Top 10 Foods Highest in Zinc

Zinc is an essential mineral required by the body for maintaining a sense of smell, keeping a healthy immune system, building proteins, triggering enzymes, and creating DNA. Zinc also helps the cells in your body communicate by functioning as a neurotransmitter. A deficiency in zinc can lead to stunted growth, diarrhea, impotence, hair loss, eye and skin lesions, impaired appetite, and depressed immunity. Conversely, consuming too much zinc can disrupt absorption of copper and iron, as well as create large amounts of toxic free radicals. The current RDA for Zinc is 15mg. Below is a list of the top ten foods highest in Zinc.
#1: Oysters

Depending on type and variety oysters provide 16-182mg of zinc per 100g serving. This accounts for 110%-1200% of the RDA for zinc. The food highest in zinc is The Steamed Wild Eastern Oyster which provides 182 mg of zinc per 100g serving, or 76mg (509% RDA) in 6 oysters, and 154mg (1029% RDA) in a 3 ounce serving.
#2: Toasted Wheat Germ

Packed in jars and sold toasted, wheat germ is great to sprinkle on top of any food. Try it on salads, rice, or steamed vegetables. Toasted wheat germ provides 17mg (112% RDA) of zinc per 100g serving, which is 19mg (126% RDA) per cup, and 1.2mg (8% RDA) in a single tablespoon. Crude (untoasted) wheat germ provides 12mg (82% RDA) of zinc per 100g serving, 14mg (94% RDA) per cup, and 1mg (6% RDA) per tablespoon.

#3: Veal Liver

The liver of any animal is packed with vitamins and minerals and most commonly served as pâté or liverwurst. Veal liver has the most zinc with 12mg per 100g serving accounting for 81% of the RDA, that is 8.98mg of zinc (60% RDA) in a cooked slice of liver (80g). Liver is best prepared steamed or fried with onions and herbs.

#4: Sesame Seeds and Tahini (Sesame Butter)

#5: Low Fat Roast Beef

Low fat beef shoulder, shank, and chuck all contain about 10mg (70% RDA) of zinc per 100g serving, 18mg (119% RDA) per pound, and 9mg (59% RDA) in a 3 oz serving. If you buy pre-processed roast beef be sure to consult the nutrition facts about the cut and nutrients. Not all nutrition labels report zinc, so don't worry if you don't see it.

#6: Roasted Pumpkin and Squash Seeds






A popular food in the Middle East and East Asia pumpkin and squash seeds contain about 10mg (70% RDA) of zinc per 100g serving, 6.6mg (59% RDA) per cup, and 3mg (19% RDA) per ounce (~85 seeds). If you can't find these in your local supermarket you will surely find them in Middle Eastern or East Asian specialty stores. Alternatively, you can also save any pumpkin and squash seeds you have and roast them in your oven. The seeds are typically eaten by cracking the outer shell and eating the seed inside.

#7: Dried Watermelon Seeds







Much like the pumpkin and squash, watermelon seeds are popular in the Middle East and East Asia and they should be in specialty stores catering to those cultures. It is also possible to just eat the seeds raw with the watermelon. You can shell them, or just chew them up whole. Dried watermelon seeds provide 10mg (70% RDA) of zinc per 100g serving, 11mg (74 %RDA) per cup, and 3mg (19% RDA) per ounce.

#8: Dark Chocolate and Cocoa Powder






Chocolate is showing more and more health benefits and dark chocolate is coming into vogue. Unsweetened baking chocolate provides 9.6mg (64% RDA) of zinc per 100g serving (most bars are 50-100 grams). Cocoa powder will provide 6.8mg (45% RDA) per 100g, or 5.4mg (39% RDA) per cup, 0.3mg (2% RDA) per tablespoon. Most milk chocolates provide around 2.3mg (15% RDA) per 100g serving or 1mg (7% RDA) per bar.

#9: Lamb (Mutton)






Lamb is a common meat in the Middle East, Mediterranean, and most of Europe, but is increasing in popularity in the Americas. Lamb provides between 4.2-8.7mg of zinc per 100g serving (28%-58% RDA) depending on cut. That is up to 7.4mg (49% RDA) in a 3 ounce serving (85 grams).

