Benefits of Cauliflower

Cauliflower and other cruciferous vegetables, such as broccoli, cabbage, and kale, contain compounds that may help prevent cancer. Epidemiological studies have long suggested a connection between these vegetables and resistance to cancer. Both animal and human studies show increased detoxification enzyme levels from high-glucosinolate diets. New Research Expands our Understanding of How Cruciferous Vegetables Help Prevent Cancer

New research has greatly advanced scientists' understanding of just how cruciferous vegetables such as cabbage, cauliflower, broccoli, kale and Brussels sprouts help prevent cancer. Sulforaphane, a compound formed when cruciferous vegetables are chopped or chewed, is already known to trigger the liver to produce enzymes that detoxify cancer-causing chemicals, inhibit chemically-induced breast cancers in animal studies, and induce colon cancer cells to commit suicide.

Human population as well as animal studies consistently show that diets high in cruciferous vegetables, such as cauliflower, are associated with lower incidence of certain cancers, including lung, colon, breast and ovarian cancer. Average daily intake of cruciferous vegetables was significantly lower in those with bladder cancer than in healthy controls.

Those eating the most cruciferous vegetables were found to have a 29% lower risk of bladder cancer compared to participants eating the least of this family of vegetables.

Recent studies show that those eating the most cruciferous vegetables have a much lower risk of prostate, colorectal and lung cancer-even whencompared to those who regularly eat other vegetables:

In a study of over 1,200 men, conducted at the Fred Hutchinson Cancer Research Center in Seattle, WA, those eating 28 servings of vegetables a week had a 35% lower risk of prostate cancer, but those consuming just 3 or more servings of cruciferous vegetables each week had a 44% lower prostate cancer risk.

In smokers, regular cruciferous vegetable consumption reduced lung cancer risk an amazing 69%!

How many weekly servings of cruciferous vegetables do you need to lower your risk of cancer? A Weekly Serving of Cruciferous Vegetables Halves Advanced Prostate Cancer Risk

Compared to men eating one serving of cauliflower per month, those enjoying a weekly serving lowered their risk of advanced prostate cancer by 52%. Consumption of cruciferous vegetables, such as cauliflower, is known to reduce the risk of a number of cancers, especially lung, colon, breast, ovarian and bladder cancer. Cauliflower, a cruciferous vegetable, is in the same plant family as broccoli, kale, cabbage and collards. Tips for preparing cauliflower

Cauliflower contains phytonutrients that release odorous sulfur compounds when heated.

Spinach for your health

Calorie for calorie, leafy green vegetables like spinach with its delicate texture and jade green color provide more nutrients than any other food. Although spinach is available throughout the year, its season runs from March through May and from September through October when it is the freshest, has the best flavor and is most readily available.

Health Benefits

We all know that Popeye made himself super strong by eating spinach, but you may be surprised to learn that he may also have been protecting himself against osteoporosis, heart disease, colon cancer, arthritis, and other diseases at the same time.

Phytonutrient Flavonoids for Optimal Health

Researchers have identified at least 13 different flavonoid compounds in spinach that function as antioxidants and as anti-cancer agents. (Many of these substances fall into a technical category of flavonoids known as methylenedioxyflavonol glucuronides.) The anticancer properties of these spinach flavonoids have been sufficiently impressive to prompt researchers to create specialized spinach extracts that could be used in controlled studies. These spinach extracts have been shown to slow down cell division in stomach cancer cells (gastric adenocarcinomas), and in studies on laboratory animals, to reduce skin cancers (skin papillomas). A study on adult women living in New England in the late 1980s also showed intake of spinach to be inversely related to incidence of breast cancer.

Spinach Carotenoid Combats Prostate Cancer

A carotenoid found in spinach and other green leafy vegetables fights human prostate cancer two different ways, according to research published in the the Journal of Nutrition. The carotenoid, called neoxanthin, not only induces prostate cancer cells to self-destruct, but is converted in the intestines into additional compounds, called neochromes, which put prostate cancer cells into a state of stasis, thus preventing their replication.

Spinach Flavonoid Combats Ovarian Cancer

Research calculating flavonoid intake in 66,940 women enrolled in the Nurses Health Study between 1984 and 2002 revealed that women whose diets provided the most kaempferol had a 40% reduction in risk of ovarian cancer, compared to women eating the least kaempferol-rich foods. In addition to spinach, foods richest in kaempferol include tea (nonherbal), onions, curly kale, leeks, broccoli, and blueberries.

