Here is another reason to make the tasty almonds a part of your daily diet. The humble tidbit nuts that combine tons of essential nutrients in one delicious package are an effective weapon in fighting type 2 diabetes and cardiovascular diseases, claims a new study. According to researchers, almonds added to the diet have a favorable effect on blood cholesterol levels and insulin sensitivity, two vital risk factors that can trigger diabetes and heart problems.
Lead author of the study, Dr. Michelle Wien, Assistant Research Professor in Nutrition at Loma Linda University’s School of Public Health stated, “We have made great strides in chronic disease research from evidence of effective treatment to evidence of effective prevention. “It is promising for those with risk factors for chronic diseases, such as type 2 diabetes and cardiovascular disease, that dietary changes may help to improve factors that play a potential role in the disease development.”
In a bid to assess the impact of almond enriched diet as a prescription for physical wellness, the researchers conducted a study. The focus of the study was to analyze the effect of the humble nut on the progression of type 2 diabetes and cardiovascular disease. The investigators enrolled a group of 65 adults comprising 48 women and 17 men with pre-diabetes in their mid-50s. The study subjects were split into two groups. As a part of the study, one group was assigned to almonds while the second formed the control group. The control group followed a diet recommended by the American Diabetes Association (ADA).The group assigned to almonds conformed to a similar diet but also added 20 percent calories from almonds. All the participants were asked to consume the same amount of calories from carbohydrate-containing foods, such as pasta, bread, and rice. However, those consuming the almond-enriched diet reported a lower intake of carbohydrate-containing food items.
After a period of 16 weeks, the investigators compared the insulin and cholesterol levels of both the groups. It was noticed that people consuming almond-enriched diet exhibited marked improvement in their insulin sensitivity and a dramatic reduction in LDL cholesterol as opposed to those eating the nut-free regular diet.
The study was conducted at the University of Medicine and Dentistry of New Jersey. The findings of the research are published in the ‘Journal of the American College of Nutrition
The new study looked into the effects of four different diet combinations on blood lipid metabolism, in 117 patients with metabolic syndrome.
In accordance with previous suggestions, the researchers found that a low-fat, high-complex carbohydrate diet had “several detrimental effects”, including significantly increasing total triglyceride levels, and triglyceride rich lipoprotein cholesterol levels.
In contrast, intake of the same diet supplemented with omega-3 was found to have no effects on blood lipid levels, with researchers observing that a diet rich in monounsaturated fats, or a low-fat diet rich in complex carbohydrates and omega-3 fatty acids, resulted in lower circulating blood lipid levels than a diet rich in high saturated fats or a diet low in fats and high in complex carbohydrates.
The data from the study suggest a place for higher omega-3 intake in people with metabolic syndrome, and supports previous research that suggests monounsaturated fatty acids can have a positive effect on blood lipid levels.
“The long-term effect of the low-fat, high-complex carbohydrate diet, pre vs. post intervention phases, showed several beneficial effects of long chain omega-3 PUFA supplementation,” stated the researchers.
“Our data suggest that long-term intake of an isocaloric, low-fat, high-carbohydrate diet supplemented with long chain omega-3 … have beneficial effects on postprandial lipoprotein response in patients with metabolic syndrome,”

Food-specific diets rely on the myth that some foods have special properties that can cause weight loss or gain. But no food can. These diets don't teach healthful eating habits; therefore, you won't stick with them. Sooner or later, you'll have a taste for something else – anything that is not among the foods you've been “allowed” on the diet.
The popular high-protein, low-carbohydrate diets are based on the idea that carbohydrates are bad,
that many people are “allergic” to them or are insulin-resistant, and therefore gain weight when they eat them. The truth is that people are eating more total calories and getting less physical activity, and that is the real reason they are gaining weight. These high-protein, low-carbohydrate diets tend to be low in calcium and fiber, as well as healthy phytochemicals (plant chemicals).
Some authors of these fad diets advise taking vitamin-mineral supplements to replace lost nutrients. However, supplements should “bridge the gap” in healthy eating and not be used as a replacement for nutrient-rich foods. Also, the authors of high-protein, low-carbohydrate diets advocate taking advantage of ketosis to accelerate weight loss. Ketosis is an abnormal body process that occurs during starvation due to lack of carbohydrate. Ketosis can cause fatigue, constipation, nausea, and vomiting. Potential long-term side effects of ketosis include heart disease, bone loss, and kidney damage.
Successful weight loss (losing weight and keeping it off for at least five years) is accomplished by making positive changes to both eating habits and physical activity patterns.
How can you spot a fad diet?
Weight-loss advice comes in literally hundreds of disguises. Most often the “new” and “revolutionary” diets are really old fad diets making an encore appearance. Examples of fad diets include those that:
- tout or ban a specific food or food group
- suggest that food can change body chemistry
- blame specific hormones for weight problems
Ten Red Flags That Signal Bad Nutrition Advice:
- Recommendations that promise a quick fix
- Dire warnings of dangers from a single product or regimen
- Claims that sound too good to be true
- Simplistic conclusions drawn from a complex study
- Recommendations based on a single study
- Dramatic statements that are refuted by reputable scientific organizations
- Lists of “good” and “bad” foods
- Recommendations made to help sell a product
- Recommendations based on studies published without peer review
- Recommendations from studies that ignore differences among individuals or groups
