Nitrogen is the fourth most abundant element in the human body, following carbon, hydrogen, and oxygen. While we cannot absorb the atmospheric nitrogen we breathe directly, it is absolutely essential for our survival in other forms, making the statement 'True'. It is a critical building block for proteins, DNA, and numerous other vital biological compounds.

Over 90% of a cell's energy is produced in its mitochondria. So, do we get energy from food True or false? The definitive answer is that food is the foundational source of fuel that powers every cellular activity in your body, from thought to movement.

Discovered in egg yolks in 1845, lecithin has long been central to both food science and biology. The statement, “Is lecithin a phospholipid?”, is often misunderstood, but the scientific answer is clear and fundamental to understanding its widespread functions.

Ethanol, also known as ethyl alcohol, is a naturally occurring chemical compound produced during the fermentation of sugars by yeast. Therefore, the statement that ethanol is the type of alcohol found in alcoholic beverages is true. While there are many types of alcohol, ethanol is the only one safe for human consumption, and even it is toxic in large quantities.

According to the U.S. Department of Agriculture (USDA), one gram of carbohydrate provides 4 calories, not 9. Therefore, the statement claiming carbohydrates have 9 calories per gram, fat has 4, and protein has 9 is factually incorrect and entirely false.

According to the National Institutes of Health, the term vitamin E is a collective name for a group of fat-soluble compounds with distinct antioxidant activities. This definitive guide will address whether tocopherols fall under this umbrella and explain the nuances of this vitamin family.

According to a study published by the NIH, feeding unsaturated fat to monogastric animals can increase the unsaturated fatty-acid content in their tissue lipids. The statement "Are unsaturated fats found in animal-based foods and are solids at room temperature?" is ultimately false, as unsaturated fats are typically liquid at room temperature due to their chemical structure.

According to the Food and Agriculture Organization (FAO), most naturally occurring foods are complex mixtures of nutrients, not single-nutrient sources. This debunks the simple idea that a food item, like a banana, is 'just' a carbohydrate source, revealing a more complex and holistic nutritional picture.

According to the World Health Organization, micronutrient deficiencies are a widespread public health issue, but this fact can be misleading, as most vitamins are required in very small quantities for normal metabolic function. The popular misconception that 'if a little is good, a lot must be better' is dangerous and scientifically unfounded when it comes to vitamin intake.

False: the statement 'Is fructose a monosaccharide? True or false?' is a trick question, as the correct answer is true. Fructose, often called fruit sugar, is a naturally occurring simple sugar or monosaccharide, which is a fundamental unit of carbohydrates. It is one of the three primary dietary monosaccharides, along with glucose and galactose, and is the sweetest of all naturally occurring carbohydrates.
