Have You Seen Your Optometrist This Year?

A visit to the optometrist involves more than verifying if you need to wear glasses.  When you visit your optometrist, he or she also check your eye coordination and your ocular health.  The most likely eye diseases that any person living in the Western World will develop in their lifetime are:



Early diagnosis can prevent vision loss from all of these eye diseases.  So it's important to have your eyes checked by an optometrist regularly.

Dr. Barb's Top Five Ways to Prepare Eggs

Eggs are an important Eyefood because egg yolks contain lutein that is readily absorbed by the body.   Eggs are also high in vitamin E, and omega-3 eggs contain DHA - all important eye nutrients.

The Eyefoods Plan recommends eating 2 eggs twice per week.  Dr. Barb offers up some inspiration for you as she shares her top five ways to prepare eggs.

1.  Poached eggs served atop whole-grain toast and topped with roasted peppers

2.  Scrambled eggs prepared with baby spinach

3.  Herbed goat cheese omelette prepared with tarragon, parsley and low fat goat cheese

4.  Hard boiled eggs enjoyed as a quick snack with freshly ground black pepper

5.  Spinach and sundried tomato quiche

Butt Out to Prevent Vision Loss

Smoking Increases Your Risk for Blindness

Another reason to butt out.  Smoking is the number one modifiable risk factor for age-related macular degeneration (AMD).  So, smoking can cause blindness.  In fact, AMD is the leading cause of vision loss in the Western World and 8 million Americans either have AMD or are at high risk of developing AMD.


To put this into perspective.  There are 200,000 people currently living with lung cancer in the US (158,000 die of it each year). 

We all know that smoking causes lung cancer but not many people are aware that it can also cause AMD and vision loss.

Diabetes and Your Eyes

November is Diabetes Awareness Month.  Did you know that diabetic retinopathy is one of the top four causes of vision loss in North America.  The International Diabetes Federation estimates that 1 in 10 North Americans has diabetes and this number is on the rise.

World Diabetes Day is November 14, 2012 - one week from today.  This year, the campaign is Diabetes: Protect Our Future.  The goal is to educate, engage and empower youth on diabetes and diabetes prevention.  Nutrition and lifestyle are intricately linked to the development of Type 2 diabetes and the management of diabetes.

Let us work together to decrease the number of people with vision loss from diabetes.

Beta-Carotene


Beta-Carotene was included in the original Age-Related Eye Disease Study formulation. 

Since AREDS 1, scientific studies have shown that supplementation with beta-carotene can increase the risk of lung cancer in smokers. High levels of beta-carotene in the body can compete with lutein for transport to the tissues. As a result of these findings, AREDS 2 is investigating the effects of a supplement without beta-carotene.

Beta-carotene from food is safe and is important to maintain eye health. Sweet potatoes and carrots have an important place in an eye-friendly diet.

Zinc


Zinc is an essential mineral that has antioxidant properties. The Age-Related Eye Disease Study (AREDS) showed that supplementation with zinc decreased the risk of progression of AMD.

The recommended dietary allowance for zinc is 8 mg per day for women and 11 mg per day
for men.

High levels of zinc (80mg) in original AREDS formula has been showed to cause GI distress and urinary tract infections. AREDS 2 is studying the effects of decreasing the dose (25mg).

Include foods high in zinc in your diet to decrease your risk for AMD.  Foods high in zinc are oysters, lean beef, turkey breast, and nuts and seeds.

Omega-3 Fatty Acids - Part 2


Omega-6 to Omega-3 Balance

Eating cold-water fish on a regular basis (3-4 serving per week) increases the amount of omega-3 fatty acids in your diet.  However, you must watch the amount of omega-6 fatty acids (pro-inflammatory) you consume to reap the benefits of your fish intake.

The ideal ratio of omega-6 to omega-3 intake is 4:1 or less.  Yet, the typical omega- 6 to omega-3 ratio is 15:1 because omega-6 fatty acids are over- abundant in the standard North American diet.

Follow a diet that focuses on healthy fats (especially cold water fish) and avoids processed foods to help to improve their omega-6 to omega-3 ratio.

