The Nutrient-Dense Upgrade: What to Eat More of After You Quit Seed Oils

Most clean eating content is written in the negative. Avoid this oil. Read labels for that ingredient. Don't trust anything that comes in a crinkly bag. This is useful — but it only gets you halfway there.

The elimination phase matters. Removing seed oils from your diet is a genuinely meaningful change that reduces your intake of oxidized polyunsaturated fats and brings your omega-6 to omega-3 ratio closer to something your body was built to handle. People feel different after doing it, and not in a placebo way.

But here is what often happens: someone quits seed oils, feels better for a few weeks, then plateaus. Energy is better but not great. Inflammation is down but joints still ache sometimes. Sleep improved but skin is still off. They've done the elimination work — and hit a ceiling.

The ceiling is usually not a seed oil problem anymore. It is a nutrient density problem.

This article is about the optimization phase: the foods worth eating more of after you've cleaned up the fat quality in your diet. Not supplements (mostly). Not exotic ingredients. Real foods that happen to be exceptionally rich in the nutrients modern diets consistently run low on.

The Elimination-Optimization Gap

When you cut seed oils, you remove one of the primary sources of excess linoleic acid (an omega-6 fat) from your diet. That is good. But removing something is not the same as replacing it with something better.

Many people who transition away from seed oils end up replacing them with:

More olive oil and avocado oil (good fats, lower omega-6, but not nutrient-dense in any meaningful way)
More nuts and nut butters (still high in omega-6 depending on variety)
Coconut oil (excellent for cooking, but nearly devoid of micronutrients)
Grass-fed butter and ghee (better, and richer in fat-soluble vitamins, but not enough on their own)

The fat quality improves significantly. But if the rest of the diet stays the same — lean proteins, vegetables, and the occasional grain — you may still be missing a substantial amount of what your body needs to function optimally.

The foods discussed below are not obscure. They are the foods that traditional and ancestral diets built around because they work. Modern industrial food systems phased most of them out in favor of cheaper, more convenient, more shelf-stable alternatives. Unsurprisingly, the alternatives are often the same seed oils you just cut.

Grass-Fed Red Meat: The Nutrient Baseline

The difference between conventionally raised and grass-fed, grass-finished beef is not marketing. It is measurable in the nutrient composition of the fat.

Grass-fed beef contains meaningfully higher concentrations of:

Conjugated linoleic acid (CLA) — a naturally occurring trans fat with a different structure and different physiological effects than industrial trans fats
Omega-3 fatty acids — not at the same level as salmon, but present, and significantly higher than grain-finished beef
Vitamin K2 (MK-4) — a fat-soluble vitamin almost entirely absent from grain-finished beef, associated with cardiovascular and bone health
Fat-soluble vitamins A, D, and E — all more concentrated in the fat of pastured animals

The key word is "grass-finished." Many beef products labeled "grass-fed" were started on grass and finished on grain. Check for "grass-finished" or "100% grass-fed and finished" to know the animal ate grass its entire life.

Practical applications: prioritize grass-fed ground beef over lean chicken breast as your default protein. Add grass-fed beef sticks to your rotation for portable protein that keeps you out of the gas station snack aisle. Cook with the fat, not just the muscle.

Paleovalley Grass-Fed Beef Sticks — Real protein, no seed oils, nothing to explain

Naturally fermented, 100% grass-fed and finished, zero canola or soybean oil. Seven grams of real protein per stick with a short ingredient list you can read in three seconds. If you carry snacks, these should be in your bag.

Organ Meats: The Most Nutrient-Dense Foods on Earth

This section will make some people uncomfortable. Keep reading anyway.

Liver — specifically beef liver from pastured animals — is the single most micronutrient-dense food available. It contains extremely high concentrations of:

Vitamin A (retinol) — the preformed version that your body uses directly, unlike beta-carotene from vegetables which must be converted (and conversion efficiency varies significantly between people)
B vitamins across the board — including B12, folate, riboflavin, and B6 at concentrations that make supplements redundant
Heme iron — the most bioavailable form of iron, far better absorbed than the non-heme iron in plant foods
Copper — a trace mineral chronically low in modern diets, important for immune function and connective tissue synthesis
Coenzyme Q10 — present in heart muscle in particular

The reason most people don't eat organ meats is not that they are unhealthy. It is that industrial food culture stopped normalizing them sometime in the mid-20th century. Virtually every traditional food culture ate organ meats regularly — not because they were desperate, but because they are the most nutritious parts of the animal.

