Once called “star berries” by early Native Americans, blueberries have passed the test of time and are becoming increasingly popular in the current American diet.  Consumption of the little berry has more than doubled since 1995, and with good reason.  Let’s just say that whoever coined the phrase “Good things come in small packages” must have been a blueberry lover.

Our Backyard Superfruit

Who needs an imported, expensive acai berry when we have blueberries so close to home?  In fact, 38 out of the 50 states produce blueberries commercially, including Pennsylvania. This means they’re not only in your local grocery store, but they can also be popping up at local farmer’s markets! And there’s more good news – Fresh blueberries can be purchased year-round.

  • North American blueberries are available from April – October with peak season being mid-June to mid-August
  • South American blueberries are available from November – March

Choosing (and Keeping) the Best of the Best

When selecting your berries, pick plump, firm, dry blueberries with a dusty blue color (that powdered-appearance on the skin is natural.) And don’t be fooled – color, not size, is a sign of maturity. Blueberries should be deep purple-blue to blue-black. Berries that are red in color are not ripe and will be better if used for cooking rather than for eating raw.  Blueberries should be stored in the refrigerator and can be kept for up to 10 – 14 days (but with as good as they taste, they tend to get eaten long before they would go bad.)

Consider Freezing Your Own

Freezing your own berries is a great idea. You can save a lot of money by loading up on them when they are less expensive.  To freeze them properly:

  • Make sure the blueberries are dry before going into the freezer – either store without rinsing, or rinse and then dry them completely
    • If you choose to skip rinsing them prior to freezing, they must still be washed before eating
  • Place the dry berries in a re-sealable plastic bag, or other freezer container, and store them on a freezer shelf
  • For the best quality, use within 6 months

Big Benefits From a Small Berry

  • Nutritional information:
    • 80 Calories per cup
    • Good source of fiber (4 grams per cup)
    • Free of: fat, cholesterol, and sodium
    • High in: vitamin C and manganese
    • Blueberries contain polyphenols that have anti-inflammatory and antioxidant properties
      • These compounds may play a role in decreasing the inflammatory processes involved in various chronic health conditions including cardiovascular disease, cancer, and age-related cognitive decline

7 Simple Ways to Enjoy (the taste and health benefits of) Blueberries:

  • Top cereal, oatmeal, or yogurt with a handful of fresh blueberries
  • Make a fruit smoothie with fresh or frozen berries
    • Tip: Add a little lemon juice to your smoothie to help the berries keep their bright color.  They tend to take on a grey hue when mixed with too much dairy (due to it’s basic pH)
  • Add blueberries to pancakes or waffles
      • Tip: Gently fold the berries into the batter.  Stirring may cause them to break
  • Bake a batch of whole-wheat blueberry muffins
        • Tip: Coat the berries by gently tossing them in flour before adding them to the batter.  This will help to keep them from falling to the bottom while baking
  • Bake a blueberry parfait layered with plain or vanillaGreek yogurt and topped with low-fat granola
  • Add them to a sweet fruit salad or savory garden salad
        • Blueberries pair well with a wide range of flavors
  • The simplest (and sometimes best way) to enjoy blueberries – Eat them plain!


Ginger: More than Just a Spice

You have an upset stomach, so you’re told to sip Ginger Ale to help calm it.  But have you ever wondered why?  Although Ginger Ale is relatively new, the use of ginger to treat stomach upset and nausea is not.  Aside from treating nausea, ginger has other medicinal applications that have been practiced for over 2,000 years.

What has it been used for?

  • Upset stomach (including morning sickness and nausea/vomiting from cancer treatment and surgery)
  • Motion sickness
  • Colic
  • Gas
  • Diarrhea
  • Loss of appetite
  • Pain relief (arthritis, muscle soreness, menstrual pain)
  • Upper respiratory tract infections
  • Cough
  • Burns/skin pain (when used as a topical application)

So what exactly is ginger?  How can it potentially help with these conditions?  And is there any evidence behind its effectiveness in treating such ailments?

What is ginger?

The ginger we consume comes from the underground stem of the ginger plant.  This knotted, light brown stem produces the aromatic herb that is often described as pungent and spicy.  Aside from medicinal uses, ginger is widely used in cooking, where its distinct taste and aroma impart a unique flavor profile to many ethnic dishes.  Ginger can be purchased in various forms, including: fresh, dried, ground, crystallized, preserved, pickled, or as ginger oil.

How does it work?

The ginger root contains active components that are thought to reduce inflammation and nausea.  Some suggest that it also aids in blood circulation.

What does the research say?

  • Pregnancy-related nausea and vomiting
    • Some studies have shown that ginger may be an effective treatment for pregnancy-related nausea and vomiting.  An added benefit of using ginger in this application is the absence of adverse pregnancy-related outcomes (Note: always check with your health-care provider before beginning an herbal supplement, especially during pregnancy).

 

  • Menstrual pain
    • One study published in The Journal of Alternative and Complementary Medicine indicated that ginger taken during menstruation may reduce menstrual pain.  In this study, 250 mg of a specific ginger extract was given four times per day during the first three days of the menstrual period.  This regimen reduced pain as effectively as medications (mefenamic acid or ibuprofen) in 62% of women.

 

  • Muscle pain
    • In two double-blind, placebo-controlled, randomized studies, ginger resulted in moderate-to-large decreases in muscle pain experienced from exercise-induced muscle injury.

 

  • Osteoarthritis
    • Following the evaluation of a study consisting of 247 participants, highly purified and standardized ginger extract resulted in moderately decreased symptoms of osteoarthritis of the knee.

 

While none of these studies prove that ginger is always effective, they do shed light on its potential benefits.  Overall, there appears to be few negative side effects resulting from the use of ginger when compared to the use of other medications.  If you are experiencing any of the problems listed earlier, adding ginger to your diet may be helpful.  Even if it doesn’t relieve a particular ailment, incorporating ginger’s distinct flavor into your meals may prove to be a benefit in itself.

So here’s to ginger, good health, and good eats.

Note:  If you are contemplating taking ginger in the form of an herbal supplement, you should always check with your health-care provider first.
