Nutrients In Eggs

Eggs are a nutrient goldmine!

One large egg has varying amounts of 13 essential vitamins and minerals, high-quality protein, all for 70 calories.

While egg whites contain some of the eggs’ high-quality protein, riboflavin and selenium, the majority of an egg’s nutrient package is found in the yolk. Nutrients such as:

  • Vitamin D, critical for bone health and immune function. Eggs are one of the only foods that naturally contain vitamin D.
  • Choline, essential for normal functioning of all cells, but particularly important during pregnancy to support healthy brain development of the fetus.
  • Lutein and zeaxanthin, antioxidants that are believed to reduce the risk of developing cataracts and slow the progression of age-related macular degeneration, a disease that develops with age.

Friday News Round-Up from Health Professionals

It’s always great to see HP’s in the news sharing interesting health information and advice on how people can improve their lifestyles. Here are a couple of articles that we spotted this week:

Vitamin D: Sun, Skin & Food

It’s that time of year when the summer “glow” begins to fade as fall is right around the corner.

egg-pizza

With the days getting shorter and many people establishing new, busy routines for the school year, time spent outside starts to dwindle, so it’s important to remind clients about vitamin D intake. As we’ve discussed in a previous post, Vitamin D promotes calcium absorption in the gut and maintains adequate serum calcium and phosphate concentrations to enable normal mineralization of bone. Without sufficient vitamin D, bones can become thin, brittle, or misshapen. Aside from supporting bone health, vitamin D has other roles in the body, including modulation of cell growth, neuromuscular and immune function, and reduction of inflammation.1

Sun exposure is the primary source of vitamin D for most people. It is produced endogenously when ultraviolet rays from sunlight strike the skin and trigger vitamin D synthesis. Whether getting this vitamin from sun exposure, food, or supplements, it is biologically inert and must undergo two hydroxylations in the body for activation. The first occurs in the liver and converts vitamin D to 25-hydroxyvitamin D, also known as calcidol. The second occurs primarily in the kidney and forms the physiologically active form of the vitamin, 1,25-dihydroxyvitamin D, also known as calcitriol.

During certain times of the year the angle of the sun may be insufficient to synthesize vitamin D and sun exposure is limited. This is especially true in the northern latitudes during winter months, like where we are here at ENC! Good news is that vitamin D can come from the foods that we eat. Eggs are one of the few foods that are a naturally good source of vitamin D, meaning that one egg provides at least 10 percent of the Daily Value (DV). Other sources of vitamin D include fatty fish, beef liver, and fortified dairy foods.2

This kid-friendly recipe for Scrambled Mini Pizzas provides a good source of Vitamin D and is perfect for a quick meal on the go, or a nutritious after-school snack.

Scrambled Mini Pizzas

Serves: 4

Prep Time: 10 minutes

Cook Time: 10 minutes

Ingredients:

2 tsp. vegetable oil 1-1/2 cups chopped green OR red bell peppers ½ cup chopped onion 1 tsp. dried Italian seasoning 4 EGGS ¼ cup milk ½ cup shredded part-skim mozzarella cheese (2oz.), Divided ½ cup pizza sauce 4 English muffins, split, toasted Directions:

Step 1: Heat oil in large nonstick skillet over medium-high heat until hot. Add bell peppers, onions and Italian seasoning; sauté until tender, 3 to 4 minutes Step 2: Beat eggs and milk in medium bowl until blended. Pour over vegetables in skillet; sprinkle with ¼ cup cheese. Reduce heat to medium. As eggs begin to set, gently pull the eggs across the pan with an inverted turner, forming large soft curds. Continue cooking-pulling, lifting and folding eggs- until thickened and no visible liquid egg remains. Do not stir constantly. Remove from heat Step 3: Spread 1 Tbsp. pizza sauce on each muffin half. Top with eggs, remaining cheese, dividing evenly.