You do not need to eat liver every day. Two to four ounces once or twice a week covers a meaningful amount of your fat-soluble vitamin and B vitamin needs. Beef liver cooked with butter, onions, and salt tastes nothing like the overcooked, gray liver served in bad institutional cooking. Done well, it is genuinely good food.

If the taste is a dealbreaker, desiccated liver capsules from grass-fed animals are the next best option — not as good as the real thing, but a reasonable supplement-based approach.

Collagen-Rich Foods: What Modern Protein Sources Miss

Muscle meat — chicken breast, lean beef, protein bars — is high in the amino acids methionine and cysteine. It is low in glycine and proline. This imbalance matters because glycine is the dominant amino acid in collagen, and collagen is what your joints, tendons, skin, and gut lining are made of.

Traditional diets corrected this naturally because people ate the whole animal: bone broth from long-cooked bones, slow-cooked cuts full of connective tissue, skin and cartilage. Modern high-protein diets built around boneless skinless chicken breast and whey protein isolate skew heavily toward methionine-dominant proteins, with very little glycine.

Practical ways to add collagen-rich foods:

Bone broth — homemade or from quality sources. Sip it, cook with it, add it to soups. Real bone broth contains gelatin and glycine that commercial "broth" (basically flavored water) does not.
Slow-cooked cuts — short ribs, oxtail, chuck roast, lamb shoulder. These have significant connective tissue that breaks down into gelatin during long cooking. They're also cheaper than premium cuts.
Chicken with skin and bones — roasted whole chicken or bone-in thighs. The skin and cartilage around the joint are collagen sources.
Skin-on fish — the skin contains collagen. Most people throw it away.

If you are eating primarily boneless, skinless muscle meat, you are likely running a chronic glycine deficit even if your total protein intake looks fine on paper.

Wild-Caught Fish: The Omega-3 That Moves the Needle

The omega-6 to omega-3 ratio in most modern diets runs somewhere between 15:1 and 20:1. Researchers estimate that traditional diets ran closer to 4:1 or even 1:1. The elevated ratio is largely a function of seed oil consumption — removing seed oils is the fastest way to bring it down.

But you also need to bring omega-3s up.

Wild-caught fatty fish — salmon, sardines, mackerel, herring, and anchovies — are the most efficient sources of EPA and DHA, the omega-3 fatty acids that reduce systemic inflammation and support cardiovascular and neurological function. Farmed salmon is lower in omega-3s and higher in omega-6s than wild-caught, and often fed grain-based pellets rather than their natural diet.

Aim for two to three servings of fatty fish per week. Sardines in olive oil or water are one of the cheapest and most nutrient-dense foods available: omega-3s, calcium (from the bones), selenium, B12, and vitamin D in one small tin. They take some getting used to if you weren't raised eating them. They're worth the adjustment.

Pastured Eggs: A Clean Protein That Does More Work

Not all eggs are equal in nutrient composition. Eggs from pasture-raised hens — hens that have access to outdoor space and forage on insects and grass — have higher concentrations of fat-soluble vitamins A, D, and E, and better omega-3 content compared to eggs from grain-fed confined hens.

The yolk is where the nutrition is. An egg white-only diet or a diet heavy in liquid egg products is optimized for protein content at the expense of the fat-soluble vitamins and choline in the yolk.

Choline is particularly worth highlighting. It is essential for liver function, cell membrane integrity, and neurotransmitter synthesis. It is chronically underconsumed in modern diets. Eggs are one of the best dietary sources. Two eggs per day provides most adults with a meaningful share of their daily choline needs.

Practical guidance: buy pastured or "pasture-raised" eggs, not just "cage-free" or "free-range" (these terms have weaker standards and less outdoor access). The yolks will be noticeably more orange. Cook them in butter or tallow. Eat the whole egg.

Fermented Foods: The Gut Layer Clean Eating Often Misses

Eliminating seed oils and processed foods is one of the more impactful things you can do for gut health — it removes a consistent source of inflammatory compounds that damage gut lining integrity over time.

But repair is a separate process from removal.

