Mycoprotein vs Soy: Which is better for you?

If you want a quick answer: mycoprotein is better for digestion, weight management and sustainability, while soy wins for muscle-building and protein density.
The best choice depends on your goals! Bur for busy UK workers wanting healthier, high-protein meals without fuss, mycoprotein is often the more convenient everyday option.

Mycoprotein vs Soy: Quick Comparison

• Mycoprotein: higher fibre, more filling, lower calorie
• Soy: higher protein, more versatile, good for muscle gain

Both are great plant-based protein sources, but they work differently in your body.

What Makes Mycoprotein Different?

Mycoprotein is a fermented fungi-based protein, naturally fibrous and full of gut-friendly beta-glucans.

Key advantages:

• High fibre = better digestion
• Low fat and low calorie
• More filling than chicken or soy
• Super sustainable

Most people don’t realise how much the fibre matters. It slows digestion, keeps you full and helps stop the classic 3pm desk-hunger crash.

What Makes Soy Different?

Soy is a high-protein legume and one of the world’s most studied plant-based protein sources.

Key advantages:

• Very high protein per serving
• Complete amino acid profile
• Great for muscle repair
• Extremely versatile

This makes soy a favourite in the gym world and great for anyone tracking macros.

Which Is Better for Weight Loss?

Mycoprotein wins.
Why? Because it ticks the three boxes that matter:

• Low calorie
• High fibre
• High satiety

The fibre in mycoprotein keeps you full for longer, making it perfect for people trying to cut back on snacking at work.

Which Is Better for Digestion?

Mycoprotein is usually easier on the stomach.
Its combination of chitin and beta-glucans supports gut health and moves through the digestive system more gently.

Soy can be tough for people with:

• IBS
• soy intolerance
• bloating or gas

If you’ve ever felt bloated after tofu or edamame, mycoprotein may suit you better.

Sustainability: A Clear Winner

Mycoprotein is one of the most environmentally friendly proteins on the planet.

Compared to soy, it uses:

• 90% less land
• 95% less water
• much lower emissions

Soy is sustainable compared with meat, but large-scale soy farming still impacts land use.

Mycoprotein is grown in fermentation tanks, no soil, no sunlight, no fields needed.

Both mycoprotein and soy are great protein sources, but they suit different goals.
Mycoprotein is ideal for everyday healthy meals, digestion and sustainability.
Soy is ideal for muscle building and hitting higher protein targets.
