Study Notes
Functional Foods
- Defined as foods that provide health benefits beyond their nutritional value.
- Public interest in functional foods is rising, contributing to addressing global hunger and promoting human health.
- Functional foods encompass a broad range, including legumes, oilseeds, vegetables, fish, dairy, beverages, herbs, and spices, each with unique health-promoting properties.
Types of Functional Foods
- Fortified products: Food products fortified with minerals and vitamins, improving food quality and possessing health benefits. Examples include grains with folic acid, fortified juices with vitamin C, and transgenic golden rice with iron and beta-carotene.
- Enriched products: Food items with added nutrients, usually not initially present or present in small quantities. Examples include margarines with stanol esters, sterols, probiotics, and prebiotics, improving properties like cholesterol reduction. Prebiotics and probiotics enhance the gastrointestinal tract environment.
- Altered products: These foods involve removal or replacement of undesirable components with important ones for health benefits. Example: removing fat from grains and replacing it with fiber for reduced-fat products, increasing fibre content.
- Non-altered products: Foods containing naturally occurring nutritional components. Examples include beta-glucan in oats, broccoli with diindolylmethane and selenium for anticancer effects, and fruits like berries, tomatoes, and oranges.
- Enhanced products: Products enhanced through providing different growing conditions, using genetic manipulation in living beings, or by changing animal feed, leading to specific food component enhancements. Example: feeding chickens with specific to create omega-3 enriched eggs; lysine-rich corn.
Bioactive Compounds and Health Benefits
- The presentation details a table relating specific plant-based functional foods with their bioactive compounds and related health benefits. This includes examples like oleuropein (antioxidant) from olives, lycopene (cancer, cardiovascular reduction) from tomatoes, allicin (antimicrobial, cardiovascular reduction) from garlic, etc.
Animal Sources of Functional Foods
- This category outlines animal sources providing bioactive compounds and their related benefits, for example, bioactive peptides from milk protein offering antimicrobial and immunomodulatory effects. Also detailed are fatty acids from fish oil, crucial for brain development, and xylooligosaccharides from yogurt to reduce cholesterol and enhance gastrointestinal health.
Microbes as Functional Food Sources
- Microbes contribute as functional foods too. Lactobacillus and Bifidobacteria contain probiotics offering gastrointestinal benefits, anticarcinogenics, and anti-inflammatory properties. Spirulina microalgae contains numerous vitamins (B vitamins, folic acid) and beta-carotene, while Lactobacillus acidophilus has probiotic properties.
Soybeans, Oilseeds, Vegetables, Dairy and Beverages
- Soybeans, with unique nutritional profiles, contain isoflavones that lower cholesterol, contributing to cardiovascular health. This is beneficial for vegetarians and vegans.
- Flaxseed oil is rich in ALA, an omega-3 fatty acid that lowers blood pressure, acts as a laxative, and promotes healthy skin and hair. It's useful in salad dressings and smoothies.
- Vegetables are excellent sources of dietary fiber, vitamins, minerals, and phytochemicals. Carrots, Psyllium, and leafy greens provide specific benefits. Carrots offer eye health and immune support, Psyllium helps digestion and regulates blood sugar, and leafy greens keep bones healthy and prevent anemia.
- Dairy products, like yogurt, are recognized for their probiotics and calcium and vitamin D content, promoting gut health and preventing osteoporosis. Microencapsulation enhances their viability.
- Green tea is rich in EGCG, a powerful antioxidant protecting from cell damage and supporting weight management and cardiovascular health.
Nutraceuticals
- They are essential food constituents that provide both nutritional and medicinal benefits.
- Nutraceuticals’ benefits stem from active compounds like carotenoids, dietary fibers and collagen hydrolysates.
- They are beneficial to both the cardiovascular and immune systems.
