Yeah, I said it – real mayo. Open my fridge and you’ll find a small jar of original
Hellman’s. Not “light.” Not Miracle Whip. I’m talking the good stuff.
Does this surprise you? After all, mayo is, like, pure fat, amiright? (I am! I am so smart.)
Seriously though, poor fat. It’s been so maligned over the years. But the fact is, we need a certain
amount of dietary fat for energy, vitamin transport, and other important
functions. In fact, some types of
fat may actually reduce the risk of
heart disease. The key is knowing
which fats to choose:
Trans Fat: Public enemy #1 of the nutrition world. Trans
fats are added to foods during hydrogenation, a process in which fats are made
more shelf-stable by switching the position of hydrogen atoms. Trans
fats are uniquely bad because they raise LDL (bad) cholesterol and also lower
HDL (good) cholesterol. Try not to
eat anything that lists hydrogenated or partially hydrogenated oil as an
ingredient. (Note: the FDA does
not require products to be labeled as containing trans fat if they have less than 0.5 g/serving. For more information, visit the
FDA website on trans fat labeling.)

After hydrogenation -- note diagonal hydrogens |
Saturated Fat: The majority of research to date demonstrates that high intakes of saturated fat, which is mostly found in animal products like steak, bacon, cheese, eggs, and whole milk, raises LDL (bad) cholesterol. High levels of LDL cholesterol cause plaque to accumulate in your arteries, raising your risk of heart disease, high blood pressure, and stroke. Some lucky folks don’t appear to be affected by high sat-fat intakes, but some have exaggerated responses to the stuff. If you don’t know what kind of person you are (your parents generally serve as a pretty good reference point), it’s probably best to assume you’re somewhere in the middle. At least until you get your cholesterol tested at the doc’s office. (Really, go do it.)
The USDA recommends getting no more than 10% of your daily
calories from saturated fat. Gosh,
that’s helpful.
[Sarcasm]
In plain terms, if you eat about 2000 calories a day, try to
keep your sat fat intake under 22.2 g. (Math: 0.1 x 2000 = 200 cals; 200 cals x
[1g fat/9 cals per g] = 22.2 g fat)
Bottom line:
Don’t swear off steak. Just
choose a leaner cut, keep your portion reasonable, and don’t get it topped with
cheese and/or eggs and/or bacon.
(And from the Dept. of Interesting but Practically Useless
Information: Crisco consists of trans
fats; lard consists of saturated fats.
Lard, therefore, is the healthier choice.)
Mono- and
Polyunsaturated Fats: Yay, these fats are good for us! Monounsaturated and polyunsaturated fats
(MUFAs and PUFAs, and yes you can pronounce it like that) occur naturally in
some animal products but mostly in nuts and high-fat fruits like olives and
avocados (MUFAs), and salmon, eggs, soybean oil, flax seeds, and walnuts
(PUFAs).
So what the heck are
these things? Quick chem lesson
(quick, I promise!):
1 double bond in the chain |
A MUFA is a fatty
acid with only one double bond. If
a fatty acid doesn’t have any double bonds, it is saturated with hydrogen
atoms. This makes the molecule
stiff, which is why butter is solid at room temperature. With a double bond, fatty acids become
unsaturated because they lose some hydrogen atoms (2 per double bond, to be
exact). Double bonds add kinks to
a fatty acid chain, which makes the molecule more fluid. This is why oil is a liquid at room
temperature.
more than 1 double bond in the chain |
A PUFA is a fatty
acid with two or more double bonds.
PUFAs include omega-3s, omega-6s, and omega-9s. These three PUFAs are called essential
fatty acids because our bodies cannot synthesize them; we must obtain them from
the diet. Like MUFAs, PUFAs are
liquid at room temperature.
Generally speaking, we all could use some more omega-3s in
our diet. These guys are so
awesome because they lower LDL (bad) cholesterol and raise HDL (good)
cholesterol. Omega-3s are like the
opposite of trans fats.
As for omega-6s and 9s, don’t worry too much about them. Chances are you’re getting plenty without
even trying. Definitely don’t buy
omega-9 supplements -- biggest waste of money ever!

So where were we?
Oh, yes – mayo.
Hellman’s Real Mayonnaise contains: soybean oil, water,
whole eggs and egg yolks, vinegar, salt, sugar, lemon juice, calcium disodium
EDTA (used to protect quality), and natural flavors.
Soybean oil is a healthy PUFA. Egg yolks contain omega-3s. The other ingredients are nutritionally negligible. Of the 10g of fat per tablespoon serving,
only 1.5g are saturated. 6g are
PUFAs and 2.5g are MUFAs.
For comparison’s sake, Hellman’s Light Mayonnaise contains: water,
soybean oil, vinegar, modified corn starch, whole eggs and egg yolks, sugar,
salt, xanthan gum, lemon and lime peel fibers (thickeners), (sorbic acid,
calcium disodium EDTA) used to protect quality, lemon juice concentrate,
phosphoric acid, dl alpha tocopheryl acetate (vitamin e), natural flavors,
beta carotene.
That’s a lot of ingredients there. Most of the additions are thickening agents used to make up
for the loss of texture from fat.
Not bad, but you might have to use twice the amount of light mayo to
achieve the same mouthfeel as regular.
Best bet? Buy
mayo with the least amount of ingredients you can find (or, if you’re
superhuman, make
your own). Then, use half as
much as you would of the light stuff.
And enjoy, for God’s sake – the real stuff is so much better!
