Vitamin D is only one of a very small number of natural nutrients that are known to prevent and treat many types of potentially life-threatening conditions. Up until the age of 40 sun exposure provides the best source of vitamin D, but conversion of the nutrient declines as we age and supplementation using an oil-based gelcap is necessary to maximize blood saturation and lower cancer risk.
While many are trying to synthesize blood or reproduce its effects, as of today there is no substitute. And every two seconds, someone needs blood. This year alone, more than 5 million patients will require blood transfusions as they recover from accidents or surgery or receive treatment for leukemia, cancer and other diseases.
Giving blood is a way to support the community by helping to ensure that a stable inventory is available for premature babies, cancer patients and the many people who suffer accidents and other illnesses which may require transfusions. Blood has a shelf life of only 42 days, and, therefore must continually be replenished. Donors can give blood every 56 days, or up to six times a year.
Trish Gutierrez of San Angelo knows the importance of blood donation. "Almost every member of my family has needed blood at some point. I have had three hip replacements and needed blood transfusions," she said. "My uncle needed 21 units of blood recently."
I was on a mission to meet Gutierrez. After all, she was the driving force behind the overwhelming student response at the Howard College blood drive in the fall. I wanted to know what her secret was. I struggle every day with the statistic that states that while 60 percent of the population is eligible to donate, only 5 percent do so — and on some days, that percentage is zero. Gutierrez more than overcame that statistic, and I wanted to know how — maybe I could bottle it and release it into the air when our blood supply becomes dangerously low.
Gutierrez is an instructor at Howard College. She is a psychology professor, teaches six or seven classes every semester and instructs between 200 and 300 students. She has been at Howard College for 18 years.
Gutierrez was familiar with the blood donation process at an early age while growing up in Arkansas City, Kan. Her mother, Ann Long, was very involved in the community. Gutierrez's father did not want his wife to work for wages, so she spent her time giving back to the community. Long would organize community blood drives and Gutierrez accompanied her — well actually, "Mom drug me along," as Gutierrez related. Too young to donate, Gutierrez was the snack supplier for the donors.
When Gutierrez became old enough to donate blood, she did so. She even has the photo that was published in the local newspaper to prove it.
"Hate to say it, but it's in our blood," said Gutierrez. She laughed because of course she was talking about blood donation. While Gutierrez is not currently eligible to donate, she encourages her students to do so.
Gutierrez is on the community involvement committee at Howard College. She said the Howard College blood drives are "our pet project." Gutierrez is an inspiration to her students when it comes to encouraging them to donate blood. Whatever she does, it really works because blood drive participation has increased dramatically.
Gutierrez grinned and told me, "I met my husband while donating blood at the State Hospital in Big Spring." She assured me she was not a patient at the time. She asked to have the bed by the window on the bus so she could watch the men working outside the bus. "He caught my eye and then he waved at me. I told my friend who was donating at the same time, 'I'm telling you, I'm going to marry that man.'" She did marry that man and they have been together ever since.
I give a big thank you to Gutierrez. Not just because she has a great way to encourage her students to donate blood, but also because she has added one more benefit to blood donation: You just might find your soul mate while donating blood.
And if you give blood by Feb. 25, you'll be a part of the Straight from the Heart blood drive. You'll get:

Keeping in good shape has always been important to 27-year-old Kate Millet.
Although never obsessive, the events manager stuck to a diet full of fruit and vegetables, avoided fatty foods, drank green tea and exercised every day.
She’d also given up eating meat.
‘I had concerns about the fat content of red meat and had read that eating large amounts of it was linked to bowel cancer and heart disease.’
Yesterday Britons were being warned to cut down on red meat to reduce the risk of cancer. Under new Department of Health guidelines, adults will be advised to eat no more than 500g a week. Many will cut out meat altogether — but, as Kate learned, this can have unexpected consequences.
One day she was out running when she suddenly felt very light-headed.
‘I was totally drained and knew I couldn’t run a step further — it was like all my energy had been used up and I thought I would collapse,’ says Kate, from London.
‘That night, my boyfriend Howard told me I was too pale and lacking energy, and he was worried about me. He was right: I was coming home from work exhausted, and had a cold I couldn’t shift.’
Kate saw her GP, and was astonished to discover she was anaemic — she had such low stores of iron that her body couldn’t make enough haemoglobin. This is a key component of red blood cells that helps transport oxygen around the body.
This lack of oxygen triggers symptoms such as fatigue, poor concentration, tiredness and dizziness.
Long-term effects include brittle hair and difficulties swallowing. In severe cases anaemia can cause chest pain, headaches and leg pains, and even lead to permanent changes to the lining of the throat, a precursor to cancer.
What was so surprising was what had caused Kate’s anaemia — her apparently healthy lifestyle.
‘I didn’t know anyone who looked after their health as well as I did,’ she says.
‘I went out of my way to eat foods like spinach, which I thought were iron-rich as I knew this was important.
‘I didn’t eat processed food, but always cooked meals from scratch using lentils and tofu. I took care to eat eggs and pulses for protein and filled up on bran flakes and milk for breakfast.’
Meat on a plate
Apart from the possible health risks - or not - of red meat, women are shunning it because they think it's fattening
Kate’s GP explained that her avoidance of red meat, the exercising and even the green tea had left her seriously lacking in iron.
