To determine if the man has ingested his recommended allowance of protein, we must first calculate his recommended protein intake. According to the Institute of Medicine, the daily recommended intake of protein for an adult male is 0.8 grams per kilogram of body weight.

Converting the man's weight from pounds to kilograms:

154 pounds ÷ 2.2 = 70 kilograms

Multiplying his weight by the recommended protein intake:

70 kg x 0.8 g/kg = 56 grams of protein

Therefore, the man needs 56 grams of protein per day to meet his recommended intake.

If two-thirds of the man's protein comes from animal sources, he is consuming:

45 g x (2/3) = 30 grams of animal protein

To determine how much protein the man is getting from non-animal sources:

45 g total protein - 30 g animal protein = 15 grams of non-animal protein

Adding the animal and non-animal protein together:

30 g animal protein + 15 g non-animal protein = 45 grams of total protein

The man is consuming 45 grams of protein per day, but he needs 56 grams to meet his recommended intake.

56 g recommended protein - 45 g consumed protein = 11 grams of additional protein needed

Therefore, the correct answer is C, he needs 11 grams more protein to meet the recommended allowance. To determine if he has met his recommended allowance of protein, we need to know his specific requirement based on his weight. Assuming a moderate activity level, his recommended protein intake would be around 77-115 grams per day. Since he is consuming only 45 grams, he is not meeting his recommended allowance. 
If two-thirds of the protein comes from animal sources, he is getting 30 grams from animal sources. This means he needs an additional 11 grams of protein from non-animal sources to meet the lower end of his recommended intake. Thus, the correct answer is C.
