The familiar chill of fall reminds us that we’re seeing less of the sun.  Less sunlight means fewer opportunities to maintain adequate levels of vitamin D in our bodies.   With all the buzz surrounding calcium, the importance of vitamin D in supporting strong teeth and bones was long overlooked.  So let’s spend a few minutes getting up to speed on calcium’s biggest supporter, vitamin D. 

Vitamin D is a fat-soluble vitamin that is naturally present in few foods, fortified in few others, and available as a dietary supplement.  Additionally, our bodies can synthesize vitamin D with adequate sun exposure. The process begins with the inactive form of vitamin D in our skin.  When met with sufficient sunlight, the hormone is converted into an active form of vitamin D through a process in our kidneys and liver.  Active vitamin D allows our bodies to better utilize calcium, meanwhile playing an important role in maintaining muscle.  Thus, vitamin D has been credited with the prevention of falls and subsequent fractures in aging populations.

Groups at higher risk of vitamin D deficiency include older adults, people with limited sun exposure (which would include most Americans in the winter months), people with dark skin, obese individuals, and breastfed infants.  So how much do you need?  The jury is still out on this one.  Current recommendations suggest the following daily intake:

- Age 50 and under:  200 International Units (IU) or 5 micrograms (mcg)
- 51-70:  400 IU (10 mcg)
- 71 and older:  600 IU (15 mcg)

That said, research suggests these intakes are too low, with some researchers estimating as high as 1000 IU per day.  In other words, it’s best to think of the current recommendations as minimums. 

Below is a list of food sources of vitamin D.  As you can see, foods that naturally contain vitamin D aren’t common in the American diet, and those that are fortified with vitamin D (most notable being milk) are not very rich sources. So unless you typically consume a tablespoon of cod liver oil daily, or drink upwards of 48 ounces of milk, it’s best to leave it to supplementation.

TOMATOES

Summer dish: Sliced tomato with balsamic vinegar
Nothing says summer like vine ripe tomatoes. Tomatoes naturally lend themselves to health-conscious summer cooking, being sweet, yet low in calories. In fact, tomatoes are one of the most frequently consumed “vegetables” in the United States, whether raw, steamed, fried, stewed, crushed, pureed, or reduced to a sauce. (Though thought of as a vegetable, tomatoes are botanically classified as fruits.) They are also one of our best sources of vitamin C, a powerful antioxidant.

They also contain beta-carotene and several other carotenoids that may have their own disease-preventing properties, particularly against heart disease and cancer. One carotenoid, lycopene, may help reduce the risk of prostate cancer. Tomatoes also offer a good dose of potassium, which helps to reduce the risk of stroke.

SALMON

Summer dish: Simply grilled on the barbeque
Summer marks the beginning of salmon fishing season and the time of year when fresh salmon is again available in your local markets. Salmon is low in calories and saturated fats and high in protein. Wild salmon is one of the best sources of health-promoting fats known as the omega-3 fatty acids. Omega-3s promote cardiovascular health, brain health and provide anti-inflammatory protection.

Cardiovascular health: omega-3’s prevent platelets in the blood from clumping together and sticking to the arterial wall in the form of plaque. They also drive down triglycerides and LDL (bad) cholesterol.

Brain health: Omega-3’s interact with the fatty layers that surround brain cells and help protect brain cells from the diseases of aging, like Alzheimer’s.

CORN

Summer Dish: Corn on the cob
Is there anything more satisfying at a summer bar-b-que than an ear of hot corn on the cob? In addition to being sweet and satisfying, there are many health benefits of corn.

One cup of corn provides 18.4 percent of the daily recommendation of fiber. Its high-fiber content is one of the biggest benefits of corn. Fiber has been shown to help lower cholesterol levels and help reduce the risk of colon cancer. Fiber is also useful in helping to lower blood sugar levels in diabetics.

Corn is a surprising source of several vitamins, including folic acid, niacin and vitamin C. The folic acid in corn is now known to be an important factor in preventing neural-tube birth defects. It’s just as important in preventing heart disease, according to studies that show folic acid can prevent a buildup of homocysteine, an amino acid in the body.

SUMMER SQUASH

Summer Dish: Sautéed or grilled squash
Summer squash contains vitamin C as well as beta-carotene, folate and fiber. These nutrients make summer squash a tool in preventing cancers, heart disease and diseases caused by inflammation such as arthritis and asthma.

