Muad’Dib: “Reach forth thy hand and eat what God has provided thee; and when thou are replenished, praise the Lord. ”
Fremen are mostly known as fierce warriors hitching giant sandworm rides, doing stabby things with giant sandworm teeth - but they’re also semi-nomadic people who had to figure out sustenance and nutrition on a desert planet.
With Frank Herbert’s focus on ecology planetology, he obviously took inspiration from the climate and people who occupy desert(-adjacent) areas here on Earth.

There’s dates and nuts and food packed in leaves. And there are also things where he just used Spice as a prefix: spice coffee, spicebread, and spice honey. (Surely not made by spice bees, though.)
And while the Dune Encyclopedia offers a whole article on Fremen cooking (and I’ll get to that in the end), for this piece, I wanted to stick to the core canon.
I wanted to see Herbert’s thinking on how to feed millions of people on what’s ostensibly a barren world. Are we hunting for desert creatures or are we breeding them? Is half the sietch a hydroponics bay? How do you get your calories?
We know there are food processing areas in a sietch.
[Harah] gestured at a tunnel branching to their left. “Through there and beyond, that’s food processing and stillsuit maintenance.”
But there’s less talk about how the ingredients get there in the first place. Especially en masse.
One thing worth remembering, though: the Fremen had so much Spice they could bribe the Spacing Guild into pretending their planet was empty.
So much, in fact, that the Guild wouldn't even look at bribes from Great Houses.
Halleck said: “Wouldn’t it be cheaper to reopen negotiations with the Guild for permission to orbit a frigate as a weather satellite?”
The Duke looked at Hawat. “Nothing new there, eh, Thufir?”
“We must pursue other avenues for now,” Hawat said. “The Guild agent wasn’t really negotiating with us. He was merely making it plain—one Mentat to another—that the price was out of our reach and would remain so no matter how long a reach we develop. Our task is to find out why before we approach him again.”
With that kind of wealth, one would assume that they could import what they were missing.
Now, this is only my headcanon, as Herbert is frustratingly quiet on the topic. Even when talking about meals, he kept it vague with “spice-laced foods” and “spice-laden diets” and rarely mentioned actual foodstuffs.
But what he did mention is in this article.
So grab your spice coffee and let's look at what kept the Fremen fueled.
Morsels
The first time we encounter Fremen food is when Chani hands Paul what might be the local version of an energy bar:
"Find a place to rest and stay out of the way, child-man," Chani said. "Here's food." She pressed two leaf-wrapped morsels into his hand. They reeked of spice.
[...]
Paul stood beside Chani in the shadows of the inner cave. He could still taste the morsel she had fed him—bird flesh and grain bound with spice honey and encased in a leaf. In tasting it he had realized he never before had eaten such a concentration of spice essence and there had been a moment of fear. He knew what this essence could do to him—the spice change that pushed his mind into prescient awareness."
This leaf-wrapped snack tells us a lot: they have bird meat somehow; they grow grain somewhere (probably hidden gardens in the sietches); and whatever it might actually be, they use spice honey as a binding agent. And they wrap it all in leaves, showing they don't waste a single bit of plant material.
And while it might be the normal amount for Fremen, Paul is taken aback by the amount of Spice in it. No surprise, either. Imagine if your trail mix came with a side effect of "might make you see the future."

Spice coffee in Dune: Part Two (2024)
I’m relieved to know that coffee remains a serious business across the known universe. But of course, on Arrakis, coffee isn't just coffee – it comes with an extra dose of stimulant in the form of Spice.
Spice coffee is everywhere in Fremen society. It's what you offer guests, what you drink to start your day, and apparently important enough that when you kill a guy in ritual combat, you inherit his coffee maker.
"The marker for Jamis' coffee service," Stilgar said, and he lifted a flat disc of green metal. "That it shall be given to Usul in suitable ceremony when we return to the sietch."

Steam wafted from the pot as she lifted the lid by its Hagar emerald knob. He could tell the coffee wasn't yet ready by the way she replaced the lid. The pot -- fluting silver female shape, pregnant -- had come to him as a ghanima, a spoil of battle won when he'd slain the former owner in single combat.
The coffee pot itself - described in Dune: Messiah as "a fluting silver female shape, pregnant" - isn't just kitchenware; it's a symbol that you belong to the tribe. Paul getting Jamis's coffee service means more than any verbal oath that he's now a real Fremen.
Breakfast of Champions
And for those who need more than a coffee to get their day going, we get a glimpse of Fremen breakfast in the third book:
As was the Fremen custom, the Atreides twins arose an hour before dawn. They yawned and stretched in secret unison in their adjoining chambers, feeling the activity of the cave-warren around them. They could hear attendants in the antechamber preparing breakfast, a simple gruel with dates and nuts blended in liquid skimmed from partially fermented spice.
Yumm, partially fermented spice juice. While we're reaching for our coffee or orange juice, the Fremen are knocking back what's essentially hallucinogenic kombucha before the sun even rises. No wonder they can ride giant worms.

Having said that, the dates and nuts make sense for desert people. Dates store well and provide quick energy. Nuts deliver protein and fats to keep you going.
