With the European Congress on Obesity revealing that 4 in 10 cancer cases are linked to obesity, and the NHS sharing that the health implications of obesity are estimated to cost up to £100 billion per year, it’s clear that it is more important than ever to look after your health.
Are we now tired of fad diets that promise (and fail) to deliver? Let’s look at the link between longevity and diet and how you can shift your perspective on health and food.
“Eating a diet that’s high in saturated fat can lead to carrying excess weight and high cholesterol,” says Dr Paul van der Westhuizen, Men’s Health Lead at home blood testing service Medichecks.
“These risk factors impact your metabolic health and increase your risk of developing metabolic syndrome. Metabolic syndrome affects around one in four adults in the UK, and can increase your risk of coronary heart disease, diabetes, and stroke.
“What you eat can directly impact your health and disease risk. For instance, people living in Blue Zones (areas with large populations of centenarians) generally eat mostly plant-based diets. They consume little to no ultra-processed foods and red meats.
“But it isn’t only what you eat that’s important. How and when you eat may be just as crucial. Eating too close to bedtime (when melatonin rises) is associated with increased body fat and obesity, increasing blood sugar levels the next day after meals, and greater risk of poor cardiometabolic health.”
Six eating habits for longevity
1. Focus on nourishing your body for your future
“It’s common to interpret diet to mean restriction. But your diet shouldn’t be a sorry affair. Eating delicious, nourishing food fuels your body’s needs and activity levels and can help you live longer in better health.
“The first step to starting a diet to support longevity is to visualise how you want to live in old age. Honestly, what would you like to be able to do in your 80s, 90s, and at 100+?
These goals could link to health, fitness, family, community, independence, fun, or creativity. You might aim to visit your favourite gallery, meet grandchildren (or great-grandchildren), or to be able to make yourself a cup of tea. And you’re more likely to get there if you stay in good health for longer.
“Instead of crash dieting to lose weight for a short-term goal, shift your perspective. You’re now nourishing your body to increase your chance of being active and enjoying life well into your 90s.”
2. Avoid ultra-processed foods advertised as low-fat
“We’re well aware that a diet of ultra-processed foods isn’t good for our long-term health, but ultra-processed foods can be disguised as healthy, usually with a low-fat or high-protein label.
“Foods labelled as low-fat almost certainly go through a process to remove fat from them. Sugars, flavourings, whey proteins, and pectin usually replace this natural fat content.
The removed fat is also rich in micronutrients and probiotic bacteria, which have positive effects on overall health.
“In the 80s, we believed that low fat equalled healthy. We now know we need to focus on the right kinds of fats and the total makeup of nutrients.
Absorbing nutrients is a complex process, but marketing tactics can cause more confusion.”
3. Eat like a mediterranean
“For longevity, the Mediterranean diet remains one of the gold standards. This is more of a way of eating, rather than a strict diet.
The Mediterranean diet includes a large quantity of olive oil, vegetables, and nuts, and avoids processed meats.”
A Mediterranean diet is a high intake of:
- Fruits and vegetables
- Whole grains
- Pulses
- Healthy fats – nuts, olive oil, avocado
- Herbs and spices
A moderate intake of:
- Dairy
- Eggs
- Seafoods (a few times a week)
Limited intake of:
- Meats (more white meat than red meat)
- Sweets
4. Cut out sugar-sweetened drinks
“Drinks are an important component of your diet. Sugar-sweetened beverages and artificially sweetened beverages can increase the risk of cardiovascular disease and premature death.
Coffee, tea, and plain water are healthier options (though you should watch your caffeine intake).
“Green tea in particular has the most health benefits, linked to lower risk of heart disease, cancer, type 2 diabetes, Alzheimer’s, and importantly: obesity.
“As well as drinking your green tea, you can add it to smoothies, oatmeal, or overnight oats if you prefer.
The powdered form of green tea is matcha. If you have a more savoury palate, try adding matcha powder to soups, stews, sauces, and marinades.”
5. Slow down your eating and eat until you are 80% full
“Eat until you’re satisfied and not hungry, but don’t eat to the point that you’re full or stuffed.
Japan has one of the lowest rates of illness from heart disease, cancer, and stroke. One of their mottos is hara hachi bu, meaning to eat until you’re 80% full.
“One way to avoid overeating is to look at your eating pattern. Intermittent fasting is a popular way to restrict the time that you’re eating.
This is thought to allow your body more time to digest your food and not overconsume.
“More evidence is also emerging on how eating pace affects satiation. The study of obesity showed that overweight men and women took in fewer calories when they slowed their normal eating pace.”
6. Make meal times sociable
“Now you understand your health risks, you’re focusing on eating plenty of fresh and whole foods, and are wise to marketing traps. Turn your focus towards where and when you eat. Are meals enjoyable?
“Many Mediterranean countries and people living in Blue Zones make meals a social occasion.
They bring friends and family together. Meals are an enjoyable experience – from chatting over making bread to sharing food around the table.
“Now, imagine where you eat your meals and snacks. Does it evoke the same feelings? Where and when you eat is arguably as important as what you eat.”
Is there one diet for longevity?
“Health and longevity isn’t something that can be achieved with one magic ingredient. Living a longer life involves looking at each part of your wellbeing, from your nutrition to how you move and your social connections.
“Short-term thinking is out. Focus on nourishing your body to reduce your risk of long-term disease.
This long-term thinking can help to increase your chance of extending your life expectancy and living longer in good health.”
