Food Fads
Kale!
Seaweed! Goji berries! When you hear aboout a food that curbs this disease or
that condition, you might want to dive right in. If some is good, more must be
better, right? Not so fast. The right amount of the right types of foods is
great for you. But if you overdo it or choose the wrong kinds, it can backfire.
Since every good-for-you-food has its limits, focus on the big picture.
Too Many Brazil Nuts
Selenium
is a nutrient that you need -- but only about 55 micrograms (mcg) of selenium a
day. Just one Brazil nut has 68-91 mcg. That's more than a day’s worth! Too
much selenium can cause problems including diarrhea, nausea, skin rashes, hair
loss, and even serious effects like trouble breathing, heart and kidney
failure, and heart attacks. Adults shouldn’t get more than 400 mcg per
day. That’s no more than four or five
Brazil nuts, if you don't get selenium from anything else.
Picking Your Own
Mushrooms
These
wild and wooly fungi are tasty, loaded with nutrients, low in calories, and may
even lower your risk of cancer. But
before you forage in your local forest, keep in mind that eating the wrong kind
of mushroom can lead to anything from an upset stomach to death. So only hunt
for them if you’re an expert or are with one. Otherwise, get them from your grocery
store to be safe.
Grapefruit Plus
Certain Meds
This
splashy citrus could cause problems if you have some prescriptions, like
statins for your cholesterol. Grapefruit can make your body absorb more of the
medicine than normal, which could lead to side effects. It may be more likely
with some statins than others. And the same thing could happen with some drugs
that treat other conditions. So if you’re gaga for grapefruit, ask your doctor
if it will affect your prescriptions.
Greens and Kidney
Stones?
Just
about everyone needs to eat more veggies. Dark, leafy greens like spinach are
some of the best. But if you tend to get kidney stones, you’ll want to watch
how much you eat. These greens have a lot of oxalate, which can cause kidney
stones. If you’re at risk, your doctor may recommend no more than 40-50
milligrams (mg) of oxalate a day. And half a cup of greens can have close to 10
mg of it. So you can have a couple of servings, but don’t pack huge amounts
into your green smoothies.
Too Much of the Wrong
Fish
Fish
are rich in protein, low in saturated fats, and high in good fats your body
needs. The catch? They absorb mercury. That’s a problem for anyone, but
especially pregnant women because it can harm the baby’s nervous system. Each
week, you can eat 12 ounces -- about two meals -- of low-mercury fish like
shrimp, canned light tuna, or salmon. Avoid high-mercury fish like:
King
mackerel
Orange
roughy
Shark
Swordfish
Tilefish
Can You Get Too Much
Water?
Most
days, you likely don’t drink enough of it. It's not easy to get too much. There
are two main exceptions. One is a mental health condition where you
compulsively drink water. The other is when you do a lot of hard exercise, like
marathons, and you down too much water instead of a sports drink.
Coconut Oil Overload
More
and more people have started to cook with coconut oil. But many nutritionists
are still skeptical. Why? While coconut oil does have fats that boost your good
cholesterol, it’s also bursting with saturated fat. Your best bet? Limit
yourself. The American Heart Association recommends no more than 13 grams of
saturated fat a day. Just 1 tablespoon of coconut oil gives you 11 of those.
Olive Oil: Drip,
Don’t Drown
Olive
oil may actually be good for your heart. But even the best fats are loaded with
calories. So limit yourself to 2 tablespoons a day or less, including what's in
your food. If you overdo it, you could
gain weight, and that could offset the good you thought you were doing.
Potatoes: Don’t Go
Green
Potatoes
naturally have solanine, a substance that can make you sick if you eat too
much. It’s highest in the eyes, sprouts, skin, and any green parts of the
potato. Still, you’d have to eat a lot of potatoes before you had a problem. A
person who weighs 100 pounds would need to eat 1 pound of completely green
potatoes before getting sick. But don’t forget to remove the eyes, sprouts, and
green parts, just to be on the safe side.
Nightshades and Joint
Pain
Potatoes,
tomatoes, eggplants, and peppers are all nightshades. They’ve gotten a bad rap
because of solanine. Some say it causes
joint pain, but there’s no research to back that up. In fact, yellow and purple
potatoes may help with swelling, which could ease pain. Still, you know your
body best. You may be sensitive to some vegetables, so if they bother you,
avoid them.
Maxed Out on
Chocolate
It
tastes great and has antioxidants and flavonoids, which can help lower your
blood pressure and protect your arteries. But there are limits: Go gourmet.
Lower-quality chocolate usually won’t have the flavonoids. Limit yourself to 1
ounce each day. Check the label of your bar to see how big it is.Stick
to dark chocolate that’s at least 70% cacao to avoid too much sugar and fat.
A Better Way
Make
it simple. Instead of obsessing over a single food:
Fill
half your plate with fruits and veggies. Split the other half between proteins
and whole grains.
Limit
how much sugar, salt, and saturated fat you eat.
Mix
it up. When you eat a variety of good-for-you foods, you meet your needs and
avoid overdoing it on any one thing.
