Top 10 must-eat foods for a healthy diet

10 foods to boost your health Many people believe that the crux of a healthy diet is the exclusion of unhealthy foods. However, a good diet should also incorporate an increased intake of nutritious, health-boosting foods. Here are 10 of the best foods for healthy eaters to stock up on. Nuts Although nuts are high in calories and so should be eaten in moderation, the calories in nuts come mainly from their high levels of monounsaturated fats, which are extremely good for health. Eating foods rich in these fats can help reduce bad cholesterol and lower your risk of heart disease and stroke. As well as their heart benefits, nuts are also a great source of protein and are packed with fibre, antioxidants, fatty acids and vitamins and minerals. It is worth noting that peanuts are actually legumes and have different nutritional properties from tree nuts, but there are many other good options to pick from including Brazil nuts, cashews, walnuts, pecans and pistachios.Oily fish Oily fish - such as salmon, mackerel, sardines and trout - are renowned for their health benefits when eaten in moderation (between two and four portions a week). Not only are they a great source of vitamins and minerals - including immune-boosting vitamins A and D - but they are rich in omega-3 fatty acids. These super healthy unsaturated fatty acids have many health benefits, having been linked to a lowered risk of heart disease, brain damage, stroke, dementia and prostate cancer. Research findings published in the British Journal of Ophthalmology also suggest that omega-3 fatty acids can benefit eye health by halting the progress of age-related macular degeneration. Beetroot Beetroot is one of the latest vegetables to be hailed as a \'superfood\', and looking at its reported health benefits it is easy to see why. Various studies have suggested that drinking beetroot juice can improve stamina when exercising, lower cholesterol and blood pressure, improve heart health and liver function, reduce risk of dementia, and fight against cancer. The versatile vegetable is also a good source of many vitamins and minerals, including vitamin C, which is important for tissue growth and repair, and folate, which helps to reduce the risk of birth defects in unborn babies, as well as helping to prevent anaemia. Onions The onion family (part of the genus Allium) contains many foods that may do wonders for our health including onion, garlic, leeks and chives. Studies have suggested that both onions and garlic can help lower cholesterol, while findings published in the Journal of Nutrition showed that onions could help lower blood pressure.  Onions and garlic also have antiviral and antibacterial properties, so can help to fight against bacteria and illness in the body, while a study by researchers at the King\'s College London and the University of East Anglia found that eating foods from the onion family could help prevent hip osteoarthritis. Dark, leafy greens Dark, leafy greens such as spinach, watercress and kale are automatically associated with healthy eating for many due to the \"eat your greens mantra\" that has been drummed into our heads over the years. However, this faith in the health properties of green veg is well-founded, as these vegetables are bursting with nutrients including iron, calcium, potassium and vitamin C, and packed with health-boosting phytonutrients. Some of the reputed health benefits of eating your greens include lowered blood pressure, improved eye health and a reduced risk of cognitive decline. From : Gulf News.
