What substances in plants help protect against chronic diseases?
Antioxidant phytochemicals can be found in many foods and medicinal plants, and play an important role in the prevention and treatment of chronic diseases caused by oxidative stress.
What chemical compounds are found in plant based diets that are important for preventing chronic diseases?
These flavonoids, stilbenes, and curcuminoids have a positive impact on cardiovascular disease, cancer, and neurodegeneration. These nutrients are often enzymatic cofactors and may have both additive and synergistic pleiotropic effects that reduce risk of chronic disease.
What is the name for the natural chemicals found in plants that have health benefits?
phytonutrients
Plant foods contain thousands of natural chemicals. These are called phytonutrients or phytochemicals. “Phyto” refers to the Greek word for plant.
What are 5 phytochemicals?
Among the phytochemicals mentioned as potentially providing health benefits are polyphenols, flavonoids, isoflavonoids, anthocyanidins, phytoestrogens, terpenoids, carotenoids, limonoids, phytosterols, glucosinolates, and fibers.
What are plant chemicals?
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.
How do phytochemicals prevent diseases?
Phytochemical supplementation can benefit human health through supplying specific antioxidative/bioactive compounds which have preventive role in several diseases. Flavonoids are the most common phytochemicals that provide antimicrobial, antioxidant, anticancer, anti-inflammatory, and wound-healing activities.
What are phytochemicals and antioxidant?
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.
What does the DASH diet prevent?
DASH stands for Dietary Approaches to Stop Hypertension. The DASH diet is a healthy-eating plan designed to help treat or prevent high blood pressure (hypertension). The DASH diet includes foods that are rich in potassium, calcium and magnesium. These nutrients help control blood pressure.
What antioxidant means?
Listen to pronunciation. (AN-tee-OK-sih-dent) A substance that protects cells from the damage caused by free radicals (unstable molecules made by the process of oxidation during normal metabolism). Free radicals may play a part in cancer, heart disease, stroke, and other diseases of aging.
What are three examples of chemicals from plants that humans use?
Modern medicines derived from plants include aspirin, taxol, morphine, quinine, reserpine, colchicine, digitalis and vincristine.
What chemicals help plants grow?
Nitrogen, phosphorous, potassium, sulfur, calcium, magnesium and sodium are also needed for plant growth. In addition, plants need very small amounts (trace elements) of boron, copperiron, cobalt, manganese, molybdenum, chlorine, iodine, selenium and zinc for healthy growth.
How do phytochemicals protect plants?
Phytochemicals are a plant’s way of protecting itself. They help shield tender buds and sprouts from predators, the elements, and pollution. These protective compounds are passed along to us when we eat plant foods.
How to promote the use of medicinal plants in disease prevention?
In promoting the use of medicinal plants in disease prevention, the whole-population strategy will have the global community as the target, whereas the high-risk strategy may focus on rural communities, especially in the developing countries.
What plants have anti-inflammatory properties?
Whole plant Phenols, Alkaloids Antimicrobial, anti-inflammatory, anti-allergic properties. Kokwaro (1993) 13 Kigelia Africana (Lam.) Benth Bignoniaceae Sausage tree Pandoro (Yoruba) Ishi (Igbo), Rahaina, nonon giwa (Hausa) Bark, Seed. Naphthoquinones, Iridoids, Anti-malaria 14 Adansonia digitata L.
Can medicinal plants be used as food additives?
Some medicinal plants possess more potent antioxidant activity than common dietary plants (Cai et al., 2004). Therefore, their extract, if not toxic, can serve as food additive and can be used for disease prevention (Liu, 2003; Liu et al., 2008).
Why choose phytochemicals from medicinal plants?
Phytochemicals from medicinal plants can provide a better and safer alternative to synthetic molecules. Many phytochemicals have been identified that cure the human body from a number of diseases.
