What are phytochemicals and what is their function?
Phytochemicals (from Greek phyto, meaning “plant”) are chemicals produced by plants through primary or secondary metabolism. They generally have biological activity in the plant host and play a role in plant growth or defense against competitors, pathogens, or predators.
What are phytochemicals and why might they be important?
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.
What are phytochemicals in food?
What are they? Phytochemicals are literally plant (phyto) chemicals: compounds in plants (fruits, vegetables, whole grains, nuts, seeds, and legumes) that contribute to their color, taste, and smell.
What are examples of phytochemicals?
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.
What are two types of phytochemicals?
There are four main categories of phytochemicals: carotenoids, flavonoids, ellagic acid, and allium compounds: Carotenoids such as beta-carotene, lycopene, and lutein protect fat cells, blood, and other bodily fluids from free radicals.
Are all phytochemicals beneficial to the human body?
Phytochemicals give the plant color, aroma and flavor, but when we eat them, they work with other phytochemicals and nutrients to fend off cancer, heart disease, age-related eye disease and more. Some phytochemicals stimulate the immune system. Others slow the growth of cancer cells or prevent DNA damage.
What is the importance of phytochemicals?
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.
How do you determine phytochemicals?
Natural compounds can be determined by using UV-visible spectroscopy . Phenolic compounds including anthocyanins, tannins, polymer dyes, and phenols form complexes with iron that have been detected by the ultraviolet/visible (UV-Vis) spectroscopy .
Which foods are high in phytochemicals?
Foods rich in phytochemicals include apples, apricots, broccoli, Brussels sprouts, cabbage, carrots, cauliflower, garlic, legumes, onions, red peppers, soybeans, sweet potatoes, and tomatoes.
Do eggs have phytochemicals?
Eggs contain the phytochemicals lutein and zeaxanthin, which act as antioxidants and are thought to be protective in the prevention of eye disease.
What is the difference between phytochemicals and nutrients?
Phytochemicals are processed by the body as xenobiotics since it does not distinguish between beneficial, neutral or toxic compounds but only between nutrients and compounds which are not nutrients.
Where can I find phytochemicals?
Sources of phytochemicals
Biflavonoids are found in citrus fruits. Carotenoids are found in dark yellow, orange, and deep green fruits and vegetables such as tomatoes, parsley, oranges, pink grapefruit, and spinach. Flavonoids are found in fruits, vegetables, wine, green tea, onions, apples, kale, and beans.
How do phytochemicals prevent disease?
To get enough phytochemicals, eat large amounts of brightly colored fruits and vegetables, whole grains and cereals, and beans. The kinds of phytochemicals varies by color and type of food. These compounds may act as antioxidants or nutrient protectors. They can help keep cancer-causing agents from forming.
Is caffeine a phytochemical?
