By-products of plant food processing as a source of functional compounds — recent developments
TLDR
In this paper, the authors highlight the potential of selected by-products as a source of functional compounds and highlight the benefits of using these byproducts as functional compounds in the context of food processing.Abstract:
There is a rapidly growing body of literature covering the role of plant secondary metabolites in food and their potential effects on human health. Furthermore, consumers are increasingly aware of diet related health problems, therefore demanding natural ingredients which are expected to be safe and health-promoting. By-products of plant food processing represent a major disposal problem for the industry concerned, but they are also promising sources of compounds which may be used because of their favourable technological or nutritional properties. The purpose of this review is to highlight the potential of selected by-products as a source of functional compounds.read more

The effect of vitamin E and beta carotene on the incidence of lung cancer and other cancers in male smokers
O.P. Heinonen,D. Albanes +1 more
TL;DR: No reduction in the incidence of lung cancer among male smokers is found after five to eight years of dietary supplementation with alpha-tocopherol or beta carotene, and this trial raises the possibility that these supplements may actually have harmful as well as beneficial effects.

Antioxidant activity of plant extracts containing phenolic compounds
Marja P Kähkönen,Anu Hopia,Heikki Vuorela,Jussi-Pekka Rauha,Kalevi Pihlaja,Tytti S. Kujala,Marina Heinonen +6 more
TL;DR: High activities were found in tree materials, especially in willow bark, spruce needles, pine bark and cork, and birch phloem, and in some medicinal plants including heather, bog-rosemary, willow herb, and meadowsweet and potato peel and beetroot peel extracts showed strong antioxidant effects.
