Different type of query

I have a table like this:

usda=# \d nutrient_data           Table "public.nutrient_data"    Column      |         Type          | Modifiers

when I run this query:select ndb_no, nutrient_no, nutrient_value from nutrient_data where 
ndb_no = 13473;

it produces:
ndb_no | nutrient_no | nutrient_value
--------+-------------+---------------- 13473 |         203 |          24.18 13473 |         204 |          15.93 13473

401|              0 13473 |         404 |          0.101
 


I want only certain nutrient_no (say 8 of them) and the nutrient values 
by ndb_no.

how would I write that query.  BIG THANKS in advance as I'm lost on this 
one.
