The Question of Alcohol in you Diet

Alcohol, like caffeine and nicotine, is a drug. As such, it is capable of bringing about serious damage to mind and body when taken over a long period of time. Made from the fermentation of carbohydrates with yeast enzymes, alcohol is rapidly absorbed through the digestive system, affecting coordination of the muscles, nerves, and vision. It also stimulates stomach secretions, inhibits mobilization of lymphocytes so that the body's ability to fight infection is reduced, and causes sludging in the red blood cells, thereby reducing oxygen to the heart and lungs. And it affects the brain, adversely affecting the specific centers that govern self- control, judgment, and personal inhibitions.

Alcohol is a depressant. The transient feeling of well-being that goes with a couple of glasses of whisky or a dry martini—the "lift"—is followed by a series of miseries to which your body is subjected, not the least of which, for a woman, is the effect drinking alcohol has on the liver. And the insidious thing about the detrimental effects which alcohol has on health and beauty is that they occur even to the average social drinker, not just to the serious drinker and the alcoholic.

A joint study by Dr. Charles S. Leiber of the Section of Liver Disease and Nutrition at Bronx Veterans Administration and Dr. Emanuel Rubin of the Department of Pathology at Mount Sinai School of Medicine showed that too much social drinking can cause serious damage to the liver, even though the drinker may feel fine, act normally under the influence of alcohol, and not be an alcoholic. Leiber and Rubim took a group of healthy nonalcoholic volunteers and put them on a carefully controlled eight-day drinking regimen. Then they tested the subjects' livers to see what changes, if any, the alcohol had caused. The amount given to a particular group was considered equivalent to the average intake of a business executive-7 ounces of 86-proof whisky per day for the first four days, 11 ounces for the new two, and then 14 ounces for the last two. The results were surprising: there was an increase in the fat levels in the subjects' liver of from five to thirteen times, all in only eight days, and in spite of the fact that the diet of the subjects had been supplemented with vitamins.

Similar studies have turned up similar results. Researchers have also found that liver-cell damage and the increase in fat in the liver can be reversible if the drinker abstains from alcohol for long enough. But longterm damage to the liver resulting from daily consumption of alcohol over the years can be irreversible. Persistent drinking can also be a precursor not only to specific diseases of the liver such as cirrhosis, but also to other toxic conditions in the body.

Next to the skin, your liver is your body's largest organ. In many ways it is also the most important. One could, for instance, live without a stomach if necessary but never without a liver. It is the body's chemical purifier, performing more than five hundred different functions, many concerned with detoxifying the system from all the drugs, pollutants, and poisons you take in every day, including alcohol. If the liver is overworked or worn out by excess alcohol consumption, eventually and unavoidably your whole body suffers. Biochemists used to believe that excess alcohol was no more damaging to the liver than too much sugar or too much fat in the diet; that the real damage to the liver came only from malnutrition. But these theories have been disproved. Both the quantity of alcohol you drink and the duration of time over which you drink it are important factors in determining liver damage.

Because the liver is responsible either directly or indirectly for controlling levels of many hormones in a woman's body (particularly estrogen), when liver damage occurs as the result of a diet too high in fats or of drug taking or long-term alcoholic consumption, the endocrine balance can be severely upset, leading not only to disruption of the menstrual cycle but also indirectly to feelings of depression, anxiety, and chronic fatigue.

These troubles may have another cause, also related to alcohol. In order to metabolize alcohol, your body calls on its reserve of many B- complex vitamins which act as coenzymes in the process. When one eats foods containing natural concentrations of carbohydrates or sugar, such as grains and fruits, the B-complex vitamins necessary for their proper digestion and assimilation are provided by nature in the foods themselves. But the B-complex vitamins have been discarded in the processing of highly refined sugars and alcohol. So the body's own reserves can easily get depleted when you drink alcohol and eat refined sugars. Results of this depletion are many, the most common of which can be fatigue, a craving for more alcohol or sweets, or diverse emotional complaints from severe premenstrual tension to simple feelings of chronic misery.

