Fabulous Fungi

Mushrooms are not a true vegetable but a fungus. They have no roots or leaves, do not flower or bear seeds, and do not need light to grow. There are approximately 38,000 varieties of mushrooms, some edible and some highly toxic.

Their history is rich and revered. The Chinese used them for medicine. The Egyptian pharaohs declared them a food suitable only for royals. The French were the first to cultivate mushrooms in caves in the early 17th century. In the late 19th century, mushrooms were being grown commercially in both Europe and the United States. Farmers in Pennsylvania developed a method for growing mushrooms indoors, which is how most mushrooms are grown today. Many wild varieties are cultivated in this manner, which has allowed them to become more affordable and widely available.

The flavor of mushrooms comes from glutamic acid in part, which is a natural form of monosodium glutamate (MSG). MSG contains a considerable amount of sodium while fresh mushrooms are virtually sodium free.

Since they are not colorful, mushrooms had been thought of as lacking significant nutritional content, however, they do supply key nutrients. They are a decent source of the B vitamins niacin and riboflavin (they contain some B6 and folate too), iron, potassium, selenium, and vanadium (recently identified as an essential trace mineral in humans). They are a good source of dietary fiber. They contain the cholesterol-lowering soluble fiber beta glucan and they have also been discovered to contain antioxidant levels similar to other colorful vegetables. They are very low in calories with one cup of raw mushrooms supplying approximately 20 calories.

Mushrooms contain some vitamin D. When they are exposed to sunlight at the end of their growing cycle, they will produce a significant amount of vitamin D. They are one of the few foods to contain natural vitamin D. Look for the sunlight mushrooms in your local grocery store.

It used to be that the white button mushrooms were the only variety available in the marketplace. Now, varieties abound, cultivated and wild, fresh and dried. Mushrooms can transform the flavor of a dish adding an earthy rich flavor.

Mushrooms are highly absorbent and their contact with water should be limited when cleaning. With that said, they are 80% water and you will notice that they release water when being cooked. It is recommended that they be cleaned by wiping them with a damp towel or brush. Depending on what is being cooked, I often times will rinse them quickly in water to remove most of the dirt.

Herbs And Spices Pack More Than Flavor

Adding flavor to your food can be good for your health

When you think of herbal remedies, what comes to mind?  Is it black cohosh, ginko biloba, or echinacea?  Well, look no farther than your spice rack for the healing powers of these unassuming flavor enhancers.  Packed with phytochemicals, these leaves, stems and seeds may ward off a wide range of illness--from cancer to Alzheimer’s disease.  Read on to learn more.

Cinnamon

The bark of a tropical evergreen tree, cinnamon, is used to impart a sweet, spicy flavor to desserts and savory dishes.  An alternate role cinnamon may play is to inhibit bacterial growth, specifically Listeria monocytogenes, which is particularly dangerous for pregnant women, seniors, and those with compromised immune function.  Cinnamon steeped in hot water with tea may act to calm the stomach, lessening nausea and vomiting. Cinnamon may also play a role in blood-sugar regulation.  Of forty-nine herbs, spices, and medicinal plants tested by the US Department of Agriculture for their ability to regulate insulin, cinnamon ranked the highest.

Ginger

A twisted, knotted root common in Indian and Asian cooking, ginger may lessen pregnancy and chemotherapy-related nausea.  Recent research shows that ginger may also help to alleviate arthritis pain.  These findings, although promising, are relatively new and no recommendations are made for ginger to replace traditional osteoarthritis treatment.

Oregano

Oregano is a member of the mint family whose main components, thymol and carvacrol, are potent antioxidants capable of preventing lipid peroxidation and neutralizing food-borne bacteria, such as E. coli, Listeria monocytogenes, and salmonella.  Oregano exhibits stronger antioxidant power than vitamin E.  Other culinary herbs with strong antioxidant activity are rose geranium, sweet bay, dill, purple amaranth, and winter savory.

Rosemary

The use of rosemary in cooking dates back to 500 BC.  It has been used as a food preservative and as a cosmetic fragrance, as well as for medicinal purposes.  It is loaded with a variety of phytochemicals that are proving to be important in the realm of disease prevention.  It has been shown to be beneficial to heart patients, preventing low-density lipoprotein cholesterol oxidation, as well as helping to preserve memory by reducing inflammation and neuron damage.  Carnosol, one of rosemary’s chief constituents, may play a future role in the treatment of liver disease and leukemia.

