Functional Foods

Functional foods are foods with health-promoting benefits and/or disease-preventing properties that go beyond its fundamental nutritional value. Functional foods can be found in any supermarket and understanding what these types of foods do for us can be very beneficial.

Understanding Functional Foods

These foods are categorized as having pre-biotic and pro-biotic bacteria and are found in some types of yogurt and fermented milk products. Pro-biotic bacteria is a ‘live microbial feed supplement that beneficially affects the host animal by improving its intestinal balance.’ This means that pro-biotics improve the balance of bacteria in the gut, which reduces the risk of disease. Conversely, pre-biotic foods aren’t digested by the body but stimulates the growth of certain bacteria in the colon, causing improved health. Pre-biotics include ingredients such as inulin or fructo-oligosaccharides (complex carbohydrates which are added to certain yogurts). Other functional foods are enriched with plant chemicals, which can be found in margarines such as Benecol and Flora Proactive. Plant chemicals are similar in structure to cholesterol and are called sterols. They differ from cholesterol in that they are not absorbed by the gut and can inhibit the absorption of cholesterol from the diet. Studies have shown that plant sterols can significantly reduce LDL-cholesterol (bad cholesterol) while raising HDL-cholesterol (good cholesterol) in the blood. Other functional foods are fortified with folic acid, which are found in staple foods such as bread or breakfast cereals. A good intake of folic acid or folate (B vitamin) is needed to reduce the risk of neural-tube defects, such as spina bifida that can develop in unborn babies. Finally, there are functional foods that are fortified with n-3 or omega-3 fatty acids that are found in foods like eggs. People who have high intakes of oily fish, which are a strong source of omega-3 fatty acid have a lower incidence of heart disease than those who don’t. By incorporating beneficial fish oils into products such as eggs, people who dislike oily fish can still benefit from these oils.

“Staple foods” was mentioned above and a basic definition is added here. They are a basic but nutritious food that forms the basis of a traditional diet, particularly that of the poor. Although nutritious, staple foods generally do not by themselves provide a full range of nutrients, so other foods need to be added to the diet to prevent malnutrition. Staple foods vary from place to place, but are usually of vegetable origin, from cereals, pulses, corn, rice, millets and plants growing starchy roots. Bread, noodles (or pasta), rice congee, polenta and porridge are prepared from them. Types of bread that are considered staples in some parts of the world are tortillas, chapatis, naan, and mantou. Staple crops harvested as root vegetables for their starchy underground storage organ include cassava, potato, sweet potato, yam, and taro.

The Benefits of Fiber!

We all know the benefits of fiber! Fiber not only promotes health, it also help reduce the risk for some chronic diseases. Both soluble and insoluble fiber are undigested. They are therefore not absorbed into the bloodstream. Instead of being used for energy, fiber is excreted from our bodies. Soluble fiber forms a gel when mixed with liquid, while insoluble fiber does not. Insoluble fiber passes through our intestines largely intact.

Fiber

Dietary fibers are the indigestible portion of plant foods that move food through the digestive system and absorb water. There are two principal types of dietary fiber: soluble and insoluble. Insoluble fiber is simply bulk that changes little as it passes through the body. Soluble fiber, on the other hand, forms a soft gel in solution with water. Most foods provide a mixture of both, but are listed as mostly one or the other. Soluble fiber has been shown to be able to bind bile salts which may reduce blood cholesterol levels. It also may slow the absorption of glucose from the intestine, thereby requiring less insulin secretion.

Fiber may decrease spasms in the gastrointestinal tract by keeping the lumen distended. The main value of dietary fiber is that it provides bulk to the bolus moving through the digestive tract. There are two great advantages to this: by bulking up the bolus, eventually increasing the weight of the stool, it’s easier for the digestive system to move it through, and the bulkier stool also tends to retain normal amounts of moisture to make it easier to eliminate with less straining and abrasion. The moisture content of human stool does not change when more fiber is consumed, except marginally from psyllium husk (Eastwood et. al & Prynne et. al). Because the bowel regulation is mostly due to bulking and not to increased water in the stool, it is very unlikely to cause diarrhea unless taken in massive amounts (this is as long as one does not consider synthetic sugars in this category).

