Professional chefs understand how important food presentation is for the success of a meal. One element of the eating experience that can be under estimated however, is the effect of color. Scientific studies have shown that the color of the food and the eating environment effect appetite, often in a significant way. (more…)
What Is Metabolism?
From one of our readers: I’ve searched the web but found nothing that tells me how to
distinguish if my metabolism is healthy. I’ve found plenty of
ways to tell me how to improve my metabolism but nothing
that explains what is normal. Are there outward signs that
will tell you if your metabolism is healthy?
According to Webster’s Dictionary, metabolism is defined as a chemical and physical processes continuously going on in living organisms, But when most people think about metabolism they focus on one specific process , the process that releases and stores energy from the food we eat. This is because this type of metabolism not only affects how efficiently your body burns fuel but also influences how easily our bodies gain or lose weight.
Turning Food into Energy
In simple terms, your metabolism is the rate at which your body breaks down nutrients from the foods you eat and converts them into a form the body can use. After you’ve eaten a bowl of cereal or a sandwich, chemicals produced in the digestive tract, known as enzymes, break down all of the complex molecules that make up the food into smaller, more usable nutrients. Proteins are broken down into amino acids, fats into fatty acids, and carbohydrates into simple sugars like glucose. These nutrients are then absorbed into the blood where they are transported all over the body.
At this point the nutrients can be used in different processes. Amino acids are usually used to build and repair tissues, while glucose enters cells and is metabolized for energy. Any extra nutrients left over after these processes are generally stored in body tissues, especially the liver, muscles and body fat, and used for energy at a later date if the body needs it. (Think of it like a squirrel stocking up nuts for the winter.)
In this way, the process of metabolism really is a balancing act between two very different types of activities: (1) building up body tissues and energy stores, and (2) breaking down energy-rich nutrients, body tissues and energy stores to produce fuel that will power the body.
Anabolism, or constructive metabolism, focuses on building tissues and storing energy. During this process, small molecules are converted into larger, more complex molecules. For example, small molecules of glucose become larger, more complex storage molecules called glycogen. Amino acids are organized into proteins. And fatty acids are combined to create dreaded fat molecules. Anabolism is a very important process in the body, as it supports the growth and repair of cells and tissues and helps the body store energy so it can be used sometime in the future.
On the other hand, catabolism, or destructive metabolism, breaks down large molecules (mostly carbohydrates and fats) to release energy. We mostly refer to this energy burning as metabolism, even though this is not the only type of metabolism. This is the process that fuels all of the activity in our cells and keeps our body running. It also provides the energy needed for anabolic, energy-storing processes, helps heat the body and enables our muscles to contract so we can move.
The Importance of Hormones
Hormones are chemical substances in the body that control and regulate the activity of certain cells or organs, as well as specific chemical and physical processes. Several important hormones are involved in controlling the rate and direction of metabolism:………..

In some ways, your body is like a machine — it works best when itâ€™s properly maintained and tuned up. Food is your fuel and when you fill your tank with lousy fuel, your engine sputters and stalls. If your bodyâ€™s engine is sluggish and needs a jumpstart, spirulina and other green superfoods can help deliver the energy necessary to keep the machine running smoothly, avoiding a breakdown.
Spirulina is a â€˜green superfood,â€™ a term used to describe various nutrient-rich natural supplements, which include Chlorella, Wheat Grass, Barley Grass, Alfalfa and Kelp. Unlike most store-bought supplements, the concentrated vitamins and minerals they provide are not synthetic. Green superfoods are whole foods harvested directly from nature and are exactly what your body needs to offset stress and to clear away toxins.
SAD is very sad indeed
S.A.D. stands for Standard American Diet â€“ there was never a more apt acronym. The majority of U.S. citizens today subsist on processed fast food laden with refined carbohydrates and saturated fats. Meats are frequently tainted with growth hormones, antibiotics and pathogens. For people who manage to work the recommended five to nine daily servings of fruit and vegetables into their diet, modern agricultural techniques have stripped crops of many vitamins and minerals.
