There are various ‘Pomi-T’ supplements on the market:
- The long-term effects of these supplements are unknown
- The supplements, should be used for that purpose only ie supplementation. They should not be used in place of treatments or a healthy, balanced diet
The following information is taken from the PCUK website http://prostatecanceruk.org/about-us/news-and-views/2013/6/superfoods
Dr Kate Holmes, Head of Research at Prostate Cancer UK said: “There is increasing evidence showing that men who have a healthy lifestyle, including a balanced diet and regular exercise, have better prostate cancer outcomes than those who do not. At this stage however, we simply do not have enough evidence to suggest that any particular foods or supplements have a significant impact and these should certainly not be substituted for conventional treatments.”
“We would not encourage any man with prostate cancer to start taking Pomi-T food supplements on the basis of this research. Anyone with any concerns about prostate cancer should discuss them with their doctor or call Prostate Cancer UK’s helpline.”
Glycaemic index or GI is used to rank carbohydrate or sugar-containing foods such as bread, pasta, rice, fruit, cereals in terms of the effect they have on blood sugar levels.
Glycaemic index (also known as GI), refers to the speed at which sugar gets into your blood. All starchy foods such as bread, rice, pasta and cereal are made up of lots of sugar molecules. The quicker the sugar gets in to the bloodstream, the quicker it leaves – causing you to feel hungry. When you eat food with a high GI, the sugar from that food gets into your blood quickly causing a quick rise in your blood sugar level. It then leaves quickly so that you end up feeling hungry again quite soon after you’ve eaten. On the other hand, when you eat food with a low GI, the sugar from that food gets into your blood slowly, causing your blood sugar level to rise slowly and plateau. It then leaves again slowly so that you don’t get hungry for some time after you’ve eaten.
It doesn’t necessarily follow that all low GI foods are healthy or that all high GI foods are unhealthy, but it’s something to bear in mind. If you tend to feel hungry soon after eating, check the GI of your meals and see if you can substitute in some lower GI foods to stop this happening.
Some examples of low GI foods are:
- traditional rolled oats
- brown and basmati rice
- beans and pulses
Some examples of high GI foods are:
- tinned fruit in syrup
- mashed potatoes
- white bread and some types of white rice
- fruit juice
- biscuits and sweets
Various factors can determine a food’s GI such as ripeness, fat and protein content and how the food is prepared and cooked. The important thing to note however, is that the GI of a food is for that particular food only and if it is eaten as part of a meal and has anything else added to it (such as beans and cheese on a jacket potato), then the GI of that food can change.
Vitamin D is a vital nutrient and one that many of us lack in the UK, particularly from October to April when we are unable to use the sun to make vitamin D in our skin. Vitamin D is great for our bones and muscles and can be found in the following foods:
- Cod liver oil
- Oily fish such as mackerel, salmon, sardines, fresh tuna, herring, pilchards
- Fortified breakfast cereal
- Fortified dairy products e.g. yoghurts
Some interesting facts:
- Across the UK, surveys have indicated that 1 in 5 people are deficient in vitamin D
- Vitamin D deficiency has been linked to poor bone and muscle health. Various studies have also shown a possible link between vitamin D deficiency and various other health outcomes including cancer however there is not yet enough evidence to confirm this link
- Vitamin D is known as the sunshine vitamin because in the UK between the months of April and October, exposure to UVB rays enable us to make vitamin D in our bodies. However during the winter months and for those people who don’t get much time outside, deficiency can prove to be an issue
- There are very few natural sources of vitamin D within the diet, oily fish and eggs being two of these. In the UK fortified cereals, fat spreads dairy products and some specific foods such as fortified mushrooms have vitamin D added to them. Vitamin D supplements are also available to buy or in certain cases, the GP can prescribe these
- We should be achieving an intake of 10ug/day in the UK according to the most recent guidelines
Some recent research has suggested that certain foods might help to prevent prostate cancer. Tomatoes (a source of lycopene) are one of these foods. Others include soy, green tea, cruciferous veg (eg broccoli and cauliflower) and pomegranate juice. However, the evidence from the research is not substantial. It is likely that any benefit shown could be the effect of generally eating more fruit and vegetables and not just the result of an increased intake of lycopenes or other dietary component. Similarly, there is little evidence that supplements (vitamins or minerals) can reduce the risk of getting cancer or slow down its growth. There is however, robust, scientific evidence that living a more healthy lifestyle, including following a Mediterranean style eating plan and incorporating exercise into your daily routine, can slow down the growth of prostate cancer and reduce the risk of recurrence. It can also help to reduce the risk of treatment-related diseases such as diabetes and heart disease. Don’t be tempted to pin your hopes on one ‘magic’ food or dietary supplement. Adapting to a generally healthier eating pattern and lifestyle is more likely to give control over your prostate cancer and improve your general health and wellbeing.
Blueberries, goji berries, broccoli, dark chocolate, green tea, oily fish, pomegranates, garlic and beetroot have all been in the headlines over recent years and many of them have been termed “superfoods”.
In fact there is no one food that will provide everything that the body needs. ‘Superfood’ is not a legally recognised term. The food does not have to meet any kind of criteria for it to be labelled as “super” – it is often just used as a marketing term and can have an effect on the price of food.
Conversely, there are some foods which have not been labelled as ‘superfoods’ but which do contain key nutrients – oily fish containing essential fatty acids and protein, dairy products containing calcium, wholegrains, fruit and vegetables providing fibre, vitamins and minerals as well as other important micronutrients – and which whilst not being all round ‘superfoods’, do contain nutrients which are beneficial for health.
When it comes to changing your diet, it is worth being aware of all three aspects of dietary intake; quality, quantity and timing. You may have a good idea of which foods are healthiest for you, but how much of them should you eat? It’s really important to get your portion sizes right because eating too much or too little can result in an imbalanced diet and unnecessary weight gain or loss.
The following are guidelines for one portion of different types of food:
- Fresh fruit or vegetables: 80g or a single piece of fruit, a few handfuls of berries or a medium slice of a large fruit.
- Dried fruit: 30g (or a small handful)
- Fruit juice: 150mls (just over ¼ pint)
- Hard cheese e.g. cheddar: 30g (this is the size of a small matchbox)
- Milk: 1/3 of a pint or 190mls
- Yoghurt: a standard pot (125g)
- Starchy foods e.g. cereal, potatoes, pasta and rice: the equivalent of the size of your fist
- Meat and fish: the equivalent to the size of your palm
- Beans and pulses: 3 tablespoons
The number of portions you should be aiming for with regards to the different food groups will depend on whether your goal is to lose weight or not. You won’t necessarily need to restrict yourself to one portion of a particular food type per meal.
If you have been brought up to finish everything on your plate, you could try reducing your overall energy intake by using a smaller plate!