Increased fiber consumption appears to lower the risk of developing type II diabetes, heart disease, and diverticulitis. [1] It may also help prevent high cholesterol and help fight obesity. High-fiber foods help move waste through the digestive tract faster and easier, so possibly harmful substances do not have as much contact with the gastrointestinal tract and reduce straining. Many cause blood sugar or cholesterol absorption to decrease in amplitude of the plotted absorption or decrease the amount absorbed by slowing or decreasing the absorption. Although for years dietary fiber has been said to reduce the risk of colon cancer, one study conducted by researchers at the Harvard School of Medicine of over 88,000 women did not show a statistically significant relationship between higher fiber consumption and lower rates of colorectal cancer or adenomas. Negative effects of dietary fiber include a reduced absorption of vitamins, minerals, proteins, and calories from the gut. Some insoluble fibers can bind to certain minerals: calcium, magnesium, phosphorus, and iron. This is unlikely to be harmful in the average adult, but guidelines for the US have been established, and fiber users are advised to avoid taking an insoluble fiber supplement at the same time as, or soon before or after, taking vitamin or mineral supplements.

Sources of Fiber:

Current recommendations suggest that adults consume 20-35 grams of dietary fiber per day, but the average American’s daily intake of dietary fiber is only 14-15 grams. [3] The ADA recommends trying to get most of your dietary fiber from foods you eat, as an important part of consuming variety, nutrition, synergy between nutrients, and possibly phytonutrients. Soluble fiber is found in many foods, including:

* legumes, (peas, soybeans, and other beans)
* oats
* some fruits (particularly apples, bananas), and berries
* certain vegetables, such as broccoli and carrots
* root vegetables, such as potatoes and yams (the skins are insoluble fiber)
* psyllium seed (only about 2/3 soluble fiber).
*Legumes also typically contain shorter-chain carbohydrates that are indigestible by the human digestive tract but which are digested by bacteria in the small intestine, which is a cause of flatulence.
Sources of insoluble fiber include
* whole grain foods
* bran
* nuts and seeds
* vegetables such as green beans, cauliflower, zucchini, celery
* the skins of some fruits, including tomatoes

Basic Food & Health Tips!

I said in last month’s newsletter, that we don’t need to get complicated when we strive to excel with our health. I discussed what I thought was valuable regarding a workout routine and suggested a very simple food program as a suggestion towards creating new habits with food that will have long-term affects to your physical health. We’ll be discussing medicinal qualities of food and food in general for the next several newsletter.

The more knowledge we can learn about food and how it affects our body the more we can be engaged with our physical self. Again, rather than hiring someone to do it for us, it is better to engage in the process for ourselves and have someone assist us in that process. It is very difficult to maintain consistency when we have the perspective that I’ll hire someone to get me to my goal. We are the only ones who can get us anywhere! And with this perspective, we are able to tap into our passions and generate motivation and fulfillment for ourselves.

Food Tips

Alcohol

In chemistry, alcohol is any organic compound in which a hydroxyl group (-OH) is bound to a carbon atom, which in turn is bound to other hydrogen and/or carbon atoms. The general formula for a simple acyclic alcohol is CnH2n+1OH. In general usage, alcohol refers almost always to ethanol, also known as grain alcohol, and often to any beverage that contains ethanol (see alcoholic beverage). This sense underlies the term alcoholism (addiction to alcohol). As a drug, ethanol is known to have a depressing effect that decreases the responses of the central nervous system (see effects of alcohol on the body). Other forms of alcohol are usually described with a clarifying adjective, as in isopropyl alcohol or by the suffix -ol, as in isopropanol.

This substance, in and of itself, is tasteless and colorless. “Congeners” that are included in alcohol to give it color, flavor, and character. These “congeners” stem from the aging of the liquor to its fermentation. The bacteria in our bodies actually produce tiny amounts of alcohol all the time. When alcohol enters the stomach, it reacts with an enzyme in the stomach and liver that transforms the alcohol to acetaldehyde. It is the acetaldehydes that we should be concerned about because they are the producers of our nasty hangovers. Alcohol just get’s us drunk. The body burns off about half an ounce of pure alcohol (about the amount in a dose of alcohol) in an hour. Let’s demonstrate this point with your average 12 ounce can of beer. A 12 ounce can of beer is about 5% alcohol and so only has about a half ounce of alcohol in it. A 5 ounce glass of wine is 12% alcohol and a one & a half ounce shot of 80 proof whiskey is about 40% alcohol. Do the math and you’ll find out how long it takes you to burn off the alcohol that you consume. Once the alcohol reaches our bloodstream, it travels to various parts of the body. Once it enters the brain, it replaces the water molecules of the brain and so slows down the its efficiency. Also, overdoses of alcohol shuts down our central nervous system, which in extreme cases causes the brain to stop sending us signals that remind us to breathe. All alcoholic drinks have a lot of calories with very little protein.

