1 Leicestershire Nutrition and Dietetic Services Think about potassium - Asian diet Having a healthy, well balanced diet will help keep you feeling fit and well. Potassium is a naturally occurring mineral found in most foods. Your kidneys control the amount present in your blood, but because these are not functioning properly it is necessary to reduce the amount of potassium in your diet. Abnormal levels of potassium in your blood are not good for your heart. The following guidelines encourage plenty of variety and a regular meal pattern whilst restricting the amount of potassium you eat. Produced by UHL Renal Dietitians August

2 Summary of main points - COOKING METHODS o Potatoes, yam, taro tuber, cassava and many vegetables are high in potassium. o Boiling helps to lower the potassium content before they are added to a curry o Throw the water away after boiling o Do not steam or microwave potatoes, yam, taro tuber, cassava or vegetables - STARCHY FOODS o Chapatti s, rice, pasta, plain naan, noodles and couscous are all low in potassium and may be eaten freely - FRUIT AND VEGETABLES o These foods naturally contain potassium o Keep to 4 portions of fruit and vegetables per day o Choose either potatoes or tomatoes in a curry. Adding both will provide too much potassium. - PROTEIN o Dahl is allowed on a low potassium diet o However, some peas/beans are recommended less frequently due to the potassium they provide - HERBS AND SPICES o Fresh herbs are lower in potassium than dried. Try to use fresh herbs where possible. o Spices may be used as required 2

3 COOKING METHODS Potassium naturally occurs in a wide variety of foods, especially starchy foods and vegetables. The way you cook these foods can affect the potassium content. By boiling starchy foods and vegetables, you can reduce the potassium. It is very important to discard the water after boiling. Do not use the cooking water to make curries or sauces. STARCHY VEGETABLES Potatoes, yam, taro tuber and cassava are particularly high in potassium. The potassium content will be reduced if they are peeled, cut into smaller pieces and then boiled in a big pan of water. The water must then be discarded. Once cooked, they can then be used to make curry but do not make a curry based just on potatoes. Do not steam or use a pressure cooker or microwave to cook the potatoes, yam, taro tuber or cassava. The table below shows which starchy foods can be eaten and how to cook them to reduce their potassium content. Boiled potatoes / taro tuber / Baked starchy vegetables e.g. yam / cassava (discard the jacket potato water) Boiled then fried or roasted Frozen, oven, retail or chip potatoes / yam / taro tuber / shop chips cassava / sweet potato Home made chips (if pre-boiled) Manufactured potato products e.g. potato waffles Mashed potato (not instant) Steamed starchy vegetables Microwaved starchy vegetables Pressure cooked starchy vegetables You may have 100g (4oz) boiled potatoes/yam/taro/cassava or sweet potato per day. 3

4 STARCHY FOODS Low in Potassium Chapattis, puris, plain naan and breads made with chapatti, wheat flour or cornflour Pasta, rice, noodles, couscous, bulgur wheat. Cereals (e.g. Cornflakes, Rice Krispies, porridge oats, Weetabix, Shredded Wheat) High in potassium Peshwari naan Gram / chickpea / bean flour. Products made from this flour such as poppadom s and bhaji's. (Do not add the flour to kudhi or raita) All bran, Bran buds Cereals & cereal bars containing chocolate, dried fruit & nuts Samosas can be eaten. Remember to boil potatoes first if used in the recipe. Khitcherie (rice plus red/green lentils) may be eaten but do not eat with dhal or with a potato based curry. OTHER VEGETABLES Some vegetables are higher in potassium than others, so when you are making curries use vegetables from the choose lists rather than the vegetables in the avoid list. Wherever appropriate, boil vegetables first and throw away the water before proceeding to make a curry. Do not steam or use a pressure cooker or microwave to cook the vegetables. Please note that the canned vegetables will often contain salt and therefore should not be taken too frequently. Alternatively, choose canned vegetables in water with no added salt. Do not add more than half a tin of tomatoes OR 2 x medium sized fresh tomatoes OR 10 x cherry tomatoes to a curry serving four people. Do not have potatoes and tomatoes in the same curry as this will increase the potassium content. 4

5 VEGETABLES All vegetables based on 100g (4oz) serving. You may have 2 servings of vegetables per day: Lower in potassium Asparagus Marrow Aubergine Methi Baby sweetcorn Onions Beansprouts Peas Broccoli Pumpkin Carrots Red/yellow/green peppers Cabbage Runner beans Cauliflower Spring greens Courgette Spring onions Cucumber Swede Curly Kale Tindora (Ivy Gourd) Frozen mixed vegetables Canned ackee Gourd Ash Canned karela Gourd Bottle (Dhoodi) Canned kantola Gourd Round (Tinda) Canned mushrooms Green beans Canned Okra Leeks Canned waterchestnuts Lettuce High in potassium Artichoke Guar Baked beans Karela Beetroot Kantola Brussel Sprouts Okra Callaloo Parsnips Canned or fresh spinach Sweetcorn Drumstick pods/leaves 5

