"There is a lot of confusion out there about which foods are healthy, and which are not.
Here is a list of 20 foods that are generally very unhealthy.
If you want to lose weight and avoid chronic disease, then you shouldn’t eat much of these foods.
In many cases, the best choice is to avoid them completely.
In this article, healthy alternatives are mentioned whenever possible.
1. Sugary Drinks
Added sugar is the single worst ingredient in the modern diet.
However, some sources of sugar are worse than others, and sugary drinks are the absolute worst.
When people drink sugar calories, the brain doesn’t “register” them as food.
For this reason, people don’t automatically compensate by eating less of other foods instead, and end up drastically increasing their total calorie intake (1, 2, 3).
Sugar, when consumed in large amounts, can drive insulin resistance in the body and is strongly linked to non-alcoholic fatty liver disease. It is also associated with various serious diseases, including type 2 diabetes and heart disease ( 4, 5, 6).
Sugary drinks are also THE most fattening aspect of the modern diet, and drinking them in large amounts can drive fat gain and obesity ( 7, 8, 9).
Alternatives: Drink water, soda water, coffee or tea instead. Adding a slice of lemon to water or soda water can add some taste if you don’t like it plain.
2. Most Pizzas
This is not surprising, given that it tastes awesome and is incredibly convenient to eat.
The problem is that most commercially prepared pizzas are made with seriously unhealthy ingredients.
The dough is made from highly refined wheat flour, and the meats on them are usually processed. Pizza is also extremely high in calories.
Alternatives: Some pizza places use healthier ingredients. Homemade pizzas can also be very healthy, as long as you choose wholesome ingredients.
3. White Bread
Bread is generally made from wheat, which contains the protein gluten.
For this reason, all wheat-based breads are a bad idea for people who have celiac disease or gluten sensitivity.
However, most commercial breads are unhealthy, even for people who do tolerate gluten.
This is because the great majority of them are made from refined wheat, which is low in essential nutrients (empty calories) and leads 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 definitely better (or “less bad”) than white bread.
If you have problems with gluten or carbs, then here are 15 recipes for breads that are both gluten-free and low in carbs.
4. Most Fruit Juices
Fruit juice is often assumed to be healthy, but this is a mistake.
Many fruit juices are actually little more than fruit-flavored sugar water.
It is true that the juice contains some antioxidants and vitamin C, but this must be weighed against the large amount of liquid sugar.
In fact, fruit juice contains just as much sugar as a sugary drink like Coke or Pepsi, and sometimes even more ( 11 ).
Alternatives: There are some fruit juices that have been shown to have health benefits despite the sugar content, such as pomegrenate juice and blueberry juice.
However, these should be considered as supplements, not something you drink every day to quench thirst. Drink water instead.
5. Industrial Vegetable Oils
In the last 100 years or so, people have increased their consumption of added fats.
However, this is entirely explained by a drastic increase in the consumption of refined vegetable oils, such as soybean oil, corn oil, cottonseed oil and canola oil.
These oils are very high in omega-6 fatty acids, which humans never consumed in such large amounts before.
There are many serious concerns with these oils. They are highly sensitive to oxidation and cause increased oxidative stress in the body. They have also been linked to increased risk of cancer ( 12, 13, 14, 15, 16, 17, 18, 19 ).
Alternatives: Use healthier fats like coconut oil, butter, extra virgin olive oil or avocado oil instead."