A significant 34% reduction in ovarian cancer risk was also seen in women with the highest intake of the flavone luteolin (found in citrus). Int J Cancer. 2007 Apr 30; Am J Clin Nutr. 2004 May;79(5):727-47.

Helping You Bone Up

The vitamin K provided by spinach-almost 200% of the Daily Value in one cup of fresh spinach leaves and over 1000% of the Daily Value in one cup of boiled spinach (which contains about 6 times as much spinach)-is important for maintaining bone health. Vitamin K1 helps prevent excessive activation of osteoclasts, the cells that break down bone. Additionally, friendly bacteria in our intestines convert vitamin K1 into vitamin K2, which activates osteocalcin, the major non-collagen protein in bone. Osteocalcin anchors calcium molecules inside of the bone. Spinach is also an excellent source of other bone-building nutrients including calcium and magnesium.

Cardiovascular Protection from Spinach

For atherosclerosis and diabetic heart disease, few foods compare to spinach in their number of helpful nutrients. Spinach is an excellent source of vitamin C and vitamin A, the latter notably through its concentration of beta-carotene. These two nutrients are important antioxidants that work to reduce the amounts of free radicals in the body; vitamin C works as a water-soluble antioxidant and beta-carotene as a fat-soluble one. This water-and-fat-soluble antioxidant team helps to prevent cholesterol from becoming oxidized. Oxidized cholesterol is able to stick to and build up in blood vessel walls, where it can cause blocked arteries, heart attack or stroke. Getting plenty of vitamin C and beta-carotene can help prevent these complications, and a cup of boiled spinach can provide you with 294.8% of the daily value (DV) for vitamin A along with 29.4% of the DV for vitamin C.

Top 10 foods to control cholesterol

Research shows that more than 5.5 million South Africans are at risk for disease due to their high cholesterol levels. Are you one of them?

Then you might be interested to know that certain foods can be particularly useful in controlling your cholesterol levels. We did the legwork for you and listed them here.

Note that these foods are arranged in random order, and that being listed first doesn't mean that the specific food or food group is superior to any of the others. Also keep in mind that it's essential to always follow a varied diet that contains foods from all the different food groups.

1) Olive oil and olive products

Olive oil is rich in monounsaturated fatty acids and vitamin E. Research has shown that foods with a high monounsaturated fatty acid content lower 'bad' low-density lipoprotein (LDL) cholesterol and increase 'good' high-density lipoprotein (HDL) cholesterol.

Anyone with raised cholesterol levels needs to increase his HDL cholesterol and lower his LDL cholesterol levels, which olive oil and products made of olives, will promote.

Have 1-2 tablespoons of olive oil a day over salads or use for cooking, and add some olives to your salads. Keep an eye open for margarine made from olive oil as this also has the benefit of a high monounsaturated fatty acid content.

2) Polyunsaturated, 'lite' and Flora pro-activ margarine

Soft or tub margarine with a high polyunsaturated fatty acid content will also help to lower LDL cholesterol.

Then there are the 'lite' margarines, which have a reduced fat, energy and salt content – all factors that can contribute to heart health.

Flora pro-activ margarine has been specially developed to lower LDL cholesterol by up to 25% if you use it every day. This type of margarine contains added plant sterols that prevent the uptake of fats from the diet and lower blood fat levels. You can use this margarine to replace butter or other types of margarine on bread and cooked vegetables.

3) Legumes

Legumes include dry, cooked or canned beans, lentils, peas and all the soya products (soya beans (cooked or canned), soya mince, cubes, milk, tofu and tempeh).

Legumes have a high dietary fibre content and are rich in protective nutrients, including minerals, B vitamins and phytonutrients. These nutrients protect the heart and the dietary fibre content lowers cholesterol and energy intake.

Legumes are also naturally low in fat and don't contain any cholesterol. On top of this, they have a low glycaemic index (GI). The South African Food-based Dietary Guidelines recommend that we should eat dry beans, peas, lentils and soya regularly.

Make an effort to eat legumes at least 3-4 times a week, or even better still, every day.

