Flu-Fighting Foods

Immunity-Boosting Foods
Food alone can't protect against the common cold or flu, and the science isn't yet clear on which nutrients may bolster immunity to reduce your risk of getting sick. But experts agree that a diet rich in a variety of produce, whole grains, lean proteins, and low-fat dairy products―along with adequate sleep, moderate exercise, and minimal stress―contributes to a well-functioning immune system and may promote a faster recovery if you do come down with a cold or flu. Here are some key nutrients and tips that will help increase the likelihood that you'll fly through the winter months in good health.
Eat for Health

“An overall healthful diet rich in vitamins and minerals is your best bet for the cold weather months,” says Julia Zumpano, RD, of the Cleveland Clinic Department of Preventive Cardiology. “You’ll also benefit from other nutrients not typically found in supplements when you eat a whole food.” Zumpano encourages plenty of fruits and vegetables (for vitamins C and E); whole grains, lean meats, and poultry (for zinc); and low-fat dairy products (for vitamin A). For example, in addition to vitamin E, a whole grain like quinoa or rye bread offers fiber, B vitamins, minerals, and other nutrients, which support overall good health.

Choose citrus, like grapefruit, oranges, kumquats, tangerines, and clementines as well as canned tomatoes, chiles, or pineapple for vitamin C.

Vitamin A

Pumpkin, butternut squash, and other deep-hued orange produce provide beta-carotene, which is converted in the body to vitamin A. The squash in this recipe is also packed with vitamin C, providing about half your daily needs per serving.
Zinc“Many studies have been done in nutrition and immune function involving numerous nutrients and come out with different, often contradicting results,” says Dayong Wu, PhD, a scientist in the Nutritional Immunology Laboratory, the USDA Human Nutrition Research Center on Aging, and Assistant Professor of the Friedman School of Nutrition and Science Policy at Tufts University. Because a nutritional intervention may have different effects on people of different ages or nutrition status as noted in scientific studies, Wu says, it’s difficult to make broad recommendations based on study findings.

However, zinc has been indentified with healthy immune systems, and it's a good idea to get enough of the mineral in your diet no matter what. One serving of this unique appetizer provides about 13 milligrams of zinc―that's all you need in a day.
The "Forgotten Nutrient"

Water is the largest single constituent of the human body―contributing to at least half your body weight―but it’s “also a forgotten nutrient,” says Jennifer K. Nelson, MS, RD, director of clinical dietetics at the Mayo Clinic in Rochester, Minnesota. This essential nutrient (meaning it’s one the body can’t produce on its own) promotes healthy muscle, bone, and blood. Adequate hydration is even more important once you’re sick because fluids lost through sneezing, watery eyes, and a runny nose need replacing. “When you have a mild fever, your body becomes more dehydrated as a result. So drinking plenty of fluids is probably the first line of defense,” Nelson says.

Water, coffee, tea, and juice, as well as water-filled foods such as fruit, vegetables, soups, and stews all count toward daily hydration needs.

One-Dish Nutrition

It's easy to combine foods to get many different nutrients in one meal. This dish brings together beef, a great source of zinc, with vitamin C-rich tomatoes. And great taste, of course.

Two Foods to Watch

Yogurt: The live active cultures in yogurt make it a probiotic, a source of good bacteria that may bolster the digestive system and improve regularity. Daily supplementation of probiotics during a three-month period shaved two days off common cold episodes and reduced the severity of symptoms, according to a German study of 479 participants published in journal Clinical Nutrition. The catch: No one knows exactly what dose―or which strains―of friendly bacteria work best for what conditions. But plain yogurt is a great way to gain calcium and potassium, both of which are linked with improved heart and bone health.

Green Tea: The catechins and other plant-based compounds in green tea may be linked to helping prevent colds and influenza. A study published in the Journal of the American College of Nutrition found that consuming green tea increased immune cells, boosting their ability to fight an affront to the system. In theory, that may translate to fewer colds and flu, says naturopathic physician Paul Anderson of Seattle’s Bastyr University. And if you get a cold, “it may be less severe,” he adds. The catch: “You’d need to drink at least eight to 10 cups a day of green tea,” Anderson says, to match the antioxidant amounts used in studies. If nothing else, green tea doesn’t seem to hurt, and a cup of hot tea contributes to your daily fluid needs.

    Mikroba Penyebab Kerusakan Jus Buah

    Umur simpan jus buah dipengaruhi oleh banyak faktor, mulai dari pemilihan bahan baku, cara pengolahan, peralatan dan mesin pengolahan, pengemasan, serta kondisi penyimpanan. Akan tetapi faktor utama kerusakan jus buah tak lepas dari adanya mikroba penyebab kerusakan. Kandungan zat gizi pada jus buah merupakan tempat hidup yang sesuai untuk pertumbuhan mikroba, selain itu didukung dengan kadar air yang tinggi dan nilai aktifias air (aw) yang juga tinggi (0,97-1,00). Jenis mikroba umum yang menjadi penyebab kerusakan jus buah yaitu dari golongan bakteri (misalnya E. coli, dan Klebsiella), kapang (misalnya Aspergillus sp.), dan khamir. Bakteri, kapang, dan khamir dapat menimbulkan aroma yang tidak sedap, toksin, gas, alkohol, busa, lendir, cemaran fisik, perubahan rasa, warna, bentuk dan kekentalan.   ...

    Cara Mencegah Chilling Injuries pada Buah

    Chilling injuries merupakan luka atau kerusakan yang disebabkan pendinginan sehingga menurunkan mutu buah. Kerusakan yang terjadi dapat berupa timbulnya bintik-bintik pada permukaan, pencokelatan, pelunakan tekstur dan pematangan yang tidak normal. Terjadinya chilling injuries tidak hanya disebabkan oleh besarnya suhu yang digunakan, namun juga lama paparan suhu tersebut terhadap produk. Beberapa buah tahan terhadap pendinginan dengan waktu yang pendek (Aked, 2002). Pada chilling injuries, jika buah atau sayur telah mengalami kerusakan maka akan lebih rentan mengalami kebusukan. Hal ini salah satunya karena kontaminasi bakteri Alternaria sp., yaitu mikrobia yang tidak tumbuh pada jaringan sehat, tetapi berkembang pada jaringan yang lemah akibat kerusakan suhu rendah. ...