Processed and cooked foods, which are the cornerstones of the S.A.D, and beverages such as coffee, tea, soft drinks and alcohol create an acidic blood pH, encouraging the growth of bacteria, fungus and mold. In an overly acidic environment, the body literally begins to compost. Illnesses such as heart disease and diabetes are often the result of the composting process. Green superfoods have an alkalizing effect, counteracting the acidity caused by poor diet, stress and toxic overload and setting the stage for a return to good health.
Spirulina and Chlorella, the most super of the green superfoods
Spirulina is a blue-green algae whose name comes from its spiral coil shape. High quality spirulina thrives in both salt and fresh water in tropical climates and it is known to have nourished the Aztecs, who harvested the algae from Lake Texcoco. Some of the benefits of Spirulina are:
- Contains all of the essential amino acids vital to human health
- An excellent protein source for all vegetarians, including vegans
- Balances blood sugar by boosting glycogen, which offsets insulin
- Rich in GLA (gamma linolenic acid) and other essential fatty acids Delivers an array of vitamins, including the all-important folic acid
- High in potassium and a dozen other minerals
- Improves focus and mental clarity
Chlorella is a single-celled green algae whose name is derived from Greek and Latin words that translate to â€œlittle green.â€ In the 1940â€™s and 1950â€™s, intensive research was done on little green algaeâ€™s potential role in solving world hunger, due to its high protein content and its bounty of beneficial vitamins and minerals. The natural health community, meanwhile, has always touted Chlorellaâ€™s health-imparting properties, particularly in the area of detoxification. In addition to being the very best source of chlorophyll, here are some more of Chlorella supplement benefits:
- Rids the body of toxins and stored waste
- Tones and cleanses the blood
- Reduces body odor, acting as an internal deodorant
- Improves bowel health and reduces flatulence
- Naturally freshens the breath
- Clears the skin
Cereal grasses and seaweed
Wheat grass is a popular juicing ingredient due to its superior nutrition, which it delivers without raising blood sugar. It also helps to lower blood pressure.
Barley grass alkalizes the blood and strengthens the digestive system.
Alfalfa helps reduce LDL (low-density lipoprotein) or bad cholesterol, without affecting levels of HDL (high-density lipoprotein) or good cholesterol and studies are underway to determine its effectiveness at lowering blood sugar levels and its ability to invigorate the immune system.
Kelp is a brown-algae seaweed, which grows in abundant kelp forests in shallow oceans all around the world. Kelp is rich in iodine and therefore beneficial to overall thyroid health. Its high vitamin and mineral content promotes pituitary and adrenal gland health as well. Itâ€™s renowned for its contribution to lustrous hair and skin. Taken shortly after exposure, it can also mitigate the negative ramifications of heavy metals and irradiation.
Making the most of green superfoods
Incorporating Spirulina, Chlorella and other green superfoods into the diet is easy, since they are all available in powdered form. Simply mix the desired amount into salad dressing, or add it to soup, juice or water. The taste is fresh and green and the active enzymes of living food add a healthy dimension even to a less than healthy meal. Of course, pregnant or breastfeeding women and people taking medications should consult with their doctors before incorporating any new food into their diets.
Many people who regularly incorporate green superfoods into their daily regimen have reported increased energy, mental clarity and an overall healthy glow. When stress, toxic thoughts and an imperfect diet have left your bodyâ€™s engine sluggish, green superfoods are a quick and easy way to put yourself back on the road to health. Long may you run!

Here is what Louise has to say:
Give me five minutes and Iâ€™ll give you 1 very good reason for being vegetarian.
While fish is the most important dietary way to obtain the long-chain omega-3s eicosapentaenoic acid and docosahexaenoic acid, which has been shown to be essential in supporting brain health, low intake of eicosapentaenoic acid and docosahexaenoic acid in vegetarians does not adversely affect mood, reported by a new study (Nutr J. 2010;9:26. DOI:10.1186/1475-2891-9-26).
A research team from Arizona State University conducted a cross-sectional study to compare the mood of vegetarians who never eat fish with the mood of healthy omnivorous adults.
