Nutrition, Evolution, and Having a Healthy Diet
Judith Schwader

Nutrition has everything to do with health. This isnt news, exactly, but looking around at the crazy information on the market, one wonders if anyone actually makes the connection: what you eat affects how you feel. Its that simple. Your health depends on the food choices you make in both the short and long term.

Take a pill, and all youve done is treat a symptom. Change your eating habits, and create a lasting change in your well-being. There are so many approaches to eating, however, and so much conflicting information that its come down to this simple question: does whatever youre eating right now make sense?

Well, sense isnt common, and it does depend on some good information. So here is something to consider: what kind of foods are humans evolved to eat? Cheetos? Dont think so. Thats a no-brainer, but what about some others that we counted as healthy staples until recently, like bread and pasta. Go way back in your imagination, to hunter gatherer days before agriculture and the obesity which followed for the first time among humans and consider what would be part of our ancestors normal diet. If youre about to pop something into your mouth that wasnt around before agriculture, (a relatively recent development in human history), then eat it knowing its not considered a normal food by your body. Foods your body considers normal contribute to your health, other foods are either neutral or harmful. How simple is that?

A well-known exploration of this concept that certain foods help our bodies thrive is Dr. Peter DAdamos book, Eat Right 4 Your Type, in which he bases his lists of what to eat and avoid on blood type. DAdamo asserts that type O is the oldest type, and the newer A type didnt show up on the scene until agriculture. So, Os should eat lots of meat and veg because that blood type doesnt know how to handle too much grain. Type As can eat grain, but not dairy. Dairy is a category reserved as a normal food only for the yet more recent human blood type, AB. (Maybe well evolve a new type that can handle Cheetos and red licorice, my personal favorite abnormal foods).

DAdamo supports his blood-type theory with all kinds of careful research, and so what? Does it make sense that humans should rely primarily on foods that occur naturally? Absolutely. If youre going to eat a grain like wheat then, eat it whole, or dont eat it at all, and dont eat much of it anyway because humans pretty much made wheat up! Im not going to take the, Does it occur naturally? debate too far, because its time to look at another researchers take on the food and evolution connection.

Dr. Phillip Lipetz wrote The Good Calorie Diet, a book for the weight loss market, but he also has supported his theories with all kinds of careful research. His describes how the human response to starvation that was developed during the ice age carries on today. Ironic, isnt it, that the food available to us today – rich and sweet and abundant – causes our bodies to behave as though starvation is at hand.

The short story for how this works is that up until the ice age, humans ate whatever was readily available, like roots, plants, fruit, and a little tasty carrion now and then. Along came the ice ages, and those foods became scarce. Now humans were forced to hunt, but it was dicey and the weapons were primitive, so spans of time occured between kills. The result: our ancestors evolved ways to make the most of the conversion of excess blood sugar into stored nutrition in the form of body fat. When they starved, they lived off stored fat.

Todays diet mimics the ice age diet: high fat and high protein, and our genetic programming says, Uh oh, were facing starvation again. Better store up some fat. Lipetz goes into convincing detail about food combinations in his book. He describes some that cause the creation of excess fat, such as butter on bread. More useful are his combinations that actually inhibit fat formation, like lean meat with most vegetables. In a society where obesity and its attendant health issues are rampant, these food combinations are helpful places to focus our attention. Yet the single most useful bit to remember from his research is that foods which cause our bodies to create excess fat all have one thing in common: they werent part of our ancestors normal diet.

Armed with this overview, next time youre about to pop something in your mouth – whether your focus is health or weight you dont need to have a bunch of rules and whacky information in mind. Just use common sense. Ask whether its a food that was around before the advent of agriculture. If it was, go for it. If it wasnt, then consider that your body wont consider the food normal, and in both the long and short run, thats got health consequences.

Nutrition and healthy eating – What you should know
John Gibb

Many people think that they can achieve a healthy lifestyle simply by maintaining a diet that prevents obesity. While keeping trim is one aspect of being nutritionally sound, there are many other factors that figure into getting your body working in the best possible shape.

