It's easy to get confused about which foods are healthy and which aren't.
You generally want to avoid certain foods if you want to lose weight and prevent chronic illnesses.
In this article, healthy alternatives are mentioned whenever possible.
Here are 20 foods that are generally unhealthy — although most people can eat them in moderation on special occasions without any permanent damage to their health.
1. Sugary Drinks
Added sugar is one of the worst ingredients in the modern diet.
However, some sources of sugar are worse than others, and sugary drinks are particularly harmful.
When you drink liquid calories, your brain doesn't appear to register them as food. Thus, you may end up drastically increasing your total calorie intake (1Trusted Source, 2Trusted Source, 3Trusted Source).
When consumed in large amounts, sugar can drive insulin resistance and is strongly linked to non-alcoholic fatty liver disease. It's also associated with various serious conditions, including type 2 diabetes and heart disease (4Trusted Source, 5Trusted Source, 6Trusted Source).
Some people believe that sugary drinks are the most fattening aspect of the modern diet — and drinking them in large amounts can drive fat gain and obesity (7Trusted Source, 8, 9Trusted Source).
Alternatives
Drink water, soda water, coffee, or tea instead. Adding a slice of lemon to water or soda water can provide a burst of flavor.
2. Most Pizzas
Pizza is one of the world's most popular junk foods.
Most commercial pizzas are made with unhealthy ingredients, including highly refined dough and heavily processed meat. Pizza also tends to be extremely high in calories.
Alternatives
Some restaurants offer healthier ingredients. Homemade pizzas can also be very healthy, as long as you choose wholesome ingredients.
3. White Bread
Most commercial breads are unhealthy if eaten in large amounts, as they're made from refined wheat, which is low in fiber and essential nutrients and may lead to rapid spikes in blood sugar (10).
Alternatives
For people who can tolerate gluten, Ezekiel bread is an excellent choice. Whole-grain bread is also healthier than white bread.

4. Most Fruit Juices
Fruit juice is often assumed to be healthy.
While juice contains some antioxidants and vitamin C, it also packs high amounts of liquid sugar.
In fact, fruit juice harbors just as much sugar as sugary drinks like Coke or Pepsi — and sometimes even more (11Trusted Source).
Alternatives
Some fruit juices have been shown to have health benefits despite their sugar content, such as pomegranate and blueberry juices.
However, these should be considered occasional supplements, not an everyday part of your diet.
5. Sweetened Breakfast Cereals
Breakfast cereals are processed cereal grains, such as wheat, oats, rice, and corn.
They're especially popular among children and frequently eaten with milk.
To make them more palatable, the grains are roasted, shredded, pulped, rolled, or flaked. They're generally high in added sugar.
The main downside of most breakfast cereals is their high added sugar content. Some are so sweet that they could even be compared to candy.
Alternatives
Choose breakfast cereals that are high in fiber and low in added sugar. Even better, make your own oat porridge from scratch.
6. Fried, Grilled or Broiled Food
Frying, grilling, and broiling are among the unhealthiest cooking methods.
Foods cooked in these ways are often highly palatable and calorie-dense. Several types of unhealthy chemical compounds also form when food is cooked under high heat.
These include acrylamides, acrolein, heterocyclic amines, oxysterols, polycyclic aromatic hydrocarbons (PAHs), and advanced glycation end products (AGEs) (12Trusted Source, 13Trusted Source, 14Trusted Source, 15Trusted Source, 16Trusted Source, 17Trusted Source).
Many chemicals formed during high-heat cooking have been linked to an increased risk of cancer and heart disease (18Trusted Source, 19, 20Trusted Source).
Alternatives
To improve your health, choose milder and healthier cooking methods, such as boiling, stewing, blanching, and steaming.
7. Pastries, Cookies and Cakes
Most pastries, cookies, and cakes are unhealthy if eaten in excess.
Packaged versions are generally made with refined sugar, refined wheat flour, and added fats. Shortening, which may be high in unhealthy trans fats, is sometimes added.
These treats might be tasty, but they have almost no essential nutrients, copious calories, and many preservatives.
Alternatives
If you can't stay away from dessert, spring for Greek yogurt, fresh fruit, or dark chocolate
