Sap activity, which transforms excess ingested sugar into long-chain oligosaccharides." A much larger set of animals do however consume phloem sap by proxy, either "through feeding on the honeydew of phloem-feeding hemipterans. Honeydew is physiologically less extreme than phloem sap, with a higher essential:non-essential amino acid ratio and lower osmotic pressure," or by feeding on the biomass of insects that have grown on more direct ingestion of phloem sap. Maple syrup is made from reduced sugar maple xylem sap. The sap often is harvested from the Sugar Maple, "Acer saccharum". In some countries (e.g., Lithuania, Latvia, Estonia, Finland, Belarus, Russia) harvesting
Sugary drink tax a targeted tax on sugary drinks at a national level in 2012; following introduction, soft drinks are estimated to be up to 3.5% more expensive. Analysis by the market research firm Canadean found that sales of soft drinks declined in the year following the introduction of the tax, following several years of annual growth. However, the tax applies to both drinks with added sugars and drinks with artificial sweeteners, possibly limiting its effects on the healthfulness of soda products. A 2016 study by Mazzochi has shown that the sugary drinks tax saw a 19 euro-cent per liter increase in price