Sage

The ancient Greeks and Romans used sage as a homeopathic remedy.  Spanish sage may have a future as a treatment for age-related cognitive decline.  It has been shown to mimic the action of certain anti-Alzheimer’s medications.

Thyme

Also a member of the mint family, thyme exhibits strong antioxidant and antimicrobial activity.  Its oils have been shown to disable respiratory pathogens, including those that cause influenza and pneumonia.  It may play a role in cognitive function as well.  Thymol, a primary phytochemical in thyme, may maintain optimal fatty acid balance in aging neurons.

Turmeric

Grown in India and other tropical areas of Asia, turmeric has antioxidant and anti-inflammatory properties owing to the phytochemical curcumin.  Two areas where turmeric’s effects are being shown are in the prevention of Alzheimer’s disease and certain forms of cancer, particularly those of the stomach and colon.

Despite the use of culinary herbs and spices in folk medicine for centuries, research into their ability to prevent disease is young.  They are best consumed in whole food form.  Individual plant chemicals isolated from the herbs may not have the same beneficial actions.  So add a little spice to your life, you may be healthier for it.

Nutritional Beauty

A healthy diet can make you beautiful inside and out

A growing consumer trend is to eat well for naturally glowing skin, strong shiny hair, and inner holistic radiance. We clearly are what we eat, and this mantra applies to more than just health.




Nutritional products have long been used topically to promote beauty. Honey masks, olive oil hair conditioning, and oatmeal baths can trace their roots back to ancient times. Retinol, a vitamin A derivative, and alpha-hydroxy have been shown to improve sun-damage or wrinkles when applied to the skin. Many cosmetics contain antioxidant vitamins, minerals, and plant chemicals. Most recently vitamin K has been discovered to lighten dark circles under the eyes.



The idea of promoting beauty can also be applied from the inside out. A top nutrient in this category is water. Without proper hydration, skin can seem dull and less supple. Antioxidant vitamins C and E, beta-carotene, and essential fatty acids are next in line. Antioxidants neutralize compounds that damage the body including skin. It is no lie that eating your fruits and vegetables can make you more beautiful. A recent study looking at the amount of vitamin C women consumed in their diet showed that those who ate the least amount of vitamin C from food had the most wrinkled appearance. Vitamin C is important for the synthesis of collagen, a protein that helps maintain skin elasticity. Fruits and vegetables are the main source of vitamin C. Another recent study showed that eating more carotenoid containing fruits and vegetables gave the skin a tanned hue when compared with study participants who did not eat the carotenoid containing foods. Carotenoids are the yellow to deep red pigments found in foods. You may say that eating fruits and vegetables provides skin a healthy glow.



The next big beauty secret believed by some estheticians is controlling inflammation from the inside out; not just reacting to a skin problem. Barry Sears, PhD president and founder of Zone Labs, Inc., contends that “inflammation links to all chronic disease, skin degeneration, and the aging process. To stop inflammation, balance protein and carbohydrate ratio at each meal.” Omega-3 fatty acids found in cold water fish such as salmon, walnuts, flax and chia seed exhibit anti-inflammatory properties. An increased intake of linoleic acid, and omega-6 fatty acid found in nuts, whole grains, most vegetable oils, eggs and poultry, is also associated with more youthful looking skin in research studies. Conversely, high intakes of saturated fat and refined carbohydrates abundant in the typical American diet are associated with a more wrinkled appearance.



Companies looking to capitalize on this trend are introducing products containing antioxidants, omega-3 fatty acids and phytochemicals. Will they make you more beautiful? Perhaps, if you already eat in a healthful manner, but drinking a special concoction won’t help if you are eating doughnuts for breakfast, sub sandwiches for lunch and pizza for dinner. And if you smoke, all bets are off. The aging effect of smoking undoes any good that a healthy diet or special supplement provides. Research shows that what matters more than eating a particular food or nutrient to prevent aging is to follow an overall healthy diet. People eat foods in combinations, not one at a time. It is the interplay of nutrients together that seems to provide the greatest anti-aging benefit. Here’s one more reason to eat your fruits, vegetables, whole grains, nuts and seeds. They can make you look marvelous.

The Cost of Inactivity

To stay healthy throughout life, you've got to move it! 