#10: Peanuts






Peanuts are a great source of zinc, 100 grams of oil roasted peanuts will provide 6.6mg (44% RDA) of zinc, or 8.8mg (59% RDA) in 1 cup chopped, 1.9mg (12% RDA) per oz (~39 peanuts). Dry roasted peanuts will provide half as much zinc at 3.3mg (22% RDA) per 100 gram serving, or 4.8mg (32% RDA) per cup, and 1mg (6% RDA) per oz.

Health Benefits of Zinc

• Healthy Immune Function - Even mild to moderate zinc deficiency can depress the immune system through impaired macrophage and neutrophil functions, and associated effects.³ Zinc is also essential for creation and activation of T-lymphocytes.^4,5 Further, low levels of zinc have been associated with increased susceptibility to pneumonia and other infections in children and the elderly.^6-9
• Alleviation of the Common Cold (*Controversial) - There are conflicting studies as to weather or not zinc supplements can alleviate symptoms of the common cold and shorten its duration. At least one study confirms decreased duration of cold symptoms compared to a control,¹⁰ however, other studies report no effect.^11,12 Since no harm is reported, increasing zinc intake could only help.
• Healing of Cuts and Wounds - Zinc is essential for healthy skin and maintenance of mucosal membranes. Adequate levels of zinc is necessary for proper wound healing.¹³
• Reduced Severity and Duration of Diarrhea - Studies show that increased intake of zinc can reduce duration and severity of diarrhea in undernourished children with infections.^14-17
• Prevention and Reduction of Age-Related Eye Damage - High dietary intake of zinc, as well as vitamins C, E, and beta-carotene, has been associated with reduced age-related macular deneration in the edlerly.¹⁸

High Risk Groups for a Zinc Deficiency

• Alcoholics - 30-50% of alcoholics have low levels of zinc because alcohol decreases zinc absorption and increases urinary secretion of zinc.
• Vegetarians - The bio-availability of zinc is higher in meats and thus more easily absorbed. Further legumes and whole grains contain phylates which bind zinc and inhibit absorption. (See lists of fruits and vegetables high in zinc.)
• Pregnant and Lactating Women - A developing fetus requires a high amount of zinc, likewise, there is a high amount of zinc lost through breast milk after birth.
• Older Infants who are Exclusively Breastfed - Infants older than 6 months should eat age-appropriate foods which provide zinc as the amount in breast milk is no longer ample.
• People with Sickle Cell Disease - For unknown reasons 44% of children, and 60-70% of adults with sickle cell disease have low levels of zinc.
• People with Gastrointestinal and Other Diseases -Gastrointestinal surgery, Crohn's disease, ulcerative colitis, short bowel syndrome, and other digestive diseases can all decrease zinc absorption and increase zinc loss from the body.
• People Consuming high Doses of Iron Supplements - Iron can interfere with zinc absorption, to reduce this effect, iron suppliments should be taken between meals to allow time for zinc to be absorbed properly.
• People taking Diuretics - Thiazide diuretics such as chlorthalidone (Hygroton®) and hydrochlorothiazide (Esidrix® and HydroDIURIL®)can increase zinc excretion by 60%, and over the long term, deplete body tissues of zinc stores. Be sure to consult your doctor or clinician to monitor your zinc level if you are taking these diuretics for a sustained period of time, and be sure to eat more zinc rich foods.

Warnings

• Oysters, liver, lamb, and cheese are high cholesterol foods which should be eaten in moderate amounts and avoided by people at risk of heart disease or stroke.
• Sesame Seeds, Pumpkin Seeds, Squash Seeds, and Peanuts are high calorie foods and should be eaten in moderate amounts by people with a high body mass index.
• Zinc suppliments have adverse reactions with the following medications:
  • Antibiotics - Certain antibiotics like quinolone antibiotics (such as Cipro®) and tetracycline antibiotics (such as Achromycin® and Sumycin®) inhibit the absorption of zinc in the digestive tract.
  • Penicillamine - Zinc reduces the absorption of Penicillamine, which is used by people suffering from rheumatoid arthritis. Taking zinc suppliments two hours before or after intake of Penicillamine solves this problem.

