Updated: 5 days ago


Are Eggs Unhealthy?

Eggs – the nutritional powerhouses that offer more than just a tasty breakfast. Recent high-quality evidence from randomised controlled trials (RCT) and meta-analyses sheds light on the multifaceted benefits of eggs that transcends its shell to deliver nourishment, flavour, and a host of health advantages.

Cracking The Code!

Beyond their place on the breakfast plate, eggs stand as nutritional powerhouses, offering a myriad of health benefits that often go overlooked. Let's crack the code on recent high-quality evidence, exploring the complexities of egg consumption, and uncovering the truth about their impact on blood sugar balance, type 2 diabetes, cardiovascular health, body composition, and sustainability.

Is it Time to Celebrate the Egg?

In this blog post we'll delve into the nutrient-packed profile of eggs, understanding the vitamins and minerals that make them a remarkable addition to your daily diet.

Nutritional Value of Eggs: A Closer Look

1. Protein-Packed Breakfast for Blood Sugar Balance:

Embrace the savoury goodness of protein-based breakfasts for improved blood sugar balance. Eggs, rich in high-quality protein, supply essential amino acids crucial for muscle repair, promoting satiety and reducing the likelihood of energy spikes throughout the day.

2. Eggs and Type 2 Diabetes:

Contrary to some misconceptions, the latest studies reveal a nuanced relationship between egg consumption and type 2 diabetes (T2D). While observational studies suggested positive associations, RCT data showed no adverse effects on T2D markers. The nutrient profile of eggs, including biotin and choline, may contribute to metabolic benefits.

3. Cholesterol and Cardiovascular Health:

In the maze of information about cholesterol and cardiovascular health. Recent findings indicate that eggs, despite their cholesterol content, are associated with a null effect or a modest reduction in cardiovascular disease (CVD) risk. The cholesterol in eggs doesn’t necessarily translate to increased blood cholesterol, making them a heart-healthy choice for most individuals.

4. Body Composition and Satiety:

Eggs have shown promise in increasing muscle protein synthesis, thanks to their complete amino acid profile, and reducing fat mass, supporting optimal body composition. The high protein content also enhances meal satisfaction, potentially reducing overall energy intake for weight loss.

5. Sustainability and Planetary Impact:

Eggs emerge as an environmentally conscious protein source, boasting the lowest planetary impact among animal proteins. Choosing free range eggs aligns with sustainability goals, contributing to a healthier planet.