4) Fat-free yoghurt and other fat-free dairy products

Full-cream dairy products and most cheeses have a high saturated fat content and need to be avoided if you have raised cholesterol levels.

However, this doesn't mean that you should cut out this food group altogether. Cutting out dairy products will deprive you of calcium, a mineral that's essential for the healthy functioning of the heart and many other important roles in the human body, such as the prevention of osteoporosis.

You can, however, use fat-free milk, yoghurt and cottage cheese in a low-cholesterol diet. Once the fat has been removed from a dairy product, it also removes practically all the cholesterol.

Fat-free yoghurt is a particularly good choice as it is rich in protein, calcium and Lactobacillus microorganisms which may help to lower blood cholesterol levels.

5) Antioxidant-rich fruit and vegetables

All fruits and vegetables can help to lower cholesterol and protect the heart. Two groups are particularly useful, namely those fruits and vegetables that are rich in vitamin C, or rich in beta-carotene.

a) Vitamin C

Foods rich in vitamin C include all the citrus fruits (oranges, grapefruit, lemons and naartjies), all berry fruits (cranberry, strawberry, blackberry etc.), guavas, spanspek, mangoes, the entire cabbage family (green and Chinese cabbage, broccoli, Brussels sprouts), as well as sweet and chilli peppers

b) Beta-carotene

Foods rich in beta-carotene include all dark yellow fruits (apricots, yellow peaches, spanspek and mangoes) and vegetables (pumpkin, sweet potatoes, butternut, carrots) and all dark green vegetables (broccoli, cabbage and spinach).

If you have heart disease or raised cholesterol levels, make sure you get your five portions of fruit and vegetables per day.

6) Garlic and other members of the onion family

Garlic has been used for centuries to promote good health. Research shows that members of the allium family, such as garlic, spring onions and other onions, can be used to lower cholesterol and protect the heart. Use garlic liberally in cooking and on fresh salads.

Researchers believe that the high garlic content of the so-called Mediterranean diet is one of the factors that makes this diet so heart-friendly.

7) Whole, unsifted or unprocessed grains

All unsifted and unprocessed grains and cereals, and the foods produced from unmilled flour, are rich in B vitamins, minerals and dietary fibre (both soluble and insoluble), but low in fat and cholesterol.

Grains and cereals made of unprocessed wheat (wholewheat and seedbread, crackers, high-bran cereals) help to ensure regularity because they have a high insoluble fibre content. On the other hand, oats and oat bran have a high soluble fibre content which can actively lower blood cholesterol levels.

Have a bowl of oats or muesli, which contains raw oats, every day to keep your cholesterol in check.

8) Fish

Researchers have discovered that people who eat fish three or more times a week are less likely to suffer from heart disease and high blood pressure. This is primarily due to the high omega-3 fatty acid content of fish.

The best fish sources of omega-3 fatty acids are fatty fish like salmon, tuna, trout and sardines, but eating any type of fish will benefit your heart.

Omega-3 fatty acids have been shown to reduce atherosclerosis, ventricular arrhythmias, blood fats, atherosclerotic plaques and blood pressure – all good reasons for eating fish regularly.

9) Venison and ostrich

South Africans are known for their love of meat, and many people who need to follow a low-fat, low-cholesterol diet are horrified by the restrictions on eating red meat.

You can, however, eat moderate portions of venison and ostrich on a low-cholesterol diet, because these meats are low in total fat, saturated fat and cholesterol. Just make sure that you don't add large quantities of fat to the meat during preparation and cooking.

The present boom in our ostrich industry is due to the fact that this meat is so low in cholesterol that it has become a popular item on the menus of health-conscious people all over the world.

10) Omega-3-enriched foods

As mentioned before, the omega-3 fatty acids can play a significant role in helping to reduce the risk of high cholesterol levels. Unfortunately, modern western diets don't contain sufficient omega-3 to meet our needs.

Some food manufacturers have taken this to heart and now produce standard foods that are enriched with omega-3 fatty acids. In South Africa, you can purchase milk, eggs and bread that are enriched with omega-3. You may have to hunt around, but you should be able to find these products in most large supermarkets.

The eggs in particular can make a difference. The rule for egg intake is that anyone with heart problems should not eat more than 4 eggs a week. So make sure that if you eat eggs, they are omega-3 enriched, because the increased levels of omega-3 balance out the high cholesterol content of the eggs.

