Different type of query

I have a table like this:

usda=# \d nutrient_data
Table "public.nutrient_data"
Column | Type | Modifiers
-----------------+-----------------------+-----------
ndb_no | integer | not null
nutrient_no | integer | not null
nutrient_value | double precision | not null
data_points | double precision | not null
std_error | double precision |
src_cd | integer | not null
derivation_code | character varying(5) |
ref_ndb_no | integer |
add_nutr_mark | character varying(2) |
num_studies | integer |
min | double precision |
max | double precision |
df | numeric |
low_eb | double precision |
up_eb | double precision |
stat_cmt | character varying(15) |
cc | character varying(5) |
Indexes:
"nutrient_data_pkey" PRIMARY KEY, btree (ndb_no, nutrient_no)
Foreign-key constraints:
"nutrient_data_derivation_code_fkey" FOREIGN KEY (derivation_code)
REFERENCES derivation_code(derivation_code) ON UPDATE CASCADE ON DELETE
CASCADE
"nutrient_data_ndb_no_fkey" FOREIGN KEY (ndb_no) REFERENCES
food_description(ndb_no) ON UPDATE CASCADE ON DELETE CASCADE
"nutrient_data_nutrient_no_fkey" FOREIGN KEY (nutrient_no)
REFERENCES nutrient_definitions(nutrient_no) ON UPDATE CASCADE ON DELETE
CASCADE
"nutrient_data_src_cd_fkey" FOREIGN KEY (src_cd) REFERENCES
source_code(src_cd) ON UPDATE CASCADE ON DELETE CASCADE

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 | 205 | 0
13473 | 207 | 1.1
13473 | 208 | 247

13473 | 309 | 4.67
13473 | 312 | 0.131
13473 | 315 | 0.015
13473 | 317 | 10.9
13473 | 318 | 0
13473 | 319 | 0
13473 | 320 | 0
13473 | 321 | 0
13473 | 322 | 0
13473 | 323 | 0.18
13473 | 334 | 0
13473 | 337 | 0
13473 | 338 | 0
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.
