DRAFT Australian Dietary Guidelines - Eat For Health

The evidence suggests that consumption of coffee is not associated with risk of coronary heart
disease (Grade C, Section 15.13 in Evidence Report [14]) [436-439], although this was not the
case for cigarette smokers.
Type 2 diabetes: There is evidence of a probable association between consumption of more than
four cups of coffee a day and a reduced risk of type 2 diabetes (Grade B, Section 15.15 in Evidence
Report [14]) [440-447]
Excess weight: It is probable that consumption of sugar-sweetened beverages is associated with
weight gain in children and adults (Grade B, Section 15.1 in Evidence Report [14]) [448-459] (see
Chapters 2 and 4).
2.6.2.2 Cancer
2.6.2.2.1 Cancer: Coffee
Bladder and lung cancer: The evidence suggests that consumption of coffee is associated with
increased risk of bladder cancer (Grade C, Section 15.10 in Evidence Report [14]) [460-462] and
lung cancer (Grade C, Section 15.12 in Evidence Report [14]) [463].
Breast, colorectal and ovarian cancer: The evidence suggests that consumption of coffee is not
associated with risk of breast cancer [464], colorectal cancer [294, 465-467] or ovarian cancer
[468-470] (Grade C, Section 15.7, 15.9, 15.11 in Evidence Report [14]).
Endometrial and hepatocellular cancer: The evidence suggests that consumption of coffee is
associated with decreased risk of hepatocellular cancer [471] and endometrial cancer [472, 473]
(Grade C, Section 15.6, 15.8 in Evidence Report [14]).
Gastric cancers: The evidence is inconclusive regarding an association between coffee
consumption and risk of gastric cancer (Section 15.5 in Evidence Report [14]).
2.6.2.2.2 Cancer: Tea
Ovarian and colorectal cancer: The evidence suggests that consumption of green or black tea is
not associated with ovarian cancer (Grade C, Section 15.18 in Evidence Report [14]) [468-470] or
colorectal cancer (Grade C, Section 15.19 in Evidence Report [14]) [465-467, 474, 475].
Other cancers: Recent evidence is inconclusive regarding an association between consumption of
green and black tea and breast, gastric or lung cancer (Section 15.16, 15.17 and 15.22 in Evidence
Report [14]).