Very few things in life are static, especially the human body. From birth through old age, the body is continually changing. It is important to realize that when we put off regular exercise, our bodies are not just frozen in time, they’re fading. Physical activity stimulates most organs to work at their best. We are made to move, and if we don’t, all body systems are affected, right down to the cellular level, where our ability to transfer oxygen for energy can be diminished. This is evident in a person's inability to run between airline gates to catch a connecting flight, or carry laundry baskets up and down the stairs. Inactivity impacts the brain, muscles, heart, blood vessels, bones, liver, gut, sleep, anxiety, depression, self-esteem, and the ability to use glucose (to name a few).




Diabetes

Insulin sensitivity deteriorates with inactivity. Type 2 diabetes is characterized by the body’s inability to utilize the insulin it produces. The cells of the body become insulin resistant. Insulin carries sugar from the blood into the cells of the body. Without the ability to do this, blood sugar levels rise and diabetes develops.



Type 2 diabetes is a sedentary disease, in that regular exercise reverses the damage. Insulin sensitivity increases with exercise and the cells of the body become better at taking in and processing glucose. The impact of activity on diabetes is striking. Every two hours of weekly TV watching is linked to a 14% increase in the risk of diabetes. Conversely, every hour of brisk walking per week confers a 34% lower risk of developing diabetes. That’s something to think about the next time you are too tired or busy to put on your athletic shoes.



The Heart

Exercise affects the heart in several ways. Not only does it strengthen the pump, but it also impacts the pipes. In recent years, researchers have discovered that physical activity makes the lining of blood vessels more flexible, from the largest artery to the smallest capillaries. This allows blood vessels to relax, permitting more blood to be sent to the heart. Think of it in terms of pumping blood through a rubber hose instead of a concrete pipe. This is particularly important if a vessel is partially blocked.



Regular exercise also increases HDL (good) cholesterol. This is the type of cholesterol that leaves the arteries instead of sticking to them. For those who already have heart disease, exercise can lower your risk of dying from it. Take that to heart!



Stroke

Active people are 25% less likely to have a stroke than sedentary folks.

Exercise affects the arteries to the brain in the same way as the heart. Most strokes occur when a blood clot gets stuck in a partially blocked artery leading to the brain. Hemorrhagic stroke occurs when a blood vessel in the brain bursts. High blood pressure is a risk factor for any type of stroke, and regular aerobic exercise lowers blood pressure in 75% of people.



Muscles

If you don’t use it, you lose it. The metabolic cost of maintaining muscle is high. Muscles require a lot of energy, so if you don’t use them, they become a luxury for the body to maintain. As we age, we become increasingly inactive and lose muscle mass. Anyone can rebuild muscle with strength training. The earlier you start, the better, but even those of advanced age can benefit from carefully pumping a little iron. Strong muscles can help to prevent the frailty that makes older people lose their independence. Regular exercise is one way to stay out of a nursing home.



Weight

Inactivity and weight gain go hand in hand. When you lose your muscle mass because of inactivity, you need less energy (calories) to maintain what is left. Due to inactivity, it becomes possible to gain weight with a modest calorie intake, and nearly impossible to lose weight. The rate of weight gain is slow, perhaps 1-5 pounds a year, but over 10 years the pounds add up and the loss of physical fitness is significant.



In order to avoid becoming overweight or obese, 45-60 minutes a day of physical activity is needed. If you’re already overweight or have lost a lot of weight, you need more – between 60-90 minutes of physical activity a day to avoid regaining weight. If this seems daunting, just 30 minutes of exercise a day is enough to reduce the risk of many chronic diseases without significant weight loss.



Bones

Bones are living tissue. Every day, minerals move in and out of our bones in response to the demands of daily living. If you stress bone, it responds. If you don’t, the balance between bone gain and loss shifts toward bone loss. Research shows that strength training preserves bone better that walking or running, and can increase bone density. The amount that a bone is stressed, or overloaded, determines whether bone formation is stimulated. A small number of repetitions (8-15) with a heavy load can do the trick.



Regular physical activity has also been shown to prevent certain types of cancer, depression, dementia, and improve immunity. If exercise were a pill, it would be called a wonder drug.



To reduce health risks associated with inactivity, at least 30 minutes of moderate-intensity aerobic exercise five days a week or 20 minutes of vigorous aerobic exercise three days a week are required. To maintain lost weight, 60-90 minutes a day of exercise is needed. To build muscle and prevent bone loss, strength train at least twice a week with a weight heavy enough to lift eight to fifteen times.



