Kiwi

Kiwis contain between
90 and 110 milligrams of vitamin C — more than an average orange. They are a
good source of potassium, an important mineral for strong muscles and nerves,
plus immune-boosting vitamin E. They are also packed with flavonoids and carotenoids
— antioxidants that promote respiratory health, heart health and optimum
well-being, says Suki Hertz, M.S., R.D., nutrition professor at the Culinary
Institute of America. Cut kiwis in half and scoop out the flesh for a fruit
salad or mash up and stir into plain yogurt.

Papaya
Papayas are praised
for their anti-inflammatory properties. They're also an excellent source of
vitamin C—one medium papaya supplies 313 percent of your daily requirement,
explains Hertz. Additionally, they are a great source of beta-carotene, a
phytonutrient that gets converted to vitamin A in your body and keeps eyes,
skin and mucous membranes moist. Have a few slices for breakfast in the morning
or blend some with orange juice for a tropical smoothie.

Ginger
If you feel a cold
coming on ward it off with ginger, which can alleviate cold symptoms and clear
nasal passages. It also promotes digestive health, reduces gas pains and
relaxes the intestinal tract, explains Hertz. If you find yourself battling a
stomach bug or winter cold, try steeping slices of fresh ginger in hot water
for a soothing and healthy morning drink.

Pumpkin Seeds
Pumpkin seeds are
packed with vitamins, amino acids and minerals, including zinc. Zinc helps the
immune system by acting as an antioxidant and minimizing damage to cell
membranes from free radicals, explains Hertz. Pumpkin seeds are delicious alone
or sprinkled in yogurt, oatmeal or cereal. For a sweet and spicy breakfast on
the go, try this energy mix.


Wheat Germ
Full of essential
vitamins and fats, wheat germ, the nutrient source of the wheat grain, can help
give your immune system a boost. It's also high in vitamin E, an antioxidant
that helps fight inflammation, says Hertz. Sprinkle wheat germ in yogurt,
oatmeal or cold cereal.

Beets
Give your morning
glass of orange juice a boost by blending it with cooked beets — just remember
to strain it before serving. Packed with antioxidants and magnesium, a mineral
that assists with nerve and muscle function, beets are also especially rich in
folate. This B vitamin helps prevent serious birth defects and is important for
women of childbearing age and for heart health, explains Hertz.

Flax Seeds
Flax seeds are
chock-full of important nutrients and minerals, including vitamin E, an
antioxidant that keeps cells healthy, and alpha-linolenic acid, a vegetarian
source of omega-3 fatty acids. To obtain these healthy fats, flax seeds must be
ground first, explains Hertz. A coffee grinder works perfectly for this.
Famous for their nutty flavor, flax seeds can be sprinkled on yogurt, oatmeal or cold cereal. Flax oil is another option and a good way to add important nutrients to smoothies. Both flax seeds and flax oil are highly perishable and should be kept in the refrigerator for up to three months.

Lemons
Besides being packed
with vitamin C, lemons promote healthy bacteria, rather than the type that can
cause viruses and colds. Hertz suggests using lemon in place of sugar and salt,
both of which can weaken the immune system. In the morning, try squeezing some
on fresh fruit instead of sprinkling with sugar.

Blueberries
It's no wonder
blueberries are called a superfood — they have more antioxidants than any other
fruit or vegetable. They are also one of the highest-ranking foods in
anthocyanidins (cancer-fighting antioxidants) and are excellent sources of vitamin
C, manganese and fiber, says Hertz. Start your morning with this Greek yogurt
parfait, a beautiful dish that delivers a healthy mix of berries.

Eggs
Egg yolks are a good
source of selenium, a powerful mineral that supports a healthy immune system.
Research on eggs is proving they are not the heart-disease villains they were
once thought to be, explains Hertz. The protein in the whites is of the highest
value, and the yolks, although high in dietary cholesterol, are relatively low
in saturated fat.

Tofu
People who don't eat
enough protein tend to load up on carbs, which can increase blood sugar levels
and weaken the immune system. Tofu is a complete protein and a good source of
calcium and omega-3 fatty acids, all of which can strengthen the immune system,
says Hertz. For a high-protein drink that's good on the go, try this quick
smoothie.
Quinoa
Quinoa (pronounced
keen-wa) is commonly referred to as a grain, but it's actually a seed that can
be cooked. A super food, quinoa is one of the few "complete proteins"
of the plant world, meaning it supplies all of the essential amino acids that
are found in meat, poultry or fish, such as lysine, which helps with tissue
repair, says Hertz. In the morning, swap white or whole-wheat bread with a
multigrain loaf that's loaded with quinoa, bulgur and millet.

Grapefruit and Oranges
Everyone knows that
citrus is chock-full of vitamin C, and it's also packed with powerful
antioxidants and is low in calories, says Hertz. For a healthy breakfast that's
sure to strengthen your immune system, try a fruit salad that combines three
types.

Cottage Cheese
Cottage cheese
contains selenium, a powerful antioxidant that can strengthen the immune
system, says Hertz. To give your immune system a boost, try this breakfast
parfait which combines cottage cheese with vitamin C-rich papaya and wheat germ.