Omega 3 Fatty Acids - Part 1


Important Facts about Omega-3 Fatty Acids

Omega-3 fatty acids are unsaturated fatty acids that have anti-inflammatory properties and are part of the vision pathway to the brain.

ALA (alpha-linolenic acid) is an essential fatty acid that cannot be synthesized by the body and is found in flax, walnuts and chia seeds. The body converts ALA to the longer chain fatty acids, EPA (eicosapentaenoic acid) and DHA(docosahexaenoic acid).  The real benefits from omega 3s come from EPA and DHA. The conversion of ALA to EPA and DHA is not an efficient process in the body. 

Foods that contain EPA and DHA, especially cold-water fish, are the best food sources of omega-3 fatty acids.

Today is World Sight Day

The World Health Organization, Vision 20/20 and the International Agency for the prevention of Blindness recognize the  2nd Thursday of October as World Sight Day.  The purpose of this day is to increase the global awareness of blindness and sight threatening eye disease as major international health issues.

Vision 2020 is an initiative that works with government agencies, civil groups and professional organizations to eliminate avoidable blindness worldwide by 2020.  

285 million people are blind or visually impaired worldwide.

Have you had your eyes checked this year?

AREDS 2


AREDS 2 (Age-related Eye Disease Study )commenced in 2006 and we expect the results in 2013. Numerous other studies on nutrition and age-related macular degeneration have shown the benefit of lutein, zeaxanthin and omega-3s, and raised questions about beta-carotene and high zinc levels.  As a result, many optometrists and ophthalmologists are recommending eye supplements similar to that used for AREDS 2 even now.

If you have AMD and are taking an eye vitamin ask your optometrist or ophthalmologist which supplement is best for you.

These are the main differences from AREDS 1:
  The addition of 10mg lutein and 2mg zeaxanthin
   The addition of omega-3 fatty acids:  (650mg EPA, 350mg DHA)
   The elimination of beta-carotene
   The reduction of zinc from 80mg to 25mg

Three Retinal Pigments


Lutein, zeaxanthin, meso-zeaxanthin

Lutein, zeaxanthin and  meso-zeaxanthin are macular pigments that absorb blue light and protect the retina from oxidative damage while improving visual performance. Our bodies cannot synthesize lutein and zeaxanthin, but we can metabolize meso-zeaxanthin from lutein in the absence of zeaxanthin.
The average North American receives only 1 mg lutein per day from their diet.  Scientists believe that we need between 6mg and 10mg of lutein per day to maintain a healthy retina and prevent the progression of AMD.

Consume foods that are high in both lutein and zeaxanthin every day.

Foods high in lutein:  Leafy green vegetables, eggs
Foods high in zeaxanthin: Orange peppers, goji berries
Meso-zeaxanthin is not commonly found in food

Kale: The Lutein Powerhouse


One leaf of kale contains 10mg of lutein.  An excellent way to add kale to your daily diet is to make Dr. Barb’s Green Smoothie.

Ingredients
2 cups packed kale leaves, washed and coarsely chopped
2 ripe kiwis, peeled and quartered
1 cup sweet green grapes (or 1 banana)
Juice of one lime
1 cup filtered water
Directives
1.             Put grapes in blender. Twirl until blended.
2.             Add kiwis, kale and water. Blend until smooth.
3.             Check consistency and add water as needed.
4.             Taste; flavor will vary depending on how sweet the kiwis and grapes are.   Adjust accordingly.
5.             If too tart, omit the lime juice and add grapes.
6.             If sweet, add lime juice.
Tips: If kiwis are quite sweet, you will get more eye nutrients by using more kiwis and less grapes or bananas. If using bananas, adding lime juice is essential to reduce oxidation (browning) of the smoothie. Enjoy immediately and keep leftovers in individual reusable bottles in the fridge for up to four days. Before drinking leftovers, shake well.

Blue Light and The Eye


Blue light causes oxidative stress to the retina, especially in people with low macular pigment optical density (MPOD).  Blue light also causes visual disturbance.

Wear sunglasses that filter blue light for AMD prevention and enhanced visual performance.