An overall total of 138 healthy Seventh Day Adventist adults residing in Arizona and California (64 vegetarians and 79 non-vegetarians) were enrolled in the study and completed a health history questionnaire, food frequency questionnaire and 2 psychometric tests, the Depression Anxiety Stress Scale and also the Profile of Mood States..
Vegetarians had significantly lower mean intakes of eicosapentaenoic acid, docosahexaenoic acid and the omega-6 arachidonic acid; they had higher intakes of the omega-3 alpha-linolenic acid and the omega-6 linoleic acid.
“Seed oils are the richest sources of Î±-linolenic acid, notably those of rapeseed (canola), soybeans, walnuts, flaxseed (Linseed oil), clary sage seeds, perilla, chia, and hemp.”
However, the vegetarians also reported significantly less negative emotion than omnivores in both psychometric tests. Mean total psychometric scores were positively linked to the mean intakes of eicosapentaenoic acid, docosahexaenoic acid and arachidonic acid , and inversely related to alpha-linolenic acid and linolenic acid intake.
The study team noted there is also the possibility that vegetarians may make better dietary choices and could generally be healthier and happier.
If you want to give it a try, here is an example of vegetarian recipe based on Italian cuisine
Italian Spaghetti with Zucchini
* 17 oz. Spaghetti
* 24 oz. Of thin sliced zucchini
* 1 / 2 cup walnuts oil
* A few basil leaves
* 2 tablespoons of yeast flakes
* Salt and pepper
In a skillet or frying pan heat the oil and when hot, add garlic and zucchini. Raise heat and stir often to complete their cooking. They need to be golden and crispy outside and tender inside. Cook the pasta, drain and sautÃ© in pan with zucchini, basil and yeast. Serve immediately.
Zucchini contain fewer calories and possess no fat. But they are a good source of potassium, e vitamin, ascorbic acid, folate, lutein and zeaxanthin.
These types of nutrients are extremely sensitive to heat and to enjoy their benefits you should find a quick solution to cook or even eat raw in salads.
From the therapeutic perspective, zucchini have laxative, refreshing, anti-inflammatory, diuretic and detoxifying action.

What exactly is a Nutrition Consultation? That is Question Number One from the public! Well, a nutrition consultation is something that takes into account someone’s medical and weight history; blood work/laboratory values; activity; habits; Calorie, protein, carbohydrate, fat and fluid needs; nutrition support needs and personal goals. A good nutrition assessment will take all of this into account in order to get a full picture of a client and what their specific needs and recommendations are.
A very common issue is that people think they are eating way too much at night and want to cut down on their intake a night. Most of the time, these folks aren’t eating enough during the day and find themselves so hungry at night that they make up for missed meals and more! In this case, I teach that food is the best appetite suppressant around! If you eat good, solid, healthy meals and snacks, you won’t feel so hungry later on in the night.
Of course, sometimes people experience “emotional eating” where they are counting on food to meet an emotional need that they have. At first it may feel like the need is fulfilled. Food is comforting, nurturing, it can seem like a “companion”. HOWEVER, food is fuel, not emotional support. When we mistake food for emotional support, we stop looking for the real, underlying emotional issues that need our attention. That is when food becomes a distraction, a past time, even an addiction. I urge clients to look at food as food and not an emotional crutch or distraction.
On the other end of the spectrum are the folks who need to gain weight and can’t seem to gain no matter what they do. A nutrition consultation will provide an assessment of exactly how many Calories they need to maintain and to gain weight. It will provide guidance for consuming healthy foods and not empty Calories, as well as recommendations for maintaining lean body mass.
Some folks need nutrition support, especially if they are on medications that deplete nutrients. My professional opinion is that the majority of people in this country do not even meet the RDA’s for many nutrients and I believe that the RDA’s need to be updated to reflect current knowledge and research in the science of nutrition.
A Nutrition Consultation will also help dispel the numerous misleading concept about nutrition that are out there floating around on the internet and in the media. I teach people some very basic concepts so that when they look at the latest headlines or listen to what other people have to say about nutrition, they will be armed with knowledge that will help them to judge what it truly best for themselves. So that is a Nutrition Consultation in a NUTshell.
And as always,
Consider having an individualized consultation!