Whether you’re trying to lose weight or just adopt a healthier eating program, summer squash’s rich fiber content can help you get full faster — and give you many of the nutrients you need.

Q: Is canned salmon, just as nutritious as the fresh kind?

A: On the downside, canned salmon contains more than six times as much sodium — 399 milligrams per 100 grams (about 3.5 ounces) as fresh salmon. Regrettably, some of the heart-healthy omega-3 fatty acids that salmon is praised for get lost in the canning process, so canned salmon has only about half the total amount of the two most important omega-3s EPA and DHA.

However, canned salmon contains many additional beneficial nutrients, not found in their fresh counterparts. The differences develop from how canned fish is processed, and from the fact that bones are included. One 3.5 ounce serving with bones contains two thirds as much calcium as a cup of milk, making this product one of the most calcium-rich, non-dairy foods. Canned salmon also has more vitamin D and phosphorus per serving than fresh salmon. Both canned and fresh salmon give you roughly the same amount of protein, 22-23 grams per 100 grams.
The American Heart Association recommends eating fish 3 times a week to reduce the risk for cardiovascular disease. Despite the fact that you’ll need to eat it more frequently to get enough omega-3s canned salmon can be a delicious and nutritious part of any diet. In addition, canned salmon costs less per serving than fresh, and canned products are an economically wise choice because they have a long shelf life.

In the past few years, omega-3 fatty acids have become increasingly popular with their numerous amounts of health benefits. Omega-3 fatty acids work as an anti-inflammatory agent that helps reverse the processes of heart disease, cancer and many other conditions.  As of Monday, April 13th, new research has just been added to the American Journal of Clinical Nutrition on the effects of walnuts and fish on heart disease.

Researchers from Loma Linda University concluded that in healthy individuals walnuts lowered cholesterol more than fish, while fatty fish lowered triglyceride levels ultimately both reducing the overall risk of coronary heart disease. This study was conducted to show everyone including the healthiest of people how imperative and easy it is to simply add walnuts and fatty fish to their daily diet.

The American heart association recommends eating fish 3 times a week to reduce the risk for cardiovascular disease. Using this as a guideline, the researchers found that healthy people who included fatty fish twice a week, decreased triglyceride levels by 11.4 percent. In addition, adding 1.5 ounces of walnuts to their eating regimen lowered their LDL levels by 9.3 percent compared to a control diet based on USDA recommendations. Studies have shown that walnuts can significantly reduce blood cholesterol. Walnuts are rich in polyunsaturated fatty acids, and they also help keep blood vessels healthy and elastic.

Some of the highest levels of omega-3 fats can be found fish like mackerel, lake trout, herring, sardines, albacore tuna, and salmon.  The reason for this being, that fish is a good source of protein and doesn’t have the high saturated fat like ones found in fatty meats.

Sushi bars are the fastest-growing restaurant segment of the ethnic food industry. That’s good news for Americans, because if you’re in search of a healthy meal, Japanese food fits the bill. Traditional Japanese food is one of the healthiest fares, most often prepared with little oil and features ingredients like tofu, rice, seaweed, noodles, vegetables, and small quantities of fish, chicken, and lean meat. Most sauces are low-fat, and made with a base of broth, soy sauce, or sake. But beware! As sushi becomes more and more mainstream, many rolls are being created to suit the high-fat palette of American diners. Nowadays, cream cheese, tempura flakes, mayonnaise, and deep-fried fish, are popular ingredients in sushi rolls.

With these recent additions, it has become quite easy to walk out having consumed 1,000 calories without even realizing it. Below are some ways you can enjoy eating out at your favorite Japanese restaurant while sticking to The F-Factor Diet.

Here are some of my tips:

1. Start with a soup and salad.  Beginning your meal with a miso soup (50 calories) and a house salad with ginger dressing (110 calories), or seaweed salad (110 calories) fills you up and prevents over eating during the main course. Even if you’re not necessarily in the mood, trust us and order it! While edamame can be a healthy snack, the calories quickly add up; a 4 oz serving provides 170 calories and 6 grams of fat.

2. Roll it with cucumber.  A typical roll of sushi is prepared with one cup of rice (3 servings of carbs) to coat the seaweed. This one cup of rice provides 240 calories, and that’s before anything else is even added. Ask for your roll to be wrapped in cucumber instead of rice to save hundreds of calories.

