Sprouts as a Primal Food: How They (May or May Not) Fit into an Ancestral Lifestyle

Primal, ancestral, paleo, caveman: all trendy terms you see everywhere these days, but they all come down to living and eating according to old principles from a time without processed food. So what fits in, and what doesn't?

Sprouts, for example, are one of those food categories you either love or couldn't care less about. Some people sprinkle them enthusiastically over every salad; others walk right past them in the supermarket, as if they were meant only for yoga influencers and rabbits. But as soon as you start eating a little more in line with our evolutionary ancestors, the same question pops up sooner or later: do sprouts actually fit in? And as so often, the answer is just a little more complicated than a simple yes or no.

Did our distant ancestors eat sprouts?

At first glance, sprouts may not seem entirely at home in a diet that takes evolution as its starting point. After all, that kind of diet is mainly about food that stays close to its original form: meat, fish, eggs, vegetables, fruit, nuts, root vegetables and the occasional bit of honey.

Yet sprouts were eaten long before processed foods came along. Various ancient cultures used sprouted seeds because of their availability, nutritional value and shelf life. In China, for example, mung bean sprouts were used more than 3,000 years ago, both as food and in traditional medicine. In the Middle East and parts of Africa, too, people sprouted grains and legumes to make them easier to digest and to make better use of their nutrients. Sprouts were practical: they could be produced without farmland, grew quickly and were a nutritious addition in times of scarcity. In short, sprouts are part of a very old food history.

A middle position

In today's evolution-conscious diets, sprouts occupy a kind of middle position. They are seeds, but no longer in their protected, "defended" form. As soon as a seed starts to germinate, it turns into a young plant with a completely different nutritional profile: fewer inhibitors, more vitamins, different enzyme activity and better digestibility. That is why many sprouts – especially vegetable sprouts – fit remarkably well within an ancestral approach to eating, while others (such as legume sprouts) call for a bit more nuance. In short: sprouts are not classic primal food, but they can be a modern, ancestral-consistent addition – provided you know which types suit you.

What sprouts actually are (and why it matters)

A sprout is simply a seed waking up. The hard shell breaks open, the tiny embryo starts to grow, and it is exactly that young plant that we eat. This sprouting process is the key to the whole story, because as soon as a seed germinates, its chemistry changes completely:

• The seed converts some of its sugars into vitamin C.
• Anti-nutrients such as phytic acid (and, in the case of grains, lectins) start to decrease.
• Antioxidants and sulphur-containing compounds, on the other hand, increase.

So you are no longer eating the "defended" seed, full of substances meant to keep animals and fungi at bay, but a young, growing plant that is mainly pushing nutrients forward.

What do ancestral eaters get from sprouts?

Sprouts are an interesting addition for many conscious eaters. Because the vitamin C content increases and anti-nutrients decrease during sprouting, minerals such as magnesium, zinc and iron become more available. For people who eat plenty of vegetables, meat and nuts, sprouts offer an extra source of bioactive substances, such as the glucosinolates in broccoli and radish sprouts. Sprouts also contain enzymes of their own. The protein in sprouts is easier to digest than that in the unsprouted seed as well: stored seed proteins are broken down into free amino acids during sprouting, making essential amino acids more available.

All of this does depend on the type of sprout.

The absolute winners: vegetable sprouts

This is the safe zone. Broccoli, radish, rocket and sunflower sprouts are almost always an easy "yes". Broccoli sprouts in particular contain extremely high concentrations of certain sulphur compounds that you will hardly find in such abundance in the mature vegetable. They fit perfectly into a way of eating that goes back to the evolutionary basics: lots of plant power, everything fresh and alive. If you want to start somewhere, start here.

The confusion around grain sprouts

And then there is the category that always raises eyebrows: grain sprouts. "But grains aren't primal food, are they?" people say. True. But note: with sprouts you are not eating the grain, but the little plant growing out of it – and that difference is bigger than it seems. When a grain kernel germinates:

• Lectins, the seed's "defence weapons", drop quickly in the first few days.
• The gluten-like proteins (such as gliadin and glutenin) are mainly found in the starchy endosperm of the kernel, not in the shoot that grows out of it. The young sprout consists far more of fibre and young plant cells than of those notorious grain proteins.
• The sprout uses the nutrients in the kernel to build itself, so most of the "problem substances" stay behind in the part you don't eat.

Does this suddenly make grain sprouts a superfood? Unfortunately not. You mainly eat fibre and water with a small amount of vitamins. In terms of micronutrients they are lightweights compared with real vegetables. But they are far less problematic than the grain they come from.

The tricky category: legume sprouts

This is where you really need to pay attention. While grain sprouts quickly break down their defensive substances, legumes often cling stubbornly to saponins, the natural compounds that can irritate the gut lining or make it more permeable. Alfalfa is the best-known example: very popular, but also quite rich in saponins, simply because it is related to the bean.

So yes, legume sprouts are milder than unsoaked beans, but from a primal-diet point of view they remain in the grey area. For many people they are simply not ideal.

And then there's the hygiene story

Sprouts grow in warm, moist conditions – exactly the paradise where bacteria such as E. coli and salmonella also like to go on holiday. Ready-made tubs of bean and alfalfa sprouts from the supermarket are particularly notorious. Sprouting your own is usually safer: rinse daily, use clean jars and apply a bit of common sense. It can be that simple.

How to use sprouts best

The best way to think of sprouts is as a fresh, lively addition to your plate:

• in an omelette
• on a grilled piece of meat or fish
• in a salad
• over a bowl of vegetables
• on a sandwich (if you don't eat strictly primal)
• or simply as a crunchy finishing touch

And above all: eat them raw. That way you get the most out of those newly formed nutrients.

So: do sprouts fit a "primal" lifestyle?

In summary:

Highly recommended: vegetable sprouts (broccoli, radish, rocket, sunflower)

Usually fine, but not very exciting: grain sprouts (far fewer anti-nutrients, little gluten, but also little nutritional value)

Borderline case: legume sprouts (still contain saponins, problematic for some people)

Best option: sprout your own (fresher, safer, often tastier)

Bottom line: sprouts are not a simple "yes or no" category within the ancestral diet paradigm. But with a little knowledge you can use them with confidence. Vegetable sprouts are absolute winners, grain sprouts are surprisingly mild, and legume sprouts are the category where you really need to judge how your gut reacts. As far as I'm concerned, sprouts simply belong in your kitchen, especially if you love fresh, crunchy and nutritious food: exactly what original eating is all about.
