With headlines like “Dreaded ‘stomach flu’ wreaks havoc on families — and it’s only going to get worse”, the stomach flu is giving many families a rocky start to 2017. Stomach flu treatment focuses primarily on dealing with the symptoms while the virus runs its course, although a 2010 study suggests that probiotics taken early may shorten symptoms by about a day.

Vitamin C for Colds and Flu
Vitamin C has been demonstrated to have a strong anti-viral effect. Orthomolecular.org states: “In high doses, vitamin C neutralizes free radicals, helps kill viruses, and strengthens the body’s immune system. Taking supplemental vitamin C routinely helps prevent viral infections.” It has been shown to be effective against both the swine and bird flu.
The recommended dosage on Orthomolecular.org is as follows:
For best results, take vitamin C in evenly divided doses during the waking hours. Continue taking vitamin C on this schedule until, Pauling says, you have loose stool (just short of diarrhea). After having loosened stool, reduce the vitamin C dosage reduce by about 25 per cent. If you have another loose stool, reduce the vitamin C again, but if the symptoms of the viral infection begin to return, increase the dosage. You will quickly learn how much vitamin C to take; even children can learn to do this. Continue until you are completely well. Vitamin C greatly shortens the severity and duration of viral illnesses.
The recommended daily allowance of vitamin C for adults is 60 mg/day for adults, but research suggests that this a minimum to prevent deficiency diseases such as scurvy, not promote optimal health. The Linus Pauling Institute offers a comprehensive overview of optimal vitamin C intakes for different ages and conditions. Their basic recommendation is as follows:
For healthy men and women, the Linus Pauling Institute recommends a vitamin C intake of at least 400 mg daily. Consuming at least five servings (2½ cups) of fruits and vegetables daily provides about 200 mg of vitamin C. Most multivitamin supplements provide 60 mg of vitamin C. To make sure you meet the Institute’s recommendation, supplemental vitamin C in two separate 250-mg doses taken in the morning and evening is recommended.
What are the best food sources of vitamin C?
www.health.gov provides the following information on vitamin C content of common foods.
Vitamin D for Colds and Flu
Did you know cholesterol acts as a building block for vitamin D in our bodies? (Learn more about how cholesterol works in our bodies and why we need it.)
The World’s Healthiest Foods website explains:
Cholesterol is the basic building block of vitamin D in humans….when ultraviolet light hits the cells of our skin, one form of cholesterol found in our skin cells-called 7-dehydrocholesterol-can be converted into cholecalciferol, a form of vitamin D3.
The best source of vitamin D is sun exposure, which of course is often difficult to come by in winter. In lieu of sunlight, food and supplements are your next best option. The RDA for vitamin D from the National Institute of Health is as follows:
Table 2: Recommended Dietary Allowances (RDAs) for Vitamin D 
In 2010, the National Academy of Sciences set Tolerable Upper Intake Levels (ULs) for vitamin D as follows (source):
- infants, 0-6 months: 25 micrograms (1,000 IU) per day
- infants, 6-12 months: 38 micrograms (1,500 IU) per day
- 1-3 year old children: 63 micrograms (2,500 IU) per day
- 4-8 year year old children: 75 micrograms (3,000 IU)per day
- 9-18 years old children and adolescents: 100 micrograms (4,000 IU) per day
- adults, 19 years and older: 100 micrograms (4,000 IU) per day
- pregnant and lactating women, 100 micrograms (4,000 IU) per day.
As you can see, there’s a pretty big difference in those numbers, and some individuals with chronically low levels may need additional supplementation. Studies have linked low vitamin D levels to increased risk of cold and flu.
What are the Best Food Sources of Vitamin D?
The National Institute of Health lists some of the top foods for vitamin D:
Table 3: Selected Food Sources of Vitamin D 
** DV = Daily Value. DVs were developed by the U.S. Food and Drug Administration to help consumers compare the nutrient contents among products within the context of a total daily diet. The DV for vitamin D is currently set at 400 IU for adults and children age 4 and older. Food labels, however, are not required to list vitamin D content unless a food has been fortified with this nutrient. Foods providing 20% or more of the DV are considered to be high sources of a nutrient, but foods providing lower percentages of the DV also contribute to a healthful diet.
Personally, I wouldn’t touch the margarine, and am not too keen on the breakfast cereal. Mushrooms didn’t make their list, either, and they can be a good source of vitamin D. I’d prefer whole, raw milk, too. Vitamin D is a FAT SOLUBLE VITAMIN – which means your body can’t use it without fat.
Zinc for Colds and Flu
It has been shown that zinc lozenges or syrup taken early in the course of a cold can shorten its duration and severity. WebMD states:
First, zinc interferes with the ability of rhinoviruses, which are responsible for about 80% of all colds, to reproduce. Second, it appears to block their ability to dock on cell membranes and subsequently cause infection.
I generally recommend focusing on nutrient dense foods rather than supplements, but once in a while I make an exception.
If you would like to get your zinc from food sources, the top foods recommended by the National Institute of Health are as follows:
A wide variety of foods contain zinc (Table 2) . Oysters contain more zinc per serving than any other food, but red meat and poultry provide the majority of zinc in the American diet. Other good food sources include beans, nuts, certain types of seafood (such as crab and lobster), whole grains, fortified breakfast cereals, and dairy products [2,11].
Phytates—which are present in whole-grain breads, cereals, legumes, and other foods—bind zinc and inhibit its absorption [2,12,13]. Thus, the bioavailability of zinc from grains and plant foods is lower than that from animal foods, although many grain- and plant-based foods are still good sources of zinc .
Table 2: Selected Food Sources of Zinc 
* DV = Daily Value. DVs were developed by the U.S. Food and Drug Administration to help consumers compare the nutrient contents of products within the context of a total diet. The DV for zinc is 15 mg for adults and children age 4 and older. Food labels, however, are not required to list zinc content unless a food has been fortified with this nutrient. Foods providing 20% or more of the DV are considered to be high sources of a nutrient.
Good Nutrition is Your First Line of Defense Against Colds and Flu
If you eat a variety of real foods, including plenty of vegetables and fruits, fermented foods, bone broths and organ meats, you’ll be well on your way to getting what you need to help your body stay healthy. Regular exercise and time in the sun is also very important. If you’re going to use supplements, choose a reliable brand.

The best cold and flu remedies are the ones you add to your routine before you get sick. By including the right herbs, foods and probiotics in your regular routine, you’re less likely to get sick and more likely to recover faster if you do. I’ve made a habit of adding these herbs and spices for cold and flu fighting into our meals and herbal teas. This post discusses the best cold remedies (and flu remedies) using herbs, spices and your kitchen sink.
Do probiotics for colds and flu really help? Let’s check it out.
What are probiotics?
Probiotics are beneficial microorganisms similar to the “friendly” bacteria found naturally in the body’s digestive system. Howard Hughes Medical Institute (HHMI) of Maryland states that we each house two to five pounds (1.0 to 2.26 kilograms) of live bacteria inside our bodies. On average, we have 10 bacteria cells for each single human cell. We are more bacteria than we are human – strange, but true. (Makes using all those antibacterial products sound like a bad idea, doesn’t it?) [Read more…]Translate the Site
