According to a 2023 study published on the website of Hannah Eden Fitness, a high-protein diet increases the body's need for water due to increased urea production. The question, "Does high protein cause water loss?" is a valid concern for anyone increasing their protein intake, and understanding the metabolic process is key to staying hydrated and healthy.

A 2025 study found that bronze whaler shark meat contained mercury levels up to eight times higher than the US EPA's reference dose limit, raising serious health concerns. When considering what is shark meat full of, the answer points to significant levels of contaminants, including heavy metals, alongside beneficial nutrients.

Nitrogen is the fourth most abundant element in the human body, making up about 3% of our total mass. It is a fundamental building block of life, playing a central and multifaceted role beyond just being part of the air we breathe. This essential element is critical for synthesizing the molecules that sustain all cellular functions.

Despite being a key component of urine, a solution that contains many electrolytes, urea itself does not conduct electricity when dissolved in water. This surprising fact clarifies that urea is, in fact, a non-electrolyte under standard conditions.

Over 100 million sharks are killed annually, yet the question remains: is shark good for humans to eat? As apex predators, sharks accumulate high levels of heavy metals like mercury, presenting significant health dangers to anyone who consumes them.

According to the Food and Agriculture Organization (FAO), urea was first used to supplement ruminant feeds in the early 20th century. The compound is the most common example of a non-protein nitrogen (NPN) source, a category of substances that can be converted into true protein by microbes in the rumen. This makes urea a cost-effective and crucial component in the diets of cattle, sheep, and other ruminant animals, particularly when natural protein sources are scarce or expensive.

According to one source, non-protein nitrogen (NPN) can comprise 20-30% of the total nitrogen in field grass, highlighting its prevalence and importance beyond conventional protein. So, what are non-protein sources of nitrogen, and why do they play such a significant role in both biology and agriculture?

In human milk, non-protein nitrogen can constitute between 20% and 50% of the total nitrogen content, while in bovine milk, it's typically less than 5%. This significant difference highlights the variable nature of nitrogenous compounds and sets the stage for a deeper look into the components that make up non-protein nitrogen.

Did you know that commercially available urea contains approximately 46% nitrogen by weight, making it the most concentrated solid nitrogen fertilizer on the market? This chemical compound provides essential nutrients found in urea through a biological process that fuels plant development and lush vegetative growth.

Oral urea has a history of medical use, particularly for treating conditions like hyponatremia, though it is not a common supplement. The question, **can you take urea orally**, depends entirely on the context and should only be done under strict medical supervision.
