Eating a healthy diet has a myriad of health benefits including giving the body energy, growth and repair, weight management, strong bones and teeth, and reducing your risk of type 2 diabetes and heart disease.According to one expert, making good food choices is key to living a long life. Peak performance coach and founder of Longevity & Lifestyle, Claudia von Boeselager, shared the breakfast “power foods” that can “unlock your longevity”.Taking to YouTube, the expert advised people to incorporate eggs into their first meal of the day.She said: “Not only are you getting so much protein, you are getting vitamin A, B12, folate, vitamin D, vitamin E, choline, healthy fats, [good] cholesterol – you name it.”Eggs are packed with vitamin A, B12, folate, vitamin D, vitamin E, choline, healthy fats and good cholesterolGETTY IMAGESYears ago, eating just two eggs per week was recommended due to their high levels of dietary cholesterol. However, more recent research has found that dietary cholesterol had little influence on blood levels of total and “bad” cholesterol, Harvard Medical School assured.Experts stated: “While recent studies still don’t offer a consistent answer, the average healthy person likely suffers no harm from eating up to seven eggs per week. In fact, eggs are a nutritious food. They are relatively low in calories and saturated fat, and rich in protein, vitamins, and minerals. “They also contain nutrients, such as lutein and zeaxanthin, which are good for the eyes, and choline, which helps support the brain and nervous system.”Longevity expert Claudia also advised stocking up on “healthy greens” – namely avocados. The longevity guru pointed to a study that followed over 110,000 men and women over 30 years.The study found that “a higher intake of avocado was associated with a lower risk of cardiovascular disease and coronary heart disease”.The study, published in the Journal of the American Heart Association, suggested that eating two servings of avocado per week could be beneficial.Its conclusion reads: “Higher avocado intake was associated with lower risk of cardiovascular disease and coronary heart disease in two large prospective cohorts of US men and women.”The replacement of certain fat‐containing foods with avocado could lead to a lower risk of cardiovascular disease.”In addition to eating more eggs and healthy greens such as avocado at breakfast time, the longevity expert advised staying adequately hydrated in the mornings.She said: “It’s not food but it’s super important – hydration, water. You need to get enough water in your body and start your day by drinking at least two glasses of filtered water.” Claudia enjoys hers with a slice of lemon.LATEST DEVELOPMENTSHigher avocado intake could lower your risk of cardiovascular disease and coronary heart diseasePA IMAGESFollowing a healthy diet is a great way to increase longevity. One doctor suggested that following a plant-based diet high in two specific foods may be “key” to living longer.Eating a plant-based diet does not mean avoiding meat and animal products entirely. It simply means prioritising plant-based foods.Harvard Medical School explained: “It doesn’t mean that you are vegetarian or vegan and never eat meat or dairy. Rather, you are proportionately choosing more of your foods from plant sources.”This means more fruits and vegetables, nuts, seeds, oils, whole grains, legumes and beans.
