For seniors over 74 years of age, putting them on a restrictive diet is….
New research has found that eating diets high in sugar and fat may not affect the health outcomes of older adults aged 75 and above, suggesting that placing people of such advanced age on overly restrictive diets to treat their excess weight or other conditions may have little benefit.
Gordon Jensen, head of the Department of Nutritional Sciences at Penn State who headed up the study stated that, "Historically people thought of older persons as tiny and frail, but that paradigm has changed for many older persons. Currently, 30 percent or more may be overweight, and by 2030, almost 30 percent are projected to be obese, not just overweight. Recent reports even suggest that there may be survival benefits associated with overweight and mild obesity status among the elderly."
The team’s research is part of a decades-long collaborative on the effects of nutritional status and diet on the health of more than 20,000 older people. In the current study, the team followed 449 individuals for five years who were on average 76.5 years old at the beginning of the study.
Jensen added that, "This is one of the first studies to examine obesity-related health outcomes and dietary patterns in such aged persons."
At study baseline, the team assessed the participants’ dietary patterns by calling each of them by telephone four or five times during a 10-month period and asking them about their diets over the previous 24 hours. The participants were categorized as adhering to one of three different dietary patterns.
The "sweets and dairy" pattern was characterized by the largest proportions of energy from baked goods, milk, sweetened coffee and tea and dairy-based desserts, and the lowest intakes of poultry. The "health-conscious" pattern was characterized by relatively higher intakes of pasta, noodles, rice, whole fruit, poultry, nuts, fish and vegetables, and lower intakes of fried vegetables, processed meats and soft drinks. The "Western" pattern was characterized by higher intakes of bread, eggs, fats, fried vegetables, alcohol and soft drinks, and the lowest intakes of milk and whole fruit.
Using outpatient electronic medical records, the researchers identified whether the participants developed cardiovascular disease, diabetes, hypertension and metabolic syndrome during the five-year period. They found no relationship between dietary pattern and prevalence of cardiovascular disease, diabetes, metabolic syndrome or mortality in the participants; however, they did find an increased risk of hypertension in people who followed the "sweets and dairy" pattern.
"We don’t know if the participants had been following these dietary patterns their entire adult lives, but we suspect they had been because people don’t usually change dietary practices all that much," Jensen said.
"The results suggest that if you live to be this old, then there may be little to support the use of overly restrictive dietary prescriptions, especially where food intake may already be inadequate. However, people who live on prudent diets all their lives are likely to have better health outcomes."