Top 10 sources of antioxidants

Antioxidants are magic food components. Research shows that these substances could help the body fight cancer, heart disease, Alzheimer's disease and Parkinson's disease by thwarting the action of harmful free radicals.

But which foods are the real antioxidant bombs? Norwegian and US scientists recently compiled an extensive list. In terms of the highest antioxidant content per serving, the winners were:

1. Blackberries 5,75 millimoles per 100g serving

This wonderfully delectable summer fruit came out tops. Blackberries give an antioxidant kick of 5,75 millimoles per serving.

Blackberries are also fat-free, and a source of folic acid and vitamin C, so there's no holding back. Whip them into smoothies, make a wicked fruit coulis to serve with desserts, or simply have them fresh.

You can freeze blackberries and use them all year round. This can be done by coating the berries with a mixture of sugar and ascorbic acid (ask your pharmacist), but it is generally better to freeze lightly boiled berries to which sugar has been added.

2. Walnuts 3,72 millimoles per 100g serving

Nuts are great health foods – they're cholesterol-free, generally low in sodium and a great source of vitamins and minerals. But in terms of antioxidant content, walnuts seem to beat the rest of the nut family with 3,72 millimoles per serving.

Toss these nuts into salads, mix them into muesli, or include them in rice pudding or apple tart.

Just make sure that you have no more than a handful of walnuts per day. If you're overweight, cut this amount to a handful no more than three times per week.

3. Strawberries 3,58 millimoles per 100g serving

Strawberries are sexy, fun and – best of all – so low in calories that you can eat as much as you like without giving your weight a second thought.

These fruits should also form part of your diet for another reason: they're packed with antioxidants and clock in at 3,58 millimoles of these health-boosting components per 100g serving.

There's no need to tell you that strawberries are a great addition to desserts, smoothies, salads, and even cocktails – just make sure you eat them as fresh as possible.

4. Artichokes, cooked 3,56 millimoles per 100g serving

The humble artichoke also made the top-10 list. Apart from the 3,56 millimole/100g antioxidant punch, artichokes are a good source of iron.

These veggies also help to reduce bowel upsets and help to let good bacteria flourish in your gut.

Cook artichokes for 20 minutes with a slice or two of lemon, a bay leaf and salt. The leaves and the heart can then be eaten.

5. Cranberries 3,13 millimoles per 100g serving

The cranberry really is a super-food. Numerous studies have shown that the anti-inflammatory properties of this fruit can help to prevent and treat urinary tract, and possibly other, infections.

One reason why cranberries are so healthy, is because of their high antioxidant content (3,13 millimoles per 100g).

As cranberries are generally too tart to eat fresh, go for the canned varieties and use these in both sweet and savoury dishes.

6. Raspberries 2,87 millimoles per 100g serving

Raspberries have a long history of being used to treat conditions ranging from tonsillitis to stomach aches and also to strengthening the womb in pregnancy.

Now we know that these berries are not only a good source of antioxidants (2,87 millimoles per 100g serving), but are also high in vitamin C.

Ask your grocery store if they stock fresh or frozen raspberries, and use them in fruit salads, deserts or eat them with yoghurt for breakfast.

7. Blueberries 2,68 millimoles per 100g serving

Another berry, this time the blueberry, made the list. This only goes to show that berries really are super foods.

Apart from the high antioxidant content (2,68 millimoles per serving) there is also preliminary evidence that berries can thwart cholesterol and help prevent liver cancer.

Blueberries are not sour and can be eaten raw. This will preserve their vitamin C content.

8. Cloves, ground 2,64 millimoles per 100g serving

Who would have thought that cloves, a great addition to anything from chicken dishes to Christmas mince pies, could have magic health-boosting properties?

Well, this spice made the top 10 antioxidant list – and with good reason. It contains 2,64 millimoles of antioxidants per 100g serving.

While it's more difficult to get your daily antioxidant injection from this spice – simply because we generally use it in small quantities – you should still try to incorporate it in your diet.

9. Grape juice 2,56 millimoles per 100g serving

You already know that a daily glass of wine can kick-start your health. But plain old grape juice seems to be even better – at least when it comes to levels of antioxidants (2,56 millimoles per serving).