These are just some of the reasons why the Lifestyle Diet excludes alcohol in quantities of more than a glass of wine a day. This may seem like a tremendous sacrifice to you if you are used to taking a great deal more, but once you eliminate stimulants such as coffee, tea, and alcohol from your life and begin to experience the enormous sense of well-being that comes with the low fat, low protein, complex carbohydrate diet (and all the other important things that also go with discovering and expressing your potentials mentally and physically, such as deep relaxation and exercise), you will never miss it.

Don't turn your back on calcium continue…

You may even be at greater risk if you consider the other factors that contribute to osteoporosis:

  • The decline in oestrogen. Up to half of women over the age of 45 have some degree of type 1 osteoporosis (bone loss is most profound during the first decade after menopause).
  • Smoking. It suppresses the activity of the osteoblasts (the bone-building cells) and also causes changes in oestrogen metabolism in women, resulting in an earlier menopause.
  • Being thin and/or fine-boned.
  • Excessive use of alcohol. This reduces calcium absorption and damages liver and bone cells.
  • Avery high intake of protein increases the amount of calcium lost by the body. Veganism. Avoiding all animal products means avoiding some of the richest sources of calcium.
  • Lack of exercise. Physical inactivity or prolonged bed rest are associated with the loss of bone density. Astronauts experience noticeable bone loss when in space, due to the effects of weightlessness.
  • Excessive, long-term use of salt, in addition to being bad for your health in general, leads to increased calcium loss from your bones.
  • Pregnancy and lactation. If there is insufficient calcium in your diet while you are pregnant or breasffeeding, calcium will be drawn from your bones and teeth to provide for the growth of the baby.
  • Little or no exposure to the sun. Housebound people, elderly folk and office workers often don't enjoy enough sunlight to assist their skins in the manufacture of vitamin D, which is needed for the absorption of calcium from the gastro-intestinal tract.
  • Unbalanced diets. Not only quick-fix slimming diets are low in nutrients. Our average, modern-day diets often lead to an insufficient intake of nutrients. Although you might be taking in sufficient calcium-rich foods (like cheese!), you might be taking in too little of the other bone-fortifying nutrients such as vitamin D, magnesium (soy, dried beans, nuts), zinc (chicken heart and liver, beef liver, lamb), copper, manganese and boron, found in a large variety of other foods.
  • Genetic inheritance accounts for 80% of the variance in peak bone mass. Blacks have a higher bone mass than whites and Asians, and men have a higher bone density than women. A strong family history is a risk factor for osteoporosis - daughters of women with osteoporosis have been shown to have lower-than-expected bone density.
  • Certain health conditions such as diabetes, rheumatoid arthritis, Cushing's syndrome, amenorrhoea resulting from anorexia nervosa and/or excessive exercise, gastrectomy, immobilising diseases, male hypogonadism (low testosterone levels), chronic liver disease or malabsorption.
  • Consumption of large amounts of black coffee over a long period of time.
  • Hyperthyroidism and over-treatment with thyroxin.
  • The prolonged use of drugs such as corticosteroids (cortisone).

What is the role of calcium in theJody?

Everyone knows that calcium is required for healthy bones and teeth, but most people believe that calcium is only important in childhood. Wrong! There is a need for calcium throughout one's life in order to build and maintain calcium levels in bone.

Diet Start

Calcium acts as a metabolic regulator. Changes in the level of calcium within the cell result in the switching on and off of the processes of muscle contraction and nerve excitation.

Calcium is also involved as a co-factor in many enzyme processes. It is needed in cell division, the immune system and is also required in order for blood to clot.

More recently there has been some evidence to suggest that calcium has a positive role to play in maintaining a healthy blood pressure.

Clearly, calcium is an essential nutrient and a major role player in our general wellbeing; good health being an essential prerequisite for shedding weight successfully and permanently.

Dietary sources of calcium

The major foods in the diet that contain calcium, include milk, cheese, yoghurt, white bread, white flour, and green vegetables. The absorption of calcium by the body is dependent on many factors, including the form of calcium in the food. The best sources of available calcium are dairy foods. Green vegetables and whole grain cereals contain phytates that bind calcium and prevent absorption.

A balanced diet is important for the provision of calcium and other bone fortifying nutrients throughout your life.
