But the definition, and the way scientists use each term, is a little loose. As a general rule, a peptide contains two or more amino acids. And just to make it a little more complicated, you will often hear scientists refer to polypeptides – a chain of 10 or more amino acids.
Dr Mark Blaskovich from the Institute for Molecular Bioscience (IMB) at The University of Queensland in Australia says approximately 50-100 amino acids is the cut-off between a peptide and a protein. But most peptides found in the human body are much shorter than that – chains of around 20 amino acids.The term antiaging can incorporate a broad range of nutraceutical possibilities. For the purpose of this article, let’s define antiaging nutraceuticals as those nutracentical ingredients that help to address health and wellness issues associated with aging. In this context, that would potentially include nutraceuticals that can positively impact the aging process itself as well as those that positively impact aspects of human physiology that tend to decline with age, such as joint health and cognitive health. Ahead, we touch on a few promising contenders.
The benefits of organic food
How your food is grown or raised can have a major impact on your mental and emotional health as well as the environment. Organic foods often have more beneficial nutrients, such as antioxidants, than their conventionally-grown counterparts and people with allergies to foods, chemicals, or preservatives may find their symptoms lessen or go away when they eat organic fruit and vegetable powder.
Organic produce contains fewer pesticides. Chemicals such as synthetic fungicides, herbicides, and insecticides are widely used in conventional agriculture and residues remain on (and in) the food we eat.
Organic food is often fresher because it doesn’t contain preservatives that make it last longer. Organic produce is sometimes (but not always, so watch where it is from) produced on smaller farms nearer to where it is sold.
Organic farming tends to be better for the environment. Organic farming practices may reduce pollution, conserve water, reduce soil erosion, increase soil fertility, and use less energy. Farming without synthetic pesticides is also better for nearby birds and animals as well as people who live close to farms.
Organically raised animals are NOT given antibiotics, growth hormones, or fed animal byproducts. Feeding livestock animal products increases the risk of mad cow disease (BSE) and the use of antibiotics can create antibiotic-resistant strains of bacteria. Organically-raised animals tend to be given more space to move around and access to the outdoors, which help to keep them healthy.
Organic meat and milk can be richer in certain nutrients. Results of a 2016 European study show that levels of certain nutrients, including omega-3 fatty acids, were up to 50 percent higher in organic meat and milk than in conventionally raised versions.Some small local farmers use organic methods but may not be able to afford to become certified organic. Visit a farmer’s market and talk with the farmers to find out what methods they use. At the same time, we now have many ways to get organic plant extract.
