Default 7 Nutrients That You Canít Get From Plants

Condensed from a longer article...

7 Nutrients That You Canít Get From Plants

1. Vitamin B12

Vitamin B12 is an essential nutrient that's almost exclusively found in animal-sourced foods, such as fish, meat, dairy products, and eggs.

Also known as cobalamin, it's a water-soluble nutrient involved in developing red blood cells and maintaining nerves and normal brain function.

Studies have shown that without supplements or enriched foods, vegetarians are at a high risk of vitamin B12 deficiency.

2. Creatine

Creatine is a molecule found in animal foods.

Most of it is stored in muscles but significant amounts are also concentrated in the brain.

It functions as an easily accessible energy reserve for muscle cells, giving them greater strength and endurance.

For this reason, it's one of the world's most popular supplements for muscle building.

Studies show that creatine supplements can increase both muscle mass and strength.

Creatine is not essential in your diet, as it can be produced by your liver. However, studies have shown that vegetarians tend to have lower amounts of creatine in their muscles.

One study placed people on a lacto-ovo-vegetarian diet for 26 days and found that doing so caused a significant decrease in their muscle creatine levels.

3. Carnosine

Carnosine is an antioxidant that's concentrated in the muscles and brain of humans and animals.

It's very important for muscle function, and high levels of carnosine in muscles are linked to reduced muscle fatigue and improved performance.

Carnosine is only found in animal-based foods.

4. Vitamin D3 (Cholecalciferol)


Vitamin D is an essential nutrient with many important functions.

Also called the sunshine vitamin, vitamin D doesn't have to come from your diet.

Your skin can produce it when it's exposed to sunlight. However, if your sunlight exposure is limited or you live far from the equator, you must get it from food or supplements.

There are two types of dietary vitamin D ó ergocalciferol (D2) found in plants and cholecalciferol (D3) found in animal-based foods.

Of these types, cholecalciferol (D3) increases blood levels of absorbable vitamin D much more efficiently than ergocalciferol (D2).

The best sources of vitamin D3 are fatty fish and egg yolks. Other sources include supplements, cod liver oil, or enriched foods like milk or cereals.

As the main dietary sources of vitamin D3 are not plant-based, vegetarians and vegans may be at a higher risk of deficiency.

5. Docosahexaenoic Acid (DHA)

Docosahexaenoic acid (DHA) is an essential omega-3 fatty acid that's important for normal brain development and function.

Deficiency in DHA can have adverse effects on mental health and brain function, especially in children.

In addition, inadequate DHA intake in pregnant women may adversely affect fetal brain development.

It's mainly found in fatty fish, fish oil, and certain types of microalgae.

In your body, DHA can also be made from the omega-3 fatty acid ALA, which is found in high amounts in flax seeds, chia seeds, and walnuts.

However, the conversion of ALA to DHA is very inefficient and may not increase blood levels of DHA sufficiently.

For this reason, vegetarians and vegans often have lower levels of DHA than meat eaters

6. Heme Iron

Heme iron is a type of iron only found in meat, especially red meat.

It's much better absorbed than non-heme iron, which is commonly found in plant foods.

Heme iron also improves your absorption of non-heme iron from plant foods. This phenomenon is not entirely understood but is called the "meat factor."

Non-heme iron is poorly absorbed, and its absorption can be limited further by antinutrients that are also present in plant foods, such as phytic acid.

Unlike non-heme iron, the absorption of heme iron is not affected by the presence of antinutrients.

For this reason, vegetarians and vegans ó especially women and people on raw food diets ó are more prone to anemia than meat eaters


7. Taurine

Taurine is a sulfur compound found in various body tissues, including your brain, heart, and kidneys.

While its bodily function is not entirely clear, it appears to play a role in muscle function, bile salt formation, and antioxidant defenses.

Taurine is only found in animal-sourced foods, such as fish, seafood, meat, poultry, and dairy products.

Subsequently, studies have shown that vegans have much lower levels of taurine than meat eaters.

It's not considered essential in the diet, as your body produces small amounts. Still, dietary taurine may play a role in maintaining your body's taurine levels.

Nice reminder as to why meat is the best place to get these nutrients!

Our bodies are designed to be omnivores, so it's important to eat both plants and animals.

There are other things in plants that you can't get from flesh.

Hmm, like what? I search a bit, and found stuff like starch, flavanoids, and even vitamin C.

It doesn't seem a well-sourced article, either:

and I have a minor in Arctic memoirs which quite firmly stated the Inuit, and the Europeans who adopted their ways, cured their scurvy by eating raw, fresh, meat.

Fiber, pectin, certain flavonoids, and a few others.

Some vitamins abundant in plants can be found in flesh or organ meats but in insufficient quantities.

It still makes sense for me to eat both plants and animals, but to be choosy about what I ingest.