Caffeine

Caffeine, sometimes called theine when found in tea, is a xanthine alkaloid found in the leaves and beans of the coffee tree, in tea, yerba mate, guarana berries, and in small quantities in cocoa, the kola nut and the Yaupon holly. In plants, caffeine acts as a natural pesticide that paralyzes and kills many insects feeding upon them. Caffeine is a central nervous system (CNS) stimulant, having the effect of warding off drowsiness and restoring alertness. Caffeine-containing beverages, such as coffee and tea, enjoy great popularity, making caffeine the world’s most popular psychoactive substance.

The world’s most popular drink is coffee and the “boost” it contains can be found in 60 types of plants. Coffee, tea and cocoa are just the most popular of the bunch. Many health problems are associated with Caffeine ranging from addiction, heart disease, and low birth rates in babies. These risks are more likely to happen to people who drink 5 or more cups per day. It also stimulates the central nervous system by affecting chemical carriers in the brain that are known as neurotransmitters. Thus, it can make you feel more attentive and can increase your capacity to concentrate. This results in the feeling of alertness that is associated with Caffeine, as well as causing your metabolism to speed up to allow for the burning of calories. That does not mean that Caffeine helps you lose weight! It doesn’t because the increase in your metabolism is very small. The maximum amount of coffee that a person should drink per day is four cups, because any more than that can cause an increase in your cholesterol and blood pressure. Other studies link caffeine to breast cancer and miscarriages.

Sugar

In general use, “sugar” is taken to mean sucrose, also called “table sugar” or saccharose, a disaccharide which is a white crystalline solid. It is the most commonly used sugar for altering the flavor and properties (such as mouthfeel, preservation, and texture) of beverages and food. Table sugar is commercially extracted from either sugar cane or sugar beet. The word sugar originates from the Sanskrit word sharkara, which means “sugar” or “pebble.” The “simple” sugars, or monosaccharides, such as glucose, are a store of energy which is used by biological cells. A sugar is denoted by any word on the ingredient list that ends with “ose”. Given that sugar contributes energy (calories), if you consume more than you need you will gain weight. Weight gain increases your risk of getting heart disease, diabetes, high blood pressure or even some types of cancer. However, if you are underweight, sugar can add extra calories so that you can gain weight. If your body doesn’t make enough insulin (in case of diabetes), then the sugar you eat increases the sugar in your blood to unhealthy levels. The body breaks down sugar into the simple sugar that is found in your blood (glucose). Unfortunately, there are no vitamins or minerals in sugar and so it is called an “empty” nutrient. That is why it is the first food to be eliminated from a weight loss diet. By the way, it does not matter if the sugar is white or brown. The amount of molasses in brown sugar is so low it doesn’t contribute enough of any vitamin or mineral to count.

Sugar Substitutes

• Zsweet: a natural diet sweetener made from erythritol, a granular sugar alcohol approved for use in the United States as a food additive and sweetener.
While erythritol is 70 percent as sweet as table sugar, it is substantially less caloric and has a mild cooling effect in the mouth. Zsweet can be used for baking.
• Sucralose: a noncaloric sweetener also known by the brand name Splenda.
It is about 600 times sweeter than sugar and is the only artificial sweetener on the market made from sugar. It is altered artificially with chlorine atoms. Heating doesn’t reduce its sweetening power, so it can be used in baking.
• Aspartame: sold under the brand names Equal and NutraSweet and approved for use in hundreds of foods and beverages.
Aspartame is made from two amino acids: phenylalanine and aspartic acid. It is not good for baking and is about 220 times sweeter than sugar.
• Stevia: a natural, zero-calorie sugar substitute found in health food stores.
It is made from a South American shrub and is about 300 times sweeter than sugar. Unlike Zsweet, approved by the FDA as a food, Stevia is sold as a dietary supplement in the U.S. It does not measure like sugar and is not ideal for baking.
