Calories and Nutrition in Farm Fresh Eggs
Eggs are an incredibly nutritious food that have been a staple in diets around the world for centuries. The humble egg contains a powerhouse of vitamins, minerals and other nutrients that make it one of nature's superfoods. Farm fresh eggs in particular provide an especially good source of nutrition.
Calorie and Macronutrient Content
At first glance, eggs are low in calories but high in nutrients. One large farm fresh egg contains only about 78 calories, with 6 grams of protein, 5 grams of fat, and trace amounts of carbohydrates. The protein in eggs is complete, meaning it contains all 9 essential amino acids that our bodies cannot produce on their own.
Here is the calorie and macronutrient breakdown for one large farm fresh egg (50 grams):
- Calories: 78
- Protein: 6g
- Fat: 5g
- Carbohydrates: 0.6g
The small amount of carbohydrates in an egg come from the trace amounts of sugar and fiber. Eggs provide a substantial amount of protein and fat, both of which promote feelings of fullness and help sustain energy levels.
Micronutrients
Eggs are packed with a variety of vitamins and minerals despite being relatively low in calories. Here are some of the micronutrients found in one farm fresh egg:
- Vitamin A: 6% of the RDI
- Folate: 5% of the RDI
- Vitamin B2: 15% of the RDI
- Vitamin B12: 9% of the RDI
- Vitamin B5: 7% of the RDI
- Selenium: 22% of the RDI
- Phosphorus: 9% of the RDI
Eggs contain small amounts of almost every vitamin and mineral needed in the human diet. Many of the vitamins and minerals in eggs are found in the yolk.
Other Nutrients
In addition to vitamins and minerals, eggs contain a variety of other healthy compounds:
- Choline: Eggs are one of the richest dietary sources of choline, an essential nutrient important for brain and liver health. One egg provides 147 mg of choline, well over 25% of the recommended daily amount.
- Lutein and Zeaxanthin: These antioxidants help prevent eye diseases like cataracts and macular degeneration. Most of the lutein and zeaxanthin is found in the yolk.
- Omega-3 Fatty Acids: Eggs from hens fed omega-3 enriched feed contain higher amounts of omega-3s EPA and DHA, which are linked to reduced heart disease risk.
Differences Between Farm Fresh, Organic and Conventional Eggs
Not all eggs are created equal. Farm fresh, organic and conventional eggs each have their own pros and cons in terms of nutrition, taste and ethics. Here is how they compare.
Farm Fresh Eggs
Farm fresh eggs come from small regional farms where hens are free to roam and access the outdoors. Farm fresh eggs differ from conventional eggs in a few key ways:
- Often more nutritious with higher vitamin A, E and omega-3 levels.
- Have brighter, firmer yolks.
- Tend to have thicker shells and lower risk of breakage.
- Come from hens raised in more humane environments.
The free-range nature of farm fresh eggs causes natural differences in nutrition compared to conventional eggs where hens are caged. However, there can be variability between different farm fresh eggs based on hen diet and lifestyle.
Organic Eggs
Organic eggs must come from hens fed an organic, all-vegetarian diet free of antibiotics and pesticides. Here are some attributes of organic eggs:
- Hens have access to the outdoors.
- No synthetic pesticides are used.
- Feed is organic and GMO-free.
- No antibiotics or hormones are given.
- May be more expensive than conventional eggs.
While organic eggs have their benefits, some studies show minimal nutritional differences between conventional and organic eggs. Still, the principles of organic farming may be important for consumers.
Conventional Eggs
Conventional eggs come from large-scale farms with caged hens fed non-organic grains. Here are some common practices for conventional eggs:
- Hens are kept indoors in small cages.
- Numerous hens confined in small spaces.
- Fed a grain-based diet.
- Lower cost than organic or farm fresh.
- Raised on antibiotics and pesticides.
While conventional eggs are generally nutritionally similar to organic and farm fresh, the living conditions of caged hens and industrial practices raise ethical concerns for many consumers.
How Hen Diet Affects Egg Nutrition
The diet and lifestyle of a hen changes the nutritional make-up of her eggs. Hens fed a natural, free-range diet produce eggs with different vitamins, minerals, fats and more compared to conventionally raised hens.
Vitamin E and Omega-3s
Pasture-raised hens that eat plenty of plants contain higher levels vitamin E and omega-3 fatty acids compared to conventional eggs. Both vitamin E and omega-3s are important antioxidants that help reduce inflammation and provide other health benefits.
Vitamin D
Hens raised outdoors in sunlight produce eggs with much higher vitamin D levels. Vitamin D aids calcium absorption and bone health, but deficiency is very common.
Vitamin A and Beta-Carotene
Natural greens and bugs eaten by pasture-raised hens boost carotenoids like beta-carotene in eggs. Beta-carotene is converted to active vitamin A in the body and provides antioxidant and immune benefits.
Fatty Acid Profile
The fats found in an egg depend directly on what the hen eats. Pastured hens produce eggs higher in omega-3s and healthy fats compared with grain-fed hens. The yolk's yellow color is also deeper with a better diet.
How Cooking Changes Egg Nutrition
Cooking alters the nutritional profile of eggs based on how much heat is used and for how long. Some vitamins are sensitive to heat while others remain stable.
Protein
Cooking has minimal effects on the protein in eggs. In fact, protein digestion may actually improve from heating. Both the whites and yolk provide an excellent source of complete protein.
Fats
High heat can oxidize and damage the fats in egg yolks. For maximal retention of healthy fats, use lower heat or cook just until the whites are set.
Vitamin A and B Vitamins
Some B vitamins and vitamin A are sensitive to heat. Using lower heat helps retain these heat-sensitive vitamins better than high-heat cooking methods.
Minerals
The main minerals in eggs such as selenium, iron and phosphorus are unaffected by heat. Boiling may decrease up to 10% of the iron content.
