Planning a heart healthy diet


General Principles:
1.       Preferred diet is lacto-vegetarian
2.       Low in sodium, sugar, and calories
3.       Natural foods rich in high-quality fibre and nutrients - preferably organic  foods
4.       Emphasis on whole grains, seeds (including nuts), fresh fruits, and vegetables
5.       Foods to be eliminated from the diet include white-flour products, sweets, canned foods, syrupy juices, soft drinks, squashes, hard-fats from animal sources – butter and cream in particular
6.       Yoghurt/curds, and skimmed milk is OK and can be consumed within prescribed limits
7.       Tea and Coffee should be severely limited (1 cup a day max) or avoided totally. Those addicted to these beverages should be weaned away gradually
8.       Garlic and onions are excellent for the heart
9.       Nuts in general and walnuts, almonds, pistachios, pecans, and peanuts in particular, are good for the heart as they reduce LDL and help raise the levels of HDL. However do not consume more than a handful a day. You could even use them to garnish your oat porridge. Importantly, all nuts that you consume should be unsalted.
10.   Among grains Oats and barley are the gold standard as they contain soluble fibre. Other foods that contain soluble fibre include apples, pears, kidney beans, and prunes
11.   Among oils, olive oil and sesame (gingely) oil are heart healthy. Cold-pressed oils are preferable to heat-processed oils. Again oil should be limited to about 2 tablespoons a day
12.   Among fruits - fresh grapes, pineapples, oranges, apples, custard apples, pomegranates, and pears are heart healthy
13.   Tender-coconut water is a good heart tonic
14.   Amla (Indian gooseberry) is an excellent heart tonic
15.   Vegetables in general are rich in fibre and should be part of a heart healthy diet
16.   Important thumb rule: 75-85% of a day’s food should come from whole-grains, vegetables, and fruits
Table 1: Foods to be avoided or severely limited
Food substance
Remarks
What it means
Sodium (Salt)
Limit intake to < 1,500 mg per day – roughly 1 teaspoon or lesser
1.       No “added” salt
2.       No biscuits, pastries, cakes, canned foods, savouries, chips, dips, sauces, ketchups, and processed foods
3.       Check food labels for sodium content – several processed, commercially available food substances contain hidden salt
Sugar
Cut recommended sugar intake by 50-60% Recommended max sugar intake is 6 teaspoons/day, so aim for 2 teaspoons of sugar a day
1.       No chocolates, sweets, toffees, and added refined sugar
2.       Substitute honey for sugar (again limit to no more than teaspoon/day) – honey is better than refined sugar
Drugs
Avoid all NSAIDS* (In general and particularly in Heart failure)
1.       Paracetamol/Acetaminophen, Ibuprofen should be avoided by heart patients. If you have a headache use a balm or if you must consume a pain-killer, choose aspirin
Trans fats
Avoid completely
1.       Hydrogenated fats (Vanaspathi/Dalda) to be avoided completely
2.       Packaged cookies, crackers, commercially prepared fried foods, chips, savouries, sweetmeats, potato crispies, finger-chips

*Non-steroidal anti-inflammatory drugs

Table 2: Natural foods that are "heart-healthy"
Food substance
Benefits
Grapes and grape juice
1.       Contain resveratrol known to preserve heart muscle flexibility
2.       Reduces heart pain and palpitations
3.       Helpful in reducing platelet aggregation and clots
4.       Oxidises LDL (bad cholesterol)
Apples
1.       Contain quercetin that is a natural anti-inflammatory which helps prevent blood clots
2.        Rich in soluble fibre
Amla (Indian gooseberry)
1.       Richest natural source of Vitamin-C
2.       Heart tonic that tones up the heart muscle
Tomatoes
1.       Contain Lycopene a potent antioxidant and free radical scavenger
2.       Promotes heart health
Almonds, walnuts, pistachios, pecans
1.       Contain “good-fat” (monounsaturated and polyunsaturated fats)
2.       Enhance HDL (good cholesterol), reduce LDL
3.       Reduce inflammation and blood clots
Onions and garlic
1.       Reduces LDL
2.       Onions like apples contain quercetin that is a natural anti-inflammatory which helps prevent blood clots
3.       Allicin in garlic is broken down into sulphur compounds which then react with RBC in blood to produce hydrogen sulphide which helps relax the blood vessels, thus keeping blood flowing freely in arteries
Pineapples
1.       Rich source of vitamin-C
2.       Improves blood flow to heart
3.       Prevents pain due to angina
4.       Beneficial in patients with ischaemic heart disease
Pomegranates
1.       Rich in polyphenol antioxidants
2.       Reduce LDL, enhance HDL

Caution: Pomegranate juice can (in some patients) interact with certain medicines such as warfarin, ACE-inhibitors – check with your doctor before including it in your diet
Oranges
1.       Rich source of Vitamin-C and phytochemicals
2.       Prevents LDL and enhances HDL
3.       The phytochemical Hesperidin, a flavanone, improves blood vessel function and also lowers high blood pressure level