The good news is that it is never too late to start moving. People well into their 90s can benefit from regular exercise. And if you’ve been moving all along, you can reach your 90s with vitality and independence. The only “magic bullet” out there that I know of is physical activity. So commit yourself to exercise. Schedule it in your date book. As a well known athletic company says, “Just do it!”

A World of Oats

Guest blog post by Laura Williams

Oats are a gluten-free cereal grain and are the third leading cereal crop produced in the United States (after wheat and corn) and the fourth most important crop worldwide. They were once considered a weed, but are now a popular staple of the British Isles like Scotland, Ireland and Wales. The grain was introduced into the Americas in 1602 by a sea captain who planted them in one of the islands off the coast of Massachusetts. Today, nearly half of the world's oat crop--more than 4 billion bushels a year--is grown in the United States and Canada. Oat kernels look very much like wheat in structure with an outer covering of bran, which protects the starchy endosperm and the germ that sits at the bottom of the grain. Whole grain oats contain seven B vitamins, vitamin E, and nine minerals, including iron, magnesium, selenium, manganese, phosphorous and calcium. Oats are very high in protein, containing about twice the protein of wheat or corn. But the most important nutritional advantages of oats are the soluble fiber and the GLA (gamma linoleic acid), an essential fatty acid. The soluble fiber is what gives oatmeal its gummy texture; it also has many beneficial effects on health. Regular use of oats in the diet can be helpful for managing several medical conditions. They have been shown to help control blood sugar levels, which is beneficial for people with both type 1 and 2 diabetes; to reduce cholesterol levels, which may help prevent heart disease; and to reduce plaque build up in the arteries which may help prevent atherosclerosis.



Different forms of oats:

• Oat groats: This is the whole oat grain, with only the outer hull removed. Oat groats are extremely nutritious, but they need to be soaked and cooked a long time. Oat groats are usually processed into one of the other forms below.

• Steel-cut oats: Produced by running groats through steel cutters, chopping the groats into smaller pieces and creating a chewy texture. Steel-cut oats still contain the whole grain and oat bran, and are also very nutritious.

• Rolled oats or old-fashioned oats: Steaming groats and then flattening them with a roller makes rolled oats.

• Quick-cooking oats: Steaming and flattening steel-cut oats makes quick-cooking oats.

• Instant oatmeal: Produced by rolling more thinly and steaming longer or partially cooking the oats. Instant oatmeal will also have salt, sugar, and in some cases artificial sweeteners added to it.



You can also grind rolled oats yourself to make oat flour.



Oats can be included in the diet in the form of oatmeal, cold cereals, baked products, granola bars, etc. Any way you include oats in your diet, you will still receive their beneficial effects.

Some recipes to try using oats include:



Muesli

Ingredients:

2 cups oats (quick or old fashioned, uncooked)

2 cups apple juice or apricot nectar

1-1/2 cups sliced fresh fruit (any combination of banana, peaches, nectarines or strawberries)

8 oz vanilla low-fat yogurt

2 T chopped nuts* (optional)

1 T ground flax seeds* (optional)



Preparation: Combine all ingredients except nuts and fruit; mix well.

Cover; refrigerate 8 hours or overnight.

Serve cold; add fruit and sprinkle with nuts, if desired. Refrigerate in airtight container up to 4 days

Oatmeal Raisin Cookies

Ingredients:

3 cups old fashioned oats

1 cup flour

½ tsp cinnamon

½ tsp baking soda

¼ tsp salt

1 cup honey or maple syrup

¾ cup softened butter

½ tsp vanilla

1 egg

½ cup raisins


Preparation: Preheat oven to 375 F. lightly coat cookie sheet with vegetable oil. Combine dry ingredients and mix well. Mix honey/syrup, butter, and vanilla until smooth. Add egg. Blend in dry ingredients, mixing thoroughly. Stir in raisins. Place rounded spoonfuls of blended ingredients onto cookie sheet and bake for 10 minutes. Makes 50 cookies.


I made three batches of these cookies each using a different sweetener (1 each with honey, maple syrup, and sugar) and would definitely recommend using maple syrup.

No Free Refills!

I'm often asked by people if they can eat all they want of a certain food. Perhaps vegetables or fruit? What about diet soda? You're not going to like what I have to say, but there are no free refills when it comes to healthy eating. In fact the notion of "free refills" perpetuates mindless eating. There is and should be a limit to what we consume. By eating all that we want, we tend to overeat (think about the last time you ate at a buffet). Shouldn't we stop and evaluate our level of hunger before eating more?