Fermented foods introduce beneficial bacteria and the byproducts of fermentation — organic acids, enzymes, and in some cases short-chain fatty acids — that support a diverse and functional gut microbiome. Before refrigeration, fermented foods were in virtually every traditional diet because they were how people preserved food. Their gut-health benefits were an accidental side effect of a practical necessity.

Fermented foods worth adding:

Raw sauerkraut — buy from the refrigerated section of a health food store (shelf-stable sauerkraut has been pasteurized and contains no live cultures) or make it yourself with cabbage and salt
Kimchi — check labels for seed oil additions; most traditional kimchi is clean
Plain yogurt or kefir — from full-fat grass-fed milk if available; the live cultures matter, so look for "live active cultures" on the label
Naturally fermented pickles — brine-fermented, not vinegar-pickled; look for "lacto-fermented" or check that the label lists no vinegar
Naturally fermented meat — beef sticks and other cured meats fermented through a natural lactic acid process, rather than preserved with chemical nitrates

The distinction on the last point is worth expanding. Most commercial beef jerky and meat sticks use sodium nitrate as a preservative. Naturally fermented beef sticks use lactic acid fermentation, which creates an acidic environment that preserves the meat without synthetic preservatives and adds the gut-health benefits of fermentation. It is a meaningful difference, both in what you're consuming and in what it does for you.

Fat-Soluble Vitamins: The Nutrients That Only Work With Good Fat

Vitamins A, D, E, and K2 are fat-soluble — they require dietary fat to be absorbed. This means that:

A low-fat diet is almost always deficient in these vitamins
A diet rich in the wrong fats (highly processed seed oils that oxidize easily) compromises absorption
A diet with adequate quality fat from animal and plant sources absorbs these vitamins efficiently

When you switch to clean cooking fats — butter, ghee, tallow, avocado oil — you are not just reducing harmful compounds. You are creating the physiological conditions to actually absorb the fat-soluble vitamins in the food you eat.

But you still need the vitamins in the food. The main dietary sources:

Vitamin A (retinol): liver, egg yolks, cod liver oil, full-fat dairy from pastured animals
Vitamin D: fatty fish, pastured egg yolks, beef liver, cod liver oil (sunlight is the primary source for most people, but dietary D matters)
Vitamin K2: grass-fed full-fat dairy (especially hard cheese), egg yolks, chicken liver, natto (fermented soybeans, an acquired taste)
Vitamin E: while often discussed in the context of nuts and seeds, the most bioavailable forms come from animal fats, olive oil, and avocado

If you are eating plenty of clean fat but mainly from olive oil, coconut oil, and avocado oil — without animal fats from pastured sources — you may be absorbing fat-soluble vitamins efficiently but still not getting enough of them in your food.

Building the Optimization Plate

Putting this together practically, an optimized clean eating day looks less like a supplement protocol and more like an expanded food list:

Breakfast options:

Two to three pastured eggs cooked in butter, with whatever vegetables you like
Sardines or salmon on seed-oil-free crackers with avocado
Bone broth as a morning drink alongside a protein-based meal

Lunch and dinner:

Prioritize grass-fed red meat or pastured poultry two to three times per week
Swap boneless chicken breast occasionally for skin-on, bone-in thighs or drumsticks — more collagen, more flavor, similar cost
Incorporate slow-cooked cuts once a week (short ribs, chuck roast, oxtail)
Add two to three servings of wild-caught fatty fish per week
Small portion of fermented food with at least one meal per day

Snacks:

Grass-fed beef sticks for portable protein that covers your between-meal needs without requiring a decision
Hard cheese from grass-fed sources
Hard-boiled eggs

Once or twice a week:

A small portion of beef liver (two to four ounces, cooked with butter and onions) covers your B vitamin and vitamin A needs for several days

The goal is not complexity. It is getting away from the idea that clean eating means eating less and more carefully — and toward the understanding that it means eating more of the right things.

The Second Step Is Simpler Than the First

Quitting seed oils required reading labels, finding new brands, and relearning what you could actually buy at the grocery store. That is genuinely difficult to navigate at first.

The optimization phase is more intuitive: eat the whole animal, not just the muscle meat. Eat fermented foods. Eat fatty wild fish regularly. Prioritize food from animals that ate what they were supposed to eat.

These are not new ideas. They are the ideas that every traditional food culture arrived at independently — before industrial food convinced two generations of people that convenience and shelf stability were the correct metrics for food quality.

You already did the hard part. Now comes the part where the food actually tastes good.
