Healthy Animal Oil

Below is a clear, evidence-based ranking of common animal cooking fats from healthiest to least healthy when used in moderation as part of a normal diet.

Rank

Fat/oil

Why it ranks where it does

Main concerns (if any)

Best uses in practice

1

Fatty fish oil (used as supplement or from cooking salmon, mackerel, sardines)

Extremely high in omega-3 EPA/DHA → proven to lower triglycerides, reduce inflammation, protect heart & brain.

Almost none if from clean fish

Eating the fish itself or supplements

2

Goose fat

≈60–65 % monounsaturated (same as olive oil), decent stearic acid (neutral), low PUFA. Very stable when heated.

High calories, but excellent fatty-acid profile

Roast potatoes, vegetables

3

Duck fat

Almost identical profile to goose fat (60 %+ MUFA), high oleic acid, very heat-stable.

Same as goose

Confit, roasting, frying

4

Beef tallow / drippings

≈50–55 % MUFA + high stearic acid (doesn’t raise LDL), conjugated linoleic acid (CLA) in grass-fed. Very stable.

Slightly higher SFA than goose/duck

Roasting, Yorkshire puddings, frying

5

Butter (especially grass-fed)

Contains butyrate (anti-inflammatory), CLA, vitamins A/D/K2, some short/medium-chain fats. ~60–65 % SFA but many are neutral/beneficial.

High in saturated fat (still debated)

Low–medium heat, baking, finishing

6

Ghee (clarified butter)

Same as butter but lactose/casein removed, slightly higher smoke point.

Same saturated-fat debate as butter

High-heat Indian cooking, roasting

7

Lard (pork fat)

Traditional leaf lard is ~50 % MUFA, 40 % SFA, 10 % PUFA. Very stable. Pasture-raised is better.

Factory-farmed lard can be higher in omega-6

Pie crusts, frying, confit

8

Chicken fat (schmaltz)

Higher in PUFA (~20–25 %) and omega-6 than the ones above → more prone to oxidation when overheated.

Higher omega-6, less stable

Traditional Jewish/European cooking

9

Regular supermarket butter flavored with omega-6 oils (some “spreadable” butters)

Often blended with cheap seed oils → worse fatty-acid balance.

Added refined seed oils

Avoid if possible

Quick summary (healthiest → least healthy)

1. Fatty fish (omega-3 powerhouse)  

2–4. Goose fat ≈ Duck fat > Beef tallow (all very high in stable monounsaturated fat)  

5–6. Grass-fed butter / ghee  

7. Good-quality lard (leaf lard from pasture pigs)  

8–9. Chicken fat and cheap blended butters (higher omega-6, less stable)


Bottom line for everyday cooking

If you’re choosing purely for cardiovascular and metabolic health and you cook at high temperatures:  

Goose fat, duck fat, or grass-fed beef tallow are probably the three healthiest animal fats you can buy in a supermarket.  

Butter/ghee are excellent too, especially at lower heat or as a flavor finisher.


All of them are vastly better than refined seed oils (sunflower, soybean, corn, “vegetable” oil) when you look at real-world outcomes and oxidative stability.


Practical rule of thumb you can use in any supermarket

Healthier choices (use freely):

  • Extra-virgin olive oil
  • Avocado oil
  • Goose fat, duck fat, beef tallow
  • Real butter or ghee
  • Coconut oil (if you like the taste)

Avoid or use only occasionally:

  • “Vegetable oil”, sunflower, corn, soybean, canola, grapeseed, rice-bran, cottonseed, etc.

So no — plant-based does NOT automatically mean healthier. In fact, the average bottle labelled “vegetable oil” or “heart-healthy canola” in a UK supermarket is one of the worst fats you can cook with regularly.

why spring onions sold in UK withers very quickly upon regrowing in water

Image
  The spring onions (also called salad onions or scallions in the UK) you buy in supermarkets are not meant to live long-term — they’re essentially “cut-and-come-again” crops that have been forced to grow very quickly in perfect commercial conditions. When you try to regrow them at home in a jar of water, the leaves often collapse and wither quite dramatically (exactly like in your photo). Here’s why this happens in the UK (and elsewhere): 1. They’ve already used up most of their energy Supermarket spring onions are harvested when the bulb is still tiny. Almost all the stored energy is in the small white base, and the green leaves are very long and thin. Once cut from the field, that tiny bulb has to support those huge leaves withering leaves with no photosynthesis happening (because they were often stored in the dark). By the time you get them home, the bulb is already running on fumes. 2. UK supermarket varieties are chosen for shelf-life, not re-growability The varieties...

Excel Function: TextSplit

Image
Syntax =TEXTSPLIT(text,col_delimiter,[row_delimiter],[ignore_empty], [match_mode], [pad_with]) The TEXTSPLIT function syntax has the following arguments: text        The text you want to split. Required.  col_delimiter        The text that marks the point where to spill the text across columns. row_delimiter        The text that marks the point where to spill the text down rows. Optional. ignore_empty        Specify TRUE to ignore consecutive delimiters. Defaults to FALSE, which creates an empty cell. Optional. match_mode     Specify 1 to perform a case-insensitive match. Defaults to 0, which does a case-sensitive match. Optional. pad_with            The value with which to pad the result. The default is #N/A. Remarks If there is more than one delimiter, then an array constant must be used. For example, to split by both...
