What the Yolk Color of Eggs Represent

-




Why do Egg Yolks Come in Many Different Colors?
    Egg yolks can range in color from pale yellow to deep orange. But why? There are many misconceptions that egg yolk color represents nutritional value or quality of the eggs, but this is a myth. The color indicates the diet of the hen. A light yellow yolk means the hen ate a wheat based diet. Yolks that are deeper orange color means that the hen ate a diet that was high in carotenoids. Carotenoids are a red pigment found in plants. Dark yolks are common in free range eggs, especially during the summer months. It comes down to the consumers preferred color. Many consumers want their eggs to be bright colored eggs, but it does not mean that the egg has more nutritional value than the other.

The Hens Diet

    There are certain foods that hens should avoid eating to avoid an off flavor in eggs. Garlic and onions are the two most common culprits that may impact egg flavor. A few other foods should be avoided because they contain toxin that can make hens ill or even may be fatal. Avocado pits and skins to hens should be avoided as they contain a toxin called persin. While persins are not toxic to humans they can be for certain animals such as hens. Hens feeds provide the nutrition necessary for hens to thrive, but there are other foods hens can have as well. Hens have fewer than 350 taste buds compared to humans 10,000. These foods include dark leafy greens which can have the eggs result in darker richer yolks. Lettuce kale, turnip greens and chard are also great options. Watermelon, strawberries, and blueberries make healthy snacks for hens in moderation. 

Nutrient Content in Eggs 

    There have been studies to conduct whether the hens diet will effect the nutrient content of eggs. Among the water soluble vitamins, vitamin B12 content of the egg can vary considerably, dependent upon its level in the hen diet. Folic acid supplementation and pantothenic acid levels in the egg also vary somewhat. 

Reflection

    Whether you like a bright egg yolk, or a dark orange yolk, that is dependent on your personal preference. Whatever color you prefer, will not determine the nutritional value of the egg. The nutritional value however, will be effected by the hens diet. Nutrient contents will be different based on the nutrients that the hen has eaten. Eggs are a great source of protein, and are used for a lot of different Easter dishes.

    Wow! I never knew why there was a difference in color and the reason for it in egg yolks. I eat eggs everyday and love the orange yolks. I always assumed it was because there was a higher nutrient content in the orange yolks in comparison to the yellow yolks.

The Sweet Benefits of Valentine's Day Chocolate

 With Valentine’s Day coming, we all love those sweet treats that come along with the holiday, whether chocolate, baked goods, or even fruit candies.  But have you ever wondered if chocolate could be healthy for you? Chocolate has three categories we may all know: dark chocolate, milk chocolate, and white chocolate. This is determined by the amount of cocoa solids made from cocoa beans mixed with cocoa butter and sugar. In America, a standard bar of dark chocolate has around 70% - 85% cocoa.  Dark chocolate contains a large amount of flavonoids which are antioxidants that protect our bodies from damage. So the higher the content of cocoa the higher the amount of flavonoids.  While dark chocolate has the benefit of flavonoids, there are more benefits including: A source of important minerals - such as iron, magnesium, zinc, copper, and phosphorus  Non-dairy - a good option for those with a milk allergy or sensitivity  High in fiber - around 4 grams per ounce...

Ketogenic Gets a Makeover

Ketogenic Gets a Makeover We have all heard of the ketogenic diet. The ketogenic diet focuses on the low-carbohydrate, high fat diet consumption. But what happens when an individual does not want to include high-animal fat sources in their ketogenic diet? Welcome, the ketotarian diet. The ketotarian diet is the plant-based version of the ketogenic diet, relying on plant-sources for fat. Plant sources, like nuts and olive oil, make up 60-75% of calories for fat. The premise of the ketotarian diet is similar to ketogenic diet, where you try to have your body enter a state of ketosis to the utilize fat for energy instead of your body’s main energy source of glucose, or sugar. Many benefits are claimed on this diet such as fat loss and disease prevention, however, this is still a very restrictive diet plan that has little research on it to support its efficacy. Basic guidelines presented by Dr. Will Cole, a functional medicine practitioner states: ...

Do you struggle with pre and post exercise nutrition?

What should i eat before and after a workout? First things first…carbohydrates, proteins and fats are important for the body before  and after exercise. Exercising muscle preferentially uses carbohydrates from stored glycogen, but fats are also an important fuel source for energy production during exercise. Fats and carbohydrates are the two major fuel sources during exercise. Fats must be translocated and broken down from their storage form before they are used. Typically there is enough carbohydrate stored as muscle glycogen for exercise but as muscle glycogen stores decline, the skeletal muscle will then use some amino acids (basic components of all protein). More specifically, the amino acid leucine is used for energy.              It is important to consume an adequate amount of carbohydrates exercise to delay fatigue and minimize gastrointestinal distress. It is also important to consume enough fluids to prev...