Your body needs plenty of nutrients to stay in its best condition, and a diet simply isn’t enough. A combination of receiving nutrition and healthy eating can result in great things for your health. For instance, your body requires a daily amount of calcium. If you cannot achieve these daily guidelines, the calcium levels in your blood will drop. This will disrupt nerve communication and hinder blood clotting. If you neglect your calcium levels long enough, the bloodstream will begin to sap the very calcium that makes up your bones. This results in brittle bones, the onset of the dreaded osteoporosis.

Also, it’s important to get your daily vitamins. Vitamins A, B-complex, C, D, E, and K are all necessary on a daily basis to maintain your health. They contain antioxidants that help your body fight off the negative effects of free radicals – molecules that attack the cell membranes in your body. A lack of these vitamins can result in a range of symptoms, from things as simple as chapped lips to long-forgotten diseases such as scurvy, caused by a lack of vitamin C.

Of course, nutrition and healthy eating go hand in hand; while vitamins and minerals are required, it is also important to get the right amounts of protein, carbohydrates, and fat. Without enough protein, your body is unable to repair damaged tissues, or create new tissues. Carbohydrates are key in providing your body with the energy it needs for your day-to-day tasks. Fat is also important, as too low a fat level can be detrimental to the body.

Now that you have an idea of some of the nutrients daily, you need get off your butt and start exercising. Exercise will do wonders for your whole body, mind, and even spiritual state if pursued long enough.

Living a Healthy Life!
Nettie Mae

People are obsessed with dieting and weight loss! Don’t believe me? Just tune-in to any source of advertising…you’re instantly bombarded with the latest diet schemes and “Hollywood” food fads.

Here in America, we have built a thriving industry trying to control our weight and treat the consequences of over-indulgence. The cost of weight loss and obesity related health care treatments is staggering…Americans alone spend around $114 billion every year! And even with all this interest in losing weight, we continue to pack on the pounds like never before…

– A whopping 64 percent of U.S. adults are either overweight or obese…up about eight percent from earlier estimates.

– Among children and teens ages 6-19, 15 percent or almost nine million are overweight…triple the rate in 1980!

– Nearly one-third of all adults are now classified as obese.

For Americans, modern life may be getting TOO easy. Our cushy lifestyle means we expend less energy and consequently need fewer calories to sustain our normal body weight.

Think about it for a moment…

Entertainment no longer requires energy expenditure. In fact, it’s usually quite the opposite. We now entertain ourselves in the comfort of our own home while watching TV and munching on our favorite snack. Whether it’s television, computers, remote controls, or automobiles, we are moving less and burning fewer calories. Common activities that were once a part of our normal routine have disappeared…activities like climbing stairs, pushing a lawn mower or walking to get somewhere.

And please do not misunderstand me…I appreciate comfortable living just as much as the next person. But, here is the problem…

With all of our modern day conveniences and “cushy” style of living we have not adjusted our caloric intake to compensate for our decreased caloric expenditure. We consume more calorie rich and nutrient deficient foods than ever before. Consider a few of the following examples comparing what we eat “today” vs the 1970’s (U.S. Department of Agriculture survey):

– We are currently eating more grain products, but almost all of them are refined grains (white bread, etc.). Grain consumption has jumped 45 percent since the 1970’s, from 138 pounds of grains per person per year to 200 pounds! Only 2 percent of the wheat flour is consumed as whole wheat.

– Our consumption of fruits and vegetables has increased, but only because French fries and potato chips are included as vegetables. Potato products account for almost a third of our “produce” choices.

– We’re drinking less milk, but we’ve more than doubled our cheese intake. Cheese now outranks meat as the number one source of saturated fat in our diets.

– We’ve cut back on red meat, but have more than made up for the loss by increasing our intake of chicken (battered and fried), so that overall, we’re eating 13 pounds more meat today than we did back in the 1970’s.

