new research debunks trad views on nutrition

[Perris]

The article entirely skip the debate about the difference in content of fat-soluble vitamins which would have put full fat milk at advantage.
Often, missing vitamins are added to skimmed milk later, but synthetic vitamins belong to processed foods so they kept this issue out of the discussion on purpose.

Not quite. "Tom Sanders, a professor emeritus of nutrition and dietetics at King’s College London, says that while the amount of vitamin A in semi-skimmed milk is half the level found in full-fat milk" (because it's half the fat, doh!), but I agree it glosses over nutritional losses in semi and skimmed milk, for whatever reason (I think that was to simplify things, not deliberately to avoid getting into the weeds of definitions of 'processed' foods).

 

[Penpal]

On the subject of milk, 3.5% fat is actually low fat. When cows were left on pasture their milk changed as the grasses changed. Their milk fat would go up to 7%, 8%, and higher.

You should never drink skim milk. 2% fat is as low as you should go or your body will not be able to use the calcium in the milk.

On the subject of milk, 3.5% fat is actually low fat. When cows were left on pasture their milk changed as the grasses changed. Their milk fat would go up to 7%, 8%, and higher.

True, according to analysis, our cows makes at least 5% fat.
3.5 is just a legal number meant for industry.

Exploring Chickens’ Sense of Taste: What They Can and Cannot Taste
Chickens rely on multiple senses to navigate their environment, including sight, smell, and touch. However, their sense of taste is less developed compared to mammals like humans and even other animals such as dogs or pigs. While chickens do have the ability to taste, their taste preferences and sensitivities are quite different from our own. This article explores how chickens experience taste, what flavors they can detect, and how it influences their feeding behavior.
Do Chickens Have Taste Buds?
Yes, chickens have taste buds, but significantly fewer than humans and many other species.
Humans have around 9,000 taste buds, which are distributed across the tongue and mouth.
Chickens have only about 240–350 taste buds, located primarily at the base and back of the tongue.
Unlike humans, chickens do not have taste buds on the tip of their tongue, meaning their initial contact with food is more about texture and smell than taste.
What Can Chickens Taste?
Despite their limited number of taste buds, chickens can detect several basic flavors. Their ability to differentiate between tastes is linked to survival, helping them avoid toxic or unpalatable foods.
1. Bitter – Highly Sensitive
Chickens are extremely sensitive to bitter tastes and will often reject bitter foods.
This sensitivity is thought to be a protective mechanism, as many toxic plants and substances taste bitter.
Foods that contain bitter compounds, such as citrus peels or strong herbs, are often avoided by chickens.
2. Sour – Moderately Sensitive
Chickens can detect sour flavors, which may help them identify spoiled or fermenting foods.
While they do not seem to have an aversion to all sour foods, they may avoid very acidic substances.
3. Salty – Limited Tolerance
Chickens can detect salt but are more sensitive to high concentrations than humans.
While small amounts of salt are essential for their diet, too much salt can be harmful or even toxic.
Chickens will generally avoid overly salty foods, though they may peck at mildly salty items out of curiosity.
4. Umami (Savory) – Likely Present
Some research suggests that chickens can recognize umami flavors, which are associated with protein-rich foods.
This is particularly useful as chickens require a high-protein diet, especially when growing or laying eggs.
Their preference for insects, mealworms, and other protein sources may be partially driven by their ability to detect umami.
What Chickens Cannot Taste
One of the biggest differences between chickens and humans is their lack of sweet taste receptors.
1. Sweet – Not Detectable
Unlike humans, chickens do not have receptors for sweetness and do not experience sugar the way we do.
They may still enjoy eating fruits like berries, melons, and apples, but this preference is likely due to water content, texture, and bright colors, rather than sweetness itself.
This means they will not crave or seek out sweet foods like humans or other animals might.
How Taste Affects Chickens' Eating Behavior
Sight and Smell Play a Bigger Role – Since chickens do not rely as heavily on taste, they use sight and smell to recognize and select food.
Trial and Error Learning – Chickens often peck at new foods and decide over time whether they like them.
Foraging Instincts – Chickens prefer varied diets and will naturally explore different textures and flavors, but they avoid bitter and overly salty items.
Preference for Familiar Foods – If chickens are raised on a specific diet, they may initially reject new foods, even if they are nutritious.
Practical Implications for Poultry Keepers
Understanding chickens’ sense of taste can help poultry keepers make informed decisions about feeding:
Avoid feeding excessive salt – Processed or salty foods should be avoided.
Be mindful of bitter foods – Strongly bitter herbs, peels, or additives may not be well-received.
Use umami-rich treats for nutrition – Insects, mealworms, or protein-rich scraps can be excellent treats.
Introduce new foods gradually – Chickens learn by trial and error, so patience is key when introducing dietary changes.
Remember
While chickens have a sense of taste, it is less developed than in humans. They are highly sensitive to bitter flavors, moderately aware of sour and salty tastes, and likely detect umami, but they do not taste sweetness. Instead of relying on taste alone, chickens use sight, smell, and learned behavior to determine what to eat. By understanding their taste preferences and aversions, poultry keepers can make better feeding choices to ensure a healthy and well-balanced diet for their flocks.

This is very interesting.
Two things that constantly surprise me about my chickens is their apparent ability to detect calcium (they show no interest in egg shells when they are not laying) and protein (if I have a choice of a 16% or a 20% feed, or if I have a mix of kitchen scraps with some high protein scraps, they without fail go for the protein first).

This is outdated. I am away at present but will discuss when back with resources to hand to ensure I don't mislead or misremember current science on avian sense of taste.
