Are phytochemicals lost when processed?
Depending on the degree of processing, many nutrients can be destroyed or removed. Peeling outer layers of fruits, vegetables, and whole grains may remove plant nutrients (phytochemicals) and fiber. Heating or drying foods can destroy certain vitamins and minerals.
What foods are rich in phytochemicals?
Foods high in phytochemicals include the following:
- Broccoli.
- Berries.
- Soynuts.
- Pears.
- Turnips.
- Celery.

What is the importance of phytochemicals in the food industry?
Phytochemicals have a strong effect on control and prevention of natural spoilage processes and growth of microorganisms, including pathogens causing food safety issues.
How do the phytochemicals present in various foods?
Phytochemicals are compounds that are produced by plants (“phyto” means “plant”). They are found in fruits, vegetables, grains, beans, and other plants. Some of these phytochemicals are believed to protect cells from damage that could lead to cancer.
Are phytonutrients destroyed when cooked?
Boiling. There’s bad news if you’re a fan of boiling your vegetables. Boiling causes the highest loss of antioxidants in vegetables, according to a report in the journal Preventative Nutrition and Food Science that was published in 2012. Boiling may reduce antioxidant content by as much as 60 percent.
What is bad about processed foods?
Heavily processed foods often include unhealthy levels of added sugar, sodium and fat. These ingredients make the food we eat taste better, but too much of them leads to serious health issues like obesity, heart disease, high blood pressure and diabetes. Lacking in nutritional value.
What are examples of phytochemicals?
A few examples of well-known phytochemicals are the flavonoids, phenolic acids, isoflavones, curcumin, isothiocyanates, and carotenoids. The many phytochemicals in common plant foods, herbs, and spices represent a broad range of chemical compounds.
What are the different types of phytochemicals?
Generally, phytochemicals have been classified into six major categories based on their chemical structures and characteristics. These categories include carbohydrate, lipids, phenolics, terpenoids and alkaloids, and other nitrogen-containing compounds (Figure 1; Harborne and Baxter, 1993; Campos-Vega and Oomah, 2013).
What benefits do phytochemicals provide?

How do phytochemicals work?
Phytochemicals are naturally occurring compounds in plant foods such as fruits, vegetables, whole grains, beans, nuts and seeds. In laboratory studies, many phytochemicals act as antioxidants, neutralizing free radicals and removing their power to create damage.
Does cooking destroy phytochemicals?
Are the phytochemicals in fruits and vegetables destroyed in cooking? Generally not. The main phytochemicals in soybeans, for example, are not destroyed by heat, and the lycopene in tomatoes appears to become more available to the body after heating.
Are phytochemicals destroyed by heat?
The main cause of phytochemical loss in food is high temperature degradation, however, for lipophilic ones such as carotenoids found in tomatoes they might remain stable or increase in content upon application of high temperature [11,12].
What do processed foods contain?
Highly processed, or ultra-processed, foods contain few or no minimally processed or unprocessed ingredients and tend to be higher in calories, salt, fat, and added sugars. Plus, they often contain additives such as flavor enhancers and thickeners.
What are the benefits of processed foods?
Food processing allows key nutrients to be sealed in right after harvesting. This in turn means that individuals get more nutrients from the food they eat. Processed foods can also be fortified with additional nutrients such as vitamins, minerals, and fiber to boost the health profile of foods.
What are two types of phytochemicals?
There are three major groups of phytochemicals:
- Polyphenols – subcategorised as the flavonoids, phenolic acids and other non-flavonoid polyphenols.
- Terpenoids – subcategorised as the carotenoids and non-carotenoid terpenoids.
- Thiols – includes the glucosinolates, allylic sulfides and non-sulfur containing indoles.
Are phytochemicals functional foods?
Functional foods may contain significant levels of biologically active components that impart health benefits when consumed in optimal serving sizes. Phytochemicals are components of plants that convey healthful properties beyond their use as macronutrients or micronutrients.
What are the 2 main types of phytochemicals?
Phytochemicals are natural chemicals in plant-based foods, particularly colorful ones. The major phytochemicals are polyphenols and carotenoids. Specific phytochemicals include lutein, quercetin, anthocyanins, lycopene, curcumin, resveratrol, cinnamic acid, and capsaicin.
What are the 3 phytochemicals?

What is the best way to get phytochemicals in the diet?
The only way to increase the intake of phytochemicals is to eat more plant foods. Here are some tips for incorporating more plant foods in your diet: Make a conscious effort to eat at least five portions of fruits and vegetables every day. Use ketchup on your burgers instead of mayonnaise.
What is an example of phytochemical?
Phytochemicals are a wide variety of nonnutritive chemical compounds found in plant foods, which may have health effects. A few examples of well-known phytochemicals are the flavonoids, phenolic acids, isoflavones, curcumin, isothiocyanates, and carotenoids.