Research shows that red grape juice can improve cholesterol levels and inflammatory markers associated with heart disease. This action has been linked to the antioxidant content of the juice.

But be warned: grape juice has a high sugar content and can add quite a few calories to your diet. Don't drink more than one glass of juice, diluted with water, per day.

10. Cranberry juice 2,47 millimoles per 100g serving

As mentioned above, cranberries have strong anti-inflammatory effects and are particularly useful in preventing urinary tract infections.

As fresh, raw cranberries are too tart to eat, cranberry juice is the ideal way to tap the benefits of this fruit.

Try to drink a small glass of cranberry juice every day – especially if you're prone to urinary tract infections. Or combine cranberry juice with iced Rooibos tea for a refreshing summer drink.

Understanding High Blood Pressure or Hypertension

People can have high blood pressure for years without experiencing symptoms or knowing they have it.

The upper or first number in a blood pressure reading is the systolic pressure and the lower or second number is called the diastolic pressure. According to National Heart, Lung, and Blood Institute guidelines:

• Normal blood pressure is below 120/80 mmHg.
• Prehypertension is systolic pressure that's between 120 to 139 or diastolic pressure between 80 and 89.
• Stage 1 hypertension is systolic pressure between 140 to 159 or diastolic pressure between 90 and 99.
• Stage 2 hypertension is systolic pressure higher than 160 or diastolic pressure of 100 or higher.

High Blood Pressure Symptoms

High blood pressure usually doesn't cause any symptoms in the early stages. Symptoms associated with high blood pressure can include:

Causes of High Blood Pressure

In most cases of high blood pressure, the American Heart Association says there is no one identifiable cause. This kind of high blood pressure is called primary hypertension or essential hypertension. Sodium intake. Excessive sodium in the diet can result in fluid retention and high blood pressure, especially in people sensitive to sodium.

• Potassium intake. Stress can raise blood pressure.
• The risk of high blood pressure increases as you get older.
• High blood pressure often runs in families.
• This type of high blood pressure is called secondary hypertension.

Natural Remedies for High Blood Pressure

Lifestyle changes and natural remedies may help to control high blood pressure, but your doctor may also recommend medication to lower high blood pressure.

Coenzyme Q10 (CoQ10).

There is some evidence that the supplement CoQ10 may help to reduce high blood pressure.CoQ10 significantly reduced systolic and diastolic blood pressure(mean reduction 6.1 mm Hg and 2.9 mm Hg respectively).

Garlic

In a meta-analysis of seven randomized controlled trials of garlic supplements, three trials showed a significant reduction in systolic blood pressure and four in diastolic blood pressure. Researchers concluded that garlic powder supplement may be of clinical use in patients with mild high blood pressure.

Garlic can thin the blood (reduce the ability of blood to clot) similar to aspirin. Hawthorn.The herb hawthorn is often used by traditional herbal practitioners for high blood pressure.

Fish oil

Preliminary studies suggest that fish oil may have a modest effect on high blood pressure. Folic acid. It may help to lower high blood pressure in some people, possibly by reducing elevated homocysteine levels.

One small study of 24 cigarette smokers found that four weeks of folic acid supplementation significantly lowered blood pressure.

The 15 Healthiest Foods on the Planet

The following is a "healthy food hot list" consisting of the 29 food that will give you the biggest nutritional bang for you caloric buck, as well as decrease your risk for deadly illnesses like cancer, diabetes and heart disease. Along with each description is a suggestion as to how to incorporate these power-foods into your diet.

Fruits

01. Apricots

The Power: Beta-carotene, which helps prevent free-radical damage and protect the eyes. The body also turns beta-carotene into vitamin A, which may help ward off some cancers, especially of the skin. One apricot has 17 calories, 0 fat, 1 gram of fiber. Snacks on them dried, or if you prefer fresh, buy when still firm; once they soften, they lose nutrients.

02. Avocados

The Power: Oleic acid, an unsaturated fat that helps lower overall cholesterol and raise levels of HDL, plus a good dose of fiber. One slice has 81 calories, 8 grams of fat and 3 grams of fiber. Try a few slices instead of mayonnaise to dress up your next burger.