3. Limit the rice.  If you are craving rice with your sushi, be assertive and request “light rice” (less rice). Take it a step further and request brown rice, when possible, for an extra-fiber boost. If you’re ordering two rolls, get one with rice and the second roll wrapped in cucumber.

4. Keep it simple.  Avoid battered and fried ingredients, including anything “tempura” or “crunchy.” Tempura is not only battered, but deep-fried as well. One shrimp tempura roll contains 544 calories and 13 grams of fat! Also, avoid the mayo typically found in “spicy” versions of common rolls like tuna, spicy salmon, etc. Each tablespoon of spicy mayo packs an additional 100 calories and 11 grams of fat into the roll.

5. Order sashimi.  Sashimi is low in calories, high in lean protein, and contains zero servings of carbohydrates. A one-ounce piece of tuna sashimi contains only 35 calories while a one-ounce piece of salmon sashimi contains only 55 calories. Aside from being low in calories, you also get the benefits of omega-3 essential fatty acids.

6. Healthier options.  Look for broiled, grilled or steamed items. Some examples of healthy options are sunomono (various seafood in vinegar sauce), tuna tataki, carpaccio and oshitashi (steamed spinach with soy sauce).

7. Ask for low-sodium soy sauce.  While salt contains zero calories, too much can increase blood pressure and can leave you feeling bloated. To counteract the sodium, make sure to wash your meal down with plenty of water.

Of the nearly two thirds of U.S. adults surveyed, 64 percent agree that they are filled with greater joy soaking up the summer sun, then bundling up in winter coats. According to studies done at Cornell University, the winter blues and its more severe foil, Seasonal Affective Disorder (SAD), affects about four times as many women as men.

Although the science is still relatively new, research has begun to reveal how mindful eaters can choose their fuel to help achieve or maintain a desired mental state.  Our moods are linked to the production or use of certain brain chemicals. Scientists have identified many of the natural chemicals in foods that change the way we feel. Food influences neurotransmitters by attaching to brain cells and changing the way they behave. This opens pathways to those cells so that other mood-altering chemicals can come through the gates and attach themselves to brain cells.

So the next time you want to change your mood, take a walk to the kitchen — it might just save you a trip to the therapist!

To ease feelings of depression:  Eat more fish!  Omega-3 fatty acids (found in fatty fish such as salmon, herring, sardines and tuna) may help ease depressive symptoms.  A recent study showed that eating fish twice a week was associated with lower risk of depression and suicide. Magnesium, can also ease symptoms of depression. Enjoying a bowl of whole-grain cereal and soy milk topped with walnuts will supply you with magnesium and increase your intake of omega-3 fatty acids, which will ease your frame of mind into the afternoon frenzy when your kids come home.

To get out of a bad mood: A lack of selenium can cause bad moods. Individuals suffering from too little selenium have been shown to be more anxious, irritable, hostile and depressed than people with normal levels of selenium. Pistachios, salmon, and shitake mushrooms can instantaneously get you out of this funk.

When you want to feel pleasant and alert: Eating foods that stimulate the release of dopamine may produce enjoyable feelings. Phenylnine is an essential amino acid found in the brain and blood that can convert in the body to tyrosine, which in turn is used to synthesize dopamine instantly increasing your energy and alertness. Start your morning off with a bowl of hot oatmeal to warm you up try adding skim milk and sliced bananas to add a boost of dopamine and to leave you feeling happy throughout the day. Breakfast is a must because it provides glucose to your brain, making you mentally efficient and vigilant.

When you want to feel happy:  When we don’t get enough exposure to sunlight our moods and physical health may suffer. More specifically, serotonin levels, a hormone associated with elevating your mood rises when you’re exposed to sunlight. So we often feel sad during the darker, winter months.  An amino acid, tryptophan helps raise serotonin levels in your body, causing you to feel upbeat once again. Eating foods that are high in tryptophan such as, simple carbs, low-fat cottage cheese, nuts, and chicken will help cure your winter blues.  A slice of whole-wheat toast with low-fat cottage cheese and jam is a sure way to boost your mood. 

Get Moving: Studies show that anywhere from 30 minutes to an hour of exercise every day can have a positive impact on your mood. When we exercise our body releases endorphins that help us to feel happy, but it also has been shown to reduce stress, which often intensifies feelings of depression brought on by the winter blues.  It can also increase your joy by making your skinny jeans and little black dress fit better, and is there any greater feeling then that?!
