The goal of a "right fat" diet is to eat the right amount of the right kinds of oil. We have used these criteria for evaluating the various types of oil:
The fact that some oils rank higher than others does not mean that you should consume only the one or two at the top of the list. Balance is still the key to good nutrition, and nutrition depends on variety.
BEST OILS
1. Flaxseed
COMMENTS
Best source of omega 3 fatty acids; has heart-
healthy properties; is a colon-friendly oil;
lessens constipation; boosts immunity;
promotes healthy skin; contains the healthy
phytonutrient, lignin; spoils quickly without
careful storage; not to be used in cooking
2. Canola
One of the lowest oils in saturated fats, making
it a heart-friendly oil; a rich source of essential
omega 3 and 6 fatty acids.
3. Soybean
Contains both omega 3 and omega 6 fatty
acids, but is often highly refined and
hydrogenated.
4. Olive oil (virgin or extra virgin)
Doesn't need high temperature or chemical
processing, since it is made from the flesh of
the olive and not the seed; slow to spoil; okay
for medium-temperature cooking; in
moderation lowers LDL (bad) cholesterol
without affecting HDL, (good) cholesterol
thereby improving the HDL-to-LDL ratio.
5. Pumpkin seed
Low in saturated fats; rich in omega-6 fatty
acids, may contain some omega 3's; refining
and chemical processing lowers the nutritional
qualities.
MEDIUM OILS
COMMENTS
1. Safflower
Low in saturated fats, rich in omega 6 fatty
acids.
2. Sunflower
Rich in omega 6 fatty acids.
3. Corn
Slightly higher in saturated fats than the best
oils; usually hydrogenated; rich source of
omega 6 fatty acids
4. Peanut
Somewhat high in saturated fats but still less
than butter, animal fat, and cottonseed oil;
good for cooking at higher temperatures.
WORST OILS
COMMENTS
1. Cottonseed
High in saturated fats; likely to contain
pesticide residues; frequently hydrogenated.
2. Palm kernel
High in saturated fats, therefore a potentially
cholesterol-raising oil.