03. Raspberries

The Power: Ellagic acid, which helps stall cancer-cell growth. These berries are also packed with vitamin C and are high in fiber, which helps prevent high cholesterol and heart disease. A cup has only 60 calories, 1 gram of fat and 8 grams of fiber. Top plain low-fat yogurt or oatmeal (another high fiber food) with fresh berries.

05. Cantaloupe

The Power: Vitamin C (117mg in half a melon, almost twice the recommended daily dose) and beta-carotene - both powerful antioxidants that help protect cells from free-radical damage. Plus, half a melon has 853mg of potassium - almost twice as much as a banana, which helps lower blood pressure. Half a melon has 97 calories, 1 gram of fat and 2 grams of fiber. Cut into cubes and freeze, then blend into an icy smoothie.

06. Cranberry Juice

The Power: Helps fight bladder infections by preventing harmful bacteria from growing. A cup has 144 calories, 0 grams of fat and 0 fiber. Buy 100 percent juice concentrate and use it to spice up your daily H20 without adding sugar.

07. Tomato

The Power: Lycopene, one of the strongest carotenoids, acts as an antioxidant. Research shows that tomatoes may cut the risk of bladder, stomach and colon cancers in half if eaten daily. A tomato has 26 calories, 0 fat and 1 gram of fiber. Drizzle fresh slices with olive oil, because lycopene is best absorbed when eaten with a little fat.

08. Raisins

The Power: These little gems are a great source of iron, which helps the blood transport oxygen and which many women are short on. A half-cup has 218 calories, 0 fat and 3 grams of fiber. Sprinkle raisins on your morning oatmeal or bran cereal - women, consider this especially during your period.

09. Figs

The Power: A good source of potassium and fiber, figs also contain vitamin B6, which is responsible for producing mood-boosting serotonin, lowering cholesterol and preventing water retention. The Pill depletes B6, so if you use this method of birth control, make sure to get extra B6 in your diet. One fig has 37 to 48 calories, 0 fat and 2 grams of fiber. (Cookie lovers - fig bars have around 56 calories, 1 gram of fat and 1 gram of fiber per cookie). Fresh figs are delicious simmered alongside a pork tenderloin and the dried variety make a great portable gym snack.

10. Lemons/Limes

The Power: Limonene, furocoumarins and vitamin C, all of which help prevent cancer. A wedge has 2 calories, 0 fat and 0 fiber. Buy a few of each and squeeze over salads, fish, beans and vegetables for fat free flavor. See also: Beneficial Bytes: Lemons and Limes.

Vegetables

11. Onions

The Power: Quercetin is one of the most powerful flavonoids (natural plant antioxidants). Studies show it helps protect against cancer. A cup (chopped) has 61 calories, 0 fat and 3 grams of fiber. Chop onions for the maximum phytonutrient boost, or if you hate to cry, roast them with a little olive oil and serve with rice or other vegetables.

12. Artichokes

The Power: These odd-looking vegetables contain silymarin, an antioxidant that helps prevent skin cancer, plus fiber to help control cholesterol. One medium artichoke has 60 calories, 0 fat and 7 grams of fiber. Steam over boiling water for 30 to 40 minutes. Squeeze lemon juice on top, then pluck the leaves off with your fingers and use your teeth to scrape off the rich-tasting skin. When you get to the heart, you have found the best part!

13. Ginger

The Power: Gingerols may help reduce queasiness; other compounds may help ward off migraines and arthritis pain by blocking inflammation-causing prostaglandins. A teaspoon of fresh gingerroot has only 1 calorie, 0 fat and 0 fiber. Peel the tough brown skin and slice or grate into a stir-fry.

14. Broccoli

The Power: Indole-3-carbinol and sulforaphane, which help protect against breast cancer. Broccoli also has lots of vitamin C and beta-carotene. One cup (chopped) has 25 calories, 0 fat and 3 grams of fiber. Don't overcook broccoli - instead, microwave or steam lightly to preserve phytonutrients. Squeeze fresh lemon on top for a zesty and taste, added nutrients and some vitamin C.

15. Spinach

The Power: Lutein and zeaxanthin, carotenoids that help fend off macular degeneration, a major cause of blindness in older people. Plus, studies show this green fountain of youth may help reverse some signs of aging. One cup has 7 calories, 0 fat and 1 gram of fiber. Add raw leaves to a salad or sauté with a little olive oil and garlic.
