Pick Your Protein: A Guide to Plant, Fungi, and Cell-Based Alternatives

Choosing an alternative protein depends on your goals. Are you focused on taste, budget, or environmental impact? This page compares the three main categories side by side. Use it to find the guides most relevant to you. Each category comes with its own trade-offs, and there’s no single right answer for everyone.

AT A GLANCE

Compare Protein Types at a Glance

The table below gives a quick snapshot of how each protein type compares across the factors that matter most.

Protein Type	Source	Environmental Impact	Taste and Texture	Best For
Plant-Based	Soy, peas, wheat	Low to moderate	Varies by brand	Budget and availability
Fungi-Based	Mycelium	Low	Firm, meaty texture	High fiber, minimal processing
Cell-Based	Animal cells	Under study, likely low at scale	Closest to conventional meat	Matching meat’s exact taste

Plant-Based Protein

What Is Plant-Based Protein?

Plant-based protein comes from crops instead of animals. Common products include burgers, sausages, and ground “meat” made from soy, peas, or wheat gluten.

Common Sources

Soy, pea, and wheat remain the most widely used bases. Each offers a different balance of protein content, texture, and cost.

Mycelium Protein fermentated to make ground beef alternative

Fungi-Based Protein

What Is Fungi-Based Protein?

Fungi-based protein is made from mycelium, the thread-like structure fungi use to grow. It’s fermented and shaped into meat-like products.

How Mycelium Protein Is Made

Mycelium is grown in controlled fermentation tanks. It’s then harvested and processed into products like fillets, cutlets, and ground alternatives.

Cell-Based Protein

What Is Cell-Based (Cultivated) Meat?

Cell-based meat is grown from real animal cells in a lab or production facility. No animal is raised or slaughtered to produce it.

How Cultivated Meat Is Produced

Cells are placed in a nutrient-rich environment and allowed to multiply. Over time, they form muscle and fat tissue similar to conventional meat.

Regulatory Status and Availability

Cultivated meat has cleared regulatory approval in a small number of countries. Availability remains limited but is expanding as production scales.

OUR METHODOLOGY

How We Evaluate Each Protein Type

To keep our comparisons fair and consistent, we score every protein type against the same four factors.

water use compared to conventional meat production

each option replicates the taste and texture of conventional meat

each category matched to the shopper it suits best

Source

We look at what the protein is actually made from, whether that’s a crop, a fungal culture, or cultivated animal cells.

Environmental Impact

We consider land use, water use, and emissions compared to conventional meat production, based on published research and industry data.

Taste and Texture

We evaluate how closely each option replicates the taste and texture of conventional meat, since this often decides whether people switch at all.

Best For

We match each category to the shopper it suits best, based on cost, availability, and how it’s typically used.

These four factors shape every guide and comparison on this site.

FAQ

Frequently Asked Questions

Is fungi-based protein safe to eat daily?

Yes. Fungi-based protein is generally recognized as safe and is high in fiber, making it suitable for regular consumption.

How does cultivated meat compare in price to plant-based meat?

Cultivated meat currently costs more due to limited production scale. Prices are expected to fall as the industry grows.

Which alternative protein has the most protein per serving?

This varies by brand and product. In general, plant-based and cell-based options offer comparable protein levels to conventional meat.

Is fungi-based protein suitable for vegans?

Yes. Fungi-based protein is plant-derived and typically free from animal products, though it’s worth checking individual product labels.

Can I find cultivated meat in grocery stores yet?

Availability is still limited and varies by country. Most cultivated meat is currently sold through select restaurants rather than retail stores.

Which alternative protein has the lowest environmental impact?

Fungi-based protein generally requires the least land and water to produce, though all three categories use fewer resources than conventional meat.

Is fungi-based protein suitable for vegans?

Yes. Fungi-based protein is plant-derived and typically free from animal products, though it’s worth checking individual product labels.
