In 1999, researchers looked at the Nurses Health Study and found that eating nuts reduced the risk of heart disease by 30 percent. Substituting nuts for saturated fats resulted in a 45 percent reduction in risk.

Replacing almonds with saturated fats may help lower cholesterol levels. A study published in The American Journal of Clinical Nutrition found that men with normal cholesterol levels who supplemented their diet with almonds saw a 10 percent reduction in their LDL levels.

The study looked at people with high cholesterol. They ate a low-cholesterol diet that included one-third of a cup of almonds or a muffin with the same number of calories. After six weeks, participants switched to a different diet. The researchers found that the almond diet led to better distribution of cholesterol. The effects were only seen in people at a normal weight.

Almonds have a high amount of unsaturated fat and are high in plant sterols, which may interfere with the absorption of cholesterol and bile acid, according to Harvard.

A study of 12,000 adults, published in the Archives of Internal Medicine, showed that those who consumed 4,069 of the mineral each day had a lower risk of cardiovascular disease and ischemic heart disease than those who took 1,793 of the mineral per day.

Magnesium is important for heart health. According to the British Medical Journal, some doctors have seen positive results from giving patients magnesium to lower their blood pressure. There is a link between magnesium intake and lower heart disease risk in men.

A study published in 2004 in the American Journal of Epidemiolgy found that frequent nut consumers had a 30 percent decreased risk of developing gallstone disease.

There is cancer.

According to the review, some studies suggest a relationship between nut consumption and reduced cancer risk in women, but they do not focus on almonds. A 2001 animal study found that rats who ate almonds had fewer cancer cells in their colons.

The Third Expert Report and Continuous Update Project found limited evidence to draw conclusions about nuts and cancer risk. An analysis of large population studies found a 15% lower cancer risk for each ounce of nuts. Karen Collins, nutrition advisor to the American Institute for Cancer Research, wrote that studies that focus on specific types of cancer have found a reduced risk of colon, endometrial and Pancreatic cancer among people who eat more nuts.

The National Cancer Institute warns that the results from studies examining vitamins and cancer are not conclusive.

Almond growers in California were required to pasteurize their almonds after cases of salmonella were traced to almonds. Almonds grown in California have not been available. Almonds that are labeled as "raw" are actually Pasteurized with steam or propylene oxide. According to the Cornucopia Institute, organic farmers have sued the USDA over the practice.

The British Dietetic Association says that people who consume alternative milks, such as almond milk, could be at risk for iodine deficiency. Almond milk is often supplemented with calcium to make it more similar to cow's milk. Fetal brain development can be aided by the use of Iodine.
