Regularly consuming processed meats, sugary drinks, deep-fried foods and highly processed snacks may increase the risk of long-term health problems.
Adults should also limit excessive salt, added sugar, refined carbohydrates and alcohol to support heart health, blood sugar control and overall well-being.
Turning 30 does not mean giving up favourite foods; it is an opportunity to develop healthier eating habits by choosing more fruits, vegetables, whole grains, nuts and lean proteins.
Turning 30 does not mean you have to give up your favourite meals, but it can be a good time to pay closer attention to your eating habits.
What you eat over the years can influence your risk of developing health conditions such as high blood pressure, heart disease, type 2 diabetes and certain cancers.
While no particular food becomes harmful simply because you turn 30, regularly consuming foods high in added sugar, salt and unhealthy fats can affect your long-term health.
Here are eight foods and drinks worth limiting as you get older.
1. Processed meats
Sausages, bacon, ham, hot dogs and corned beef are examples of processed meats. They are often high in salt, and regular consumption is associated with an increased risk of colorectal cancer.
2. Sugary drinks
Soft drinks, sweetened fruit juices, energy drinks and other sugar-sweetened beverages can add substantial amounts of sugar to your diet.
Frequent consumption can contribute to excess calorie intake, weight gain and an increased risk of type 2 diabetes. Choose water more often and limit drinks with added sugar.
3. Deep-fried foods
Regularly eating foods such as fried chicken, chips, fried dough and other deep-fried meals can increase your intake of calories and unhealthy fats, particularly when prepared with oils high in saturated or trans fats.
Try eating fried foods less frequently and choose alternatives such as boiled, grilled, baked or steamed meals more often.
4. Highly processed snacks
Packaged biscuits, crisps, sweets and some instant snack foods may contain high amounts of salt, added sugar and unhealthy fats.
Eating these foods frequently can make it harder to maintain a balanced diet. Instead, consider healthier snacks such as fruit, nuts and plain yoghurt.
5. Foods high in salt
Excessive salt consumption can increase blood pressure, which raises the risk of heart disease and stroke.
Some instant noodles, processed meats, salted snacks, seasoning powders and packaged sauces can contain considerable amounts of sodium.
The WHO recommends that adults consume less than five grams of salt daily, equivalent to approximately one teaspoon from all food sources combined.
6. Foods high in added sugar
Cakes, pastries, sweets, sweetened breakfast cereals and desserts can contribute to excessive sugar intake when eaten regularly.
Too much added sugar can contribute to weight gain and increase the risk of tooth decay and other health problems.
The WHO recommends keeping free sugars below 10 per cent of total daily energy intake, with further benefits possible when consumption is reduced to five per cent or less.
7. Refined carbohydrates
White bread, white rice, pastries and other refined grain products contain less fibre than their whole-grain alternatives because some parts of the grain are removed during processing.
Eating too many low-fibre refined carbohydrates may make it harder to maintain a balanced diet and manage blood sugar levels.
You do not need to eliminate them completely. Where possible, include whole grains such as brown rice, oats, millet and whole-wheat bread in your meals.

8. Alcohol
Regular or excessive alcohol consumption can increase the risk of several health conditions, including liver disease, high blood pressure and certain cancers.
Reducing alcohol intake or avoiding it altogether can help lower these risks. Alcohol consumption is not necessary for good health.
What should you eat more of after 30?
Instead of focusing only on foods to avoid, aim to eat a variety of nutritious foods, including fruits, vegetables, beans, nuts, whole grains and fish.
Choose healthier sources of fat, drink enough water and maintain regular physical activity.
Most importantly, remember that healthy eating is not about completely avoiding your favourite foods. It is about making balanced choices and developing habits that support your health over time.
