Sentence Elimination- Our Protein Needs

  1. In fact, compared to other mammals, humans are actually naturally adapted for a relatively low protein intake, requiring protein to make up just 10% of our daily calorie requirement.
  2. Over the past 50 years, research has consistently found that whenever we tinker with our natural protein needs, it can have adverse consequences, at all phases of our lives.
  3. This became associated with an increased risk of developing chronic diseases such as cancer in later life, forcing the formula to be adapted to have a lower protein content.
  4. Human breast milk is quite low in protein: when cow’s milk formula was first used to create an artificial replacement for breast milk, the excessive protein content was found to cause accelerated growth rates in early life.


  • Correct Answer
    Choice A

Detailed Solution

Both sentences A and B seem to be loosely related, as they talk of our protein needs--A, about how our relatively low protein requirement compared to mammals, and B, about the adverse consequences of tinkering with our natural needs.

There is also an obvious link between sentences C and D, in that both relate to formula milk. D talks of how cow's milk formula containing excessive protein was found to cause rapid growth rate in early life, and C relates the effect of this in later life. DC is a strong link.

Now, sentence A compares our protein needs to that of other mammals. Though cows are mammals and the sentence group DC compares human milk to cow's milk, ADC does not make a cogent paragraph, as the focus of A is on how small a percentage of protein we need to make up our calorie requirement.

However, sentence B, which speaks of the adverse consequences of tinkering with our natural protein needs fits right in with the message in the sentence group DC. BDC makes a cogent paragraph.

So, sentence A is the odd one out.

Correct Answer: Choice (A)