– We’re drinking three times more carbonated soft drinks than milk, compared to the 1970’s, when milk consumption was twice that of pop.

– We use 25 percent less butter, but pour twice as much vegetable oil on our food and salads, so our total added fat intake has increased 32 percent.

– Sugar consumption has been another cause of our expanding waistlines. Sugar intake is simply off the charts. People are consuming roughly twice the amount of sugar they need each day, about 20 teaspoons on a 2000 calorie/day diet. The added sugar is found mostly in junk foods, such as pop, cake, and cookies. In 1978, the government found that sugars constituted only 11 percent of the average person’s calories. Now, this number has ballooned to 16 percent for the average American adult and as much as 20 percent for American teenagers!

Unfortunately, it would seem that the days of wholesome and nutritious family dinners are being replaced by fast food and eating on-the-run. We have gradually come to accept that it’s “OK” to sacrifice healthy foods for the sake of convenience and that larger serving portions equate to better value.

It’s time recognize that we are consuming too many calories and time to start doing something about it! Each of us can decide TODAY that healthy eating and exercise habits WILL become a normal part of our life!

We can begin by exploring our values, thoughts and habits… slowly and deliberately weed-out the unhealthy habits and activities and start living a more productive and rewarding life. And remember, it has taken a long time to develop bad habits, so be patient as you work toward your goal!

