Ok... just as a short explanation... this is not schoolwork reading... this is my pleasure reading. I own the Small Animal Clinical Nutrition textbook, and it's my pleasure reading. Which is good I guess... considering I want to be a veterinarian.
So yeah. Something I read in it concerning the issue of malnutrition. Here's the section, interpret it how you want. This is simply a medical (albeit animal medical) textbook with the medical interpretation of what malnutrition really means.
Malnutrition is defined as any disorder of nutrition with inadequate or unbalanced nutrition. Many veterinarians and animal owners think only of nutrient deficiences when they hear the term malnutrition. Muscle wasting and a distended abdomen in a starving third-world child or a heavily parasitized puppy is often our first mental image of malnutrition. In first-world societies, however, malnutrition is usually due to overnutrition or excessive intake of nutrients. Obesity due to consumption of excessive levels of fat and calories is a common example of malnutrition in both people and their pets. Another example of malnutrition due to unbalanced nutrition is the developmental orthopedic disease seen in rapidly growing large- and giant-breed puppies as a result of excessive calcium and energy intake. Malnutrition due to either nutrient deficiencies or nutrient excesses can be harmful to dogs and cats.
And to people.
I dunno. I just found this... and it broadened my mind about nutrition in general. One thing you can do is to change "dog and cat" to something involving a human... because this directly applies to us as well.
Feel free to interpret this however you wish.
Just thought I'd share.
