Why Paleo??

Some answers to why we prefer the Paleo Diet or Paleo based zone.. Somethings you might not know about food. This is an in depth look @ some of the info we fed you during the nutrition seminar.

Paleolithic Diet buffs refer to the new foods as Neolithic foods and the old as Paleolithic Diet foods. In simple terms we see Neolithic as (bad) Agricultural age and Paleolithic as (good) Stone age. Since then, some other substances have entered the diet- particularly salt and sugar, and more recently a litany of chemicals including firstly caffeine then all other additives, colourings, preservatives, pesticides etc.

Grains, Beans and Potatoes (GBP) share the following important characteristics:

· They are all toxic when raw- there is no doubt about this- it is a fact that no competent source would dispute- they can be extremely dangerous and it is important never to eat them raw or undercooked. These toxins include enzyme blockers, lectins and other types. I will talk about them in detail later as they are very important.

· Cooking destroys most but not all of the toxins. Insufficient cooking can lead to sickness such as acute gastroenteritis.

· They are all rich sources of carbohydrate, and once cooked this is often rapidly digestible-giving a high glycemic index (sugar spike).

· They are extremely poor sources of vitamins (particularly vitamins A, B-group, folic acid and C), minerals, antioxidants and phytosterols.

Therefore diets high in grains beans and potatoes (GBP):

· Contain toxins in small amounts

· Have a high glycemic index (ie have a similar effect to raw sugar on blood glucose levels)

· Are low in many vitamins, minerals, antioxidants and phytosterols- ie they are the original "empty calories"

· Have problems caused by the GBP displacing other foods

As grains, beans and potatoes form such a large proportion of the modern diet, you can now understand why it is so common for people to feel they need supplements or that they need to detoxify (ie that they have toxins in their system)- indeed both feelings are absolutely correct. Unfortunately, we don’t necessarily realize which supplements we need, and ironically when people go on detoxification diets they unfortunately often consume even more Neolithic foods (eg soy beans) and therefore more toxins than usual (perhaps they sometimes benefit from a change in toxins).

The reason why grains, beans and potatoes store so well is simply because of the toxins that they contain. The enzyme blockers put them into a deep freeze, stopping them from sprouting. The lectins and other toxins are natural pesticides and can attack bacteria, insects, worms, rodents and other pests (and humans too of course).

They also have a knack for bypassing our defenses and "getting behind the lines", and then they can travel all over the body causing harm. They can, for example:

--strip protective mucus off tissues,

--damage the cells lining the small intestine- disrupting the microscopic fingers called villi and microvilli,

--get swallowed whole by the small intestine cells ("pinocytosis")

--bind to cells including blood cells causing a clot to form (hence they were initially called "haemagglutins")

--make a cell act as if it has been stimulated by a hormone-

--stimulate a cell to secrete a hormone

--promote cell division at the wrong time

--cause gowth or shrinkage of lymphatic tissue ("outposts" of white blood cells)

--cause enlargement of the pancreas

--cause cells to present codes (HLA's) that they normally should not use

--cause cell death (apoptosis)

Lectins break down the surface of the small intestine, stripping it of mucus and causing the cells to become irregular and leaky. Some lectins make cells act as if they have been stimulated by insulin. Others cause the pancreas to release insulin. Others cause immune cells to divide in the wrong way, causing growth of some white blood cells and breaking down the control of the immune system. Others cause cells to present the wrong codes (HLA's) on their surface, tricking the immune system into thinking that intruders have been found and activating the immune system inappropriately- thus leading to "autoimmune disease" where the body's tissues are attacked by its own immune system.

Autoimmune diseases are incredibly common and increase every year that a person gets older. A disordered immune system also has a much harder job recognizing and attacking the real intruders- invading germs and cancer cells (you may have heard that scientists think that most people generate many cancer cells in a life time but that the immune system cleans most of them up).

It is not known whether lectins can cause cancer- this is one of the most important questions in medicine today. They certainly affect colon cells in the test tube. I feel that they are likely candidates as they can stimulate abnormal cell growth and they also cause disorder in the immune system.

Lectins have many other roles besides defending seeds. For example in beans, lectins act like a glue to enable nitrogen-fixing bacteria to bind to the roots of the plant. Many important lectin families are found in animal tissues, but as we are carnivores, we have evolved to be able to deal with these- just as birds that live on grains have evolved to be resistant to grain lectins.

It is ironic that the lectins were discovered more than 100 years ago and yet so many questions remain unanswered- the same was true of the immune system until the 1980’s. I hope that there is more research done into lectins as they hold a whole world of disease mechanisms of which most of the medical community is blissfully unaware.

Excerpts from studies done by Dr. Ben Balzer

Enough about the bad stuff lets eat!!!

Stir Fried Beef with Vegetables

2 tablespoons canola oil

1 clove garlic, pressed

12 ounces boneless sirloin steak, trimmed of all visible fat, thinly sliced

¼ cup burgundy wine

1 yellow onion cut thinly into wedges

1 red pepper, seeded and cut into slender strips

2 celery stalks, chopped

4 ounces of sliced mushrooms

4 ounces thinly sliced carrots

3 tablespoons lemon juice

Sauté the beef in the oil with garlic and half of the red wine until the beef is browned. Remove from skillet. Heat the residual oil in the skillet. Sauté the onion, celery, red pepper, and carrots until the onion is tender – about 4 minutes. Add the remainder of the red wine. Add the mushrooms; stir-fry everything together for about another 3 minutes. Combine the vegetables with the meat.