Oranges

 

WHY YOU NEED THEM

They'll keep your ticker beating at its ideal rhythm. That extra cardio protection comes from two compounds (hesperidin and naringin) found in the peel and inner white pulp. In studies, the duo have been shown to potentially ward off heart disease and stroke by elevating levels of good cholesterol while reducing the risk of clots.

Oranges fi ght off damage from the sun. Orange peel is loaded with the protective phytonutrient d-limonene. Eating as little as one tablespoon of orange zest each week—about the amount from one orange peel—can significantly suppress your risk for skin cancer. For the greatest effect, combine orange zest with hot black tea.

NOTE: To get zest, rub an unpeeled orange against a food grater with fine holes. The resulting bits of peel—or zest—can be used in salads or soups or sprinkled over chicken or fish before cooking.

Citrus fruits may fight the signs of aging. The vitamin C in oranges can neutralize free radicals, preventing them from damaging cells and triggering everything from fi ne lines and wrinkles to more serious illnesses like cancer. And just taking a supplement won't do. Italian researchers found that volunteers who drank OJ had far less cellular damage from free radicals than another group who took the same amount of C in vitamin form.

If that weren't enough, citrus fruits may help you breathe easier. Oranges are rich in the antioxidant beta-cryptoxanthin (the pigment that gives them their brilliant hue). In studies, this compound has been shown to help ward off lung cancer, even in smokers.

HOW TO BUY THEM

Choose smaller, firmer, thinner-skinned oranges that feel heavy for their size. These tend to be the juiciest, sweetest fruit.

See a green patch? As long as the skin is smooth, it's nothing to worry about.

Once you have the fruit home, store them loose at room temp on your counter for about a week. Or put them in the fridge in plain sight. They'll keep there for up to two weeks.

WHICH ONES TO BUY

PUMMELO
Tastes like: A sweeter, less-tart version of its distant cousin, the grapefruit.
Cool fact: The largest of all citrus fruits, this green giant can sometimes grow big enough to masquerade as a watermelon.
Why you should try it: Pummelos are a great diet food, high in both water and fiber, that'll keep you feeling full as long as possible after eating.

MORO
Tastes like: A shot of OJ with a raspberry chaser.
Cool fact: Moros are nicknamed "blood oranges" because of their succulent deep-red pulp.
Why you should try it: To fight headaches and muscle pain. Moro oranges are filled with compounds called anthocyanins, potent plant pigments that protect your body from toxins and inflammation.

CLEMENTINE
Tastes like: A mixture of apricot nectar and canned mandarin oranges.
Cool fact: Clementines are the unwanted love child of an accidental tryst between an orange and a tangerine plant.
Why you should try it: Since they're small, seedless, and a cinch to peel and break into segments, Clementines are also the ultimate no-mess, portable fruit snack.

CARA CARA RED NAVEL
Tastes like: Fresh cherries with a tart cranberry zing.
Cool fact: The fruit gets its name from the flow-ers the Cara Cara tree produces—the tip of which resembles the human belly button.
Why you should try it: Cara Cara navels are the next best thing to a multivitamin, packed with the vitamin C you expect, plus cancer-fighting lycopene and vitamin A for healthy skin and Superman vision (minus the X-rays).

OROBLANCO
Tastes like: A grapefruit, only sweeter and without the harsh, bitter aftertaste.
Cool fact: There's no need for these oranges to ripen. The green skin means go—the fruit is ready to eat.
Why you should try it: To improve your workout. Oroblanco oranges are loaded with thiamin, which helps promote muscle growth, maintain a healthy nervous system, and keep stamina levels running at their peak.

MINNEOLA TANGELO
Tastes like: At once bold, sweet, and super tart—the Nicole Richie of citrus fruits.
Cool fact: Tangelos are easy to peel and highly noted for their knobby ends, further advancing the Nicole theory.
Why you should try it: To avert future heartache. One "mini" will nearly top off your body's folate reserves, helping to clear your system of an artery-clogging substance called homocysteine and dramatically reducing your risk of all forms of cardiovascular disease.
