Atkins: Low-Carb and High in Antioxidants

February 6, 2015

You probably don’t think of Atkins as a high-antioxidant
diet, but by the time you finish reading this blog, you probably will. First,
before getting to know antioxidants, lets learn about free radicals. We need oxygen
to live, but byproducts resulting from the body’s oxidizing processes, called
free radicals, can damage our cells, causing aging, tissue damage and
inflammation. They’re also implicated in many disease states. These dangerous
agents are called free radicals because they are molecules with an unpaired
electron looking to bond with another electron in your body. Free radicals in
your cells are the result of stress (both emotional and physical), pesticides
and other chemicals in the environment, including cigarette smoke and burnt
foods. Even if you’re fortunate enough not to be exposed to some or all of the
above, aerobic exercise and the normal metabolic processes of your body also
produce free radicals. That’s where antioxidants, which can neutralize the
damaging effects of free radicals, come in. Antioxidants also protect against a
variety of disease states and generally delay the effects of aging.

The

Queen of Antioxidants

Researchers at the U.S. Department of Agriculture (USDA)
laboratory at Tufts University rank blueberries as Numero Uno in antioxidant
activity, in comparison to 40 other common fresh fruits and vegetables. Next up
are strawberries, kale and spinach.

A

Multitude of Others

Like vitamins and minerals, antioxidants are health-protective

micronutrients found in foods. There’s no shortage of antioxidants to battle

the evil forces of free radicals, although we still don’t understand whether we

need all of them for optimal health. Here is a just a short list of

antioxidants you have probably already heard of:

· Vitamin C

· Vitamin E

· Bioflavonoids

· Carotenoids

· Selenium

· Glutathione

· N-Acetyl cysteine

· Taurine

· Alpha-lipoic acid

· Co-enzyme Q10

Rather than take all these items individually, you’re better

off taking a daily multivitamin/mineral that includes a good mix of

antioxidants. But supplements are never a substitute for whole foods. Many of

these protective agents are found in common foods. As you’ll soon see, many

foods turn up repeatedly as sources for different antioxidants, evidence that getting

them in food, where they are in balance with other antioxidants, is advisable.

In fact, almost all these food sources of antioxidants are
among the basic foods of the Atkins Diet. Your best antioxidant-rich strategy?
Make sure you’re consuming at least 12 to 15 grams of Net Carbs in the form of
foundation vegetables on Atkins 20 and Atkins 40. We’ll show you where to find
the best (and worst) sources of antioxidants, so you can maintain your low-carb
lifestyle:

Vitamin

C

Find it in cabbage,
bell peppers, broccoli, Brussels sprouts, strawberries, cantaloupe, citrus
fruits, mango, kiwi and papaya. Avoid OJ and other citrus juices, which are
high in sugar and therefore high in carbs.

Vitamin

E

There are several chemical forms of vitamin E, and the two
main types are alpha-tycopherol and gamma-tycopherol. The former is found in
nuts, seeds, vegetables and vegetable oils, although the most concentrated
source is wheat-germ oil. Canola oil is a good source of the latter type of
vitamin E. Avoid corn and other vegetable oils as they are very high in omega-6
fatty acids, which we all get more than enough of compared to omega-3s.

Bioflavonoids

These plant pigments include quercetin and lutein, which are
both important for eye health. Good vegetable sources include red onions, green
cabbage, spinach, kale, onions and garlic. Fruit sources include cherries,
white grapefruit, apples, pears, grapes and cranberries.

Carotenoids

These, too, are vegetable and fruit pigments in vegetables.
Although beta-carotene is the best known, it is only one of about 600 different
carotenoids. Certain carotenoids are found in orange vegetables, including
pumpkins, which are acceptable in Phase 1, during Atkins 20. In later phases of
the diet (or if you’re doing Atkins 40), sweet potatoes, carrots and winter
squash are also excellent sources. Fortunately, some dark green veggies are
also carotenoid contenders: think of bitter greens such as kale, spinach,
chard, watercress, turnip greens, mustard greens, collard greens, dandelion
greens and beet greens. Your body absorbs and utilizes carotenoids better when served
with fat, so add a pat of butter to cooked greens or toss dark salad greens
with olive oil. Some orange fruits will also supply you with carotenoids,
although, with the exception of cantaloupe, most are Atkins acceptable only in
later phases (or Atkins 40): apricots, mangos and guava. Other carotenoids are found in
yellow-pigmented vegetables.

Selenium

Selenium is
thought to delay or prevent the onset of cancer and also has potent anti-aging
benefits. Brazil nuts have the highest level of selenium (don’t overdo
consumption), but other nuts, including walnuts and peanuts, are excellent
sources, as well. Other foods that provide this antioxidant are animal
products: beef, chicken, seafood, eggs and cheese. Additionally, for those at
later phases of Atkins, soybeans and other legumes and wheat, rice, corn, wheat
and oats are sources.

Glutathione

Unlike
most other antioxidants, you will not find glutathione in foods. Your body
makes it from another substance found in most vegetables and fruits:
glutathione peroxidase. The following Atkins-friendly foods help your body make
more glutathione: avocado, asparagus, broccoli, garlic, spinach
and tomatoes. The spice turmeric, which is a
source of curcumin, also helps boost your body’s production.

N-acetyl

cysteine (NAC)

In addition to its own antioxidant properties—it is particularly
important for retinal health—NAC increases the production of glutathione.
Anyone following Atkins is almost certainly consuming plenty of this
antioxidant because the best sources include poultry, yogurt, egg yolks, red peppers, garlic, onions, broccoli and Brussels sprouts. Oats
and wheat germ are also excellent sources.

Taurine

The best food sources of taurine are cold-water fish such as salmon
and cod, which are also rich in omega-3 fatty acids, which themselves act as
antioxidants. Taurine is also found in eggs, other seafood and milk. Vegans
need to take care to get sufficient taurine.

Alpha-lipoic

acid (ALA)

In addition to its role as an antioxidant, ALA helps convert blood glucose
into energy. It has also been shown to improve insulin sensitivity in type-2
diabetics. Alpha-lipoic acid can be found in broccoli, collard greens, chard and spinach, all of which
also contain other antioxidants.

Co-enzyme Q10 (Co10)

Essential
to heart health, this antioxidant is primarily found in fish (sardines and mackerel
particularly); beef, lamb and pork; and eggs. Although spinach and broccoli
supply some CoQ10, it is significantly less than fish and meat. Peanuts, wheat
germ and whole grains provide still less.

Fortunately, on Atkins, you’ll naturally get

plenty of health-protective antioxidants, while enjoying whole foods.
