Eggs and asparagus are two healthy and nutritious foods that can be great additions to a balanced diet. In this article, we’ll take a detailed look at the health benefits, nutrition facts, and any potential downsides of eating eggs and asparagus regularly.
The nutrition profile of eggs
Eggs are a powerhouse of nutrients. Here are some of the key nutrients found in eggs:
- Protein – One large egg contains about 6 grams of high quality protein. The protein in eggs contains all 9 essential amino acids required by the human body.
- Vitamin A – One large egg provides 10% of the RDI of this important vitamin. Vitamin A is essential for eye health.
- Riboflavin – Eggs are an excellent source of riboflavin which plays a key role in energy production.
- Vitamin B12 – One large egg provides about 15% of the RDI for B12, which supports red blood cell formation and neurological function.
- Selenium – Eggs contain decent amounts of the antioxidant mineral selenium which supports thyroid and immune system function.
- Choline – Eggs are among the richest sources of choline, which is important for brain development and health.
- Lutein & Zeaxanthin – These two antioxidants found in egg yolks help protect eye health and reduce the risk of eye diseases like cataracts and macular degeneration.
In addition to all these nutrients, eggs are also one of the few naturally occurring food sources of vitamin D. The vitamin D content depends on whether the chickens were fed vitamin D enriched feed.
Eggs also contain varying amounts of fat, cholesterol, sodium, calcium, zinc, and other vitamins and minerals.
Overall, the nutritional profile of eggs is quite impressive given their low calorie content. One large boiled egg contains only about 78 calories but packs in about 6 grams of protein along with all those nutrients.
Health benefits of eggs
Here are some of the main evidenced-based health benefits associated with egg consumption:
- High quality protein – The protein in eggs contains all the essential amino acids required by the body for growth and maintenance. The protein quality of eggs is so high that it’s used as the standard for measuring the protein quality of other foods.
- Muscle strength and mass – Several studies show that eating eggs enhances muscle strength and increases muscle mass, especially when combined with resistance training.
- Weight loss – Despite fears about cholesterol, eating whole eggs may promote weight loss. In one study, replacing a bagel breakfast with eggs resulted in 65% greater weight loss over 8 weeks.
- Brain health – The choline in eggs is important for optimal brain function and development. Adequate choline intake is associated with improved memory and mental performance.
- Eye health – Lutein and zeaxanthin in eggs help prevent eye diseases like cataracts and macular degeneration, the leading causes of blindness.
- Bone health – Eggs are a good source of vitamin D and calcium which support bone health. Observational studies link higher egg consumption with improved bone mineral density.
- Nutrient absorption – The high biotin content in eggs enhances absorption of other nutrients like B vitamins and trace minerals.
- Filling and satiating – Eggs are very filling due to their protein and fat content. This promotes satiety and reduces overall calorie intake.
The combined effects of all these benefits make eggs one of the healthiest foods you can eat. No wonder eggs have been described as nature’s perfect food.
Nutrition facts of asparagus
Here are some of the key nutrients found in asparagus:
- Folate – One cup of asparagus provides about two-thirds of the RDI for folate, a B vitamin essential for cell growth.
- Vitamin K – Asparagus is exceptionally high in vitamin K which plays a vital role in blood clotting.
- Vitamin A – This vegetable is high in antioxidant carotenoids like beta-carotene which the body converts into vitamin A.
- Vitamin C – One cup of asparagus provides about 20% of the RDI for vitamin C, an important antioxidant.
- Vitamin E – Asparagus contains decent amounts of vitamin E, a fat soluble antioxidant.
- Glutathione – This antioxidant compound is found in high levels in asparagus and may help detoxify carcinogens.
- Rutin – Asparagus delivers over 20% of the RDI for rutin, an anti-inflammatory antioxidant.
- Selenium – This trace mineral supports thyroid hormone metabolism and protects against oxidative damage.
In addition, asparagus is a good source of B vitamins like thiamine, riboflavin, niacin and pantothenic acid. It also provides other antioxidants like lutein, zeaxanthin and flavonoids.
Asparagus is low in calories, with only about 20 calories per cup. It contains almost no fat or cholesterol. The calories come mainly from carbohydrate in the form of fiber and sugars.
The high fiber and water content of asparagus means it provides volume and satiety without a lot of calories.
Health benefits of asparagus
Here are some of the key health benefits associated with eating asparagus:
- Heart health – The folate in asparagus helps lower blood homocysteine levels, a risk factor for heart disease. The antioxidant and anti-inflammatory nutrients may also promote heart health.
- Blood pressure – The combination of minerals like potassium, calcium and magnesium in asparagus help stabilize blood pressure.
- Digestive health – The high fiber content supports digestive health and improves gut bacteria. Inulin fiber in asparagus acts as a prebiotic.
- Birth defects – Getting adequate folate from foods like asparagus is especially important for women before and during pregnancy to prevent neural tube defects.
- Diabetes – The fiber helps slow down nutrient absorption and regulate blood sugar levels. Asparagus extracts may also improve insulin secretion.
- Cancer – Antioxidants in asparagus like glutathione, rutin and selenium have anti-carcinogenic effects and may protect against certain cancers.
- Anti-aging – Vitamin E and vitamin A (as beta-carotene) are two powerful antioxidants that fight cellular aging by eliminating free radicals.
- Vision – Carotenoids like beta-carotene in asparagus accumulate in the retina of the eye and protect against age-related macular degeneration.
Asparagus delivers an impressive array of vitamins, minerals and antioxidants that provide these health benefits. It’s also low in calories and high in fiber, making it a nutrient dense food choice.
Are eggs healthy?
Based on their nutritional profile and health benefits, eggs can definitely be described as a healthy and nutritious food.
Here are some key reasons why eggs are good for you:
- Eggs provide high quality protein with a complete amino acid profile required for muscle growth and development.
- They contain a variety of vitamins and minerals including selenium, riboflavin, folate, and vitamins A, B12, D, E and K.
- The antioxidants lutein and zeaxanthin in eggs help prevent eye diseases.
- Choline in eggs is essential for optimal brain health and development.
- Eating eggs promotes weight loss, muscle strength and bone health.
- Eggs improve nutrient absorption of vitamins and minerals.
- They are versatile, economical, easy to cook and make you feel full.
However, some people avoid eggs due to concerns about dietary cholesterol and impacts on heart health.
It’s true that eggs are high in cholesterol – one large egg contains around 185 mg of cholesterol which is over 60% of the recommended daily limit of 300 mg/day.
But research shows that dietary cholesterol has a relatively small effect on blood cholesterol levels in most individuals. Saturated and trans fats tend to drive blood cholesterol levels much more.
Population studies show that eating up to one egg per day is not associated with increased risk of heart disease in healthy adults. But people with certain medical conditions like diabetes may need to moderate egg consumption to less than 3 eggs per week.
Overall, eggs can be part of a healthy diet for most people when consumed in moderation. But those with high cholesterol or on cholesterol-lowering medication should consult with a doctor about their personalized limits.