Focus on Zinc

Zinc is an essential mineral that is found naturally in some foods and fortified in others. In the body, zinc is required for the functioning of more than 300 different enzymes and plays a pivotal role in a large number of biological processes such as cellular metabolism and immune function. Zinc also supports normal growth and development during pregnancy, childhood and adolescence and is required for proper functioning of the senses of taste and smell.1

With all the important roles zinc plays in the body, it is important for health professionals to be mindful of zinc intake, particularly among patients in at-risk populations or in those who eliminate certain foods from their diet such as vegetarians.   According to NHANES III most infants, children, and adults consume the recommended amounts of zinc. However, according to the same study, some evidence suggests that zinc intakes among older adults might be marginal. NHANES III found that 35-45% of adults aged 60 years or older had zinc intakes below the estimated average requirement of 6.8mg/day for elderly females and 9.4 mg/day for elderly males.2

Aside from older adults, vegetarians are also a group at risk for zinc deficiency. Meat is a high bioavailable source of zinc, while legumes and whole grains contain phytates that bind to zinc and inhibit its absorption. Since vegetarians avoid meat and typically eat proportionally more legumes and whole grains, it is important to analyze patients’ diets and possibly recommend ways in increase zinc.3 Eggs can be a good option for vegetarians who consume them. They are a source of high-quality protein and also contain 4% of the Daily Value of Zinc. While this Daily Value may be relatively low compared to other foods, by pairing eggs with other zinc containing foods, such as low-fat dairy the meal can provide both high-quality protein and zinc. We suggest scrambling 2 eggs with one ounce of Swiss cheese  and  pairing with a glass of low-fat milk to provide almost 24% DV of zinc!4

Focus on Potassium

eggsAs health professionals, it is important to get a full health history from clients in order to assess nutrition and health status. An area to be mindful of is activity level and occupation, particularly as it relates to climate. Clients who exercise or work outside during the summer need to pay attention to intakes of key minerals, such as potassium.

Along with chloride and sodium, potassium is one of the most important electrolytes in the body. Electrolytes are minerals in the blood, urine, and bodily fluids that contain an electric charge. All of the cells in the body use electrolytes to carry electrical impulses and communicate with other cells, which enables bodily functions. Potassium is essential for the body’s growth and maintenance. Nearly 70% of the potassium in the body is found in fluids like plasma, blood, and sweat, while the rest is stored in the bones.2 During a hot day of outside exercise or work, potassium can be lost through sweat. When potassium is deficient in the diet, or when the movement of potassium through the body is blocked, nervous and muscular systems can be compromised.3

Fresh fruits, especially citrus and melon, and vegetables like leafy greens and broccoli, are all important sources of potassium. By comparison, eggs provide a smaller amount of potassium than many produce foods, but one large egg contains 69 milligrams of the nutrient and when paired with produce and whole grains, can offer a potassium-rich meal.  The recipe below pairs eggs with spinach and cheese, which both contain potassium, and when served with a cup of citrus fruits, this meal is a potassium powerhouse.

The Incredible, Edible, and Affordable Egg

ital bake

Protein has been a real buzzword lately, and for good reason. Protein is made up of amino acids, the building blocks for muscle, blood, skin, hair, and nails. In total, there are 20 amino acids, which join together in different combinations to form unique proteins in the body. Some of these amino acids, nine to be exact, can’t be made by the body, so they are known as essential amino acids, as it is “essential” that we consume these nine amino acids through the foods we eat. A complete protein source is one that provides all of the essential amino acids; these are also called high-quality proteins.1 Animal-based foods such as meat, poultry, fish, eggs, and cheese are considered complete or high-quality protein sources. Of all the high-quality sources of protein, eggs are the most affordable at an average of just 15 cents apiece and they deliver 13 other vital nutrients, including vitamin D, choline, riboflavin and phosphorus.2,3

Eggs are a  nutritious choice for families on a budget.  But it’s also important to pair eggs with the company they deserve, such as colorful seasonal vegetables, whole grains and dairy for a nutritious, balanced meal.