Kate is one of an increasing number of women unwittingly putting themselves at risk of anaemia in pursuit of a healthy lifestyle.
One in four British women has an iron intake below the recommended 14.8mg a day. While all age groups are affected, 25 to 34-year-olds are particularly deficient, with up to 40 per cent lacking iron.
‘Iron deficiency is the most common nutritional deficiency in the UK,’ says Dr Emma Derbyshire, a senior lecturer in nutrition at Manchester Metropolitan University.
Dr Derbyshire believes the blame lies partly with recent health scares about meat, particularly the link between its high fat content and heart disease and bowel cancer.
In fact, recent messages about red meat have been confusing: just last week a British Nutrition Foundation study claimed that most adults ate ‘healthy amounts’ of red meat and the link to cancer was ‘inconclusive’.

* Yes, your blood group DOES affect your health
* So how much red meat CAN we eat? Latest warning suggests too much will cause cancer
Then this week new guidelines drawn up by the Department of Health warned that while red meat is a valuable source of iron, eating too much can lead to cancer and heart disease.
Apart from the possible health risks — or not — of red meat, women are shunning it because they think it’s fattening.
As a result, women’s red meat consumption has plummeted — from an average of 161g per week in 2003 to just 91g in 2008, a drop of 40 per cent.
In fact, lean red meat such as steak is healthy and one of the best sources of iron, explains Dr Derbyshire.
‘The key is to stick to lean, unprocessed meat,’ she adds.
Another problem is that foods people think are iron-rich — such as spinach, chard, lentils, almonds and cashew nuts — contain a chemical called oxalic acid which can inhibit iron absorption.
Meanwhile, high-fibre foods such as fruits and vegetables contain chemicals called phytates which can slow down iron consumption.
Certain foods and drinks can also cause problems.
‘Tea, coffee and red wine contain compounds called polyphenols which, if drunk with your meal inhibit absorption of iron from vegetable sources,’ explains Dr Derbyshire.
Excessive exercise such as running can deplete iron stores — the impact of the foot on hard surfaces causes red blood cells to break down quicker, so iron is lost.
Given the confusion about the health risks of red meat, Dr Derbyshire believes we need guidelines on its consumption ‘just as we have about fish — saying we need a minimum of two portions a week’.
What about iron supplements? High iron levels are a risk factor for heart attacks, so people are advised not to take iron unless they’ve had a blood test which reveals they are iron-deficient.
Because her iron levels were so low, Kate Millet has to take a liquid iron supplement, Spatone. But within two months of changing her diet, she had regained her energy levels.
‘I drink orange juice with meals to boost iron absorption and avoid tea or coffee with food,’ she says.
‘I even eat two small portions of red meat a week, and I snack on iron-rich foods such as liquorice and sesame seeds.
‘I now know I need more than spinach and lentils to stay healthy.’
SO WHAT MAKES IT SO RISKY?
The new warnings issued yesterday over eating large amounts of red meat reignited debate about whether it does raise the risk of cancer and heart disease. But why would red meat be so bad for you?
TOO MUCH FAT: Animal fat has been linked with a wide range of cancers. But evidence suggests it’s not the amount you eat that counts, rather the amount that is stored as body fat. Scientists think carrying excess fat triggers a state of chronic inflammation in body tissues, which sparks cancer growth and heart disease.
CHEMICALS USED IN PROCESSING: Preservatives used in processed meats such as bacon, ham, sausages and pate kill food poisoning bugs and help keep the meat pink, but may damage the DNA of healthy cells in the stomach. ‘But adding ketchup, which contains antioxidants, to your bacon sandwich could help prevent that damage,’ says Catherine Collins, chief dietician at St George’s Hospital in London.
CHARRED MEAT: Grilled or charred meat releases different chemicals which bond together to form potentially cancer-causing compounds. Catherine Collins says eating a yogurt dip at the same time ‘neutralises their effect on the bowel’.
TOO MUCH IRON: Excess iron can damage cells in the bowel, increasing the risk of cancer. Eat meat with fibrous foods such as vegetables, to reduce the amount of time it lingers in the body.
SO WHAT MAKES IT SO RISKY?
Lean, unprocessed meat is the best source of easily absorbable iron — it also provides vital protein, vitamins and minerals.
Under new guidelines, Britons are to be advised to eat no more than 70g of red or processed meat a day.
* Choose cuts from the leg or loin of an animal. If you’re having a steak, choose a rump or sirloin cut. Least healthy is the rib eye: an 8oz steak has around 500 calories and 15g saturates — three-quarters of the recommended daily maximum. Offal — including liver, kidneys, tongue and tripe — is a good choice, as it is rich in protein and contains B vitamins, good for energy release and the nervous system.
* Avoid shoulder, ribs, belly, and neck and breast (of lamb), as these are higher fat, as are minced meats and sausages, even when grilled. The World Cancer Research Fund advises against processed meats such as ham, salami, hot dogs and bacon. Smoking or curing meat, or adding preservatives, cause the formation of carcinogens.
* The most sinful of all meat products is the doner kebab — an average portion supplies nearly all of an adult’s recommended daily salt content and 50 per cent more saturated fat than an adult should eat in a day.
