If you've ever wondered whether tofu is actually healthy, you're certainly not alone.
Tofu is one of the most debated foods in nutrition. Some people praise it as a fantastic source of plant-based protein, while others worry that soy could affect hormones or be "too processed." With so much conflicting information online, it's easy to feel confused.
The good news? The evidence tells a much clearer story.
For most people, tofu is a nutritious, versatile food that can absolutely form part of a healthy, balanced diet. It's rich in protein, naturally low in saturated fat and incredibly easy to include in everything from stir fries to curries and salads.
In this blog, we'll separate fact from fiction, answer some of the most common questions about tofu and finish with one of my favourite recipes – a delicious Sesame Ginger Tofu Stir Fry that's ready in just 20 minutes.
What Is Tofu?
Tofu is made by curdling soy milk before pressing it into blocks, much like the process used to make cheese from milk.
Although it's often thought of as a meat alternative, tofu has been enjoyed across Asia for centuries and is simply another whole food ingredient rather than a modern "health food."
Depending on how it's made, you can buy:
Silken tofu
Soft tofu
Firm tofu
Extra firm tofu
For stir fries, firm or extra firm tofu works best because it holds its shape while cooking and develops a lovely crispy exterior.
Is Tofu Actually Healthy?
In short...
Yes.
Tofu is packed with nutrients while remaining relatively low in calories.
A typical serving provides:
High-quality plant protein
Healthy unsaturated fats
Iron
Calcium (if calcium-set)
Magnesium
Phosphorus
It's also naturally cholesterol-free and contains very little saturated fat, making it a great option whether you're trying to improve your overall diet, increase your protein intake or simply eat more plant-based meals.
Is Tofu Processed?
One of the biggest myths surrounding tofu is that it's "highly processed."
The reality is a little different.
While tofu is technically processed because soybeans are turned into soy milk before being pressed into blocks, this is considered minimal processing rather than the kind of ultra-processed food often associated with poorer health.
Think of it like:
Oats becoming porridge
Milk becoming yoghurt
Chickpeas becoming hummus
These foods are processed, but they're still nutritious choices.
Rather than focusing on whether a food is processed at all, it's more helpful to look at its overall nutritional value—and tofu scores highly.
Does Tofu Affect Hormones?
This is probably the question I hear most often.
Soy contains natural compounds called isoflavones, which are often referred to as phytoestrogens.
Despite the name, they don't behave the same way as human oestrogen.
Large reviews of the available research have found no evidence that moderate soy intake disrupts hormone levels in healthy men or women. In fact, soy foods can be enjoyed safely as part of a balanced diet by the vast majority of people.
As with most foods, variety is key. There's no need to eat tofu every day, but equally there's no reason to avoid it if you enjoy it.
Is Tofu Good for Weight Loss?
Tofu can be a brilliant choice if you're trying to lose body fat.
Why?
Because it's:
High in protein
Filling
Relatively low in calories
Versatile enough to replace higher-fat meats in many recipes
Protein also helps increase feelings of fullness, making it easier to stay satisfied between meals.
Of course, no single food causes weight loss on its own. Creating a sustainable calorie deficit while eating a balanced diet is what matters most.
Is Tofu Good for Building Muscle?
Absolutely.
Muscle growth depends on three key things:
Progressive strength training
Eating enough protein
Consuming enough total calories
Tofu can contribute to all of these by providing a quality source of protein that supports muscle maintenance and growth when combined with regular resistance training.
Whether you eat meat or follow a plant-based diet, tofu can be an excellent addition to your meals.