How Healthy Is Your Lifestyle
Loring A. Windblad

Compelling evidence shows that certain lifestyle behaviours can improve health, prevent premature death and may even prolong life. The problem is that people often drift along, continuing their unhealthy ways – maybe vowing to stop smoking or drink less “some day soon” – until a disease or health problem strikes and it may be too late to reverse the damage. Assessing your lifestyle and how it affects health before illness occurs is a wise precaution. (However, changing one’s lifestyle even after illness can sometimes improve health – for instance giving up cigarettes and exercising more after a heart attack.)
Why assess lifestyle risks?
Accumulating scientific evidence shows that a few simple lifestyle habits can directly improve health and decrease disease risks. Much disability and premature death from today’s foremost killers – heart disease, stroke, cancer, diabetes, liver cirrhosis, suicide and unintentional injuries – stem from everyday habits. Over half the premature deaths in North America are blamed on unhealthy behaviours such as cigarette smoking, insufficient exercise, excessive alcohol intake and a fat-laden diet. Only six per cent of premature deaths are considered avoidable through better medical care.
A California study has demonstrated that disease risks can be reduced by not smoking cigarettes, moderating alcohol use, eating breakfast, having regular physical activity, maintaining desirable weight, getting enough (7-8 hours) nightly sleep and having close social networks. The effect is cumulative: the greater the number of good lifestyle habits, the greater the chance of better health and a longer life. A recent Canadian study confirmed a lower chance of premature death by avoiding cigarette smoking, high blood pressure (related to obesity and insufficient exercise), adult-onset diabetes (due to obesity, poor diet, lack of exercise) and excess alcohol consumption. (However, some everyday influences are an unavoidable part of the environment, over which individuals have little control – such as air pollution or traffic noise.)
To evaluate your lifestyle, ask yourself a few key questions about everyday activities such as the amount of fat you eat, smoking and drinking habits – see checklist below – and evaluate which might be improving your health or perhaps damaging it. Consider seeking advice from a health professional about habits you wish to change.
Quick, easy computer programs help rate your lifestyle
To help people assess the health impact of various lifestyle activities, a new Computerized Lifestyle Assessment (CLA) program, developed by the Addiction Research Foundation and the University of Toronto, provides a practical, quick, confidential and easy method of evaluating lifestyle strengths and weaknesses. The computer program, which takes 20 minutes to run, asks detailed questions about 16 lifestyle activities, with graphic feedback along the way and a printed report at the end. Identification and feedback about risk activities that undermine health often lead people to improve their lifestyle and seek advice from a health professional. For details about the CLA program, call (416) 978-8989 or contact the publisher, Multi-Health Systems, at 1-800-268-6011.
The computer program asks questions about.
* substance abuse;
* health maintenance;
* preventive activities;
* social and intimate relationships;
* mental and emotional wellbeing.
The program feeds back information about:
* lifestyle strengths or activities to keep up
* areas of concern or factors that can threaten health
* risk areas requiring action to prevent disease
The final printout pinpoints health-harming behaviours, some of which may come as a surprise, others that may be known to the person who might be “thinking about” changing them. For example, a woman who thinks she leads a healthy life – doesn’t smoke, drink or take other drugs, eats a low-fat vegetarian diet and exercises three times a week – may have emotional problems stemming from poor social relationships and a perfectionist attitude. Or, a man who doesn’t smoke, drinks little alcohol and has good work and personal relationships may endanger his health by being overweight with the beginnings of diabetes, hypertension and a potential heart problem.
Curiously, computers sometimes elicit more personal information about sensitive lifestyle areas than a doctors interview. For instance, many people find it easier to report excess alcohol consumption to a computer than to a physician. Women, especially, seem more likely to confide alcohol, sexual and other problems to a computer than to a doctor. Computerized psychiatric histories sometimes spot problems missed by clinicians – such as suicidal thoughts, anxiety, depression or phobias.
Adolescent and student lifestyles especially poor. One recent study found that seven out of 10 people questioned were particularly worried about nutrition and half were also concerned about physical inactivity. A study of Queen’s University students found that over 80 per cent fail to get regular medical/dental care, and over half consume excess alcohol and have poor management of work-leisure time.
Study results show student health problems with:
* Alcohol:
* Cannabis:
* Cigarettes:
* Stress:
* Inactivity:
* Weight:
* Sex:
* Condom use:
Adolescent eating habits can endanger health. Many adolescents receive inadequate nutrition due to poor diets, irregular eating habits and eating disorders that stem from the wish to conform to society’s idealization of thinness. “Weight control” techniques such as self-induced vomiting and diarrhea are widespread. A recent U.S. National Adolescent Health Survey found 61 per cent of adolescent females and 28 per cent of adolescent males were dieting, 51 per cent often fasted, 16 per cent used diet pills and 12 per cent practiced vomiting.
Teens had poor dietary practices because of:
* Excessive preoccupation with physical appearance;
* Western society’s obsession with thinness;
* Eating disorders such as Anorexia Nervosa and Bulimia.
Lifestyle habits can improve health:
* not smoking tobacco;
* maintaining desirable weight (avoiding obesity);
* good nutrition (following Canada’s Food Guide);
* exercising regularly and sufficiently (at least 30 minutes three times a week);
* getting enough sound nightly sleep (7-8 hours);
* avoiding accidental injuries by taking safety measures (such as seatbelts and helmets);
* practicing motor vehicle safety;
* moderating alcohol use;
* avoiding other recreational drugs;
* getting regular dental care and medical check-ups as advised;
* fostering family, work and social networks;
* having safe and satisfying sexual relationships;
* avoiding or learning how to cope with excess stress;
* enjoining sufficient leisure-time activities and relaxation;
* getting any needed therapy for mental problems.
Lifestyle changes occur in five stages
Stage 1: Pre-contemplation – the health risk of a particular life-style activity is (largely) unrecognized, denied or trivialized.
Stage 2: Contemplation – admitting to a health risk and thinking about making a change “some day.
Stage 3: Preparation – motivated and ready for change “soon”, planning how and what to do, often setting an actual date.
Stage 4: Action – active steps to change behaviour – e.g., giving up cigarettes, walking to work instead of driving, drinking less – setting a specific schedule and definite goals.
Stage 5: Maintenance – long-term change achieved and kept up.
Just asking can make a difference. Surveys show that many people expect physicians or nurses to ask about and give advice or information regarding health. Given the chance, many people would like to discuss lifestyle concerns such as nutrition, obesity, alcohol,other drug use, family conflicts, elderly relatives, sexual problems and chronic pain – but often hesitate to do so unless asked.
