregnant or breastfeeding women should consult with their health care provider about limiting caffeine consumption.  FDA doesn’t have a caffeine recommendation for children but the American Academy of Pediatrics “discourages the consumption of caffeine and other stimulants by children and adolescents.” 

Can too much caffeine have side effects? 

According to the Mayo Clinic , if you drink more than 4 cups of coffee a day, you may experience a number of side effects including:

  •           Headache
  • Insomnia
  • Nervousness
  • Irritability
  • Frequent urination
  • Fast heartbeat
  • Muscle tremors

For some, even less than 4 cups a day may trigger some of these side effects.  If you don’t usually drink caffeinated beverages, you may be more likely to experience these side effects.

Is drinking coffee healthy?

A lot of research has documented good health benefits of drinking beverages with caffeine.  Johns Hopkins notes that coffee contains antioxidants that “may reduce internal inflammation and protect against disease...”.  For women, coffee drinkers have a reduced chance of death from heart disease, kidney disease, stroke, and diabetes.  You may be surprised to learn that coffee drinkers are “less likely to get type 2 diabetes”.   Drinking 1-2 cups of coffee a day may reduce risk of heart failure.  Family history of colon cancer?  The American Cancer Society notes that coffee drinkers, whether caffeinated or decaffeinated, have a lower risk of colon cancer.  Cleveland Clinic says regular coffee drinkers have a lower risk of developing Parkinson’s disease and Alzheimer’s disease. 

It is believed it is the antioxidants in coffee, decaf or regular, that help prevent diseases like “type 2 diabetes, heart disease, and cancers”.  Or it is the minerals coffee provides like chromium or magnesium which help control our blood sugar levels? 


 

Is coffee dehydrating?

Most people believe drinking coffee dehydrates you.  But Cleveland Clinic notes:  “At modest levels of intake, coffee is a net positive in terms of hydration, meaning it still contributes to your fluid needs,” Peart says.   (For information on hydration, see What beverage is best for hydration?)

How much caffeine is in beverages?   The Mayo Clinic lists the caffeine content of coffee, soda and more.  The math department the University of Utah has an extensive chart of the caffeine content of popular drinks.   The charts below are adapted from these two websites.

Conclusion:  I will continue to enjoy my cup of coffee every morning.  Or if you prefer, decaf or tea, drink those beverages.  As noted, it may not be the caffeine in coffee or tea that has health benefits but the antioxidants or minerals.  Learn how your body reacts to caffeinated drinks and what your tolerance level is.  Perhaps one cup is all your body can tolerate.  Perhaps coffee or tea interferes with your sleep if you drink it too late in the day.  Adapt your intake to your response to these beverages.  But what you add to your coffee can affect how healthy it is.  Skip the fake creamers, cream, and sugar.  Instead add some real cow’s milk to your coffee to add some good nutrition.  (See:  Real Milk vs Fake Milk? ) Instead of sugar, Johns Hopkins suggests stirring in some cocoa, vanilla, or some cinnamon for a flavor boost.

What are the health benefits of peanut butter?

Growing up who didn’t’ enjoy a peanut butter and jelly sandwich?  So many kids are raised on PB&J.  And many adults love to enjoy peanut butter sandwiches.  A favorite sandwich of Elvis Presley was a peanut butter and banana sandwich.  Are there health benefits to including peanut butter in your day?  My sister sent me an interesting article, The Popular Sandwich Spread That Helps Prevent The Risk Of Stroke.  I have heard a lot of benefits of eating peanut butter but had not heard that PB may help prevent strokes.

Peanuts, peanut butter, and health:

As noted in the article, about every 40 seconds someone in the US suffers from a stroke.  Many factors affect stroke risk including obesity, smoking, high blood pressure, high cholesterol, but diet also plays a role.  Some foods increase one’s risk of stroke including “diets high in sodium, processed meats, and sugar-sweetened drinks”. 

Including peanut butter and peanuts in one’s diet can reduce one’s risk of stroke. A study in 2021, found that higher peanut consumption was associated with lower risk of strokes and cardiovascular (heart) disease in both men and women.  Another study in 2022 found that eating peanuts can lower triglyceride levels and improve overall blood lipid levels.  An article in 2019 found that the antioxidant compounds in peanuts may help explain a reduced risk of lung, stomach, throat, colon, and pancreatic cancer in addition to improve cognitive health, especially in older adults.

To lower one’s risk of stroke one can also focus on a Mediterranean Diet full of fruits, vegetables, whole grains, nuts, and olive oil.  (See: Best Diets for Health 2023 )     

What makes peanuts and peanut butter so healthy?

A handful of peanuts or 2 Tablespoons of peanut butter are loaded with good nutrition.  Registered dietitian, Maggi Michalczyk says, “Generally, all nuts are good sources of healthy monounsaturated fats, protein, fiber, and many different vitamins, minerals, and antioxidants.”

  •         Protein:  2 Tablespoons of peanut butter provides about 7 grams of protein.
  • Magnesium:  Many American diets are low in magnesium and peanut butter provides 57 mg per 2 Tablespoons. 
  • Zinc:  This mineral is needed for a healthy immune system and for synthesis of protein among many other functions.  Peanut butter supplies almost 8 % of your daily requirement.
  • Niacin:  Peanut butter is a good source of niacin needed for energy production, healthy digestion, and nerve function.
  • Vitamin B6:  A serving of peanut butter provides about 14% of your daily B6 requirements.  B6 helps keep our “nervous system and immune system healthy”. 
  • Biotin:  Peanut butter supplies biotin a B vitamin known for healthier hair. 

What about peanut butter and Type 2 diabetes?

Peanut butter made without added sugar is naturally low in carbs which helps prevent spikes in blood sugar.  But peanut butter is high in calories at about 100 calories per Tablespoon so limit the serving to 2 Tablespoons. 

Are all peanut butters healthy?

Most nutritionists would recommend peanut butter made only from peanuts and salt.  This would avoid the added sugar.  But many kids don’t like this kind of peanut butter because it doesn’t spread well and is often very dry.  Skippy, Jif, and other popular peanut butters have some added sugar but you are still getting the health benefits of peanut butter.  Making the PB&J sandwich with whole wheat bread or wheat bread made with some whole wheat adds even more nutrition.  

What to avoid:

Skip the already made PB&J such as “Uncrustables”.  One of my students noted these on her diet recall. I had not even heard of them as we always made our own PB&J sandwiches.  Uncrustables have a long list of ingredients including 8 grams of added sugar, added hydrogenated oils and preservatives.  Much healthier to make your own PB&J. 

Conclusion:  Whether you enjoy a handful of peanuts or make a PB&J sandwich to enjoy, adding peanuts or peanut butter to your day has a lot of health benefits.  I always told my nutrition students to eat a handful of nuts a day as Dr. Oz recommended.  And for those who like PB&J sandwiches, enjoy them, just take the time to make your own.  Try different brands of peanut butter to find one you like.  We used a no sugar added peanut butter for years.  Then our kids would not eat it so we switched to Jif or Skippy.  Now the kids are grown and we are back to the natural no sugar added peanut butter.