Hara hachi bu is an Okinawan expression that means eat until you are 80% full. This was traditionally practiced by the Okinawans who were among some of the longest lived people on the earth. Their diet consisted mostly of  vegetables, whole grains, fruits, legumes including soy foods, fish and very little amounts of meat. Sadly, younger generations of Okinawans may not live as long as their elders because they seem to prefer a more western diet, with a nice helping of western diseases to boot.

As a 15 year old athlete, my son has a healthy appetite. I'm fortunate that he likes most foods and with a dietitian for a mother, he gets more than his fair share of vegetables, whole grains and legumes. He often desires second or third helpings. I'll ask him if he's still hungry before digging in a second time. His reply has often been, "well, I'm not full." I don't believe that fullness should be the gauge that we have had enough to eat, but rather absence of hunger. Fullness is the gauge that we have overeaten. This is food for thought in a world of overabundance. It takes real discipline to practice hara hachi bu when we are being bombarded by food advertisements that make us want to eat more with excessive portion sizes on every street corner. A mere 100-200 hundred calories a day extra can prevent us from obtaining weight loss, and over time promote weight gain. It's something to think about when you want to eat more because something tastes good, but you are no longer hungry.

To those who question why we shouldn't eat as many vegetables as we want, after all they are low in calories; I say sure, eat plenty of vegetables. Most people don't eat enough. But no food should be eaten unchecked. A recent article in the New York Times told of an 88-year-old woman who developed life threatening hypothyroidism from eating two to three pounds of raw bok choy daily for several months. She believed that it would help control her diabetes. Instead it suppressed her thyroid. This is an extreme example, but it shows that you can get too much of a good thing.

My challenge to you, try practicing hara hachi bu for a week. Be mindful about the food that you eat and stop eating when you are no longer hungry, but not full.

Diets Don’t Work? …Really?

Have you ever noticed how an idea gains popularity but the idea may not be true? Drinking eight cups of water a day is one such concept. It seems like a good idea, but there are many people who do fine drinking less and many people who need more. Another such idea is that diets don’t work. This is a common idea circulating within the nutrition community and one that I’m sure many “dieters” have also heard. The purpose of this idea is to move people away from the “dieting” mentality to encourage them to engage in healthy eating and lifestyle habits, and to become more aware of their bodily need for food. It also, unwittingly lays blame with the “diet promoting” community for the failure of dieting efforts.




As a practicing dietitian for 20 years I have to say that diets DO work! I’ve been witness to many people achieving their goals by following a specific dietary plan. The problem is that people can be limited by their ability to follow recommendations consistently. There are all sorts of reasons for this, too numerous to describe, but here are a few: emotional eating related to the need for comfort, lack of time to prepare meals due to social pressures, and medical problems (and medications) that change the body’s response to food.



Perhaps the first myth to dispel is that "diet" is a four letter word. It depends on how you look at it. The word “diet” as a noun describes a way of eating. All living creatures have a diet, ranging from the worms and bugs that birds eat to the broad variety of items my dogs eat – dog food supplemented with small rocks, twigs, shoes, undergarments and broccoli. Change diet into “dieting” and viola—it becomes a verb. This is how many of us are most familiar with the word. Dieting implies that we are doing something to change our eating regimen—not necessarily a bad idea. But when one “goes on a diet” they inevitable must “go off a diet” abandoning all the good changes that they previously made. It seems best to focus on the word diet as a noun to grasp the long term nature of what our commitment should be to a healthy diet. As long as we are living and eating, our commitment shouldn’t end.



Research conducted by the National Weight Control Registry showed that people can lose weight on ANY diet plan. So weight loss doesn’t seem to be the problem as much as weight maintenance. And weight is not maintained when the permanence of an eating regimen is not considered. As is the case with weight loss, there are many diets that are successful in improving other aspects of health. The Mediterranean diet is heart-healthy. The DASH diet lowers blood pressure, and has recently been shown to help prevent kidney stones. And there are many different diet manipulations that can improve intestinal function, reduce the risk of cancer, lower cholesterol levels and control blood sugar. Diets do work!



I agree with my colleagues who espouse the non-dieting approach, but don’t say that diets don’t work. Let’s go back to looking at the word “diet” as a noun and encourage each individual to choose the best diet to achieve and maintain their health.