6 FRUIT It is recommended that all patients with renal disease avoid star fruit as it may cause adverse effects. Fruit is quite high in potassium so limit fruit to 1-2 portions daily and use the following list to help choose fruits which are lower in potassium. (Portion sizes are shown in brackets). Lower in potassium Apples (1) Bilberries/blueberries (20) Blackberries (15) Cherries (12) Clementines (2) Cranberries (20) Fig (1 fresh) Gooseberries (12) Grapes (15) Grapefruit (half) Kiwi (1) Lychees (6) Melon - water & galia (1 small slice (100g) Nectarines (1 small) Oranges (1 small) Peaches (1) Pear (1 small) Pineapple (2 small slices) Plums (1) Raspberries (15) Strawberries (8) Tangerines/Satsuma s (1) Tinned fruit (1 small tin drain juice) High in potassium Apricots Avocado Bananas Blackcurrants Custard apple Damsons Dried fruit-all (e.g. Sultanas, prunes, raisins) Elderberries Guava Loganberries Mangoes Melon Cantaloupe Honeydew Papaya Pomegranate Redcurrants Rhubarb Sharon fruit 6

7 PROTEIN Use the list below to guide you as to which peas/beans are suitable for making dhal. Those on the left should be used more frequently. Use those on the right only once per week. If your potassium level is high, you may be asked to avoid the beans on the right. Lower in Potassium Black Gram Blackeye Beans Chick Peas (Chana dhal) Masoor dhal (red lentils) Mung Beans Other whole lentils (green/brown) Red kidney beans canned Higher in Potassium ONCE PER WEEK Aduki beans Pigeon Peas (Toor dhal) Red Kidney Beans dried and boiled Pinto beans Soya beans Guide for portion sizes Allowance up to: Lean meat/poultry 100g (4oz) - main meal / 50g (2oz) - snack meal Fish 150g (6oz) - main meal / 75g (3oz) - snack meal Eggs 5 per week Quorn/Tofu 150g (6oz) per meal If meat, poultry, fish or dhal are taken at a meal, have a maximum of 100g (4oz) vegetable curry If you have no dhal, meat, poultry or fish, you may increase the portion of vegetable curry to 200g (8oz) A small salad 50g (2oz) of the following may be taken with a meal: lettuce, cucumber, onion, peppers, coleslaw Try to avoid cured or salted meats as these are high in salt. DAIRY PRODUCE Milk / Soya Milk Yogurt / Lassi Cheese / Paneer Allowance up to: Per day Tablespoons/day Per week Avoid using condensed milk, evaporated milk, coconut milk, coconut cream and dried milk. 7

8 HERBS & SPICES Fresh herbs are lower in potassium than dried so try to use fresh where possible. Spices including ginger and garlic may be used as required Do not use salt substitutes such as Lo Salt, Selora or Ruthmol as these contain potassium. Use ordinary salt but be careful about the quantity. BEVERAGES If you are on a fluid restriction then all drinks should be included as part of this restriction. Have diet/sugar free drinks if you have diabetes. Lower in Potassium Fizzy drinks (e.g. cola, lemonade) Squashes Tea & herbal teas Spirits (e.g. whisky, gin, brandy) if taken. Higher in Potassium Fruit juice & vegetable juice (including homemade) Blackcurrant drinks Coconut based drinks e.g. coconut milk, coconut water Cocoa & drinking chocolate Malted milk drinks (e.g. Horlicks, Ovaltine) Coffee is higher in potassium - limit to 1 cup per day Limit wine, sherry, port, lager, beer or stout to one small glass per day, if taken. Check with your doctor to see if it is alright for you to drink alcohol. SWEETS/CONFECTIONERY Sweets made with condensed milk, evaporated milk, dried milk, coconut milk, gram flour or ground nuts (e.g. burfi) are high in potassium, similar in fact to chocolate and should be avoided. Use the list below to guide you. Choose sugar-free sweets if you have diabetes. 8

9 Lower in potassium Boiled sweets Pastilles / jellies Chewing gum Jalebi Jelly Gulab jamun Marshmallows Mints High in potassium Chocolate Toffees Liquorice Fudge Carob Burfi Sesame snacks If you have diabetes you may want to consider avoiding these foods as they will cause a rapid rise in your blood glucose levels. You could choose sugar free options if you wish.

10 Note: Many savoury snacks are high in salt so even those lower in potassium should not be included too frequently. MISCELLANEOUS Lower in Potassium Jam Marmalade Honey Syrup Butter Margarine Low fat spreads Higher in Potassium Black treacle Bovril Marmite Vegemite Tomato puree Soups (tinned & packet) Oils Pickles (lime, mango etc.), tomato ketchup and brown sauce are high in potassium limit to 1 tsp only. Pan can be taken if betel nuts are excluded from the recipe or if only a small amount is taken. Remember this is not an exhaustive list and if there are foods you would normally eat which are not mentioned on this sheet please ask the Dietitian if it is all right to carry on eating them. If you have diabetes it is very important that you are also controlling your blood glucose (sugar) levels. Diet can impact on your control; it is the carbohydrate foods/drinks that breakdown into glucose (sugar) when you eat them so will cause a rise in your blood glucose levels. Carbohydrate foods/drinks include: sugars such as full sugar drinks, sweets, sugar honey, fruit and starches such as breads, potatoes, pasta, rice, and foods made with flour. If your blood glucose levels are high you could try reducing your sugar intake and/or your starchy carbohydrate portions.
